Drink Soda? Take 12,000 Steps

Gretchen Reynolds on the science of fitness.People who consume the sweetener fructose — which is most people nowadays — risk developing a variety of health problems. But the risk drops substantially if those people get up and move around, even if they don’t formally exercise, two new studies found.

Most of us have heard that ingesting fructose, usually in the form of high-fructose corn syrup, is unhealthy, which few experts would dispute. High-fructose corn syrup is used to sweeten many processed foods and nearly all soft drinks.

The problem with the sweetener is that, unlike sucrose, the formal name for common table sugar, fructose is metabolized primarily in the liver. There, much of the fructose is transformed into fatty acids, some of which remain in the liver, marbling that organ and contributing to nonalcoholic fatty liver disease.

The rest of the fatty acids migrate into the bloodstream, causing metabolic havoc. Past animal and human studies have linked the intake of even moderate amounts of fructose with dangerous gyrations in blood sugar levels, escalating insulin resistance, Type 2 diabetes, added fat around the middle, obesity, poor cholesterol profiles and other metabolic disruptions.
