Can we shake the Coronavirus to death? New Way to Kill Viruses: Shake Them to Death

Hidden knowledge, alternative healing, big pharma

Why couldn’t I find follow ups on this subject?

Royal Raymond Rife began researching on this subject in 1920.

It is widely accepted that, in 1920, Royal R Rife began his experiments using electronic frequencies on viruses and bacteria. Previous to that time, microbes were invisible, but using his own powerful microscopes, he was able to see them.

New Way to Kill Viruses: Shake Them to Death

By  

3D model coronavirus

Scientists may one day be able to destroy viruses in the same way that opera singers presumably shatter wine glasses. New research mathematically determined the frequencies at which simple viruses could be shaken to death. 
“The capsid of a virus is something like the shell of a turtle,” said physicist Otto Sankey of Arizona State University. “If the shell can be compromised [by mechanical vibrations], the virus can be inactivated.” 
 

“Experiments must just try a wide variety of conditions and hope that conditions are found that can lead to success,” Sankey told LiveScience.

To expedite this search, Sankey and his student Eric Dykeman have developed a way to calculate the vibrational motion of every atom in a virus shell. From this, they can determine the lowest resonant frequencies. 
As an example of their technique, the team modeled the satellite tobacco necrosis virus and found this small virus resonates strongly around 60 Gigahertz (where one Gigahertz is a billion cycles per second), as reported in the Jan. 14 issue of Physical Review Letters.
A virus’ death knell
All objects have resonant frequencies at which they naturally oscillate. Pluck a guitar string and it will vibrate at a resonant frequency.
But resonating can get out of control. A famous example is the Tacoma Narrows Bridge, which warped and finally collapsed in 1940 due to a wind that rocked the bridge back and forth at one of its resonant frequencies. 
Viruses are susceptible to the same kind of mechanical excitation. An experimental group led by K. T. Tsen from Arizona State University have recently shown that pulses of laser light can induce destructive vibrations in virus shells. 
“The idea is that the time that the pulse is on is about a quarter of a period of a vibration,” Sankey said. “Like pushing a child on a swing from rest, one impulsive push gets the virus shaking.” 
It is difficult to calculate what sort of push will kill a virus, since there can be millions of atoms in its shell structure. A direct computation of each atom’s movements would take several hundred thousand Gigabytes of computer memory, Sankey explained. 

He and Dykeman have found a method to calculate the resonant frequencies with much less memory. 

In practice
The team plans to use their technique to study other, more complicated viruses. However, it is still a long way from using this to neutralize the viruses in infected people.
One challenge is that laser light cannot penetrate the skin very deeply. But Sankey imagines that a patient might be hooked up to a dialysis-like machine that cycles blood through a tube where it can be hit with a laser. Or perhaps, ultrasound can be used instead of lasers. 
These treatments would presumably be safer for patients than many antiviral drugs that can have terrible side-effects. Normal cells should not be affected by the virus-killing lasers or sound waves because they have resonant frequencies much lower than those of viruses, Sankey said. 
Moreover, it is unlikely that viruses will develop resistance to mechanical shaking, as they do to drugs. 
“This is such a new field, and there are so few experiments, that the science has not yet had sufficient time to prove itself,” Sankey said. “We remain hopeful but remain skeptical at the same time.”

Unseen Hazards: from Nanotechnology to Nanotoxicity

11.29.09

Nanotechnology—engineering extremely small particles at the molecular level to create materials with new behaviors and chemical properties— is a powerful new scientific pursuit, one with the potential to produce the next electricity or combustion engine—the next thing to change everything. Unfortunately, the enormous potential of nanotechnology to quell the world’s problems may be offset by its potential harm. The very young field of nanotoxicity has already linked some nanoparticles to:

  • Damage to DNA
  • Disruption of cellular function and production of reactive oxygen species
  • Asbestos-like pathogencity
  • Neurologic problems (such as seizures)
  • Organ damage, including significant lesions on the liver and kidneys
  • Destruction of beneficial bacteria in wastewater treatment systems
  • Stunted root growth in corn, soybeans, carrots, cucumber and cabbage
  • Gill damage, respiratory problems and oxidative stress in fish

Even though these potential threats are widely acknowledged, regulations lag far behind the development and commercialization of products containing nanotechnologies.

