A small study has found that obese children are more likely than others to have a weak sense of taste. German researchers tested tasting ability in 99 obese and 94 normal-weight children, whose average age was 13, by having them try to identify tastes on strips of filter paper and asking them to distinguish among sweet, sour, salty, umami (savory) and bitter. The children also were asked to rate the taste’s intensity on a five-point scale.
Girls were better than boys at distinguishing tastes, and older children scored higher than younger; there were no differences by ethnicity. Obese children scored an average of 12.6 out of a possible 20, while the normal-weight children averaged 14.1, a statistically significant difference.
On the intensity scale, obese children rated all flavor concentrations lower than did those in the normal-weight group.
