Stroke

People who wish to look after their heart health are aware that regularly eating vegetables is key.

A new study from Edith Cowan University (ECU) in Joondalup, WA, in Australia finds that leafy greens and other vegetables high in nitrates in particular confer significant cardiovascular benefits.

Researchers found that daily consumption of a cup of vegetables rich in nitrates is associated with better heart health.

“Our results have shown that, by simply eating 1 cup of raw (or half a cup of cooked) nitrate-rich vegetables each day, people may be able to significantly reduce their risk of cardiovascular disease.”

– lead author Dr. Catherine Bondonno from ECU’s Institute for Nutrition Research

Green leafy vegetables high in nitrates include spinach, lettuce, arugula (also known as rocket), Chinese cabbage, and parsley. Non-leafy vegetables with strong nitrate content include radishes, fennel, and beet.

The researchers estimate that cooking reduces a vegetable’s nitrate content by about 50%, but that is still enough to promote heart health.

Dr. Bondonno said, “The greatest reduction in risk was for peripheral artery disease — 26% — a type of heart disease characterized by the narrowing of blood vessels of the legs. However,” she added, “we also found people had a lower risk of heart attacks, strokes, and heart failure.”

The authors note that their findings are consistent with four earlier studies.

Worldwide, roughly 17.9 million people die of heart disease each year. In the United States, it is the leading cause of death for “men, women, and people of most racial and ethnic groups,” according to the Centers for Disease Control and Prevention (CDC).

About 655,000 people in the U.S. die of heart disease every year — one out of every four deaths in the country.

The study appears in the European Journal of Epidemiology.

A long-term study

The researchers analyzed 23 years of data for 56,468 residents of Denmark who participated in the Danish Diet, Cancer, and Health Study. All individuals filled out a food frequency questionnaire, and the resulting data was cross-referenced against public health records.

Analysis revealed that people in the highest fifth of intake of vegetable nitrates exhibited a 2.58 mm Hg, or millimeters of mercury, lower systolic blood pressure — which is the first value in a blood pressure reading — compared with those in the lowest intake group (after adjustments for possible confounding differences between the groups).

The higher the nitrate intake, the greater the fall in blood pressure. The top intake group ate an average of 141 milligrams (mg) of nitrate per day. This is equivalent to 2–2.5 cups of leafy vegetables daily.

In contrast, the impact of nitrate intake on hospitalizations across all types of cardiovascular disease (CVD) plateaued at 59 mg per day. It did not increase with further nitrate intake.

Overall, there was a 15% reduction in CVD admissions over the 23 years of follow-up, compared with those with the lowest nitrate intake, which was 23 gm per day. The greatest reduction in risk — at 26% — was seen in hospitalizations for peripheral artery disease.

Speaking to Medical News TodayDr. Edo Paz of K Health, who was not involved in the research, said he considers the study significant due to its large sample size and lengthy follow-up period.

“However,” he noted, “this is an observational study, and there are some key limitations as a result.” He explained:

“In particular, it is highly likely that people who eat vegetables have other healthy behaviors that are different than those people who do not eat vegetables. For instance, these participants may be more likely to maintain a healthy weight, exercise more, smoke less, etc. Even though the authors try to account for these variables, this is still a key limitation inherent to observational studies in general.” – Dr. Edo Paz

Just a cup

The study suggests that the equivalent of a cup of raw or half a cup of cooked green leafy vegetables of this kind a day is just about the right amount for long-term heart health. “We did not see further benefits in people who ate higher levels of nitrate-rich vegetables,” said Dr. Bondonno.

“People don’t need to be taking supplements to boost their nitrate levels,” Dr. Bondonno said, “because the study showed that one cup of leafy green vegetables each day is enough to reap the benefits for heart disease.

Dr. Paz told MNT: “It’s important to remember that everything should be eaten or consumed in moderation. If extreme amounts of nitrate are ingested, it could lead to methemoglobinemia, which is a condition in which red blood cells have reduced ability to carry oxygen.”

“Fortunately, methemoglobinemia is relatively rare and is more commonly caused by nitrate contamination of drinking water.”

Dr. Bondonno does not recommend juicing vegetables if you want to enjoy the optimal nitrate benefit, since juicing removes pulp and fiber.

On the other hand, blending vegetables is fine. She recommends including a cup of spinach in a berry smoothie as an easy, enjoyable way for people to consume their vegetables.

Kidney cancer is the eighth most common cancer in adults, with just over 10,100 people diagnosed each year.

Signs and symptoms of kidney cancer can include: blood in your urine; a constant pain in your side, just below the ribs; and a lump or swelling in the kidney area (on either side of the body).

See your General Practitioner (GP) as soon as possible if you experience any of these symptoms. They will examine you and may refer you to a specialist clinic for further tests.

In around half of all cases of kidney cancer, there are no symptoms, and the condition is detected during tests for other unrelated conditions.

The kidneys and cancer
The kidneys are two bean-shaped organs located on either side of the body, just underneath the ribcage. Their main role is to filter out waste products from the blood, in addition to producing urine. Only one of the kidneys is usually affected by cancer.

The human body is made up of billions of cells, which normally grow and multiply in an orderly way, with new cells being created only when and where they’re needed. In cancer, this orderly process goes wrong and cells begin to grow and multiply uncontrollably.

Exactly what triggers this growth is unknown; however, there are certain risk factors that can increase the chances of the condition developing, such as smoking and obesity.

