An Apple a Day, Will Make the Doctors Go Broke.

OMG... almost 2 months of travel for presentations and tradeshows, and now finally back to getting some new studies on this blog!

...and since the last study posted, I got my new iPhone 6. But this post isn't about Apple and my new phone. No. It's about the real apples--the kind you can eat.

In this new study, researchers found that nondigestible compounds found in a variety of apples may help prevent disorders associated with obesity. While this was only an in vitro and mice study, I'm sharing this because I believe it's got potential to show the same in humans.

The researchers characterised the levels of certain compounds in Braeburn, Fuji, Gala, Golden Delicious, Granny Smith, McIntosh and Red Delicious varieties. They found the tart green Granny Smith apples benefited the growth of friendly bacteria in the colon due to their high content of non-digestible compounds, including dietary fiber and polyphenols, and low content of available carbohydrates.

Although subjected to chewing, stomach acid and digestive enzymes, these compounds will remain intact when they reach the colon, where they will be fermented by colonic bacteria. This in turn benefits the growth of friendly bacteria in the gut, and actually changed the proportions of fecal bacteria from obese mice to be similar to that of lean mice.

The food we eat is partially responsible for the balance of bacteria we find in our intestines. We already know that the intestinal microbiome of obese people is disturbed. This results in microbial byproducts that lead to low-grade, chronic inflammation and influence metabolic disorders associated with obesity, like diabetes and sensation of satiety (fullness).

Most reason to go apple picking next fall!
