You may have read about the health benefits of eating more fruits and vegetables. One of the fruits which is very popular all over the world is Apple. Apples are nutritious and filling. They can be eaten any time of the day and in many forms. If you like to eat apples you would be happy to read the information below and if you do not eat apples then you may find it interesting.
According to a recent study, an apple a day may keep obesity away. Researchers at Washington State University say that in particular, the Granny Smith variety of apple could provide a degree of protection from what is considered to be one of the greatest health threats in the United States. The study was led by Giuliana Noratto and the findings were published in the journal Food Chemistry.
The health benefits of derived from eating apples have been known for some time, but previously they have been documented in reference to other types of illness and disease. A 2013 study found that daily apple consumption was as effective as statins at lowering the risk of cardiovascular disease.
Earlier still, a 2011 study demonstrated that the consumption of fruits including apples and pears would lower a person’s risk of having a stroke by more than 50 percent. Until now however, there has been little research conducted to look into the way in which the parts of an apple that are not absorbed during the process of digestion affect the good bacteria in the stomach.
There are certain bioactive compounds in apples which are not absorbed when they are eaten. These include antioxidants such as polyphenols and types of dietary fiber. These compounds have a positive effect on the bacteria in the gut. They have been shown to increase levels of immunity and have a helpful influence on maintaining a healthy body weight.
According to Noratto, from the School of Food Science at Washington State, these bioactive compounds differ dependent on the type of apple that is eaten. The research team looked at seven different types of apple and how these affected the beneficial bacteria in the stomach. Golden Delicious, Granny Smith, Red Delicious, Gala, Fuji, Braeburn and McIntosh apples were analyzed. Of all these, the Granny Smith appeared to have the most positive effect on the bacteria in the gut.
This has implications for obesity, as in obese people the levels of good bacteria in the stomach are often lower than those found in people who have a lower body weight. The researchers used laboratory rats, and when they examined the feces of the rats, they discovered that there was little difference in the presence of different types of good bacteria between the obese mice and the lean mice after eating an apple, whereas before there had been.
This led the researchers to conclude that the difference must be due to the non-digestible dietary fiber and polyphenols present. This may information is useful to those interested in the study of obesity, and foods which can promote beneficial bacteria.
These parts of the apple are able to be chewed in the mouth, exposed to acid in the stomach and the digestive enzymes and still remain unchanged when they enter the colon at the end of the digestive process. In the colon, they are fermented by bacteria present there. This produces butyric acid and it is the butyric acid which is believed to lead to the production of more of the beneficial bacteria in the gut.
Noratto believes that apples in general are a good source of these non-digestible compounds. The researchers have concluded however, that the Granny Smith apple variety has the most beneficial effect. The recent study has suggested that an apple a day may help keep obesity away.
