The Role of Selenium in Cellular Health and Cancer Prevention


By Dr. Mercola

Micronutrients are incredibly important and vital to your health, but are you getting enough, and perhaps even more importantly, the right form? Mark Whitacre, Ph.D., is a leading expert on one of the most important micronutrients, selenium.

Selenium is a trace element a Swedish chemist, Baron Jöns Jacob Berzelius, discovered almost 200 years ago. Today, modern scientists recognize it as an essential mineral for human health, with potent anti-inflammatory, antiviral and anti-cancer activity.

There are fewer than 100 selenium Ph.D. biochemists in the world. Whitacre received his master’s degree in nutrition at Ohio State University in Columbus, Ohio, in the late 1970s — a time when selenium was quickly becoming a hot topic.

“After I finished my master’s degree at Ohio State, I went to Cornell University to get my Ph.D. in nutritional biochemistry and to study under Gerald F. Combs Jr.[,Ph.D., who] was probably the leading authority in selenium research, and probably still is,” Whitacre says.

During his Ph.D. research at Cornell in selenium biochemistry, Whitacre researched the biochemical role of selenium in pancreatic cells. At the time, researchers were just starting to discover the biological necessities for selenium.

Brazil Nuts are Best Source of Cancer Fighting Selenium

KONICA MINOLTA DIGITAL CAMERA
Rich, creamy Brazil nuts are the best source of selenium, the mineral that works with zinc to prevent breast cancer.  A recent study at the University of Otago in New Zealand found that eating just two Brazil nuts a day is as effective in increasing selenium and boosting glutathione as taking a selenium supplement. And eating Brazil nuts brings many other benefits not found in selenium supplements.Researchers investigated the ability of Brazil nuts to increase selenium compared to that of selenomethionine, believed to be the preferred supplement because of its high bioavailability. A randomized controlled trial was conducted with 59 New Zealand adults. Participants consumed two Brazil nuts daily, a selenomethionine supplement, or a placebo. Plasma selenium and plasma and whole blood glutathione levels were measured at baseline and at intervals following treatment. Changes in plasma selenium and glutathione activity in the Brazil nut and selenomethionine groups differed significantly from the placebo group but not from each other. The change in whole blood glutathione activity was greater in the Brazil nut group than in both the placebo and selenomethionine groups. (more…)

3 Minerals Your Skin is Craving

3 Minerals your skin is craving and you could very well be deficient in!

The importance of minerals in skincare has been severely overlooked, especially in comparison to the attention vitamins receive. 

Minerals are essentially the “spark plugs” of the body, carrying out important bodily functions through enzyme reactions. They facilitate the transfer of nutrients across cell membranes with important assistance from vitamins.

In addition, they maintain PH balance and proper nerve conduction, contract and relax muscles, provide structural support, and regulate tissue growth. As you can see, minerals are a must to maintaining a healthy functioning body, but also to maintain healthy vibrant skin. (more…)

Avoiding Serious Complications from Viral Infections

As soon as flu vaccinations start next month, some people
getting them will drop dead of heart attacks or strokes, some
children will have seizures and some pregnant women will miscarry.
New York Times 2009

Don’t want to die/suffer from one of these viral infections medical authorities are again scaring the world with? If so stay away from doctors and their flu vaccines. Vaccines are finally getting the bad rap they deserve and it’s not just coming from parents who have seen their kids devastated when doctors and nurses attack their children with as many as nine vaccines at a time but now the British Medical Journal is firing all its guns at the reprehensible vaccine industry[1] that no one in their right mind should trust. What sane person would trust a doctor, nurse or medical official who endorses injecting babies with mercury? (more…)

Selenium Medicine E-Book Launch

Selenium Medicine E-Book Cover

On Christmas Eve of last year (2012) I received a telephone call from someone I will always remember as a selenium angel. Because of him I wrote this book Selenium Medicine and started experimenting on myself by self-administering startling high dosages of a special type of selenium.

This is an important book because selenium figures in so strongly to the cancer story as the latest large population-based cohort study from The Netherlands suggests. This is not the first time that scientists are telling us that selenium may protect against advanced prostate cancer. (more…)

Five ways to strengthen your immunity using simple food choices

The best way to avoid developing colds, influenza, and other viral diseases this winter is not to go out and get more vaccines and over-the-counter drugs. Your immune system is fully equipped to thwart these conditions naturally on its own, provided you feed it the nutrients it needs in order to maintain homeostasis. Here are five ways to strengthen your immune system naturally using simple food choices:

1) Garlic. This powerful member of the onion family comes up frequently in lists of food and herbs that promote health and prevent disease, and for good reason. Garlic’s high allicin content is largely responsible for its disease-fighting effects, as this powerful antioxidant compound neutralizes free radicals and quells disease-causing inflammation. As a whole, garlic has been used for thousands of years to prevent and treat respiratory, bacterial, fungal, viral, and parasitic infections as well. (more…)
