Does it really cause headaches?
(HealthDayNews) -- If you think Chinese takeout causes you headaches because of all the monosodium glutamate (MSG) that's used to bring out the flavor of various foods, you'll be surprised at this Harvard study.
According to the Journal of Nutrition, MSG may not cause headaches after all.
University researchers found 130 people who complained of MSG headaches and got them to try foods with and without MSG. They also gave them samples of plain MSG.
Some of the people who had reported MSG headaches did react when they were given pure MSG. But none of them had any reaction when the MSG was mixed with food.
