The Ganepão conference considers, within its educational proposal, the dissemination of knowledge as a fundamental action. On this space, you can follow relevant nutrition contents based on scientific evidence.
A study published in the American Journal of Clinical Nutrition indicates a possible association between intake of sugar-sweetened beverages and obesity, moreover this association may be modified by a genetic predisposition to obesity.
Conducted by researchers at the Research Unit for Dietary Studies at the Parker Institute and Institute of Preventive Medicine in Denmark, the study assessed 4765 individuals. It was studied the interactions between genetic predisposition to obesity and soda consumption in relation to the annual variation in body weight, BMI, waist circumference (WC) and waist-hip ratio adjusted for BMI (WHR). The model for the assessment of genetic predisposition was built based on 50 single nucleotide polymorphisms associated with obesity, considering all these variables.
There was a significant mean increase of 0.07 kg / year each refrigerant portion ingested per day. “A genetic predisposition may strengthen the association between soft drink intake and BW”, the authors conclude.
