Document Summary
Essential nutrients: nutrients the body cannot make which must be consumed. Nutrient density: comparison of nutrients versus calories in a food. Unsaturated fatty acid: double bond, is an oil at room temperature, the better kind of fatty acid for your health, example: olive oil. Energy density: comparison of food and caloric content. Digestion: process of breaking down food into absorbable units. Mucus: secreted by mucosal cells to moisten and lubricate gastrointestinal tract lining. Enzymes: proteins found in digestive secretions that break them down into simpler compounds. Peristalsis: forward, rhythmic motion that moves chyme through the digestive system. Chyme: semi-liquid mix of food and stomach acid. Insulin: hormone created in pancreas in response to glucose/a spike in blood sugar, allows glucose to be moved into tissue and distributed into cells. Refined grains: removal of the bran and germ of a whole grain which results in the loss of most nutrients. Enrichment: addition of nutrients back into refined products.
