When our cells process the oxygen we breathe and the food we eat every day in order to survive, they generate potentially toxic by-products popularly known as "free radicals". Some of these molecules perform functions essential to the organism, but if there are too many of them the cells' internal structures can be damaged, preventing the cells from functioning properly and potentially leading to chronic disease. This process is called oxidative stress.Our bodies contain a veritable arsenal of antioxidant enzymes that help maintain an appropriate reactive oxygen species balance, but these control mechanisms become less efficient as we get older. According to an article published in the journal Nutrition, supplementing one's diet with the amino acid taurine could be a viable nutritional strategy to combat the problem.The study described in the article was conducted at the University of São Paulo (USP) in Brazil and involved 24 women volunteers aged between 55 and 70. They were randomly divided into two groups. One group took three 500 mg capsules of taurine per day for 16 weeks (1.5 g per day). The other took capsules containing only corn starch (placebo). Neither the participants nor the researchers knew which group each volunteer belonged to.Markers of oxidative stress were analyzed in blood samples collected before and at the end of the intervention. One of the most interesting results was an increase of almost 20% in levels of the antioxidant enzyme superoxide dismutase (SOD) in the group that received taurine, compared with a decrease of 3.5% in the control group. As the authors explain, SOD protects cells against harmful reactions of the superoxide radical."Preventing the buildup of free radicals that naturally occurs with aging probably prevents cardiovascular disease, diabetes and high blood pressure, among other chronic conditions," said Ellen de Freitas, a professor at the Ribeirão Preto School of Physical Education and Sports (EEFERP-USP) and co-principal investigator for a project supported by FAPESP.According to Freitas, very few studies of the effects of taurine in the context of aging…
