Artificial sweeteners have been considered as an alternative to reduce the consumption of sugar, especially in people who suffer from diabetes and obesity. But recent studies show the opposite effect.
According to Israeli researchers, the chemicals contained in artificial sweeteners may disrupt the body's metabolism and increase blood sugar. This happens because the sweetener interactions with bacteria in the gut.
However, it does not mean eating regular sugar is healthier than artificial sugars. "Sugar can made a bad effect on some people," said Dr. Eran Elinav, researchers from the Weizmann Institute of Science, Israel.
The study initially tested mice. They add artificial sweeteners to drinking water rats, whether saccharin, sucralose, or aspartame. As a result, these animals had higher blood sugar than regular sugar water, or water without sugar.
The researchers found that the artificial sweeteners such as changing the function of rat intestinal bacteria. When they give antibiotics to fight the bacteria, the blood sugar levels of the mice to be the same again.
Then proceed to the 400 human studies. The results are not much different from studies in mice. Blood sugar of people who were given artificial sweeteners were also higher than those eating regular sugar.
The composition of the bacterial
There are trillions of bacteria that live in the intestines of a person. Bacteria are often called mikrobioma is important to maintain normal bowel function. Changes in the composition of these bacteria would affect several body functions. For example, previous studies found that the composition of the balance of bacteria in the gut will affect a person's risk of obesity or diabetes.
However, the composition of the bacteria in one's body can be different from other people. It also has an effect on how their body responds to food diasup.
In Elinav study, the examiners added saccharin in the diet of seven people who are not used to consume artificial sweeteners. In just four days, their blood sugar to rise and the composition of their gut bacteria instantly changed.
"What is surprising and interesting is the fact that the ability of a person receiving artificial sweeteners can be predicted even before they eat," said Eran Segal, computational biologist at the Weizmann Institute of Science.
The reason why changes in gut bacteria can increase blood sugar remains unclear. But artificial sweetener allegedly could be made into a bacterial extract more fat, causing obesity.
So, should we avoid artificial sweeteners? Previous studies also showed positive benefits of this low-calorie sugar. For example, to prevent obesity.
Some research is being conducted to ascertain the effects of artificial sweeteners on the body. Recent research is also a discussion of scientists, physicians, and the public.
"We are not ready to recommend the use of artificial sweeteners and recommended dosage, even after this study," said Segal. "We only present the results of studies in humans and mice. Research has not concluded the benefits of artificial sweeteners either," he said ..
