The propensity to overeat may, in part, be a function of the satisfaction derived from eating. A new study in the Journal of the Academy of Nutrition and Dietetics, published by Elsevier, found no significant difference in taste perception between participants with normal weight and those who were overweight. However, obese participants had higher initial perceptions of taste than non-obese participants, who declined more slowly than non-obese participants. This quantification of food satisfaction can help explain why some people eat more than others.

"Obesity is a major public health problem." Thirty percent of the US population is obese and health problems related to obesity (diabetes, hypertension, etc.) are increasing. Obesity is varied, but decisions about food consumption play an important role Taste perception can lead to overeating.If obese people have different taste perceptions of non-obese, this could lead to better understanding of obesity and possibly the design of new approaches to the prevention of obesity, "explained lead investigator Linnea A. Polgreen, Ph.D., Department of Practice and Pharmacy Science, University of Iowa, Iowa City, IA, USA.

As individuals consume more food, their perception of marginal taste decreases, which means that their perceived taste level resulting from additional consumption may tend to decrease (ie. That an extra consumption can become less pleasant). The relation between the perceived taste and the quantity consumed is traditionally called sensory satiety.

In order to determine whether marginal taste perceptions differ between participants of normal weight, those who are overweight and those who are obese, and if knowledge of nutritional information affects the perception of marginal taste, researchers of University of Iowa conducted a nonrandomized and clinical controlled study. 290 adults (161 with normal BMI, 78 considered overweight and 51 considered obese) to measure instant perceptions of taste. Eighty percent of the participants were women, and the age ranged from 18 to 75 years old. Participants were offered a chocolate note at a time in a controlled environment and could eat as much as they wanted without feeling uncomfortable. They consumed between two and 51 pieces. Half of the study participants received nutritional information on the chocolate before the start of the tasting.

The study identified a consistent badociation between the taste of foods, particularly chocolate, and BMI by directly observing the instantaneous changes in taste over a given period, rather than at the beginning and at the beginning. end of a consumption period, as in previous studies.

Generally, the appeal of a specific food may decrease as one eats more food: the first bite of chocolate is better than the tenth, a phenomenon consistent with the concept of specific sensory satiety. As expected, the researchers found that notes generally dropped after each piece of chocolate consumed without significant difference in taste perceptions between normal and overweight participants. However, obese participants had an initial perception of higher taste, rated higher scores higher than their non-obese counterparts, and their rankings decreased more gradually than participants with normal weight or obese. People who were more hungry before the study had a better perception of taste; the taste perceptions of women have declined more rapidly than those of men and providing nutritional information before chocolate consumption does not affect the perception of taste.

"In our study population, obese people reported a higher level of satisfaction for each additional piece of chocolate compared to non-obese, so their taste preferences look significantly different," said the co-investigator. Aaron C. Miller, Ph.D., Department of Epidemiology, University of Iowa, Iowa City, IA, USA. "Our findings further indicate that obese participants needed to consume a larger amount of chocolate than non-obese participants to experience a similar drop in taste perception." Specifically, obese women had to eat 12.5 pieces of chocolate to fall in love. at the same level of taste perception as non-obese women who ate only 10 pieces, which corresponds to a difference of 67.5 calories.This may partly explain why obese people consume more than non-obese people. -obese.