The legacy of unregulated chemical and technological commercialization is, in some regards, one of man-made disasters. The track record of asbestos, DDT, PCBs and radiation—substances that were heralded as the technological breakthroughs that would change everything—should serve as a warning that we cannot continue to neglect the potential hazards associated with nanotechnology simply because it is the next big thing.

Detoxifying from Chemtrails. Health. 36 FOODS THAT HELP DETOX AND CLEANSE YOUR ENTIRE BODY

More resources

December 12, 2013

Practiced for thousands of years by cultures around the world –detoxification is about resting, cleansing and nourishing the body from the inside out. By removing and eliminating toxins, then feeding your body with healthy nutrients, detoxifying can help protect you from disease and renew your ability to maintain optimum health. These foods will assist in boosting your metabolism, optimizing digestion, while allowing you to lose weight and fortify your immune system.

1. ARTICHOKES
Artichokes help the liver function at its best, which in turn will help your body purge itself of toxins and other things it doesn’t need to survive. It ups the liver’s production of bile, and since bile helps break down foods which helps your body use the nutrients inside them, an increase in bile production is typically a good thing.
2. APPLES
Apples are full of wonderful nutrients. You get fibre, vitamins, minerals and many beneficial phytochemicals such as D-Glucarate, flavonoids and terpenoids. All of these substances are used in the detox process. One flavonoid, Phlorizidin (phlorizin), is thought to help stimulate bile production which helps with detox as the liver gets rid of some toxins through the bile. Apples are also a good source of the soluble fibre pectin, which can help detox metals and food additives from your body. It’s best to eat only organic apples as the non-organic varieties are among the top 12 foods that have been found to contain the most pesticide residues. Organically produced apples also have a 15 percent higher antioxidant capacity than conventionally produced apples.
3. ALMONDS
Almonds are the best nut source of Vitamin E. In fact, just one ounce contains 7.3 mg of “alpha-tocopherol” vitamin E, the form of the vitamin the body prefers. They’re also high in fiber, calcium, magnesium, and useable protein that helps stabilize blood sugar and remove impurities from the bowels.
4. ASPARAGUS
Not only does asparagus help to detoxify the body, it can help you wage the anti-aging battle, protect you from getting cancer, help your heart to stay healthy, and is a general anti-inflammatory food. It’s also known to help with liver drainage, which might sound like a bad thing, but since the liver is responsible for filtering out the toxic materials in the food and drinks we consume, anything that backs up its drainage is not doing you any favors. Asparagus also helps reduce risk of death from breast cancer and increase the odds of survival.
5. AVOCADOS
This wonder fruit is packed with antioxidants, lowers cholesterol and dilates the blood vessels while blocking artery-destroying toxicity. Avocados contain a nutrient called glutathione, which blocks at least 30 different carcinogens while helping the liver detoxify synthetic chemicals. Researchers at the University of Michigan found that elderly people who had high levels of glutathione were healthier and less likely to suffer from arthritis. Consuming avocados is associated with better diet quality and nutrient intake level, lower intake of added sugars, lower body weight, BMI and waist circumferences, higher “good cholesterol” levels and lower metabolic syndrome risk.
6. BASIL
Basil has anti-bacterial properties, and it’s full of antioxidants to protect the liver. The active ingredients are terpenoids. It is also wonderful for digestion and detoxification, too. It supports the functioning of the kidneys and also acts as a diuretic to help the body expel unwanted toxins. Basil has been known to have anti-ulcer qualities as well as antimicrobial effects that guard against bacteria, yeast, fungi and mold. Basil seed can also help with constipation. The anticancer properties of basil may also relate to its ability to influence viral infections.
