AI Article Synopsis
- The study investigates the relationship between sweet taste perception and feeding behaviors in individuals with severe obesity compared to healthy volunteers, highlighting inconsistencies in previous research.
- Using validated taste assessment methods, the analysis showed that individuals with obesity tend to rate sweet tastes more intensely, which correlated with greater hedonic hunger and food addiction symptoms.
- The findings suggest that sweet taste perception may not be directly related to psychological measures of food reward, indicating a different dimension of behavior associated with obesity.
Article Abstract
Introduction: While sweet taste perception is a potential determinant of feeding behavior in obesity, the supporting evidence is inconsistent and is typically associated with methodological limitations. Notably, possible associations between sweet taste perception and measures of food reward remain undetermined.
Materials And Methods: We conducted a cross-sectional analysis comparing 246 individuals with severe obesity and 174 healthy volunteers using a validated method for taste perception assessment. We included gustatory variables, namely intensity and pleasantness ratings of sour, salt, sweet, and bitter tastants, and taste thresholds assessed by electrogustometry. Reward-related feeding behavior, including hedonic hunger, food addiction, feeding behavior traits, and acceptance of foods and alcohol, was evaluated using self-rated scales for comparison with gustatory measures.
Result: In logistic regressions adjusted for age, gender, educational level, and research center, we found that a greater likelihood of belonging to the obesity group was associated with higher sweet intensity ratings (OR = 1.4, = 0.01), hedonic hunger, food addiction symptoms, restrained and emotional eating (1.7 < OR ≤ 4.6, all ≤ 0.001), and lower alcohol acceptance (OR = 0.6, = 0.0002). Using principal component analysis, we found that while hedonic hunger, food addiction, and emotional eating were strongly interrelated, they were not associated with sweet intensity perception that, in turn, had a closer relationship with alcohol acceptance and restrained eating.
Conclusion: We found that individuals with obesity report higher sweet taste intensity ratings than healthy controls. Furthermore, while psychological measures of reward-related feeding behavior assess a common construct, sweet intensity perception may represent a different obesity-related dimension.

Aim: Gustatory function plays a fundamental role in various aspects related to nutrition and health, and the decline in taste perception can result in a series of adverse consequences. This is expected with aging due to a decrease in taste buds and other conditions, leading to systemic and oral diseases. We aimed to compare taste sensitivity in the elderly population vs.

Reduced exposure to sweet taste has been proposed to reduce sweet food preferences and intakes, but the evidence to support these associations is limited. This randomised controlled trial investigated the effects of a whole-diet sweet taste intervention for 6 days, on subsequent pleasantness, desire for, and sweet food intakes. Participants ( 104) were randomised to increase ( 40), decrease ( 43), or make no change to ( 21) their consumption of sweet-tasting foods and beverages for six consecutive days.

The effect of frozen storage (-18°C for 2 months) and thawing (4°C for 16 h) on the taste-related compounds and volatile organic compounds (VOCs) in chicken breast meat was studied. After freeze-thawing, inosine monophosphate levels in chicken meat decreased and inosine levels increased. Free amino acid content increased significantly, regardless of bitter, sweet, or umami amino acids.

Fermentation is a key process in Congou black tea, but there is limited research on the changes in flavor factors and their interrelationships during different fermentation stages under industrial production. This study applies sensory evaluation and metabolomics techniques to explore the interactions between flavors. Sensory evaluation indicated that the 4-h fermented sample exhibited the best overall performance.

Three new triterpene glycosides were isolated from x "Strawberry Fields" cultivar via aqueous-ethanolic extraction of the roots, including one derivative of sumaresinolic acid and two of echinocystic acid: 3--β-D-glucuronopyranosylsumaresinolic acid 28--β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl ester, 3--β-D-glucuronopyranosylechinocystic acid 28--β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl ester, and 3--α-L-arabinopyranosyl-(1→3)-β-D-glucuronopyranosylechinocystic acid 28-O-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl ester. As none of the isolated saponins were previously documented in the literature, their structural elucidation required extensive 1D and homo- and heteronuclear 2D NMR spectroscopy, as well as mass spectrometry analysis. All three glycosides were tested for their stimulatory activity of the sweet taste receptor TAS1R2/TAS1R3.
