Tuesday, Sep 1st, 2009 ↓Antioxidants Not Associated With Increased Melanoma Risk →
Sept 1. 2009 (Sciencedaily.com)—Antioxidant supplements do not appear to be associated with an increased risk of melanoma, according to a new report.
A recent randomized trial of antioxidants for cancer prevention found that daily supplementation with nutritionally appropriate doses of vitamins C and E, beta carotene, selenium and zinc appeared to increase the risk of melanoma in women four-fold, according to background information in the article. Because an estimated 48 percent to 55 percent of U.S. adults use vitamin or mineral supplements regularly, the potential harmful effects of these nutrients is alarming, the authors note.
Maryam M. Asgari, M.D., M.P.H., of Kaiser Permanente Northern California, Oakland, and colleagues examined the association between antioxidants and melanoma among 69,671 women and men who were participating in the Vitamins and Lifestyle (VITAL) study, designed to examine supplement use and cancer risk. At the beginning of the study, between 2000 and 2002, participants completed a 24-page questionnaire about lifestyle factors, health history, diet, supplement use and other cancer risk factors.
Intake of multivitamins and supplements during the previous 10 years, including selenium and beta carotene, was not associated with melanoma risk in either women or men. The researchers also examined the risk of melanoma associated with long-term use of supplemental beta carotene and selenium at doses comparable to the previous study and found no association.
“Consistent with the present results, case-control studies examining serologic [blood] levels of beta carotene, vitamin E and selenium did not find any association with subsequent risk of melanoma,” the authors write. “Moreover, the Nurses’ Health Study reported no association between intake of vitamins A, C and E and melanoma risk in 162,000 women during more than 1.6 million person-years of follow-up.”

Eat Fat With Tomatoes to Absorb All the Nutrients →
Aug 24, 2009 (Mercola.com)—Tomatoes are a good source of the antioxidants lycopene and beta-carotene. But if you eat a tomato without adding a little fat, your body is unlikely to absorb all these nutrients.
Scientists recruited graduate students to eat bowls of salad greens with tomatoes and various types of salad dressings. The researchers put IV lines into the participants’ veins and drew blood samples before and after they’d eaten the salads in order to get precise measurements of the absorption of nutrients.
When researchers went back and analyzed the blood samples, they realized that people who had eaten fat-free or low-fat dressings didn’t absorb the beneficial carotenoids from the salad. Only when they had eaten the oil-based dressing did they get the nutrients.

Resveratrol - The Miracle Nutrient for Cancer, Cholesterol and Longevity by Mike Adams the Health Ranger →
Aug 12, 2009 (NaturalNews.com) —You’ve all heard the good news about resveratrol, commonly known as the “red wine nutrient.” There’s more to resveratrol than red wine, though, and it’s helpful for far more than just preventing heart disease. It’s also phenomenal for maintaining a healthy cholesterol balance and even supporting increased longevity.
As you’ll see below in quotes from health experts about resveratrol, this “miracle” nutrient is also useful for preventing many types of cancer. As you read these quotes, pay special attention to any mention of phytoalexins, as this is a class of plant-based nutrients that you’ll be hearing about much more in the future (as nutritional healing becomes more widely known).
If you want to acquire some resveratrol, there are lots of natural sources such as red wine or grape leaves (the leaves actually contain far more than the grapes themselves). The Chinese medicine herb hu zhang is also loaded with resveratrol.

How High Carbohydrate Foods Can Raise Risk For Heart Problems →
June 27, 2009 (Sciencedaily.com)—Doctors have known for decades that too much carbohydrate-laden foods like white bread and corn flakes can be detrimental to cardiac health. In a landmark study, new research from Tel Aviv University now shows exactly how these high carb foods increase the risk for heart problems.
“Looking inside” the arteries of students eating a variety of foods, Dr. Michael Shechter of Tel Aviv University’s Sackler School of Medicine and the Heart Institute of Sheba Medical Center — with collaboration of the Endocrinology Institute — visualized exactly what happens inside the body when the wrong foods for a healthy heart are eaten. He found that foods with a high glycemic index distended brachial arteries for several hours.
Elasticity of arteries anywhere in the body can be a measure of heart health. But when aggravated over time, a sudden expansion of the artery wall can cause a number of negative health effects, including reduced elasticity, which can cause heart disease or sudden death.

