Quantitative Evaluation of Bitter Taste in Obesity

May 9, 2017 updated by: Julio Sergio Marchini, University of Sao Paulo

Anthropometric Variables and Perception of Bitter Taste in Obese Adults or Not

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.

Detailed 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.
