Jan. 23, 2008 -- The benefits of green tea might include blocking fat and keeping extra pounds at bay, according to preliminary lab tests in mice.
Don't skip over that word "preliminary." There's no proof yet that sipping green tea will do the same for people. Staying in shape continues to be a balancing act between calories and activity.

A healthy liver isn't fatty. But obesity -- in mice or in people -- can lead to fatty buildup in the liver and cause nonalcoholic fatty liver disease.

The University of Connecticut's Richard Bruno, PhD, RD, and colleagues report their findings in February's edition of The Journal of Nutrition.
