If you eat one apple every day, you will protect yourself from obesity , especially if the variety is Granny Smith, according to a new study.
Previous analyzes show that apples have different health benefits. Consumption of one apple a day can be as effective for cardiovascular health as daily use of statins.
According to the experts in the present study, very few studies focus on bioactive compounds in apples that fail to be absorbed during digestion . Such are polyphenols and dietary fiber. They affect the "good" bacteria, which strengthen the immune system and also help maintain a healthy weight .
The researchers note that there are few studies focusing on how the effects of these bioactive compounds vary in different varieties of apples .
During a laboratory study, they analyzed how bioactive compounds from seven different varieties of apples affect intestinal bacteria . Experts find that compared to other varieties, Granny Smith have the most beneficial effects on these bacteria.
People who are obese usually have an imbalance.
Scientists explain that Granny Smith apples are high in insoluble dietary fiber and polyphenols , while low in carbohydrates. Even after chewing and exposure to digestive enzymes and stomach acids, the compounds reach the colon unscathed.
The bacteria that are there then lead to the fermentation of the compounds by producing butyric acid, which stimulates the growth of "good" intestinal bacteria.
The data from the study are published in the journal Food Chemistry .
