Get thinner with the right kind of apple

If you bob for apples this Halloween, you may be able to offset some of the fattening effects of holiday candy: A study of how apples feed the probiotic bacteria in the intestines shows that one apple variety may be particularly helpful in helping you keep your weight down.

One of the health problems that arises when you gain weight is an increase in the body’s inflammation. The extra fat you carry around your middle as you put on pounds leads the immune system to overproduce cells that can interfere with the function of various organs. The result is a greater susceptibility to chronic illnesses like heart disease and diabetes.

But Granny Smith apples, lab tests at Washing State University indicate, may help limit this inflammation and, at the same time, help eliminate some of those extra pounds. The dietary fiber and other natural substances (“nondigestible compounds”) in Granny Smiths are particularly adept at nourishing the digestive tract’s probiotic bacteria that keep digestion functioning smoothly.

Apples contain lots of fiber and nutrients to improve your health.“We know that, in general, apples are a good source of these nondigestible compounds but there are differences in varieties,” says researcher Giuliana Noratto, a food scientist. “Results from this study will help consumers to discriminate between apple varieties that can aid in the fight against obesity.”

Granny Smiths are a concentrated source of the natural substances preferred by probiotic bacteria. They are also lower in sugar which can might otherwise promote the growth of harmful microbes.

Noratto believes that the apples can support the growth of probiotic bacteria associated with less body fat. She notes that the bacterial communities living in the digestive tract of overweight people can be dominated by harmful bacteria.

“What determines the balance of bacteria in our colon is the food we consume,” she said.
