Blueberry intake included in hypocaloric diet decreases weight, glucose, cholesterol, triglycerides and adenosine levels in obese subjects

Obesity is a disease characterized by an excessive accumulation of fat in the body and it has been linked the enhancement of inflammation-related endogenous molecules, such as adenosine (AD). Since blueberries may induce anti-obesity effects, we tested the hypothesis that blueberries consumption contained in hypocaloric diet would decrease weight, BMI as well as glucose, cholesterol, triglycerides and AD levels in obese subjects. The baseline conditions of obesity-related variables were collected for all subjects prior the implementation of blueberries intake. Later, participants received a hypocaloric diet that included the consumption of blueberries (50 g/day) during 30 days. We found that male obese subjects that consumed blueberries showed a decrease in weight, glucose, cholesterol, triglycerides and AD whereas female obese subjects that ate blueberries in hypocaloric diet showed no differences in weight, BMI, glucose and triglycerides but displayed a diminution in cholesterol and AD levels. Data suggest that intake of blueberries seems to decrease some of the obese-linked parameters in male or female subjects. Importantly, blueberry consumption decreased the inflammation-related compound AD in both sexes.
