Could Eating an Apple Prevent Obesity?

Non-digestible compounds found in apples—namely, granny smith apples—could prevent obesity-related disorders, according to a recent study.

For the study, researchers evaluated the impact of bioactive compounds (including polyphenols and dietary fiber that are not absorbed for digestion) on the good gut bacteria of obese mice using 7 different apple varieties: granny smith, fuji, gala, golden delicious, mcIntosh, red delicious, and braeburn.

The study showed that, while gut bacteria in obese individuals is typically unbalanced, when researchers compared the feces of obese mice consuming granny smith apples to the feces of lean mice, the bacteria proportions were similar.

Investigators suggested that the discovery could help healthcare providers prevent obesity-related disorders including low-grade, chronic inflammation which could lead to diabetes.

The complete study is published in the October issue of Food Chemistry.
