Study reveals a direct correlation between fat browning and consumption of flavan 3-ols

In cold conditions, brown adipose tissue (BAT) or brown fat generates heat to keep the body warm. Compared with white adipose tissue, BAT has more mitochondria-;subcellular organelles associated with energy production-;which allows it to burn calories and produce heat by activating the mitochondrial uncoupling protein 1 (Ucp-1).

Study uncovers a class of microbial enzymes that drive ulcerative colitis

Ulcerative colitis, a subtype of inflammatory bowel disease, is a chronic ailment of the colon affecting nearly one million individuals in the United States. It is thought to be linked to disruptions in the gut microbiome -; the bacteria and other microbes that live inside us -; but no existing treatments actually target these microorganisms.
