Study reveals red wine ingredient helps body to burn fat

TOO good to be true? Next time you buy a burger, perhaps you should order a side-serve of red wine. It may contain a helpful ingredient for the battle against obesity.

TOO good to be true? Next time you buy a burger, perhaps you should order a side-serve of red wine. It may contain a helpful ingredient for the battle against obesity.

But there’s a catch: Eating fresh grapes and berries produces a much better result when it comes to turning excess flab into calorie-burning “brown” fat, research has shown.

The discovery suggests that diets containing the substance, resveratrol, may help combat obesity.

Scientists gave mice amounts of resveratrol equivalent to humans consuming 340 grams fruit per day.

They found that despite a high-fat diet, the mice gained 40 per cent less weight than animals not fed the compound.

The research showed that the mice were able to change their excess white fat to active “brown” or “beige” fat which reduces weight gain by burning up calories.

Other “polyphenol” chemicals in fruit may have a similar effect, the scientists believe.

Lead researcher Professor Min Du, from Washington State Univesity, US, said: “Polyphenols in fruit, including resveratrol, increase gene expression that enhances the oxidation of dietary fats so the body won’t be overloaded,.

“They convert white fat into beige fat which burns lipids (fats) off as heat, helping to keep the body in balance and prevent obesity and metabolic dysfunction.” He added: “We are using resveratrol as a representative for all the polyphenols.” Blueberries, strawberries, raspberries, grapes and apples are especially rich in the compounds, he said. Three hundred grams amounts to about two or three servings.

Red wines such as merlot or cabinet sauvignon are known to contain resveratrol, but at a fraction of the levels found in grapes, Prof Du pointed out.

“Many of the beneficial polyphenos are insoluble and get filtered out during the wine production process,” he said.

The findings are reported in the International Journal of Obesity.
