There may be a lot of truth to the idea that an apple a day may keep the doctor way. Washington State University reported on Sept. 29, 2014 an apple a day could keep obesity away. Washington State University scientists have come to the conclusion that nondigestible compounds which are in apples, specifically, Granny Smith apples, may actually help in preventing disorders which are associated with obesity.
Food scientist Giuliana Noratto, who was the study’s lead researcher, has said we know in general that apples are a good source of health promoting nondigestible compounds. However, there are many differences in varieties. Noratto and fellow researchers therefore decided to investigate which varieties of apples can assist in the fight against obesity. It was determined that tart green Granny Smith apples have a particularly powerful beneficial effect on the growth of friendly bacteria in the colon because of their high content of non-digestible compounds.
Tart green Granny Smith apples also have a good supply of dietary fiber and polyphenols and are low in content of available carbohydrates. These compounds remain intact when they reach the colon in spite of being subjected to chewing, stomach acid and digestive enzymes. Fermentation in the colon of these compounds benefits the growth of friendly bacteria in the gut. It was shown in this study that Granny Smith apples surpass other types of apples in the amount of nondigestible compounds which they contain.
The findings from this research could help prevent some of the disorders which are associated with obesity such as low-grade, chronic inflammation which can lead to diabetes. In obese people the balance of bacterial communities in the colon is disturbed. The resulting microbial byproducts can lead to inflammation and can influence metabolic disorders which are associated with obesity.
This study has been published in the journal Food Chemistry. Noratto has said the food we consume determines the balance of bacteria found in our colon. By re-establishing a healthy balance of bacteria present in the colon metabolic processes which have an influence on inflammation and the sensation of feeling satisfied are stabilized. It is suggested by the results of this study that non-digestible compounds in apples might potentially help to re-establish a disturbed microbiota balance which is seen in obesity. Therefore an apple a day may really be exceptionally good for your health.
