Blueberry Juice May Help with Weight Management
Modified blueberry juice may help decrease food intake, blood glucose levels and body weight, according to a study published in the August 18, 2009 issue of the International Journal of Obesity.
Researchers from the University of Montreal in Canada gave the modified blueberry juice to mice prone to obesity, insulin resistance, diabetes and hypertension. These mice were specifically chosen because of their molecular resemblance to humans who suffer from obesity and obesity-linked type 2 diabetes.
After 3 days of consuming the blueberry juice, the food intake and body weights of the mice decreased. In addition, the mice saw a 35% reduction in glycemia levels.
The blueberry juice used in the study was transformed through fermentation to increase the fruit's antioxidant effects. The researchers believe the higher antioxidant levels led to an increase in the levels of adiponectin in the mice's bodies.
Adiponectin is a hormone that plays a role in the prevention of type 2 diabetes, obesity and atherosclerosis. As a persons body fat percentage increases, their adiponectin levels drop, making them more vulnerable to obesity and diabetes.
The researchers next step is to identify the active compounds in the transformed blueberry juice. They believe these compounds could be used to create supplements that could help combat obesity and diabetes.
Blueberries are a rich source of potent antioxidants called polyphenols. Previous studies have shown blueberries to have a number of positive health effects, including cholesterol reduction, reduction in vision loss and prevention of some cancers and neurodegenerative diseases such as Alzheimer's.
A good way to incorporate more blueberries into your diet is by adding them to pancakes or adding them to fruit smoothies.
