Fructose expands gut surface

A study feeding mice high-fructose corn syrup has found it increases the gut’s surface area that is associated with enhanced absorption of dietary nutrients and weight gain.

High-fructose corn syrup is a widely used sweetener in human diets and excess consumption of processed sugars, and high-fructose corn syrup is strongly implicated in diet-induced obesity. Obesity predisposes people to various diseases and conditions

Whether and how fructose causes obesity in humans remains a hotly debated question2,3. In a report in Nature that should make one think twice before gulping down sugar-sweetened drinks with fatty snacks, Taylor et al.4 propose that HFCS promotes obesity by boosting the ability of the intestine to absorb nutrients.
