【科普】食用味精容易使人发胖
ScienceDaily (Aug. 14, 2008) — People who use monosodium glutamate, or MSG, as a flavor enhancer in their food are more likely than people who don't use it to be overweight or obese even though they have the same amount of physical activity and total calorie intake, according to a University of North Carolina at Chapel Hill School of Public Health study published this month in the journal Obesity.
Researchers at UNC and in China studied more than 750 Chinese men and women, aged between 40 and 59, in three rural villages in north and south China. The majority of study participants prepared their meals at home without commercially processed foods. About 82 percent of the participants used MSG in their food. Those users were divided into three groups, based on the amount of MSG they used. The third who used the most MSG were nearly three times more likely to be overweight than non-users.
"Animal studies have indicated for years that MSG might be associated with weight gain," said Ka He, M.D., assistant professor of nutrition and epidemiology at the UNC School of Public Health. "Ours is the first study to show a link between MSG use and weight in humans."
Because MSG is used as a flavor enhancer in many processed foods, studying its potential effect on humans has been difficult. He and his colleagues chose study participants living in rural Chinese villages because they used very little commercially processed food, but many regularly used MSG in food preparation.
"We found that prevalence of overweight was significantly higher in MSG users than in non-users," He said. "We saw this risk even when we controlled for physical activity, total calorie intake and other possible explanations for the difference in body mass. The positive associations between MSG intake and overweight were consistent with data from animal studies."
As the percentage of overweight and obese people around the world continues to increase, He said, finding clues to the cause could be very important.
"The U.S. Food and Drug Administration and other health organizations around the world have concluded that MSG is safe," He said, "but the question remains – is it healthy?"
Co-authors on the study included Liancheng Zhao and colleagues from Fu Wai Hospital and Cardiovascular Institute at the Chinese Academy of Medical Sciences in Beijing. Other researchers on this study were from Northwestern University in Chicago and the INTERMAP Cooperative Research Group.

ScienceDaily (Aug. 14, 2008) — People who use monosodium glutamate, or MSG, as a flavor enhancer in their food are more likely than people who don't use it to be overweight or obese even though they have the same amount of physical activity and total calorie intake, according to a University of North Carolina at Chapel Hill School of Public Health study published this month in the journal Obesity.
科学日报（2008年8月14日）报道——据北卡罗林娜大学小礼拜堂山学院公共卫生研究所本月在《肥胖》杂志所发表的研究表明，在食物中使用谷氨酸钠（MSG）作为增味剂的人们比不食用它们的人们更加容易产生超重或是肥胖，即使是在双方都有同等程度的体力活动和总热量摄入的情况下依然如此。
Researchers at UNC and in China studied more than 750 Chinese men and women, aged between 40 and 59, in three rural villages in north and south China. The majority of study participants prepared their meals at home without commercially processed foods. About 82 percent of the participants used MSG in their food. Those users were divided into three groups, based on the amount of MSG they used. The third who used the most MSG were nearly three times more likely to be overweight than non-users.
北卡罗林娜大学在中国的研究者选取了750名以上的男性和女性居民，他们来自中国南部和北部的三个乡村地区，年龄在40到59岁之间。他们中的大部分在家做饭并且不使用经商业加工的食物。大约有82%的调查对象在食物中使用味精。根据味精使用量的大小将这些人划分为三组。摄入量最高的那三分之一调查者产生超重的危险性是不食用味精的人的近三倍。
"Animal studies have indicated for years that MSG might be associated with weight gain," said Ka He, M.D., assistant professor of nutrition and epidemiology at the UNC School of Public Health. "Ours is the first study to show a link between MSG use and weight in humans."
“近年来动物实验的研究结果表明味精可能与体重增加有关，”北卡罗林娜大学公共卫生学院营养与流行病系的助理教授Ka He医学博士说。“我们的研究首先揭示了味精和人类体重之间的联系。”
