essential nutrients - CORRECT ANSWERS nutrients body cannot make itself
6 major essential nutrients - CORRECT ANSWERS Carbohydrates
protein
fat
vitamins
minerals
water
Carbohydrates role in body - CORRECT ANSWERS -4cal/g
-energy-yielding nutrient
-2 groups: simple & complex
Simple: sugars Complex: starch & dietary fiber
-energy used first to fuel muscles and brain
-(45-65% of calories should come from carbohydrates

corn bran, whole grain breads and cereals, vegetables, fruit skins, nuts
-don't provide any calories
-helps alleviate digestive disorders like constipation or diverticulitis and may
prevent colon cancer
Proteins role in the body - CORRECT ANSWERS -4cal/g
-broken down into amino acids by the digestive system
, -amino acids are then used for building and repairing muscles, red blood cells, hair

-best consumed through a varied diet rather than as a supplement bc there is little
chance of taking too high a dose
Minerals role in body - CORRECT ANSWERS -REGULATOR
-assist in all body processes
-components of foods that are involved in many body functions
-ex: calcium & magnesium important for bone structure
-ex: iron needed for red blood cells to transport oxygen
-not a source of energy
-best obtained through a varied diet rather than supplements
Water's role in body - CORRECT ANSWERS -vital nutrient for good health
-body cells cannot function without water
-most of our body weight (60-70%) is made up of water
-helps control body temperature, carries nutrients and waste products from cells,
and is needed for our cells to function
-recommended that adults drink 8 glasses of fluid daily (or more)
-fluid does not have to be water alone - it can be obtained from juice, milk, soup &
foods high in water such as fruits & vegetables
