Daily dose of sugary drinks pose risk of non-alcoholic fatty liver disease

Making a habit of drinking sugar sweetened drinks on a daily basis can prove harmful for liver, as a new study claims that it increases the risk for non-alcoholic fatty liver disease (NAFLD).

Tufts University (USA) researchers analysed 2,634 self-reported dietary questionnaires from mostly Caucasian middle-aged men and women enrolled in the National Heart Lunch and Blood Institute (NHLBI) Framingham Heart Study's Offspring and Third Generation cohorts.

The sugar-sweetened beverages on the questionnaires included caffeinated- and caffeine-free colas, other carbonated beverages with sugar, fruit punches, lemonade or other non-carbonated fruit drinks. The participants underwent a computed tomography (CT) scan to measure the amount of fat in the liver and the authors of the current study used a previously defined cut-point to identify NAFLD. They saw a higher prevalence of NAFLD among people who reported drinking more than one sugar-sweetened beverage per day compared to people who said they drank no sugar-sweetened beverages. 
The relationships between sugar-sweetened beverages and NAFLD persisted after the authors accounted for age, sex, body mass index (BMI), and dietary and lifestyle factors such as calorie intake, alcohol, and smoking. In contrast, after accounting for these factors the authors found no association between diet cola and NAFLD.

Sugar-sweetened beverages are a major dietary source of fructose, the sugar that is suspected of increasing risk of NAFLD because of how our bodies process it.

The study was published in the Journal of Hepatology. The study added to a growing body of research suggesting that sugar-sweetened beverages may be linked to NAFLD and other
