Objectivity of food-symptomatology surveys. Questionnaire on the "Chinese restaurant syndrome".
The Chinese restaurant syndrome consists of a characteristic symptom complex, with limited times of onset and duration after eating in a Chinese restaurant. There is widespread belief that the C.R.S. is due to monosodium glutamate used in preparing food in Chinese restaurants and that as many as 25 per cent of the general population may be susceptible to the syndrome. Questionnaires were developed to determine the unpleasant symptoms which 530 subjects associated with specific foods, eating places, and "ethnic" styles of preparing food. Over 90 per cent of respondents associated unpleasant symptoms with specific foods, but only 6.6 per cent experienced an event which would "possibly" represent the characteristic C.R.S. Nevertheless, when the phrase "Chinese restaurant syndrome" was introduced in a second questionnaire, 31 per cent of respondents believed that they were personally susceptible to it. Many people do experience unpleasant symptoms after eating, and particularly after eating food associated with a different culture. Although the responses to food symptomatology questionnaires represent an important aspect of the sociology of eating behavior, this procedure should not be considered an objective data collecting system.
