adequate to meet the needs of all healthy people
EAR (estimated average requirements) - > The amount of a nutrient that will maintain a
specific biochemical or physiological function in ½ the people of a given age and gender
group

maintain health
TUIL (tolerable upper intake levels) - > The maximum amount of a nutrient that appears
safe and beyond which there is a risk of adverse health effects
Enriched foods - > An addition to a food of specific nutrients to replace losses that occur
during processing so that the food will meet a specific standard
,Fortified foods - > Addition to a food of nutrients that were either not originally present or
present in insignificant amounts
Ingredient list - > Listing of all ingredients
Descending order of predominance by weight

Relationship to health
"Ballpark" estimate of contribution to total diet
Based on 2,000 calories per day
Percent daily value
Percentage of a daily value recommendation found in a specified serving of food for key
nutrients based on a 2,000 calorie diet
≥ 20%= high or excellent source
10-19%= good source
≤ 5%= low source
≥ 20% of the daily value - > High or excellent source of the daily value
10-19% of the daily value - > Good source of the daily value
, ≤ 5% of the daily value - > Low source of the daily value
Gastrointestinal tract (GI tract) - > Flexible muscular tube from the
mouth→esophagus→stomach→small intestine→large intestine→rectum→anus
Principal organs of absorption and digestion - > Stomach
Intestine
Lumen - > Inner space within the GI tract
Mouth - > Oral cavity includes lips, teeth, tongue, and palate
Begins digestive process- motility and secretion
Salivary glands- secrete saliva
Contains digestive enzymes for starch (salivary amylase)
4 basic taste sensations: sweet, sour, bitter, salty, and savory (umami)
Tongue- taste sensations and food movement
Bolus - > The amount of food swallowed at one time
Pharynx - > A short tube shared by both digestive system and respiratory system
Epiglottis - > Protects the airway during swallowing
First regulation of intake
Esophagus - > Food pipe- passes food from mouth→ stomach
Primary function= motility
Passes through a hole in the diaphragm
Upper esophageal sphincter - > Opens during swallow
Cardiac or lower esophageal sphincter - > Prevents reflux (backflow of content)
