Rapid eating may increase the probability of developing type 2 diabetes, according to a study presented at the 15th World Congress of Endocrinology and the 14th European Congress of Endocrinology, held in Florence, Italy, in May 2012. The study was conducted as a case-control study and included 243 patients who were newly diagnosed with type 2 diabetes and 468 control individuals who did not have diabetes. The case and control groups (ratio 1:2) were matched according to sex and age (±5 years). Specialized questionnaires were designed to collect information on possible risk factors for type 2 diabetes mellitus. Anthropometric data measurements were performed according to the WHO recommendations. The ratio and 95% confidence interval for type 2 diabetes were calculated by conditional logistic regression. It was found that: the body mass index of the group with diabetes was higher than that of the apparent control group, which means that the fatter the person, the more likely he or she is to get diabetes; the lower the level of foreign education, the more likely he or she is to get diabetes; and people who eat quickly are two times more likely to get type 2 diabetes. Therefore, we advise you to eat as slowly as possible. The recommended eating time should be more than half an hour, and it is best to chew each mouthful of rice for 30 times so as to slow down the eating speed.