7. BEETS
A single serving of beets can do more for your health than most foods in the produce isle. Not only can they boost your energy and lower your blood pressure, but eating beets in the long-term can help you fight cancer, reduce arthritic pain, boost your brain as well as help you lose weight. Beets contain a unique mixture of natural plant chemicals (phytochemicals) and minerals that make them superb fighters of infection, blood purifiers, and liver cleansers. They also help boost the body’s cellular intake of oxygen, making beets excellent overall body cleansers. When you’re detoxing, beets will help by making sure that the toxins you’re getting out actually make it out of your body. Many detox cleanses go wrong when toxins are reintroduced to the body because they don’t make it all the way out.
8. BLUEBERRIES
Blueberries contain natural aspirin that helps lessen the tissue-damaging effects of chronic inflammation, while lessening pain. Just 300 grams of blueberries protects against DNA damage. Blueberries also act as antibiotics by blocking bacteria in the urinary tract, thereby helping to prevent infections. They have antiviral properties and are loaded with super-detoxifying phytonutrients called proanthocyanidins.
9. BRAZIL NUTS
These tasty treats are packed with selenium, which is key to flushing mercury out of your body. The body uses selenium to make ‘selenoproteins’, which work like antioxidants preventing damage to cells and there is growing body of evidence to show it has a key role in our health. The consumption of brazil nuts has been found to be inversely associated with risk of pancreatic cancer, independent of other potential risk factors for pancreatic cancer.
10. BROCCOLI
Broccoli specifically works with the enzymes in your liver to turn toxins into something your body can eliminate easily. If you’re stuck for ways on how to make broccoli taste better try dehydrating or consider eating it raw. But don’t microwave it as this destroys both the nutritional and detox potential. Broccoli contains a very powerful anti-cancer, anti-diabetic and anti-microbial called sulforaphane which helps prevent cancer, diabetes, osteoporosis and allergies.
11. BROCCOLI SPROUTS
Broccoli sprouts can actually provide more benefit than regular broccoli as they contain 20 times more sulfurophane. They contain important phytochemicals that are released when they’re chopped, chewed, fermented, or digested. The substances are released then break down into sulfurophanes, indole-3-carbinol and D-glucarate, which all have a specific effect on detoxification. Add these to your salads and get creative with them in your meals. Researchers have found that an oral preparation made from broccoli sprouts trigger an increase in inflammation-fighting enzymes in the upper airways.
12. CABBAGE
In addition to cleansing your liver, cabbage will also aid in helping you go to the bathroom, which in turn helps you expel the toxins, getting them out of your system so you can start fresh. It contains sulfur, which is essential when it comes to breaking down chemicals and removing them from your body. Along with other cole crops, cabbage is a source of indole-3-carbinol, a chemical that boosts DNA repair in cells and appears to block the growth of cancer cells.
13. CILANTRO
Cilantro, also known as coriander, Chinese parsley or dhania, contains an abundance of antioxidants. Cilantro helps mobilize mercury and other metals out of the tissue so it can attach to it other compounds and allow it to be excreted from the body. It also contains an antibacterial compound called dodecenal, which laboratory tests showed is twice as effective as the commonly used antibiotic drug gentamicin at killing Salmonella.
14. CINNAMON
The oils from cinnamon contain active components called cinnamaldehyde, cinnamyl acetate, and cinnamyl alcohol. Cinnamaldehyde has been well-researched for its effects on blood platelets helps prevent unwanted clumping of blood cells. Cinnamon’s essential oils also qualify it as an “anti-microbial” food, and cinnamon has been studied for its ability to help stop the growth of bacteria as well as fungi, including the commonly problematic yeast Candida. Cinnamon’s antimicrobial properties are so effective that recent research demonstrates this spice can be used as an alternative to traditional food preservatives. It has one of the highest antioxidant values of all foods and its use in medicine treats everything from nausea to menstruation and energy to diabetes.