Kidney cancer most frequently affects people over 50 years of age and is more common among men.
Treating kidney cancer

The earlier kidney cancer is diagnosed, the easier it is to treat. How it is treated will depend on the size and spread of the cancer. Surgery to remove the cancerous cells is usually the first course of action.

Unlike most other cancers, chemotherapy isn’t very effective at treating kidney cancer. However, non-surgical treatments are available, such as radiotherapy or targeted therapies. These are most commonly used in the more advanced stages of kidney cancer, when the cancer has spread beyond the kidney.

Preventing kidney cancer
As the causes of kidney cancer aren’t fully understood, it is not possible to fully prevent it.

However, leading a healthy lifestyle may reduce the chances of developing the condition. A combination of a healthy diet and regular exercise will help to avoid becoming overweight or obese, which is a significant risk factor for kidney cancer.

If you are overweight or obese, you can lose weight and maintain a healthy weight by combining regular exercise with a calorie-controlled diet.

The unmistakable taste and smell of coffee — not to mention its ability to perk people up in the morning — have made it one of the world’s most popular beverages.

Better still, observational studies indicate that coffee may protect against cardiovascular disease, diabetes, Parkinson’s disease, and certain cancers.

Prospective studies, which follow people over time, have provided evidence that drinking this beverage is safe for most people and is associated with lower mortality rates.

However, a new study suggests that some of the supposed health benefits of coffee for cardiovascular health may have been overblown. The research was limited to white British participants.

As a result of the caffeine that coffee contains, excessive consumption can cause unpleasant symptoms such as tachycardia (a fast resting heart rate) and palpitations.

Drinking coffee can also lead to a moderate, temporary increase in blood pressure.

So it may come as a surprise that regular coffee drinkers either have normal or reduced blood pressure compared with people who do not drink coffee.

One explanation may be that coffee drinkers develop a physiological tolerance for the effects of caffeine.

But a new study suggests that people with a high genetic risk of cardiovascular disease unconsciously reduce how much they drink to avoid unpleasant cardiovascular symptoms.

The research found that individuals with high blood pressure, angina, or arrhythmia drank less caffeinated coffee and were more likely to drink decaffeinated coffee.

Crucially, there was strong evidence that their genetic vulnerability to cardiovascular disease led to their reduced consumption of coffee.

This rules out the alternative explanation that consuming less coffee made them more vulnerable to cardiovascular disease.

Researchers at the University of South Australia in Adelaide conducted the study, which appears in The American Journal of Clinical NutritionTrusted Source.

Guided by genetics

“Whether we drink a lot of coffee, a little, or avoid caffeine altogether, this study shows that genetics are guiding our decisions to protect our cardio health,” Professor Elina Hyppönen, who led the research and directs the Australian Centre for Precision Health at the university.

“If your body is telling you not to drink that extra cup of coffee, there’s likely a reason why,” she adds. “Listen to your body — it’s more in tune with your health than you may think.”

In observational studies, this effect could give the false impression that coffee prevents high blood pressure and protects the heart.

In reality, people vulnerable to high blood pressure may simply avoid drinking coffee because, for them, the caffeine is more likely to cause unpleasant symptoms.

The scientists drew on information about 390,435 white British participants aged 39–73 years who are part of a medical and genetic database called UK Biobank.

On recruitment, participants reported their regular coffee consumption. Researchers also measured their blood pressure and heart rate and noted any cardiovascular symptoms.

Participants with high blood pressure, angina, or arrhythmia consumed less caffeinated coffee compared with those without these symptoms.

To determine whether regular coffee consumption caused the symptoms, or whether the symptoms triggered a reduction in coffee consumption, the researchers used a statistical technique called Mendelian randomization.

This technique exploits the random inheritance of genetic variants that increase a person’s risk of a particular outcome later in life — in this case, the association between blood pressure and heart rate with habitual coffee consumption.

Because factors, such as lifestyle or diet, cannot change a person’s genetic sequence, any associations that the researchers discovered must be due to the gene variants rather than any other factors.

When they analyzed the data, it showed that having a particular genetic variant determined how much coffee a person drank.

“What this means is that someone who drinks a lot of coffee is likely more genetically tolerant of caffeine, as compared to someone who drinks very little,” says Prof. Hyppönen.

“Conversely, a noncoffee drinker, or someone who drinks decaffeinated coffee, is more likely prone to the adverse effects of caffeine and more susceptible to high blood pressure,” she adds.

Psychological effects

Medical News Today asked Prof. Hyppönen whether the psychological effects that some people experience when they drink a lot of coffee, such as anxiety and agitation, could also play a role.

“This is not something that we looked at in our study, but any unpleasant sensation that an individual feels in response to coffee consumption is likely to reduce their wish to drink coffee,” said Prof. Hyppönen.

MNT asked Dr. Edo Paz, a doctor atdigital primary care platform K Health, about the effects of drinking too much coffee.

He responded:

“[D]rinking too much coffee can result in headache, anxiety, tremors, and difficulty sleeping. With regards to the heart, in particular, excess coffee intake can result in palpitations and may trigger events in the heart, such as abnormal heart rhythms, in susceptible individuals.”

The problem of reverse causation

The findings of the new research suggest that observational studies that found an association between coffee consumption and better health may have fallen prey to “reverse causation.”

In other words, heart health issues led people to drink less coffee, rather than the other way round.

