Nutrition in the news this week... And a few warnings as well...

Highlights in todays blog include new research that shows why it is not a good idea to have frequent CT Scans, even though they may be recommended by your doctor. Why I do not recommend using sun screens and use vitamin D and antioxidants instead. Also, more good news on Resveratrol, Curcumin, Magnesium, Black Cohosh , Alpha lipoic acid and L-acetyl-Carnitine, and of coarse, exercise. And, last but not least, a video on Anti-Cancer Foods you should consume.



CT Scans Causing Cancer in Patients, Many Scans Medically Unjustified...
A surge in the use of CT scans in the last 25 years has led to millions of patients per year being unnecessarily exposed to dangerous radiation that increases their risk of cancer, according to a paper published in the New England Journal of Medicine."It has been estimated that about 0.4 percent of all cancers in the United States may be attributable to the radiation from CT studies," the authors wrote. Because cancer can take a decade to appear, "this estimate might now be in the range of 1.5 to 2.0 percent" when adjusted for the current level of CT use.

Exercise May Prevent Brain Shrinkage In Early Alzheimer's Disease...
Mild Alzheimer's disease patients with higher physical fitness had larger brains compared to mild Alzheimer's patients with lower physical fitness, according to a study published in the July 15, 2008, issue of Neurology®, the medical journal of the American Academy of Neurology.

Popular Fish, Tilapia, Contains Potentially Dangerous Fatty Acid Combination...
Farm-raised tilapia, one of the most highly consumed fish in America, has very low levels of beneficial omega-3 fatty acids and, perhaps worse, very high levels of omega-6 fatty acids, according to new research from Wake Forest University School of Medicine.

Resveratrol and Curcumin Protect Against Neurodegenerative Diseases...
Modern medicine has verified the therapeutic value of curcumin, particularly as an anti-inflammatory agent with strong antioxidant properties. This makes it potentially useful in neurodegenerative diseases, in which both oxidative stress and inflammation play important roles. Curcumin acts as a neuroprotectant, shielding the brain’s neurons from some of the damage for which such diseases are notorious. Among the numerous specific actions that have been observed (in laboratory cell cultures) are the inhibition of amyloid-beta and the induction of heme oxygenase-1, an enzyme that protects against oxidative stress. Also, “Resveratrol is an efficient protective molecule against MPTP-induced brain lesions and may serve as a comple-mentary and/or preventive therapy in neurodegenerative diseases.“

Magnesium: Widespread Deficiency with Deadly Consequences...
“Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure, and is known to be involved in energy metabolism and protein synthesis. There is an increased interest in the role of magnesium in preventing and managing disorders such as hypertension, cardiovascular disease, and diabetes.”

CDC Finds 97 Percent of Americans Contaminated by Sunscreens ...
The Center for Disease Control (CDC) released a new study showing that nearly all Americans are contaminated with oxybenzone, a widely-used sunscreen ingredient. This chemical so far has been linked to allergies, hormone disruption, and cell damage, as well as low birth weight in baby girls whose mothers are exposed during pregnancy. Oxybenzone is also a penetration enhancer, a chemical that helps other chemicals penetrate the skin. So where has the FDA been on this?

Black Cohosh Herb Halts Growth of Breast Cancer Tumors ...
Extract of black cohosh may halt the growth of breast cancer cells, according to a new study conducted by the French company Naturex and published in the journal "Phytomedicine." The study was funded by the National Institutes of Health and the Susan G. Komen Breast Cancer Foundation.

Video - Two Anti-Aging Pills Worth Asking Your Doctor About...
New studies in rats suggest that two over-the-counter supplements, alpha lipoic acid and L-acetyl-carnitine delay cellular aging and promote greater longevity. If they work in rats, they just might work in humans too.

Resveratrol Has Anti-aging and Anti-Cancer Properties, Linked to Cardiovascular Health ...
A wealth of new research findings continue to underscore the wonders of resveratrol, the compound discovered only a few years ago that has already achieved superstar status. Found predominately in red wine, grapes and peanuts, resveratrol is now showing to significantly impact the aging process, regulate for positive cardiovascular function, and protect against and reverse cancer.

High-Fat, High-Carb Meals Cause More Oxidative Stress in Obese People ...
Meals high in fat and carbohydrates produce damaging changes inside the body that are more long-lasting in the obese, according to a study conducted by researchers from Kaleida Health in Buffalo, N.Y., and published in the Journal of Clinical Endocrinology & Metabolism.Researchers fed eight obese participants and 10 participants of normal weight a 1,800-calorie meal consisting of a Big Mac, a large order of French fries, a large Coke and an apple pie. Sixty-two percent of the calories in the meal came from carbohydrates, 30 percent came from fat and 8 percent came from protein. For all participants, it was the first meal they had eaten that day, and they were given only 15 minutes to finish it.

Floss Your Teeth -- On The Double...
In dental offices all over the world, patients are often told they are not flossing enough or instructed to floss more. As the old saying goes, you only need to floss the teeth you want to keep. After all, not flossing regularly can lead to tooth decay and to periodontal disease, the leading cause of tooth loss in adults.