15. CRANBERRIES
While they are more popular as fruits that help prevent urinary tract infections, cranberries are antibacterial and are known to remove many different toxins from your body. Cranberries feature a rich profile of anti-inflammatory nutrients, provide immune and cardiovascular support, as well as promote digestive health. Consuming cranberry products has been associated with prevention of urinary tract infections (UTIs) for over 100 years.
16. DANDELIONS
Dandelions are considered a powerhouse food full of nutrients that are essential for anyone regularly eating processed foods. Dandelion root (taraxacum officinale) is known to act on the liver and pancreas by straining and filtering toxins & wastes from the bloodstream and its beneficial effects on liver complaints have been well documented by both Asian practitioners and American physicians. They’re a rich source of minerals and provide a variety of phytonutrients. They’re super antioxidants that support cleansing of the digestive tract. Try adding dandelion leaves to your salad.
17. FENNEL
The fennel bulb is high in fiber may also be useful in preventing colon cancer. In addition to its fiber, fennel is a very good source of folate, a B vitamin that is necessary for the conversion of a dangerous molecule called homocysteine into other, benign molecules. The vitamin C found in fennel bulb is directly antimicrobial and is also needed for the proper function of the immune system.
18. FLAXSEEDS
When detoxifying your body, it’s essential to ensure toxins are eliminated properly. Ground flaxseeds provide a wonderful source of fibre that helps to bind and flush toxins from the intestinal tract. They’re also a great source of health promoting omega 3 oils. Try consuming two tablespoons of ground flaxseeds in lemon water every morning. University of Copenhagen researchers report that flax fiber suppresses appetite and helps support weight loss. Men should be cautious when consuming flax as the lignans are similar to the female hormone estrogen as can cause problems for some men.
19. GARLIC
Many detox diets list garlic as a crucial piece of the puzzle. The reason is that garlic boosts the immune system as well as helping out the liver. One good thing about garlic is that you can up your intake without having to worry if your body is going to get used to it or build up a resistance.Sulfur is found in high quantities in garlic — which makes it a good detox food and its antibiotic properties heal your body. Garlic is proven to be 100 times more effective than antibiotics and working in a fraction of the time.
20. GINGER
Along side turmeric, ginger is one of the world’s most potent disease-fighting spices. Ginger spikes your metabolism, flushes out waste, is thought to help liver function, and has some astringent properties. Some detox diets ask you to chew on ginger root. You may also find that adding it to hot water makes the water taste better. Basically any way you can think of it get it into your system is going to be beneficial, especially if you’re suffering from a fatty liver caused by too much alcohol, or too many toxic foods and drinks.
21. GOJI BERRIES
Replace raisins with nutrient-dense Goji berries to boost your vitamin C and beta-carotene intake. Gram for gram, goji berries pack more vitamin C than oranges and more beta-carotene than carrots. Vitamin C can help remove waste from your body, while beta-carotene improves liver performance.
22. GRAPEFRUIT
Grapefruits can prevent weight gain, treat diabetes, lower cholesterol, fight cancer, heal stomach ulcers, reduce gum disease and even keep stroke and metabolic syndrome at bay. Grapefruits can treat disease as well as pharmaceuticals without the side effects. The rich pink and red colors of grapefruit are due to lycopene, a carotenoid phytonutrient. Among the common dietary carotenoids, lycopene has the highest capacity to help fight oxygen free radicals, which are compounds that can damage cells. The big takeaway on grapefruit is that it gets your liver fired up and ready for action, while infusing the rest of your organs with nutrient-laden fruit juice.