Prof. Hyppönen said Mendelian randomization studies had cast doubt on other apparent protective effects.

For example, epidemiological studies have led people to infer that moderate alcohol consumption protects against cardiovascular disease, and that having excess weight reduces mortality compared with moderate weight.

“According to [Mendelian randomization] studies, there does not appear to be any benefit for having [excess weight] versus [slim or moderate] weight, with the possible exception for smokers,” she said.

Smoking reduces appetite and hence weight, but it also has links with a wide range of negative effects on health.

“Also for alcohol, [the] evidence suggests linear increases in blood pressure and stroke risk, with no benefit for light alcohol consumption,” she added.

While further studies are necessary using a more diverse population, this study suggests using a considered, personalized approach when promoting high coffee intakes.

There have been numerous investigations into a possible role for vitamin D in preventing both SARS-CoV-2 infections and COVID-19 complications.

These studies have drawn conflicting conclusions. Now, a study from researchers in Brazil provides a more robust answer to at least one key question: can vitamin D help prevent COVID-19 complications in particularly ill hospitalized patients? According to the results, the answer appears to be no.

The study found that high doses of vitamin D administered to hospital patients with moderate or severe COVID-19 did not affect the course of the disease.

“In vitro studies or trials with animals had previously shown that in certain situations, vitamin D and its metabolites could have anti-inflammatory and antimicrobial effects, as well as modulating the immune response,” explains Rosa Pereira, principal investigator for the study.

“We decided to investigate whether a high dose of the substance could have a protective effect in the context of an acute viral infection, reducing either the inflammation or the viral load.”

Based on the study’s results, says Pereira, “So far, we can say there’s no indication to administer vitamin D to patients who come to the hospital with severe COVID-19.”

The research appears in JAMA.

COVID-19 and vitamin D

Scientists at the University of São Paulo’s Medical School (FM-USP) in São Paulo, Brazil, conducted the randomized, double-blind, and placebo-controlled clinical trial. The researchers say this study is the first of its kind.

The team tracked the experiences of 240 volunteers receiving treatment for COVID-19 symptoms at FM-USP’s Hospital das Clínicas and the Ibirapuera Park field hospital in São Paulo City, from June to August 2020. All participants had tested positive for SARS-CoV-2 using a polymerase chain reaction test or via antibody testing.

All of them received treatment with standard COVID-19 protocols that include antibiotic and anti-inflammatory medications. The researchers then divided them into two equal groups at random.

The scientists gave participants in the first group a single 200,000-unit dose of vitamin D3 dissolved in peanut oil. They gave those in the second group unaltered peanut-oil placebos.

The design of the study was to discover whether a high dose of vitamin D was associated with a shorter hospitalization — the researchers found that it was not.

The investigation also found no evidence that vitamin D made a person less likely to be admitted to the intensive care unit or less likely to need intubation.

Vitamin D also seemed to have no effect on mortality, although Pereira cautions that a larger study with more participants is required before researchers can draw final conclusions.

More vitamin D studies needed

The study conclusively rules out vitamin D as a “magic bullet” for treating COVID-19.

Co-author Bruno Gualano, a researcher at FM-USP, says, “But that does not mean continuous use of vitamin D cannot have beneficial effects of some kind.”

Having suggested that a single high dose of vitamin D is not a solution to severe COVID-19, Pereira is now leading a new study to determine whether a vitamin D deficiency has any effect on a person’s ability to overcome SARS-CoV-2.

Pereira is also looking to establish the amount of vitamin D a person should have in their bloodstream to promote good health. This threshold will vary depending on an individual’s characteristics. Younger, generally healthy people should have at least 20 nanograms per milliliter of blood (ng/ml). Whereas for older people, for example, and those with osteoporosis, the minimum is 30 ng/ml.

Pereira says, “The ideal approach is case-by-case analysis, if necessary dosing the substance periodically by means of blood work, with supplementation if a deficiency is detected.”

Lagos State Commissioner for Health, Akin Abayomi, has said that government plans to commission a modern 500-bed capacity mental healthcare facility for admission and rehabilitation of psychiatric patients.

Abayomi made the disclosure on Wednesday while speaking at the Eko Wellness Fair. The event will hold from Saturday, May 1 to Friday, May 7 virtually.

He noted that mental health should be given priority, considering the pressure and other challenges that residents of the state are subjected to on a daily basis.

Abayomi disclosed that plans are ongoing to establish mental health units in all general hospitals while the government works on improving recreation facilities across the state to achieve Lagos State’s one health initiative.

Convener, Eko Wellness Network, Oyin Talabi, explained that the fair aims to connect people with wellness practitioners as a preventive instead of curative measure.

She noted that series of events in the nation since 2020 suggests that many Nigerians are in a survival mode, making it difficult for people to think critically for optimal productivity.

The fair tagged “My Mental Health Matters: For Our Collective Prosperity” will feature workshops by high-level Nigerian psychotherapists and wellness practitioners, cooking demonstrations of healthier food alternatives, art and therapy stimulations, and online shopping of healthy foods and lifestyle products by proudly Nigerian businesses.

According to Talabi, Nigeria is yet to scratch the surface in creating mental health awareness. She called for more engagement as there are still depths to cover in healthy living.

Talabi called on the government to enact laws that support the mental health of citizens as the “existing ones are archaic.”

“A part of the law permits arrest of an individual if found mentally unstable, and displaying in a public place instead of getting the person help,” Talabi said.

