Fructose linked to weight gain

2 June 2015

A new study has suggested that a key component in fruit and vegetables could be contributing to weight gain.

Fructose, a simple carbohydrate derived from fruit and vegetables, is often found in many soft drinks and processed baked goods. New research at the Beckman Institute for Advanced Science and Technology at the University of Illinois found that fructose can cause significant weight gain, compared to simple sugar glucose.

Published in the journal Scientific Reports, the report draws new insight on a link that has remained unclear for a long time - sugar intake and the rising obesity crisis.

Catarina Rendeiro, a postdoctoral research affiliate at the Beckman Institute for Advanced Science and Technology and lead author on the study, said: "The reality is that people are not only consuming more fructose through their diets, but also consuming more calories in general."

The researchers found that even with the recommended calorie intake fructose was found to be causing increased body weight, liver mass, and fat mass in comparison to eating glucose.

They say the study suggests that such levels of fructose can indeed play a role in weight gain, favour fat deposition, and also contribute to physical inactivity. Given the dramatic increase in obesity among young people and the severe negative effects that this can have on health throughout one's life, it is important to consider what foods are providing our calories."