23. GREEN TEA
Green tea is often thought of as a great addition to any detox program because of its high antioxidant value. It is the least processed tea and thus provides the most antioxidant polyphenols, notably a catechin called epigallocatechin-3-gallate (EGCG), which is believed to be responsible for most of the health benefits linked to green tea. According to 17 clinical trials, green tea is linked with significantly lower blood sugar.
24. HEMP
Hemp might just be one of nature’s most perfect foods since it is full of antioxidants like Vitamins E and C, as well as chlorophyll which is wonderful for cleansing the body from toxins of all kinds, including heavy metals. The soluble and insoluble fiber in hemp can also keep the digestive tract clean and therefore, reduce the toxic burden on other internal organs. Hemp could free us from oil, prevent deforestation, cure cancer and it’s environmentally friendly.
25. KALE
Kale is now recognized as providing comprehensive support for the body’s detoxification system. New research has shown that the ITCs made from kale’s glucosinolates can help regulate detox at a genetic level. This vegetable is so good for you that it is often recommended to patients that are following a doctor recommended diet when fighting kidney disease. It’s packed with so many antioxidants and has anti-inflammatory properties as well, not to mention all of the vitamins and minerals it contains. Leafy greens are likely the number one food you can eat to regularly help improve your health. They’re filled with fiber along with crucial vitamins, minerals, and plant-based phytochemicals that may help protect you from almost every disease known.
26. LEMONGRASS
This is an herb that is used in Thailand and other parts of the world as a natural way to cleanse several organs at once. It not only helps the liver but also the kidneys, the bladder, and the entire digestive tract. Benefits of using it in your cooking, or drinking it as a tea include a better complexion, better circulation, and better digestion. It is most often used as a tea in the world of detoxing, and there are several recipes you can try until you find one that suits your tastes best.
27. LEMONS
This wonderful fruit stimulates the release of enzymes and helps convert toxins into a water-soluble form that can be easily excreted from the body. In addition, they contain high amounts of vitamin C, a vitamin needed by the body to make glutathione. Glutathione helps ensure that phase 2 liver detoxification keeps pace with phase 1, thereby reducing the likelihood of negative effects from environmental chemicals. Drinking lemon water, which is alkaline-forming, first thing in the morning will help to balance out the acidity of foods we’ve consumed. They also have an incredible effect in detoxing the liver. Fresh lemon juice contains more than 20 anti-cancer compounds and helps balance the body’s pH levels. Here are 45 uses for lemons that will blow your socks off.
28. OLIVE OIL
Some liver cleanses out there call for olive oil mixed with fruit juice in order to trigger your liver to expunge its gallstones. But aside from that olive oil should be your go-to oil when you’re trying to detox the body. That’s because it has a lot of healthy properties, and makes for a better choice of fat than most of your other options. Just be sure not to cook with it at high heat. Use it as a salad dress to help things like dark leafy greens go down. Your best choice is always ice-pressed olive oil, but if you can find a very high quality cold-pressed olive oil, although not as nutritious, it will suffice provided the quality is high and not adulterated.
29. ONIONS
This ubiquitous kitchen staple is as healthy as it is tasty. It’s brimming with sulfur-containing amino acids, which efficiently detox the liver. Raw onions deliver the most health benefits. Even a small amount of “overpeeling” can result in unwanted loss of flavonoids. For example, a red onion can lose about 20% of its quercetin and almost 75% of its anthocyanins if it is “overpeeled”. Onions will soak up arsenic, cadmium, lead, mercury and tin in contaminated foods. The total polyphenol content of onion is not only higher than its fellow allium vegetables, garlic and leeks, but also higher than tomatoes, carrots, and red bell pepper. Onions have been shown to inhibit the activity of macrophages, specialized white blood cells that play a key role in our body’s immune defense system, and one of their defense activities involves the triggering of large-scale inflammatory responses.
