Eating Patterns and Intervention Module 3 Flashcards
What is hunger?
Biological drive that impels the ingestion of food
Hunger is a fundamental physiological need that drives individuals to seek food.
Define satiation.
(intra meal) the sensation of fullness during an eating episode that contributes to the cessation of eating
Satiation is crucial for determining when to stop eating during a meal.
What does satiety refer to?
(inter meal) the sensation of fullness between eating episodes that tends to inhibit the resumption of eating
Satiety helps regulate the intervals between meals.
What is the Satiety Index Score?
A calculated value based on a subject’s satiety ratings after consuming various foods
This score helps to compare the satiating effects of different foods.
Define sensory-specific satiety.
The changing hedonic response to the sensory properties of a particular food as it is consumed
This concept explains why people may lose interest in a specific food after eating it for a while.
What is energy density?
The caloric value of a food per unit weight or volume
Foods with high energy density provide more calories in smaller portions.
Define palatability.
A subjective measure of a food’s pleasantness
Palatability influences food choices and consumption patterns.
What is passive over-consumption?
A non-deliberate ingestion of excess calories in which signals for satiation do not function effectively to control meal size
This phenomenon can contribute to overeating and weight gain.
food characteristics, ex tastes volume and weight , energy density, osmolarity, macronutrients
sataety signnals
What are biological responses to satiety?
oral stimulations
stomach distenstion and gastric emptying( feeling full, ghrelin, hunger)
Hormones
Plasma nutrients
What effect do foods with higher satiety have on inter meal periods?
Foods with higher satiety tend to produce longer inter meal periods.
What effect do foods with lower satiety have on intra meal periods?
Foods with lower satiety tend to produce shorter intra meal periods.
Can macronutrients with the same caloric content exert different effects on satiation and satiety?
Yes, macronutrients with the same caloric content can exert different effects on satiation and satiety independent of the caloric value.
Are all calories treated equally by the body?
No, not all calories are treated equally by the body.
What is NST in relation to neurotransmitters?
NST stands for Nucleus of Tractus Solitaris.
What hormones are involved in physiological and metabolic responses?
Hormones like CCK, Insulin, Glucagon Like Peptide (GLP-1), and Leptin are involved.
What factors contribute to satiety signals?
Factors include taste, volume and weight, energy density, osmolarity, and macronutrient distribution.
What is sensory specific satiety?
Sensory specific satiety is the sensation past the period when food is physically in contact of pressure and stretch receptors.
What is noted about high protein foods in relation to satiety?
High protein foods appear to be most satiating; fats are the least and CHOs are in between.
What is a consequence of consuming calorically dilute foods?
Consumption of calorically dilute food leads to increased food volume, increased satiety, and decreased caloric intake.
What is one goal in eating disorder treatment regarding food choices?
One goal is to normalize food choices so that unadulterated foods are most frequently chosen.
-lowers total volume which allows pressure receptors to influence food intake without being the dominant mechanish
what is the number 1 reason for eating specific foods
taste
accetability of food that promotes the selection intake and obsorption and digestion of foods?
palatability
Low energy dense foood more water less fat
Satiating? palatable?
less palatable and more satiating
