Abstract
Fast food has been shown to increase the risk of being overweight in children and adults. The objectives of the present study were to investigate the correlation between the rate of chewing and the number of chews per mouthful and to assess whether they were associated with the weight of meal intake. Thirty healthy individuals, aged between 18 and 24 years old, had a test lunch at their usual speed until they were satisfied. The activities of the masseter and suprahyoid muscles were recorded to determine the number of chews and the time of swallowing. The weight of meal intake was recorded along with body mass index (BMI), chewing rate, number of chews per mouthful, meal duration, intake rate, hunger and food preference levels. The mean weight (± SD) of meal intake, chewing rate and number of chews per mouthful were 261.4 ± 78.9 g, 94.4 ± 13.5 min.-1 chews, 19.2 ± 6, 4 chew a mouthful, respectively. The chewing rate did not correlate with the number of chews per mouthful. Multivariable linear regression showed that meal intake was significantly positively associated with chewing rate, meal duration and BMI, but inversely associated with the number of chews per mouthful (adjusted R 2 = 0.42). It was concluded that the number of chews was not associated with the rate of chewing, but the intake of meals was explained both by the reduced number of chews and the increase in the rate of chewing.