30. PARSLEY
Those pretty green leaves don’t just make your plate look great. Parsley boasts plenty of beta-carotene and vitamins A, C and K to protect your kidneys and bladder. Diuretic herbs such as parsley prevent problems such as kidney stones and bladder infections and keep our body’s plumbing running smoothly by causing it to produce more urine. They also relieve bloating during menstruation. The flavonoids in parsley–especially luteolin–have been shown to function as antioxidants that combine with highly reactive oxygen-containing molecules (called oxygen radicals) and help prevent oxygen-based damage to cells. In addition, extracts from parsley have been used in animal studies to help increase the antioxidant capacity of the blood.
31. PINEAPPLES
This tropical delight contains bromelain, a digestive enzyme that helps cleanse your colon and improve digestion. Excessive inflammation, excessive coagulation of the blood, and certain types of tumor growth may all be reduced by bromelain. Two molecules isolated from an extract of crushed pineapple stems have even shown promise in fighting cancer growth.
32. SEAWEED
Seaweed may be the most underrated vegetable in the Western world. Studies at McGill University in Montreal showed that seaweeds bind to radioactive waste in the body so it can be removed. Radioactive waste can find its way into the body through some medical tests or through food that has been grown where water or soil is contaminated. Seaweed also binds to heavy metals to help eliminate them from the body. In addition, it is a powerhouse of minerals and trace minerals. Seaweed extracts can help you lose weight, mostly body fat.
33. SESAME SEEDS
Sesame seeds’ phytosterols have beneficial effects which are so dramatic that they have been extracted from many foods and added to processed foods, such as “butter”-replacement spreads, which are then touted as cholesterol-lowering “foods.” But why settle for an imitation “butter” when Mother Nature’s nuts and seeds are a naturally rich source of phytosterols–and cardio-protective fiber, minerals and healthy fats as well? Sesame seeds contain minerals important in a number of antiinflammatory and antioxidant enzyme systems. Sesame represents one of the top 10 healthiest seeds on Earth.
34. TURMERIC
Curcumin is the active ingredient in the spice turmeric, which gives it its yellow color. The rate at which your detox pathways function depends on your genes, your age, lifestyle and a good supply of nutrients involved in the detox process. Curcumin is used a lot in Ayurvedic Medicine to treat liver and digestive disorders. Turmeric has specifically been studied in relation to the positive effect that it has on the liver. As a high antioxidant spice, turmeric protects the body and prevents disease more effectively than drug based treatments and without the side effects.
35. WATERCRESS
Give your liver a big boost with cleansing action of watercress. If you’re into making smoothies for your detoxing this is a great one to blend up and drink down. This helps to release enzymes in the liver that clean it out and help rid it of toxic buildup. Eating watercress every day helps prevent breast cancer.
36. WHEATGRASS
Wheatgrass restores alkalinity to the blood. The juice’s abundance of alkaline minerals helps reduce over-acidity in the blood and thus also Is a powerful detoxifier, and liver protector. It increases red blood-cell count and lowers blood pressure. It also cleanses the organs and gastrointestinal tract of debris. Wheatgrass stimulates the metabolism and the body’s enzyme systems by enriching the blood. It also aids in reducing blood pressure by dilating the blood pathways throughout the body. Pound for pound, wheatgrass is more than twenty times denser in nutrients than other choice vegetables. Nutritionally, wheatgrass is a complete food that contains 98 of the 102 earth elements.

