Green tea confirmed as a weight loss nutrient and heart health antioxidant



Green tea (and its less refined cousin, white tea) has been a part of the ancient Chinese tradition for countless generations, in large part due to its rich endowment of bioactive catechins. Many studies over the past decade have shown that green tea is a powerful tool to improve metabolism in a way that is supportive of weight loss.

Scientists publishing in the Journal of Agricultural Food Chemistry demonstrate that it activates genes associated with fat burning while also helping to reduce absorption of fat from the digestive tract. Further evidence on the gene-altering activity of green tea is reported in the International Journal of Cardiology, as polyphenols from the drink lower free radical damage to help maintain telomere length in heart cells. Drinking several cups of green tea each day may hold the key to effective weight management and cardiac health.

Researchers from the Departments of Chemical Biology and Pharmacology and Toxicology at Rutgers University in New Jersey examined the effect of green tea supplementation on obese mice, known to exhibit similar metabolic characteristics to humans. The animals were broken into two groups and both were fed a traditional high fat/Western style diet. One group received water supplemented with the green tea bioactive catechin EGCG, while the second group acted as a non-supplemented control.
