A new University of Michigan Cardiovascular Center study suggests that blueberries may help reduce belly fat and risk factors for cardiovascular disease and metabolic syndrome.

The magic bullet is the high level of phytochemicals in blueberries. Dark purple fruits are high in the phytochemical anthocyanin.

So far, we know that the fruit works on rats, which were the test subjects. A blueberry-enriched powder was mixed into the rats' diet, which was either low-fat or high-fat rat chow. After 90 days, the rats with the blueberry-enriched diet had less abdominal fat, lower triglycerides, lower cholesterol and improved fasting glucose and insulin sensitivity.

And their health was even better when combined with the low-fat diet. That group had lower body weight, lower total fat mass and reduced liver mass than the rats on the high-fat diet. An enlarged liver is linked to obesity and insulin resistance, a hallmark of diabetes. According to Science Daily:

“Some measurements were changed by blueberry even if the rats were on a high fat diet,” says E. Mitchell Seymour, M.S., lead researcher and manager of the UM Cardioprotection Research Laboratory. “We found by looking at fat muscle tissue, that blueberry intake affected genes related to fat-burning and storage. Looking at muscle tissue, we saw altered genes related to glucose uptake.” 

The study was supported by the U.S. Highbush Blueberry Council, which also supplied the blueberry powder. The council did not play a role in the study’s conduct or analysis.