Large Scale Study Shows Nuts Decrease Cancer Risk By More Than One-Third

Writing in Nature’s British Journal of Cancer, the team behind the new analysis reported that consumption of nuts – including tree nuts such as almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts – was found to be inversely associated with risk of pancreatic cancer, independent of other potential risk factors for pancreatic cancer.
The data, from a large-scale prospective study, investigated the association between nut consumption and risk of pancreatic cancer in more than 75,000 women who took part in the Nurses’ Health Study, and had no previous history of cancer.

“Frequent nut consumption is inversely associated with risk of pancreatic cancer in this large prospective cohort of women, independent of other potential risk factors for pancreatic cancer,” explained the research team – led by Dr Ying Bao of Brigham and Women’s Hospital and Harvard Medical School.The body uses selenium to make “selenoproteins”, which work like antioxidants preventing damage to cells. There is a growing body of evidence to show it has a key role in health. 

Bao and colleagues found that women who consumed a one-ounce serving of nuts two or more times per week had a 35% lower risk of pancreatic cancer when compared to those who largely abstained from nuts.
“This reduction in risk was independent of established or suspected risk factors for pancreatic cancer including age, height, obesity, physical activity, smoking, diabetes and dietary factors,” said Bao.

Soil Degradation A Problem

“Selenium levels in our blood plummeted after the time the government began measuring them in 1974,” says Margaret Rayman, professor of nutritional medicine at the University of Surrey and a leading researcher in selenium’s effects. 

“They stabilised at this sub-optimal level in the mid-Nineties as our diets haven’t changed much since.” 

The problem is compounded by the fact that we import less foods from selenium-rich soils than ever before.

Soil in the U.S. has higher levels of selenium due both to different geological conditions and the fact that it’s generally more alkaline, allowing better uptake of nutrients by plants.
Earlier this year, in a paper published in The Lancet, she detailed selenium’s links to everything from enhanced fertility and thyroid function to preventing plaque build-up in the arteries, regulating blood pressure and reducing cancer risk.
Study Details
Bao and colleagues analysed data from 75,680 women in the Nurses’ Health Study, and examined the association between nut consumption and pancreatic cancer risk. Nut consumption was assessed at baseline and updated every 2 to 4 years.
During the follow up, the team documented 466 incident cases of pancreatic cancer.
After adjusting for age, height, smoking, physical activity, and total energy intake, women who consumed a 28-g (1oz) serving size of nuts twice per week experienced a significantly lower risk of pancreatic cancer, said Bao and colleagues – noting a relative risk of 0.65 compared to those who did not eat nuts.
“The results did not appreciably change after further adjustment for body mass index (BMI) and history of diabetes mellitus,” the team added – noting that the inverse association persisted within strata defined by BMI, physical activity, smoking, and intakes of red meat, fruits, and vegetables.

Consuming Large Amounts of This Mineral Reduces Cancer Risk By 67 Percent


Who would have thought that the earth beneath our feet could be to blame for health woes ranging from heart disease to thyroid problems to cancer? Yet that’s the view of some experts who say levels of selenium, a mineral essential for good health, are so low in soil in Europe that it’s affecting the food chain, diets and, ultimately, the risk of disease.

The body uses selenium to make ‘selenoproteins’, which work like antioxidants preventing damage to cells. 

There is a growing body of evidence to show it has a key role in health. 

Just last week, researchers at the University of East Anglia found people who eat large amounts of the mineral, along with vitamins C and E, are 67 percent less likely to develop pancreatic cancer. 

Previous research has shown that in old age a good selenium intake helps enhance brain function, so that cognition remains sharp and active. 

The problem is we are not getting enough.

The richest food sources of selenium are Brazil nuts, kidney, liver and fish, but the foods that make the largest contribution to our selenium intake — because we eat proportionately more of them — are cereals, bread, meat and poultry. 

However, because levels of selenium in our soil are low, cattle aren’t absorbing as much when they graze, nor are crops or other fresh produce grown on it. 

As a result, there is less selenium available from meat, grains and vegetables.

Farming methods have a part to play. In a study conducted at Warwick University’s Horticultural Research Institute a few years ago, it was found that although British and northern European soils have been relatively low in selenium since the last ice age, levels are being further depleted by intensive modern farming methods and the use of chemical fertilisers. 

‘Selenium levels in our blood plummeted after the time the government began measuring them in 1974,’ says Margaret Rayman, professor of nutritional medicine at the University of Surrey and a leading researcher in selenium’s effects. 

‘They stabilised at this sub-optimal level in the mid-Nineties as our diets haven’t changed much since.’ 

She adds: ‘If you live in the UK, the likelihood is you are not grossly deficient, but do have low levels of selenium.’

The problem is compounded by the fact that we import less wheat from America’s selenium-rich soils than ever before, she says. 

Soil in the U.S. has higher levels of selenium due both to different geological conditions and the fact that it’s generally more alkaline, allowing better uptake of nutrients by plants.

In fact, the average Briton consumes only half (30-35 mcg) of the daily amount recommended by the government (60 mcg for women, 75 mcg for men). 

In the long-term, the effects of low intakes can be devastating, says Professor Rayman.

Earlier this year, in a paper published in The Lancet, she detailed selenium’s links to everything from enhanced fertility and thyroid function to preventing plaque build-up in the arteries and regulating blood pressure.