Zainab Abu, Vertical Lead, SMEs, Flutterwave, noted that the change in consumer behaviour since the pandemic informed their partnership with the fair.

“As partners we are helping all vendors display goods and facilitate online payment,” Abu said. “We are creating an avenue for them to display their goods virtually during the event and receive payment from every purchase. The platform allows them to put up pictures description and amount of products on sale.”

Africa Film Awards, the curators of the AMA-Awards, also partnered with the Eko Wellness Network to amplify awareness for mental health through a short film contest. The 7 top films will be screened on each day of the week-long fair.

Eating fruit is a delicious way to satisfy hunger and meet daily nutritional needs. However, most fruits contain sugar. This has raised questions about whether fruits are suitable for people who have diabetes.

Diabetes is a chronic but manageable condition in which the body struggles to control the levels of blood sugar.

Is fruit dangerous for people with diabetes? This article will suggest fruits to eat and avoid if you have diabetes, as well as examining the relationship between fruit and blood sugar.

List of fruits for diabetes

fruits for diabetes on heart shaped platter
People with diabetes can eat fruit.

Below is a list of fruits divided by GI index, as reported by the U.S. Department of Agriculture (USDA).

Low GI and GL fruits

Some fruits have a GI of under 55 and a GL under 10, including.

  • apples
  • avocados
  • bananas
  • berries
  • cherries
  • grapefruit
  • grapes
  • kiwi fruit
  • nectarines
  • orange
  • peaches
  • pears
  • plums
  • strawberries

Medium-GI fruits (GI of 56 to 69)

A fruit with a GI of between 56 and 69 is considered to be a medium-GI food. All fruits listed below still have GL levels under 10.

  • honeydew melon
  • figs
  • papayas
  • pineapples

High-GI fruits

Fruits with a GI higher than 70 are high-GI and a GL of greater than 20 is high GL. While these are safe to eat with diabetes, it is important to eat larger quantities of lower-GI fruits instead.

  • dates (high GL)
  • watermelon (low GL)

Fruit and diabetes

The American Diabetes Association (ADA) advises that any fruit is fine to eat for a person with diabetes, so long as that person is not allergic to a particular fruit.

meta-analysis published in 2014 in the British Medical Journal found higher fruit intake was significantly associated with a lower risk of type 2 diabetes.

The preparation of fruit, however, can affect blood sugar. Fresh or frozen fruits are better than processed fruits straight from a can or jar, such as applesauce and canned fruit. Processed fruits also include dried fruit and fruit juices.

People with diabetes should eat processed foods sparingly or avoid them completely. The body absorbs processed fruits more rapidly, leading to higher blood sugar levels. Processing fruits also removes or reduces levels of certain key nutrients, including vitamins and fiber.

The National Institute of Diabetic and Digestive and Kidney Diseases (NIDDK) recommends that people with diabetes should avoid fruit juices or canned fruits with added sugar.

Fruit blends like smoothies also have high sugar content and are more rapidly absorbed leading to higher spikes in blood sugar.

What is the glycemic index?

For a person with diabetes, one way to select safe and suitable fruits and other high-carbohydrate foods is to check the glycemic index (GI).

GI is a rating of foods on a scale from 1 to 100. The score indicates how quickly the food item may raise blood sugar levels.

High GI foods are absorbed faster than medium or low GI foods.

Glycemic load (GL) takes into account the GI of a food plus the number of carbohydrates in a serving. GL may be a more accurate way of assessing how food affects blood sugar management over time. Low-GI and low-GL foods are better for helping control blood sugar levels.

People may be surprised to learn that many fruits have a low glycemic index. People digest starchy vegetables, such as potatoes and grains, more rapidly, so these have a higher GI index.

The longer a carbohydrate-rich food is cooked, the higher the GI value. Fat, fiber content, and cooling carbohydrates after they have been transformed into resistant starches via cooking can all dramatically lower GI values.

Benefits for diabetes

Fruit plays a key role in helping people with diabetes feel full and absorb sugar slowly.

Eating enough fiber plays an important role in managing diabetes.

A diet high in soluble fiber can slow the absorption of sugar and control its levels in the blood. Many fruits are high in fiber, especially those with the skin or pulp included.

Many fruits are filling because of their high fiber and water content.

Diets containing enough fruits and vegetables can reduce the risk of obesityheart attack, and stroke. Obesity has been linked to type 2 diabetes.

Fruits are high in fiber and nutrients, so they are a good choice in meal planning. Fruits that have been processed such as applesauce and fruit juices have had their fiber removed and should be limited.

Other health benefits of fruit

The good news is that fruit is healthy to eat for people with diabetes, according to the NIDDK.

People with diabetes should eat a balanced diet that provides enough energy and helps to maintain a healthy weight. Some fruits are high in sugar, such as mangoes, but can be part of a healthy diet in moderate amounts.

Fruits can also satisfy a sweet tooth without resorting to candy and other foods with low nutritional value. Most fruits are high in nutrients and low in fat and sodium. Fruits also often contain nutrients not found in other foods.

Bananas contain potassium and tryptophan, an important amino acid. Citrus fruits like oranges and grapefruits are high in vitamins A and C, which are powerful antioxidants.

How much fruit should I eat?

Most guidelines recommend that adults and children eat five servings of fruits and vegetables each day. This does not change for people with diabetes.