Low Vitamin D May Be Root Cause of Cancer →
June 15, 2009 (NaturalNews.com)— What initially causes cancer to develop? The current scientific model assumes that a genetic mutation begins the genesis of a malignancy. But what if that assumption is wrong and there’s another key to the start of cancer?
Scientists at the Moores Cancer Center at the University of California (UC) in San Diego have raised that possibility. And they’ve come up with another, brand new model of how cancer develops. Reporting online in the current Annals of Epidemiology, they point to a host of research that suggests cancer develops when cells lose the ability to stick together in a healthy, normal way — and the key factor to this initial triggering of a malignancy could well be a lack of vitamin D.

Chlorophyll in Wheatgrass Proven to Fight Cancer →
June 10, 2009 (NaturalNews.com)— Wheatgrass is an amazingly nutrient dense food. Dr. Earp-Thomas once said that, “15 pounds of wheatgrass is the equivalent of 350 pounds of carrots, lettuce, celery and so forth.” Wheatgrass contains no less than thirteen vitamins and all 20 essential amino acids. It also contains chlorophyll which has some proven health and anti-cancer properties.
A prominent researcher on wheatgrass, Dr. Thelma Arthur has done research showing that the consumption of wheatgrass juice can help in detoxifying the blood and strengthening the immune system. Chlorophyll plays a key role in detoxifying the liver which is where the blood is purified.

CoQ10 may cut pre-eclampsia in high-risk women →
By Stephen Daniells, 01-Apr-2009 (FoodNavigator.com)
Supplements of coenzyme Q10 (CoQ10) may reduce the risk of developing pre-eclampsia in women at risk for the condition, suggests a new study from Ecuador.
Women receiving 200 mg of CoQ10 a day had a 10 per cent lower risk of developing pre-eclampsia than women on placebo, according to results of the randomised, double-blind, placebo-controlled trial.
Researchers from the Central University of Ecuador and the Hospital Gineco Obstetrico Isidro Ayora report their findings in the International Journal of Gynecology & Obstetrics.
Key Nutrients Help Maintain Brain Function throughout Lifetime →
Feb 16 09 (NaturalNews) If you want to stay mentally sharp all your life, new research shows the time to intervene is now. Alzheimer’s disease and dementia have complex causes that involve nutritional neglect as well as genetic risk factors and predisposition. Genetic risk factors for cognitive decline may remain dormant and never get switched on unless deficiencies in key nutrients are present. This suggests that nutritional status throughout the lifetime determines cognitive outcome. This is very good news because it means that people willing to make good nutrition a priority may not need to experience cognitive decline and the diseases that go with it.
Study spotlights key nutrients needed to prevent brain damage and improve performance
The importance of early nutritional intervention and prevention of deficits in critical brain nutrients was the finding of researchers at the Center for Cellular Neurobiology and Neurodegenerative Research at the University of Massachusetts. Their study, reported in the January edition of Nutrition Research, hypothesized that a combination of nutritional additives may be able to provide neuro-protection.

JAMA Anti-Vitamins Studies Flawed →
(NaturalNews) Scientific research isn’t as simple as portrayed in movies or fiction – and the results certainly are rarely as simple as what is reported by the mainstream (and, too often, lazy) media. A case in point: the news that two studies just published in the December 9 edition of the Journal of the American Medical Association (JAMA) “prove” vitamins C and E do nothing to prevent heart disease or cancer, and selenium and vitamin E are also worthless against prostate cancer.
At first glance, the results of these studies are clearly disappointing and surprising. After all, there is other research indicating vitamins E and C and selenium have a positive impact on health based on animal and laboratory studies.
So what did the JAMA studies really show?

New Study Shows Niacin-Bound Chromium Benefits Diabetics →
Nov 11 08 (NaturalNews) Nicacin-bound chromium (Cr-N) provides significantly more heart health benefits than chromium picolinate (Cr-P), the form more commonly found in supplements, according to a study presented at the 68th Annual Scientific Session of the American Diabetes Association.
Researchers fed three groups of obese, diabetic rats the same diet, supplemented with Cr-N, Cr-P, or nothing at all for eight weeks. They rated the animals’ cardiovascular health by measuring cholesterol and triglyceride levels, as well as the levels of certain markers of inflammation, such as tumor necrosis factor-alpha (TNF-alpha), monocyte chemoattractant protein 1 (MCP-1) and C-reactive protein (CRP).

Coenzyme Q10 helpful at reversing damage from aging →
Sep 18 2008 (Mercola) — You probably know that I normally don’t promote many supplements. I believe supplements should complement your healthy diet and never serve as a replacement.
There’s simply no substitute for eating healthy unprocessed whole foods.
However, there are a few supplements I consider highly beneficial for nearly all adults. One of these is Coenzyme Q10 (CoQ10).
