Energy intake and diet selection during buffet consumption in women classified by the 6-n-propylthiouracil bitter taste phenotype

Abstract

NT and MT women consume more daily energy than do ST women when eating in a buffet setting, which is a common type of dietary exposure. This increase in energy intake over time could contribute to a positive energy balance and increased adiposity previously reported in these women.

Influences of weight, age, gender, genetics, diseases, and ethnicity on bitterness perception: a narrative review of current methodological aspects

“…2007 [23] In pre-adolescent children, current energy intakes were negatively related to children's PROP status and positively related to maternal disinhibition Shafaie et al 2013 [24] Non-taster and medium taster women consume more daily energy than do supertaster women when eating in a buffet setting, which is a common type of dietary exposure…”

“…On the other hand, overweight subjects older than 65 years were more sensitive to bitterness (p = 0.015) [5]. Similarly, Tepper et al [22] suggested an inverse correlation between perception of PROP bitterness and energy consumption and/or BMI [23][24][25]. However, this same study group highlighted that other factors may have a role in the definition of the affinity for the taste [47] Differences in palate between genders is specifically due to hormonal influences on the salivary components Khataan et al…”

Consumption of a high-fat soup preload leads to differences in short-term energy and fat intake between PROP non-taster and super-taster women

“…Most diet studies depend on self-reported food intakes that are less reliable than direct dietary measures (Karelis et al, 2010). When we measured food intake in the laboratory during a buffet feeding regimen, lean, non-taster women consumed more energy than did supertaster women (Shafaie et al, 2013;Tepper et al, 2011). Further, when examined over multiple days of laboratory feeding, non-taster women consumed more servings of added fats and sweets such as cakes and pastries (Shafaie et al, 2013).…”

Taste perception, associated hormonal modulation, and nutrient intake

“…127 When exposed to three consecutive days of buffet consumption, young, healthy-weight women who were nontasters consumed more energy and a greater percentage of energy from fat compared with super tasters. 128 Additionally, nontasters consumed more energy from between-meal snacks and sweets, while super tasters consumed more fruits and vegetables. While this was a population of lean, moderately active women, eating patterns that include high fat content, minimal fruits and vegetables, and frequent snacking are often associated with weight gain.…”
