Forget Red Delicious, Fuji and Gala. Scientists at Washington State University have found that chowing down on Granny Smith apples may help prevent disorders associated with obesity.
Unlike other varieties, Granny Smith apples have a high content of non-digestible compounds such as dietary fiber and polyphenols. These compounds remain intact when they reach the colon, even after passing through stomach acid and digestive enzymes. Here, the compounds are fermented by bacteria in the colon, which stimulates the growth of friendly bacteria in the gut.
In the study, which appears in October’s print edition of the journal Food Chemistry, consumption of the nondigestible compounds in Granny Smith apples changed the fecal bacteria proportions of obese mice to resemble that of lean mice. The balance of bacterial communities in obese individuals’ colons is disturbed, but re-establishing a healthy balance can stabilize metabolic processes linked to the feeling of fullness or satiety. What this means is we can maintain a healthy balance of bacteria in our colon by the food we consume, namely Granny Smith apples.
This discovery could help prevent low grade, chronic inflammation that may lead to diabetes. So, here’s another reason to finally go apple picking—aside from your girlfriend.
