    01.05.2004· In agreement with previous data from Taylor and Richardson (1980), heat treatment of milk was associated with an increase in its antioxidant activity. Such an increase was detected over different time frames depending on the heating temperature. In fact, it can be observed that samples heated at 120°C showed a steep and progressive increase in antioxidant activity. By contrast, in the case of

    Disease Prevention by AntioxidantsDisease Treatment with AntioxidantsDetrimental Effects of Antioxidant SupplementsReferencesFurther ReadingThere are several antioxidant systems within the body that help cope with the oxidative stress that results from regular metabolic processes. Antioxidants in diet can also cancel out the cell-damaging effects of free radicals. These antioxidant supplements act in addition to the endogenous systems and their lack can cause several ill-consequences of oxidative stress. There is evidence that some types of vegetables and fruits protect against a number of cancers and other diseases. Large studies have shown that peop

    Free radicals are highly unstable molecules that are naturally formed when you exercise and when your body converts food into energy. Your body can also be exposed to free radicals from a variety of environmental sources, such as cigarette smoke, air pollution, and sunlight. Free radicals can cause “oxidative stress,” a process that can trigger cell damage. Oxidative stress is thought to
