Fat issues

20 new hormones and other substances not previously known to be secreted into the blood by human fat cells have been discovered by scientists in The Netherlands. The proteomics research suggests that excess fat tissue is not the dormant storage it was once thought to be and instead plays an active role in sending out chemical signals to other parts of the body that might increase the risk of heart disease, diabetes and cancer. The research adds to considerably to the short list of hormones, including appetite-controlling leptin, that were previously known to science.
