Antioxidant supplements do not appear to increase risk of melanoma, as previously suspected, according to a new report. Findings in a recent randomized trial of antioxidants for cancer prevention seemed to suggest daily supplementation with nutritionally appropriate doses of vitamins C and E, beta-carotene, selenium and zinc increased the risk of melanoma in women four-fold. Because an estimated 48 to 55 percent of U.S. adults use vitamin or mineral supplements regularly, the potential for...

Strigolactones are plant hormones, which were first discovered in crop plants during the infection with the parasitic plant "Striga". Only plants which produce strigolactones were infected with the parasite resulting in a significant reduction of vigor. Moreover, this signaling pathway plays also an important role in plants to initiate symbiotic interactions with mycorrhiza fungi to enhance the absorption of nutrients from the soil. The third hormonal effect known so far is an influence on...

TORRANCE, Calif., June 29 /PRNewswire/ -- Studies have determined certain nutrients have positive effects on eye health. The research focus is on Vitamins C and E, found in high levels in the eye lens; lutein and zeaxanthin, which are concentrated in the retina; and beta-carotene (which converts to Vitamin A), another strong antioxidant. Major studies, like the Blue Mountains Eye Study and the Age-Related Eye Disease Study, have shown positive results in preventing eye problems. The Blue...

Many breast cancer patients undergoing treatment continue to take antioxidants, even though the consequences of taking the supplements remain unknown, a new study found. Six in 10 women reported using antioxidants while receiving chemotherapy, radiation or hormone therapy for breast cancer, and about seven in 10 antioxidant users said they used high doses, which was defined as higher than the dose contained in a Centrum multivitamin. Antioxidant supplements include vitamin C, vitamin E,...

The beta-carotene in so-called "Golden Rice" converts to vitamin A in humans, according to researchers at Baylor College of Medicine and Tufts University in an article that appears in the current issue of the American Journal of Clinical Nutrition. Golden Rice was developed in the early 1990s with a grant from the Rockefeller Foundation with the goal of creating rice that had beta-carotene -- a vitamin A precursor "“ in the rice grain. In its current form, Golden Rice contains 35...

A genetic breakthrough has allowed the engineering of multiple vitamins into a single plant for the first time, in hopes of granting a nutritive boost in the diet of developing countries. Though genetic engineering has previously been used to enhance vitamin content in a variety of crops such as rice, potatoes, lettuce and tomatoes, this will mark the first time that scientists have been able to intensify multiple vitamins in a single plant. European scientists have genetically modified (GM)...

A diet high in vegetables can reduce the risk of prostate cancer, researchers in China suggest. Ruth Chan of The Chinese University of Hong Kong and colleagues examined more than 100 studies and concluded that the primary mechanism of this positive vegetable effect is antioxidant protection against DNA and cell damage. The researchers said tomatoes and their byproducts contain the carotenoid antioxidant lycopene. Overall, studies for tomatoes and lycopenes show inconsistent results on...

Vitamin supplements can prevent hearing loss in laboratory animals, University of Florida researchers said. The supplements used in the research are composed of antioxidants -- beta carotene and vitamins C and E -- and the mineral magnesium, senior author Colleen Le Prell of the University of Florida said. When administered prior to exposure to loud noise, the supplements prevented both temporary and permanent hearing loss in test animals, the study said. What is appealing about this...

TORRANCE, Calif., Feb. 18 /PRNewswire/ -- According to a new study conducted by Francine Grodstein, Sc.D., of Brigham and Women's Hospital (BWH) and Harvard Medical School, Boston, men who take Beta-Carotene supplements for 15 years or longer may have less cognitive decline. Two groups of men, long-term users and short, supplemented with 50 milligrams of Beta-Carotene every other day. Long-term participants were treated for an average of 18 years and the short-term participants for an...

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...