The United States guidelines recommend that people fill half of their plate at each meal with fruits and vegetables.

People with diabetes should focus on non-starchy vegetables for 50 percent of the meal, rather than depending on fruit. The remaining half of the meal should be protein and high-fiber starches like beans or whole grains. Many experts also recommend including healthy fat at each meal to encourage feeling full and enhance absorption of antioxidants and vitamins.

One serving is a medium-sized fruit, or a serving the size of a baseball. Smaller fruits, such as berries, have one-cup as the serving size.

A half-cup is also the serving size for processed fruit products, such as applesauce and fruit juice. The serving for fried fruits like raisins and cherries is 2 tablespoons per serving size.

Like vegetables, it’s great for people to eat a variety of fruits to get their needed nutrients, as well as to enjoy their varied flavors.

Dietary tips

To achieve the desired five servings of fruits and vegetables per day, people should aim to have fruit or vegetables throughout the day.

Here are a few ideas to help with menu planning:

Citrus fruits

Citrus fruits are versatile and easy to add to meals. Add lemons and limes to seafood, sauces, or glasses of iced tea or water.

People can make their own fruit water by adding citrus slices to a pitcher of water. Let the water sit overnight to create a refreshing drink.

Berries

Berries are tasty when eaten raw and can also be cooked into a compote to spoon into oatmeal or meat.

Put whole fresh or frozen berries into a saucepan with a tablespoon or two of water. Cook on medium or low heat until the berries have broken down into a thick sauce.

One serving is half a cup.

Apples

Apples are a popular fruit. They are delicious raw for a snack or dessert. When cooked, apples have a deeper flavor, making them a favorite in cooked desserts when spiced with cinnamon or ginger.

recipe from the ADA suggests marinating apples in a small amount of honey and spices and then cooking them on a grill. To finish, roll the apples in crushed walnuts or pecans.

While still containing honey, this is a healthier alternative to many apple-based baked goods.

Avocados

Avocados are high in fat, but they contain monounsaturated fat, the type of fat that is beneficial for the body.

They are eaten raw and can be served sliced, in salsas, or as guacamole. Avocados are easy to prepare by slicing them in half around the pit. Discard the pit and mash the avocado.

Add herbs and vegetables to taste. Lime or lemon can also be added to avocado for a citrus boost.

According to the World Health Organization (WHO), cancer accounted for 10 million deaths worldwide in 2020. Globally, it is a leading cause of death.

In the United States, an estimated 39.5% of people will receive a cancer diagnosis within their lifetime.

Myths tend to develop around particularly prevalent conditions. It is no surprise, therefore, that people often misunderstand cancer.

“Cancer” is a generic term for a group of diseases that can affect any part of the body. This variety adds fuel to the fire of confusion.

In this article, we hope to dispel some myths and clarify this common and varied group of diseases.

1. Cancer is a death sentence

Cancer is not a death sentence. Despite the sobering statistics quoted above, cancer is not always terminal.

As scientists understand cancer better and develop improved treatments, recovery rates continue to improve.

For instance, in January 2019, an estimated 16.9 million cancer survivors were living in the United States. In the United Kingdom, survival rates have doubled in the last 40 years.

It is also worth noting that survival rates vary significantly depending on the type of cancer. For instance, in the U.K., survival rates for testicular cancer are 98%, whereas survival rates for pancreatic cancer are just 1%.

According to the National Cancer Institute:

“In the United States, the likelihood of dying from cancer has dropped steadily since the 1990s. Now, 5-year survival rates for some cancers, such as breast, prostate, and thyroid cancers, are 90% or better. The 5-year survival rate for all cancers combined is currently about 67%.”

Overall, cancer death rates are slowly declining, although the survival rates of some cancers are increasing more than others. An annual report on the status of cancer in the U.S., which appears in Cancer in 2020, concludes:

“[C]ancer death rates decreased 1.5% on average per year during 2001 through 2017.”

2. Cancer is contagious

This is a myth. Cancer is not contagious. Someone with cancer cannot spread it to others.

However, some sexually transmitted diseases, including human papillomavirus (HPV) and hepatitis B and C, can cause cancers in the cervix and the liver. In these cases, an infectious agent causes the cancer, but the cancer itself is not contagious.

As an interesting aside, scientists have documented that cancers in some animals, including Tasmanian devils and dogs, can cause fatal transmissible cancers: devil facial tumor disease and canine transmissible venereal tumor, respectively.

3. Cell phones cause cancer

To date, there is no evidence that cell phones cause cancer. One of the reasons this myth developed is that these devices emit radiofrequency radiation (radio waves), a form of non-ionizing radiation. The body absorbs this radiation.

Scientists know that exposure to ionizing radiation, for instance, X-rays, increases the risk of cancer. However, radiofrequency radiation is non-ionizing radiation, which does not increase cancer risk. The National Cancer Institute writes:

“[A]lthough many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans.”

4. Power lines cause cancer

This is also a myth. The extremely low frequency (ELF) magnetic fields produced by power lines are non-ionizing and, therefore, do not cause cancer.

The American Cancer Society writes:

“Several large studies have looked at the possible effects of ELF magnetic fields on cancer in rats and mice. These studies expose the animals to magnetic fields much stronger than what people are normally exposed to at home […]. Most of these studies have found no increase in the risk of any type of cancer. In fact, the risk of some types of cancer was actually lower in the animals exposed to the ELF radiation.”

