Sensor-specific saturation what it is, how it works
Table of Contents
1. It's sensory-specific
Satisfaction is a state of satiety, and it is accompanied by a feeling of fullness in the stomach, which lasts until hunger reappears. But why is it so often the opposite and appetite increases as you eat? Sensory-specific satiety (SSS) is one of the mechanisms that regulates food intake. It is caused by a weakening of the response of neurons in the brain that are responsible for sensory stimulation. At the same time, the reception of different sensory stimuli remains unchanged.2. Sensory specificity of the test
Deysher's 1986 study was designed to demonstrate the existence of two behavioral mechanisms associated with self-regulation of food intake and sensory-specific satiety. Sensory-specified satiety data were collected directly before and after meals. The study provided the first evidence of SSS in children as well. Di Pellegrino, S. Mengarelli, and S. Magarelli. Study participants determined the level of sensory pleasure experienced by the senses tested before eating and after eating. The women consumed them to a saturated level.3. Sensor-specific saturation and age
McDermott studied the effects of age on sensory-specific satiety. The subjects evaluated pleasurable sensory properties and the desire to eat five foods. There was also no decrease in appetite for food eaten. B.J. The study involved young people (1215 years), young adults (2235 years), older people (4560 years) and elderly people (6582 years).4. Sensory-specific satiety and a varied diet
The subjects ate any amount: 1) fries, then cakes, 2) ketchup and mayonnaise fries and then vanilla cream and cream biscuits, 3) french fries then ketchups, mayonnaises, cakes alone, cookies with additives. The consumption of the fries alone caused a decrease in pleasure, but the addition of ketches led to overconsumption. Adding to previously consumed foods, such as ketches or mayonnais, also increased sensory portion intake.5. Sensor-specific saturation and BMI
The study involved 290 adults, of whom 161 were normal body weight, 78 were overweight, and 51 were obese. They ate as much as they wanted. The researchers also found that obese people's pleasure from eating decreased more slowly than the rest of the participants. The sensory properties of the products were also important.6. Sensor-specific satiety and weight loss
On the other hand, sensory-specific satiety can trigger hyperphagia (over-consumption). G.R. Research has shown that even after a meal, people feel the urge to consume another product. Sensory-specified satiety is influenced by many factors, including chewing time. It also causes sensory fatigue, which ends a meal. Monotonous, little-differentiated meals will be consumed in smaller quantities. Eventually, through SSS, we stop eating a given meal and reach for completely different, different sensors.
