Apples might be holding the secret to dealing with obesity. A study showed that the apple variety Granny Smith contains certain compounds that affect the gut microflora that in turn has effects on weight maintenance: apples could be the answer to obesity in this regard.
The expression “an apple a day keeps the doctor away” might be more true than one would have thought. Many studies have shown that apples have a variety of health benefits, including preventing vascular mortality, reducing the risk of having strokes, and so on. Lately, a new research suggested that the bioactive compounds found in apples might be affecting the gut’s flora in a favourable way such that it might be a way of fighting obesity.
The research focused on particular varieties of apples: the Granny Smith, Braeburn, Fuji, Gala, Golden Delicious, McIntosh and Red Delicious. The variety to be observed to have the most beneficial impact on the gut bacteria was the Granny Smith.
The gut bacteria are associated with digestion, immunity and weight maintenance. That is how obese people have disbalanced gut bacteria. The chemical components of the Granny Smiths interacted with these gut bacteria, thereby demonstrating how apples can potentially impact positively on obesity.
While the balance of gut bacteria of obese people is supposed to be impaired, the study showed that the faeces of obese mice which consumed Granny Smiths had similar proportion of bacteria as the faeces of lean mice.
Granny Smiths are rich in dietary fiber which is not digested, together with polyphenols while they are low in carbohydrates. The bioactive compounds contained in apples, such as polyphenols and dietary fiber, are not absorbed in the body cells during digestion. Rather, they stay and affect the gut flora of microorganisms. These compounds are fermented by the bacteria found in the colon, thereby producing butyric acid that causes the gut bacteria to flourish.
Imbalance of the gut microflora also predisposes people to diabetes: the imbalance caused by the food we eat leads to chronic inflammation that, in turn, leads to diabetes. The researchers found that Granny Smiths might help to reduce the inflammation associated with these diseases.
The authors are positive that the results will enable consumers to use apples to fight obesity.
