Portage Learning Nutrition Module 1
Nutrition Ans- the science that links foods to health and disease.
It includes the processes by which humans ingest, digest, absorb, transport, and excrete food
substances.
Physical Health Ans- body's ability to perform daily functions for survival
Intellectual Health Ans- The cognitive ability to learn and adapt
Emotional Health Ans- The ability to express or suppress emotion
Social Health Ans- The ability to interact with others
Spiritual Health Ans- Purpose for human existence, cultural practices
Food Ans- Provides energy in terms of calories
Nutrients Ans- Substances found in food that provide the materials for building and maintaining our
bodies and regulating of key metabolic processes that sustain life
Hunger Ans- The internal drive often experienced as a negative sensation such as churning, growling, or
a painful sensation in the stomach
Appetite Ans- The external drive often related to pleasant sensations associated with food and can lead
us to eat even if we are not hungry
Satiety Ans- The feeling of being full
, Hypothalamus Ans- The region of the brain that plays a role in hunger as well the feeling of being full
gastrointestinal (GI) tract Ans- the main site in the body used for digestion and absorption of nutrients.
The GI tract also contributes to the feeling of satiety.
The GI tract consists of the mouth, esophagus, stomach, small intestine, large intestine, rectum, and
anus
Hormones Ans- compounds secreted into the bloodstream by one type of cell that acts to control the
function of another type of cell.
Hormones that increase hunger Ans- ghrelin, endorphins, neuropeptide-Y
Hormones that decrease hunger (cause satiety) Ans- leptin, serotonin, cholecystokinin (CCK)
Leptin Ans- alerts the brain to turn off the hunger center and activates the satiety center when
consuming a meal. production occurs in adipose (fat) cells.
Ghrelin Ans- produced by the stomach and has an opposing role: Traveling to the brain, it stimulates the
hunger center as it deactivates the satiety center.
Four external forces that influence our food choices Ans- Sensory
Cognitive
Environmental
Health Status
External Force: Sensory Ans- Flavor, texture, and appearance
External Force: Cognitive Ans- Habits, comfort foods, advertising, social factors, nutritional value
External Force: Environmental Ans- Economics, lifestyle, cultural/religious beliefs, environment
