Blueberries may limit fat formation

Many people have heard that ingredients found in blueberries are good for one's heart. Now, a new study conducted by researchers at Texas Woman's University indicates that the fruits may be good for a person's weight loss plan, too.

The scientists explained that polyphenols found in blueberries and other plants are natural chemicals with fat-fighting capabilities. They play a dual function, in which the polyphenols block the formation of new fat cells and promote the breakdown of lipids.

Using adipose tissue samples from mice, the researchers tested how varied doses affected the development of new cells that allow fat to be stored. The results showed that administering smaller amounts of blueberry polyphenols reduced the amount of lipids in the tissues by 27 percent, while higher doses yielded decreases of up to 73 percent.

"We still need to test this dose in humans to make sure there are no adverse effects and to see if the doses are as effective. This is a burgeoning area of research. Determining the best dose for humans will be important," lead investigator Shiwani Moghe said.
