University of Pretoria (UP) researchers have found that the antioxidant content of certain types of tea can be likened to that found in recommended portions of fruit and vegetables.
Half a cup of black tea, oolong tea or green tea contained the same amount of antioxidants with radical scavenging capabilities (RSC) as that of a 200mg vitamin C tablet.
Researchers at the University of Pretoria (UP) may have identified the gene that is responsible for diet-related obesity. By exploring the role of the novel gene Slc7a8, they have made a potential breakthrough in current knowledge about the cellular mechanisms that drive fat accumulation. This understanding is crucial in developing effective treatments.
