Washington: A new study has found that a major ingredient in those green coffee bean dietary supplements - often touted as "miracle" weight-loss products - doesn`t prevent weight gain in obese laboratory mice fed a high-fat diet when given at higher doses. The first-of-its-kind study also linked the ingredient to an unhealthy build-up of fat in the liver.Vance Matthews, Kevin Croft and their team noted that coffee is rich in healthful, natural, plant-based polyphenol substances. They cited evidence from past studies that coffee drinkers have a lower risk of obesity, high blood pressure, type 2 diabetes and other disorders collectively termed the "metabolic syndrome."
