CHICAGO -- Antioxidant vitamins, including A, E and C, don't help you live longer, according to an analysis of dozens of studies of these popular supplements. The new review showing no long-life benefit from those vitamins, plus beta carotene and selenium, adds to growing evidence questioning the value of these supplements. Some experts said, however, that it's too early to toss out all vitamin pills - or the possibility that they may have some health benefits. Others said the study supports...

WASHINGTON -- That ice-cold watermelon may be refreshing, but it can be less nutritious than watermelon served at room temperature, U.S. Department of Agriculture scientists reported on Wednesday. Watermelons stored at room temperature deliver more nutrients than refrigerated or freshly picked melons, they reported in the Journal of Agricultural and Food Chemistry. Penelope Perkins-Veazie and Julie Collins of the USDA's South Central Agricultural Research Laboratory in Lane, Oklahoma looked...

By Amy Norton NEW YORK -- People with high blood levels of the nutrient beta-carotene may have better lung function as they age, new research suggests. What's more, the study found, both beta-carotene and vitamin E might offer some lung protection to heavy smokers. Beta-carotene is an antioxidant compound that gives foods such as carrots, sweet potatoes and cantaloupe their orange and yellow coloring; the nutrient is also found in some greens, like spinach and broccoli. The new findings...

NEW YORK (Reuters Health) - A high intake of vitamin E, beta-carotene, and vitamin C does not prevent prostate cancer, results of a large study suggest. However, smokers may have a lower risk of advanced prostate cancer if their intake of vitamin E is high, and men with low dietary beta-carotene intake seem to benefit from supplemental beta-carotene. Previous studies evaluating the associations between antioxidants and prostate cancer risk have yielded contradictory results. So Dr....

50% mixture prevented emphysema in mouse study, Japanese researchers say Tomato juice prevented emphysema in mice exposed to cigarette smoke, a known cause of the lung-destroying disease, Japanese researchers report. They attributed the protective effect to lycopene, an antioxidant with a somewhat checkered history as a supplement to protect against various diseases. The Japanese report, in the February issue of the American Journal of Physiology-Lung Cellular and Molecular Physiology,...

By Andrew Stern CHICAGO (Reuters) - A vitamin-rich diet lowers the risk of contracting macular degeneration, the leading cause of blindness among the elderly in developed countries, researchers said on Tuesday. The antioxidant properties of vitamins C and E, beta carotene and zinc were found to ward off macular degeneration, in which abnormal blood cells grow in the eye and leak blood and fluid that damage the center of the retina and blur central vision. Sufferers are often debilitated and...

Supplement cuts cancer risk in non-smokers, but ups it in those who've smoked, study finds Whether individuals should take a beta-carotene supplement may depend largely on whether they've ever smoked. New research confirms findings from past studies that indicate people who have ever smoked -- which means current and former smokers -- who take beta carotene supplements are at an increased risk of tobacco-related cancers. Conversely, lifetime non-smokers who take beta-carotene supplements...

NEW YORK -- High intake of beta-carotene seems to decrease the risk of tobacco-related cancers among people who've never smoked, but to increase the risk among current or past smokers, new research suggests. Although the findings are based on a study of women, the researchers believe that similar results would be obtained in men. "Based on the findings from our study and others, I would advise against beta-carotene supplements for current or past smokers," senior author Dr. Marie-Christine...

Golden Rice
2013-10-02 14:11:48

Golden Rice is a variety of Oryza sativa rice produced  through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of the rice. The research was conducted with the goal of producing a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A, a deficiency which is estimated to kill 670,000 children under five years old each year. Golden rice is different from its parental strain by the addition of three...