One study of men with fertility problems showed that 100 mcg selenium supplements taken daily significantly increased sperm cells’ ability to swim, indicating they had been selenium-deficient. 

Eleven percent of men who took the supplement went on to father a child. 

‘Selenium is an essential component of two selenoproteins required for healthy sperm,’ says Professor Rayman.

‘One of these is needed for transportation of selenium into the testes and the other gives sperm a stable structure that allows it to swim.’

But selenium is not without controversy. 

Lately, some of the scientists who once hailed it as a small medical breakthrough for serious diseases have backtracked, suggesting their latest findings appear to show its power may have been overstated. 

Selenium was, for instance, thought to be able to fight prostate cancer and heart disease, but various studies in the past five years have chipped away at the notions.

One large study in the American Journal of Epidemiology followed more than 1,000 adults for seven-and-a-half years and found those who took 200 mcg of selenium daily had no reduction in their risk of developing heart disease or of dying from it than those who took a placebo.

Indeed, eating large quantities of Brazil nuts was found in one study at the University of Warwick to raise cholesterol levels by 10 percent and raise the risk of heart disease, not lower it. 

And while some scientists have recently shown it protects against bladder cancer in women, others have found it does nothing to help to prevent lung cancer.

Similar conflicting evidence surrounds selenium’s role in the prevention of type 2 diabetes, with some studies suggesting high selenium levels lower the prevalence of the condition by helping to control glucose metabolism.

However, other studies, including research by Saverio Stranges, professor of cardiovascular epidemiology at Warwick University, have found no such benefit and, indeed, that it ‘may increase the risk for the disease’.

So what are we to believe? 

Of the negative studies, some — including those on prostate cancer — were conducted on people with already raised levels of selenium who were in no danger of deficiency, Professor Rayman says. In other words, it’s no surprise that giving them a supplement would have no real benefit. 

‘If your selenium status is low to start with, then you will almost certainly benefit from increasing your intake,’ she says. 

‘But if you already have high blood levels of the mineral, you won’t benefit from taking more and it could be dangerous.’ 

Professor Rayman, in her Lancet review, concluded that adding selenium to the diet — either through eating selenium-rich foods or through supplementation — is beneficial only if you really need it. 

So, how do you know if your selenium levels are low and what should you do about it? 

Professor Rayman says: ‘Unless you eat either white or oily fish or offal several times a week, the likelihood is that living in the UK means you aren’t getting enough.’

The best way to boost your intake is eating more fish and other selenium-rich food, but it may also be beneficial to take a supplement.

There is growing debate about whether anyone needs to take single nutrient supplements because of risks of disease — but when it comes to selenium, even sceptics think it’s worth taking. 

After analysing studies for their book The Health Delusion, Aidan Goggins, a pharmacist, and Glen Matten, both of whom have masters degrees in nutritional medicine, found the only antioxidant supplement that appeared to offer protection against cancer was selenium.

However, Professor Rayman warns people should be ‘extremely careful’ about increasing their intake of selenium because too much of it can be dangerous. 

More than 0.45 mg a day can trigger a condition called selenosis, which can cause brittle nails and hair, skin lesions and a garlic-like odour on the breath, adds Claire Williamson, a nutrition scientist at the British Nutrition Foundation. 

Professor Rayman takes a 65 mcg daily supplement and advises popping a pill containing no more than 100 mcg a day of selenium for men and 50-65 mcg for women if your diet contains few selenium-rich foods. 

As selenium tablets often come in much larger doses, you may have to break a tablet in half. 

Professor Rayman warns not to gorge on Brazil nuts. ‘They contain a heavy metal substance called barium in levels that can become toxic, causing nausea and more serious side-effects if you eat them regularly.

‘It’s irresponsible of nutritionists to suggest people should eat Brazil nuts by the handful for this reason.’ No more than two or three nuts a day is recommended. 

Professor Rayman adds: ‘Selenium has many benefits and your body needs to have enough. But more is definitely not better in this case.’