However, the American Cancer Society also explains that some studies have found a slight increase in leukemia risk for children who live close to power lines. However, the reasons for this remain unclear.

Medical News Today spoke with Dr. Joel Newman, a consultant hematologist and specialty lead for pathology at East Sussex Healthcare Trust in the U.K. He puts the risk into perspective:

“We don’t have any real evidence that cell phones or power lines cause cancer, and there are many other things that we do daily that put us at a much greater risk than these ever could, including smoking and alcohol consumption.”

5. Artificial sweeteners cause cancer

To date, there is no good evidence that artificial sweeteners increase the risk of developing cancer.

The National Cancer Institute explains why this myth may have arisen:

“Questions about artificial sweeteners and cancer arose when early studies showed that cyclamate in combination with saccharin caused bladder cancer in laboratory animals.”

However, they explain that further studies “have not provided clear evidence of an association with cancer in humans. Similarly, studies of other [Food and Drug Administration (FDA)]-approved sweeteners have not demonstrated clear evidence of an association with cancer in humans.”

Similarly, a study investigating aspartame and cancer, which included data from more than half a million participants, found no links between “aspartame consumption and lymphoma, leukemia, or brain cancer.”

6. Cancer surgery causes cancer to spread

This is only a partial myth. It is true that cancer surgery can cause the cancer to spread, but this is rare. As the American Cancer Society explains:

“Advances in equipment used during surgery and more detailed imaging tests have helped make this risk very low.”

A related myth indicates that a tumor will grow faster or spread to other parts of the body when exposed to the air. This is untrue.

7. Herbal medicines can cure cancer

There is no evidence that any herbal medicines can cure or treat cancer.

However, some people find certain alternative therapies, such as acupuncture, meditation, and yoga, help with the psychological stress associated with cancer and some of the side effects of cancer treatment.

As the National Cancer points out, just because something is “natural” does not mean it is safe. In some circumstances, herbal supplements can harm a person’s health; they provide a couple of examples:

“[S]ome studies have shown that kava kava, a herb that some people use to help with stress and anxiety, may cause liver damage. And St. John’s wort, which some people use for depression, may cause certain cancer drugs not to work as well as they should.”

It is important that people with cancer speak with a doctor about supplements and vitamins before taking them.

8. Cancer runs in families

Although some cancers are passed on genetically through families, they are the minority of cases: an estimated 3–10% of cancers result from mutations inherited from parents.

Because people are more likely to develop cancer as they age, and people today live longer lives, it is not uncommon for people to have some relatives who develop cancer. This might help explain why this myth persists.

Most cases of cancer are due to a buildup of mutations in genes that accumulate over time. As the American Cancer Society explains:

“Some types of cancer run in certain families, but most cancers are not clearly linked to the genes we inherit from our parents. Gene changes that start in a single cell over the course of a person’s life cause most cancers.”

9. Cancer always comes back

To address this question, MNT spoke with Dr. Collin Vu, a medical oncologist and hematologist at MemorialCare Cancer Institute at Orange Coast Medical Center in Fountain Valley, CA. He said:

“Fortunately for all of us, this statement is a myth and entirely not true. The current therapies for cancers are improving to the point where the cure of cancer — that is, treatments that will kill cancer completely — are improving continuously.”

However, he explains that the subject is complicated because “different cancer types have a markedly different ability to be cured, and different cancer types also have different time frames for which a cancer may typically recur. [This] makes it very difficult for patients to know when they may be truly ‘cured’ or when they still have a high risk of cancer recurrence.”

Dr. Vu has great hopes for the future of cancer treatment; he told MNT:

“In the future, with current scientific progress in better treatments for cancer, and improved population awareness of cancer risks and diagnosis, the statement that ‘cancer always comes back’ may become even more of a myth.”

10. There is no cure for cancer

Thankfully, this is also a myth. As medical science delves deeper into the mechanisms behind cancer, treatments steadily grow more effective.

According to Dr. Vu, some cancers, such as testicular and thyroid cancer, have a 60% cure rate. Dr. Vu defines the cure rate as “the population of cancer patients that has the same life expectancy as the general population.”

Breast, prostate, and bladder also have cure rates of around 50%. Dr. Vu concludes:

“As can be seen by the above data, some cancers can be eradicated, but, unfortunately, not all cancers can be cured completely. There is ongoing optimism that cure rates are increasing given the ongoing focus on screening and better treatments for cancer.”

MNT also spoke with Dr. Anton Bilchik, Ph.D., a surgical oncologist, professor of surgery, chief of gastrointestinal research, and chief of medicine at Saint John’s Cancer Institute at Providence Saint John’s Health Center in Santa Monica, CA. He also leads with a message of hope:

“It is imperative that patients who are diagnosed with cancer, even at an advanced stage, do not lose hope: there are many effective, novel therapies, as well as more effective surgical techniques. A good example is with the use of modern immunotherapy, up to 40% of patients with stage 4 melanoma are curable, and 50% of patients with stage 4 colon cancer metastatic to the liver can be cured with a combination of chemotherapy and surgery.”

In short: although the battle with cancer is ongoing, science is making significant headway.

Schizophrenia is a psychiatric condition that is characterized by “positive” symptoms, such as hallucinations and delusions, and “negative” symptoms, such as social withdrawal and apathy.

For almost a century, scientists have speculated about a possible link between the immune system and schizophrenia.

