An apple a day does more than just keep the doctor away, according to a new obesity study.

Researchers found that eating more apples, which contain abundant non-digestible compounds, could help decrease the risk of obesity and disorders associated with it.

"We know that, in general, apples are a good source of these non-digestible compounds but there are differences in varieties," lead researcher Giuliana Noratto, of Washington State University, said in a news release. "Results from this study will help consumers to discriminate between apple varieties that can aid in the fight against obesity."

Previous studies reveal that apples, particularly green Granny Smith apples, help boost beneficial bacteria in the colon. This is because apples contain high amounts of non-digestible compounds, including dietary fiber and polyphenols, and low amounts of carbohydrates.

Researchers found that Granny Smith apples contain more non-digestible compounds than Braeburn, Fuji, Gala, Golden Delicious, McIntosh and Red Delicious apples.

"The nondigestible compounds in the Granny Smith apples actually changed the proportions of fecal bacteria from obese mice to be similar to that of lean mice," Noratto said.

"What determines the balance of bacteria in our colon is the food we consume," added said.

Researchers believe that the latest findings could help prevent conditions associated with obesity like diabetes and heart disease.

The study will be published October in the print edition of the journal Food Chemistry.
