About

Although taste influences food choices and favours diseases like obesity, there is no consensus about the existence of correlations between bitterness and anthropometric variables. Also, an electronic-based method for data collection could provide a more appropriate way for the evaluation of taste perception and save time.

The objective is to search for correlations between bitterness and anthropometric variables.

Full description

A cross-sectional study evaluating correlations between the bitterness rates given on a generalized Labeled Magnitude Scale, anthropometrics and other variables. Bitterness perceptions at the tip of the tongue (TOTp) and at the whole mouth (WMp) were recorded using a locally developed novel cloud-based software (Cloud-gLMS). The ANCOVA test was adjusted using TOTp and WMp as dependent variables and age, height, weight, BMI, gender, waist circumference, alcohol intake, comorbidities, and use of medications as independent variables.
