NR228 EXAM 1 REVISION
SUMMARY
Insoluble fibers
Cellulose, Hemicellulose and Lignin
Ex: fibrous structures found in the strings of celery and the
skins of corn kernels.
Soluble Fibers
pectins, gums, mucilages
Ex: kidney beans, lentils, chickpeas
health benefits of fiber
Obesity: Fuller Feeling
Constipation: softens stools
Diverticular Disease: Keeps BM's bulk, not stuck in
diverticula
Colon Cancer: replaces fat, linked to cause the cancer
Heart disease: fat is excreted with fiber
Diabetes: increases glucose absorption
Daily amount of fiber necessary
25-38%
AMDR Protein Range
10-35%
AMDR Fats range
20-35%
AMDR Carb range
45-65%
Protein kcal/g
4 kcal/g
, Carb kcal/gram
4 kcal/gram
fat kcal/g
9 kcal/g
Alcohol kcal/g
7 kcal/g
BMI Calculation
(LB*703)/(height in inches squared)
BMI underweight ranges
<18.5
BMI Normal ranges
18.5-24.9
BMI overweight ranges
25-29.9
BMI Obese ranges
above 30
Carbohydrate function
Most effective source of fuel
Protein function
-provide energy
-plays a major role in the structure of:
bones, muscles, enzymes, hormones, blood, immune
system and cell membranes.
Fats function
-densest form of energy
-component in the structure of cells, hormone synthesis,
and padding to protect organs.
Vitamin function
-Assist other nutrients through the digestion, absorption,
metabolism and excretion
-vitamins B and C: water soluble, easily excreted in urine
