NIH study provides clarity on supplements for protection against blinding eye disease
(NIH/National Eye Institute) Adding omega-3 fatty acids did not improve a combination of nutritional supplements commonly recommended for treating age-related macular degeneration (AMD), a major cause of vision loss among older Americans, according to a study from NIH. The plant-derived antioxidants lutein and zeaxanthin also had no overall effect on AMD when added to the combination; however, they were safer than the related antioxidant beta-carotene.

After 30 years, is a GM food breakthrough finally here?
Golden rice, a new strain that boosts vitamin A levels and reduces blindness in developing countries, is about to be sown in the Philippines – and is the new battleground cropScientists say they have seen the future of genetically modified foods and have concluded that it is orange or, more precisely, golden. In a few months, golden rice – normal rice that has been genetically modified to provide vitamin A to counter blindness and other diseases in children in the developing world – will be given to farmers in the Philippines for planting in paddy fields.Thirty years after scientists first revealed they had created t...

Consumption Of Colorful Fruit And Vegetables May Prevent Or Delay ALS
New research suggests that increased consumption of foods containing colorful carotenoids, particularly beta-carotene and lutein, may prevent or delay the onset of amyotrophic lateral sclerosis (ALS). The study, published by Wiley in Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, found that diets high in lycopene, beta-cryptoxanthin, and vitamin C did not reduce ALS risk. Carotenoids give fruits and vegetables their bright orange, red, or yellow colors, and are a source of dietary vitamin A... (Source: Health News from Medical News Today)

Could Carrots Reduce Risk Of Type-2 Diabetes?
Stanford University School of Medicine investigators have found that for people harboring a genetic predisposition that is prevalent among Americans, beta carotene, which the body converts to a close cousin of vitamin A, may lower the risk for the most common form of diabetes, while gamma tocopherol, the major form of vitamin E in the American diet, may increase risk for the disease...

A controversial Nobel laureate had stated, in a peer-reviewed paper he described as "among my most important work", that antioxidant supplements "may have caused more cancers than they have prevented".Even the most fad-friendly sections of the UK media were bound to cover the story.In reality, Professor James Watson – one of the DNA double-helix's founding fathers – was only restating what we at Cancer Research UK (alo...

Vitamin supplements may increase risk of death
Vitamin supplements taken by millions of people do not increase life expectancy and may raise the risk of a premature death , according to a review of 67 studies with more than 230,000 subjects.The review, by the Cochrane Collaboration which regularly pools data from trials to evaluate drugs and treatments, found supplements vitamin A, vitamin E and beta-carotene are detrimental to health. In 47 trials with 180,938 people and a low risk of bias, the "antioxidant supplements significantly increased mortality", the authors wrote. When the antioxidants were assessed separately and low risk of bias trials were included and sel...

Antioxidants Role in Chronic Disease Prevention Still Uncertain - Huge Doses Considered Risky
Insufficient evidence exists to support claims that taking megadoses of dietary antioxidants, such as selenium and vitamins C and E, or carotenoids, including beta-carotene, can prevent chronic diseases, says the latest report on Dietary Reference Intakes (DRIs) from the Institute of Medicine of the National Academies.
