The study reveals the flavor or monosodium glutamate (MSG can also increase the waist. The researchers found that people who eat MSG are more likely to be overweight or obese.
The relationship between MSG intake and overweight high after the researchers calculated the number of calories people eat. Ka He, a nutrition scientist at the University of North Carolina, Chapel Hill, who led the study, said that although the risk of weight gain caused by MSG are the implications for public health is great.
“All the people who are overweight consume MSG,” he said as quoted by Reuters.
MSG is one of the most widely used additives in foods. Although it tends to be more popular in Asian countries, the MSG was also used in America. In Uncle Sam’s country is MSG found in processed foods, like canned soup.
Daily intake of MSG in the U.S. estimated that only about half a gram. While Japan and Korea is estimated to average consumption of MSG 10 grams per day.
Although MSG is considered safe, some people complain of headaches, nausea and other adverse reactions.
Several studies have examined the potential link between MSG and weight, with conflicting results. Scientists have speculated that people can eat large portions of food with MSG because it just tastes better. Other evidence suggests that MSG may interfere with signals in the body system that regulates appetite.
In a recent study, published in the American Journal of Clinical Nutrition, the researchers measured the direct intake of MSG. Found, men and women who ate MSG average of 5 grams per day is about 30 percent more likely to become overweight. When compared to those who eat little that is less than one-half gram of the day found they did not include people who are overweight.
How exactly the relationship between MSG and weight? Is possible to do with the hormone leptin, which regulate appetite and metabolism. Found that people who consume more MSG produces more leptin.
“Consumption of MSG can cause leptin resistance, so the body does not get the energy it receives from food. So why do people who eat MSG has gained weight regardless of how many calories they consume.
This opinion is still debated. Ivan E. de Araujo, a neurobiologist at Yale University who has studied the effects of MSG to leptin, is not convinced by the new findings.
Leptin is released by fat cells, so the weight of people that they have more leptin in their blood, said Araujo. MSG’s impact on the level of leptin, then, just may be a reflection of the growing body mass.
