Consumption of monosodium glutamate in relation to incidence of overweight in Chinese adults: China Health and Nutrition Survey (CHNS).

Abstract in brief

• The study investigated whether eating monosodium glutamate (MSG), a flavor enhancer, is linked to gaining weight among Chinese adults, finding that higher MSG intake is associated with increased BMI and a greater risk of becoming overweight over time.
• Researchers analyzed data from nearly 10,095 healthy adults collected between 1991 and 2006, using food inventories, BMI measurements, and statistical models to track how MSG consumption influenced weight gain, accounting for various factors like age, activity level, and diet.
• Results indicated that people in the highest MSG intake group had about a 33% higher risk of overweight compared to those in the lowest group, suggesting a positive relationship between MSG consumption and weight gain, though more studies are needed to understand the underlying mechanisms.]