Several lines of evidence suggest that the inflammation provoked by a viral infection, either before birth or during childhood, could trigger the condition in adulthood.

Some studies have also found changes in the blood-brain barriers of people with schizophrenia.

The blood-brain barrier comprises the tightly packed layer of cells that line the blood vessels in the brain and spinal cord. It prevents blood-borne immune cells from gaining entry to the central nervous system.

This is sometimes known as conferring “immune privilege” on the brain — in other words, protecting it from harmful inflammation.

Researchers at the University of Pennsylvania’s School of Veterinary Medicine in Philadelphia wondered whether a compromised blood-brain barrier in people with a rare genetic disorder known as DiGeorge syndrome or 22qDS, a genetic deletion syndrome, could be responsible for their increased risk of schizophrenia.

People born with the condition have a 1 in 4 risk of developing schizophrenia later in life. This is compared with an overall risk of schizophrenia of around 1 in 100 in the wider adult population.

People with 22qDS have a small section of DNA missing from chromosome 22 of their genome.

Leaky barrier

To test their hypothesis, the researchers isolated cells from people with DiGeorge syndrome and schizophrenia and from healthy matched controls. They then turned these cells into pluripotent stem cells, which can develop into any type of cell in the body.

In the laboratory, they transformed the stem cells into the type of cells that line the blood vessels in the brain. These are the cells that together function as the blood-brain barrier.

The researchers found that the cells derived from people with DiGeorge syndrome and schizophenia created a less effective, more “leaky” barrier than those derived from the healthy controls.

In addition, the cells produced more of a type of molecule that promotes inflammation. This allowed more immune cells to penetrate the barrier.

The researchers obtained similar results when they investigated the integrity of the blood-brain barrier in a mouse model of DiGeorge syndrome.

Finally, they performed the same tests in postmortem brain tissue from three people who had DiGeorge syndrome and from three age-matched healthy controls.

They found evidence that the effectiveness of the actual blood-brain barrier of these people had indeed been compromised.

The research, which doctoral student Alexis Crockett led, now appears in the journal Brain.

Other brain disorders

The study authors speculate that a compromised blood-brain barrier may interact with environmental or other genetic risk factors to increase the likelihood not only of psychosis but also of other brain disorders in the case of people with DiGeorge syndrome.

“[W]e think these findings could also be used to understand how the blood-brain barrier and neurological processes impact not only schizophrenia but mental disorders at large,” says senior study author Prof. Jorge Iván Alvarez, from the School of Veterinary Medicine.

In 2019, Medical News Today reported on a study that suggested that a faulty blood-brain barrier in aging mice triggered brain inflammation and cognitive impairment in the animals.

Prof. Alvarez speculates that further research into the link between inflammation and neuropsychiatric disease could lead to new therapies for these conditions.

Anti-inflammatory and immunotherapy drugs have already shown some promise as treatments for schizophrenia, alongside standard treatments.

Schizophrenia is multifactorial

It is worth noting that schizophrenia is a “multifactorial” condition. This means that there is no single, clear cause. Rather, a wealth of different genetic and environmental influences interact to increase or decrease an individual’s risk of developing it.

Prof. Alvarez told MNT that people with the DiGeorge syndrome “phenotype” — that is, the characteristics arising from interactions between genetics and environment — will respond negatively to particular environmental challenges.

“These might include prenatal infection in the mother, or an infection in childhood.”

This “second hit” would worsen their condition in distinctive ways. “In terms of a ‘second hit,’” he said, “we believe that such environmental challenges will exacerbate the phenotype described under [steady] conditions.”

In their paper, Prof. Alvarez and colleagues also report some limitations of their study.

For example, their experiments did not prove that everyone with DiGeorge syndrome has a compromised blood-brain barrier. There remains a possibility that the changes are only present in those who develop schizophrenia.

To test this possibility, Prof. Alvarez said that he and his team would repeat the experiments using pluripotent stem cells from people who have this particular genetic deletion syndrome but have not developed schizophrenia.

“[W]e are planning to run these experiments using deleted non-schizophrenia [stem cells],” he said.

Obesity can have severe effects on a person’s quality of life and lifespan. Research shows that it substantially increases the risk of a wide range of diseases, including type 2 diabetes, cardiovascular disease, and some cancers.

Despite the long-established health risks, however, recent decades have seen an inexorable rise in rates of obesity throughout the world.

One study found that between 1980 and 2015, the prevalence of obesity doubled in more than 70 countries and steadily increased in most others.

According to the World Health Organization (WHO), in 2016, more than 650 million adults had obesity. Overweight and obesity now claim the lives of more than 2.8 million people each year.

A major challenge for researchers is to distinguish the effects of genetics from those of lifestyle on the progression of obesity and its effects on health.

A team of researchers, led by two from the Obesity Research Unit at the University of Helsinki, in Finland, used an ingenious way to do this.

By studying 49 pairs of identical twins who did not share the same body mass index, or BMI, readings, they removed the effect of genes from the equation.

Identical, or monozygotic, twins have the same genetic makeup. They experience almost identical conditions in the womb and usually have very similar upbringings.

This means that the differences between the twins in the study arose from the influence of their environment or lifestyle as adults, rather than their genes or conditions during childhood.

The researchers have published their findings in the journal Cell Reports Medicine.

Biopsies of fat and muscle

First, the researchers took blood samples and biopsies of fat, or adipose, tissue and skeletal muscle tissue from the volunteers.

