Multiple nutritional studies have demonstrated that blueberries exert a powerful cardioprotective effect due to the high concentration of polyphenols they contain. But can they also help with weight loss?
Researchers from the Texas Woman’s University (TWU) examined the role this amazing fruit plays in the initial development of fat cells that could have a significant impact on weight reduction efforts and obesity. They found that blueberries inhibit the creation of new fat cells by altering lipid metabolism. Therefore, a daily dose of fresh blueberries may hold the key to natural weight loss.
Researchers at TWU set out to evaluate whether blueberries play a role in the development and differentiation of new baby fat cells, or adipocytes, which are the primary vehicle for fat storage in the body. In the past, studies have shown powerful natural polyphenols found in plants inhibit the formation of fat cells and induce lipolysis, which is the breakdown of fats from cellular storage.
The study used different concentrations of a wild blueberry extract performed on tissue cultures to determine the effect on fat cell initiation. The blueberry polyphenols showed a dose-dependent suppression of fat cell differentiation. Fat cells exposed to the highest polyphenol concentration showed a 73 percent decrease in lipid breakdown. And cells exposed to the lowest blueberry concentration exhibited a 27 percent decrease in lipids.
Blueberries Boost Release of Lipids From Existing Fat Cells
The lead study author,Shiwani Moghe,MS, determined that blueberry polyphenols can inhibit a critical path leading to obesity at the molecular level and may play a significant role in blocking the development of new fat cells. The berry may also play a part in releasing fat from adipocytes that will help millions with the desire to lose weight.
As she noted, “This is a burgeoning area of research. Determining the best dose for humans will be important. The promise is there for blueberries to help reduce adipose tissue from forming in the body.”
But the power of the blueberry doesn’t end there…
Blueberry Polyphenols Prevent Arterial Hardening
Polyphenols from blueberries have been shown to be effective in the fight against arterial hardening or atherosclerosis. Researchers writing in the Journal of Nutrition found that regular blueberry consumption can help prevent harmful plaques and lesions from increasing in size in coronary arteries. A diet containing blueberries for 20 weeks was shown to reduce arterial plaque lesions from 39 percent to 58 percent, dramatically lowering risk for a deadly heart attack.
Blueberries provide a tasty source of plant polyphenols that help prevent coronary artery disease and can assist with weight loss efforts. Add 4 to 8 ounces of fresh blueberries to your diet each day or take an organically produced, concentrated extract supplement to naturally improve health and prevent fat cell development.
