An APPLE A DAY WOULD KEEP OBESITY AWAY !!
An apple a day could help to keep the doctor away, at least as far as obesity is concerned, according to a new study.
Scientists
at Washington State University have found that non-digestible compounds
in apples – specifically, Granny Smith apples - may help prevent
disorders associated with obesity.
The study is thought to be the first to assess these compounds in apple cultivars grown in the Pacific Northwest.
"We
know that, in general, apples are a good source of these nondigestible
compounds but there are differences in varieties," said food scientist
Giuliana Noratto, the study's lead researcher.
"Results
from this study will help consumers to discriminate between apple
varieties that can aid in the fight against obesity," said Noratto.
The
tart green Granny Smith apples benefit the growth of friendly bacteria
in the colon due to their high content of non-digestible compounds,
including dietary fibre and polyphenols, and low content of available
carbohydrates.
Despite
being subjected to chewing, stomach acid and digestive enzymes, these
compounds remain intact when they reach the colon. Once there, they are
fermented by bacteria in the colon, which benefits the growth of
friendly bacteria in the gut.
The
study showed that Granny Smith apples surpass Braeburn, Fuji, Gala,
Golden Delicious, McIntosh and Red Delicious in the amount of
nondigestible compounds they contain.
"The
nondigestible compounds in the Granny Smith apples actually changed the
proportions of fecal bacteria from obese mice to be similar to that of
lean mice," Noratto said.
The
discovery could help prevent some of the disorders associated with
obesity such as low-grade, chronic inflammation that can lead to
diabetes.
The
balance of bacterial communities in the colon of obese people is
disturbed. This results in microbial byproducts that lead to
inflammation and influence metabolic disorders associated with obesity,
Noratto said.
"What determines the balance of bacteria in our colon is the food we consume," she said.
The study appears in the journal Food Chemistry.
