Their findings, published in the Journal of Experimental Medicine, suggest a potential new way to treat some serious infections, the researchers said. Gold-colored strains of Staphylococcus aureus bacteria, which get their color from antioxidant compounds called carotenoids,...

Experts disagree about the finding's validity, however HealthDay News -- Leafy greens, whole grains, nuts and other foods rich in vitamin E may help prevent Parkinson's disease, according to a new review of eight studies. The researchers stressed that the finding needs to be verified in clinical trials before vitamin E could be recommended as a means of warding off the condition, however. Parkinson's is a neurodegenerative disease characterized by a progressive deterioration of motor control....

TUESDAY, Nov. 30 (HealthDayNews) -- Twenty years ago, high doses of beta carotene were thought to have cancer-preventing power, and two large clinical trials were launched to determine if it might reduce lung cancer among cigarette smokers. But the disease-fighting properties of beta carotene, a carotenoid which the body converts into vitamin A, fell far short, the studies found. One trial was even halted before its scheduled end because of the adverse effects of high doses of beta carotene...

A U.S. study of smokers taking beta-carotene supplements found cardiovascular disease mortality disappeared after the smokers stopped taking the supplements. However, the risk of lung cancer may persist, especially in females and former smokers, according to the study published in the Wednesday issue of the Journal of the National Cancer Institute. During the 1980s, preliminary studies suggested beta-carotene might help prevent lung cancer in smokers. But two trials were halted when the...

EXPANDED ABSTRACT KEY WORDS: * antioxidants * prooxidants * dietary fat Prooxidants often are considered synonymous with reactive species, toxic substances that can cause oxidative damage to major constituents of biological systems. In contradistinction, antioxidants are defined as any substance that, when present at low concentrations compared with that of the oxidizable substrate, significantly prevents the prooxidant-initiated oxidation of that substrate. In this context, and based on...

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...
