    Reuters ^ | Jan. 29, 2014 | Sharon Begley
    (Reuters) - A decades-old medical mystery - why antioxidants such as vitamin E and beta carotene seemed to accelerate the growth of early lung tumors in high-risk populations such as smokers, rather than protect them from cancer, as theory suggests - may have been solved, according to research published on Wednesday. In essence, "antioxidants allow cancer cells to escape cells' own defense system" against tumors,... That lets existing tumors, even those too small to be detected, proliferate uncontrollably. .... The antioxidants caused a 2.8-fold increase in lung tumors, made the tumors more invasive and aggressive, and caused the mice to...

    It sounds like the ingredient list for an indulgent dessert. But red wine, chocolate and strawberries are more than a guilty pleasure. They could all help guard against diabetes. A study found for the first time the high content of flavonoids found in berry fruits may regulate blood glucose levels, and stave off type 2 diabetes. Flavonoids are antioxidant compounds found in plants, as well as tea, red wine and chocolate, which can protect against a wide range of diseases, including heart disease, hypertension, some cancers and dementia. The study found the main protective effect came from higher intakes of...

    Athens, Ga. - A new University of Georgia study has found that select varieties of sorghum bran have greater antioxidant and anti-inflammatory properties than well-known foods such as blueberries and pomegranates. Researchers measured polyphenolic compounds, which naturally occur in plants to help fight against pests and disease, and found that the black and sumac varieties of sorghum have significant levels of antioxidants. Many fruits also contain these compounds, they said, though sorghum bran may prove to be the richest and cheapest source. “Since most human chronic disease states are associated with chronic inflammation and high oxidative stress, a food ingredient...

    "I'm president of the United States, and I'm not going to eat any more broccoli!" proclaimed George H.W. Bush in a 1990 news conference. America's 41st president disdained broccoli so much that he banned the vegetable from the White House menu. Now 84, Bush may live to regret his broccoli bullying: New scientific evidence suggests that a chemical in broccoli may rejuvenate the immune system enough to ward off common diseases of aging. At the University of California- Los Angeles, Andre Nel and colleagues recently discovered that sulforaphane, a phytonutrient in broccoli, activates antioxidant pathways at the cellular level.

Spanish researchers found that after four weeks of drinking two glasses of wine per day, women showed lower levels of certain inflammatory substances in their blood. The findings, reported in the American Journal of Clinical Nutrition, suggest a mechanism by which wine -- particularly red wine -- may protect the heart. Numerous studies have found that wine drinkers tend to have lower rates of heart...

The new research, published in the journal Cancer Cell, supported the general notion that vitamin C and other so-called antioxidants can slow tumor growth, but pointed to a mechanism different from the one many experts had suspected. The researchers generated encouraging results when giving vitamin C to mice that had been implanted with human cancer cells -- either the blood cancer lymphoma or prostate cancer. Another antioxidant, N-acetylcysteine, also limited tumor growth in the mice, the...

Researchers found that eating spaghetti covered in sauce made from these orange tomatoes, called Tangerine tomatoes, caused a noticeable boost in this form of lycopene in participants' blood.

    Children with autism have a abnormal metabolic profile that may play a role in the condition, according to researchers at the University of Arkansas. The researchers believe autistic children are more vulnerable to oxidative stress, which occurs when the antioxidant system fails to counteract the production or exposure to free radicals. These free radicals then damage cells in the brain, as well as the gastrointestinal tract, and the immune system, which they believe may contribute to the the neurological, gastrointestinal and immunologic pathology that occurs in autistic children. The team analyzed and compared blood samples from 95 autistic children with...

New research also suggests that some of the environmental chemicals that have gotten into many of our foods -- through the...
