Some of the mice were fed a normal diet of “mouse chow” , containing 10 percent fat. The rest were fed a diet of 60 percent fat – the sort of unhealthy diet that would pile excess pounds on a human frame.
Over a 10-week trial, the high-fat-fed mice developed fatty liver and diabetic symptoms – the same metabolic consequences we see in many over-weight, sedentary people, Shay said.
But the chubby mice that received the extracts accumulated less fat in their livers, and they had lower blood sugar, than those that consumed the high-fat diet alone.
Ellagic acid proved to be a powerhouse in this experiment, too, lowering the high-fat-fed mice’s blood sugar to nearly the levels of the lean, normally-fed mice.