They then used a variety of molecular techniques to analyze the transcription of genes, production of proteins, and processing of metabolites in the two types of tissue.

A key finding was that the activity of mitochondria, the power plants of cells, was reduced in the muscle and adipose tissue of people with obesity.

The change was more marked in adipose than in muscle tissue.

Meanwhile, there was also increased inflammation in the tissues from twins with obesity, compared with their leaner siblings.

The changes in adipose tissue, but not muscle tissue, were associated with adverse health effects, including fatty liver disease and insulin resistance, conditions that have been linked to the development of diabetes.

Reduced power output

“If mitochondria […] are compared to the engine of a car, you could say that the power output decreases as weight increases,” explains senior author Prof. Kirsi Pietiläinen, also of the university’s Obesity Research Unit.

The researchers believe that these underperforming mitochondria produce more of the harmful reactive oxygen species, or free radicals, that stoke inflammation.

“A low-powered mitochondrial engine may also generate toxic exhaust fumes, which can cause a pro-inflammatory state in adipose tissue and, consequently, the onset of diseases associated with obesity,” explains Prof. Pietiläinen.

“What was surprising was that the mitochondrial pathways in muscle had no association with these adverse health effects,” she adds.

Another notable finding was that mitochondria in the adipose and muscle tissue of individuals with obesity were less efficient at breaking down a type of amino acid. These acids are the building blocks of proteins.

“This finding was of particular significance because the reduced breakdown of these amino acids and the resulting heightened concentration in blood have also been directly linked with prediabetic changes and the accumulation of liver fat in prior twin studies,” says Prof. Pietiläinen.

The researchers observe that in people with obesity, excessive nutrients may upset the control of catabolic and anabolic processes, reactions that break down and assemble organic molecules, respectively.

They write:

“We argue that, because of a high nutrition load, adipose tissue and skeletal muscle tissue no longer sufficiently shift between catabolic and anabolic reactions in acquired obesity. Consequently, the cells in these tissues increase their [internal] communication and activate emergency responses, such as inflammation.”

They acknowledge that the major limitation of their study was its cross-sectional design, meaning that it focused on a single point in time.

While the study identified associations between obesity and the various metabolic and health measures, it could not prove the existence of any causal relationships, as a result of this design

The miracle tree, Moringa, Moringa Oleifera, or the drumstick is a plant recognized for its medical properties. It is used to treat more than 300 conditions. All parts of the Moringa tree possess some medicinal or nutritional value” says Amrit Walia ( Amritpal Singh Walia ) Co-Founder of Pioneer Sustainable Agriculture PSA organic farm located in Nigeria.

One cup of fresh, chopped leaves contains protein, Vitamin B6, Vitamin C, Iron, Magnesium, Riboflavin, and Vitamin A.

In this article, you will be able to understand the five prime uses of Moringa leaf that clearly distinguished it as an extraordinary species:

1. Moringa Leaf is Rich in Antioxidants
Moringa acts to reduce high levels of free radicals which may cause oxidative stress leading to diseases like type 2 diabetes or heart disease.

The basic antioxidants in Moringa are beta-carotene and Vitamin C. The exact figure of the number of antioxidants in the Moringa herb is staggering.

A few antioxidants present include propyl gallate, tocopherols (Vitamin E), ascorbic acid, chlorogenic acid, hydroxyanisole (BHT) citric acid, vanillin, potassium, reduced glutathione, and more. Quercetin is also present and crucial in the regulation of blood pressure.

2. Moringa Leaf Regulates Blood Sugar
Moringa herb produces effects similar to isothiocyanates plant compounds able to regulate blood sugar.
Sufficient research shows a significant reduction in blood sugar after short-term use of the herb with meals.

For instance, it was discovered that a group of diabetics who added 50 grams of moringa leaves to a meal reduced the rise in blood sugar by 21%.

3. Moringa Leaf Works to Reduce Inflammation
If you incur injury and develop wounds, Moringa can help you to stop inflammation.

Moringa is stocked with nutrients and antioxidants which are found in other anti-inflammatory foods like tomatoes, fatty fish, olive oil, and certain fruits.

By fighting harmful free radicals, the herb prevents sustained inflammation which can result in chronic problems like cancer or heart disease.

4. Moringa Leaf Promotes Prostate Health and Cure ED
The leaves and seeds of the Moringa plant are rich sulfur-containing compounds called glucosinolates, which fight cancer in the body, more specifically, benign prostate hyperplasias.

The condition which is prone to attack elderly man is characterized by enlargement of the prostate which makes urination difficult. Moringa can reverse the effects of prostate cancer by significantly reducing prostate weight.

The herb also reduces levels of prostate-specific antigen which is produced by the prostate gland.

Moringa can also cure erectile dysfunction. Its leaves contain useful plant compounds called polyphenols which enhance blood flow by increasing nitric oxide production while simultaneously lowering blood pressure.

Conclusion
The points discussed above show how versatile Moringa leaf is in the fields of health and medical care. The plant can be used for detoxification and in the treatment of digestive disorders.

The list of other ailments this wonder plant can treat include the following – scurvy, kidney stones, Athlete’s foot, dandruff, epilepsy, paralysis, convulsions, splenomegaly, epilepsy, antispasmodic, joint pain, edema, rheumatism, arthritis, cardiac hypertrophy, coronary artery disease, myocardial infarction, heart failure, and many more.
