-Provide energy-Yield 4 kcal/gram
Monosaccharides (aka simple carbs)
Glucose (blood sugar)- main fuel for the brain and needed for RBC's.- body uses this form the most.- absorbed in the main intestine.fructose- sweetest of all sugars- honey and fruitsgalactose- sources found in milk/dairy products
12 carbon atomsSucrose (table sugar)- hydrolyzed into glucose and fructose - most commonLactose (milk sugar)- hydrolyzed into glucose and galactose Maltose (plant sugar)- hydrolyzed into two glucose molecules
Polysaccharides (complex carbs)
contain more than 10 monosaccharidesStarch- storage form of energy in plantsGlycogen- storage form of energy in humans (muscle + liver)Fibers- 20-35mg/day
accumulation of ketones in the blood, or in completely oxidized fatty products.
greater than 130 mg/dl BEFORE mealsorgreater than 180 mg/dl 2hrs AFTER meal
less than 70 mg/dl
20 amino acids main function to build new and repair old body tissuescontains: carbon, hydrogen, oxygen and nitrogen.principal source of nitrogen for the body and are fundamental component of every human cell.
fat soluble vitamins
A, D, E, K
Classes: retinoids + carotenoidsFunction: visiongrowthcancer preventiondietary source:beef liver, egg yolk, milk, carrots, squash, spinachdeficiency: growth failure, dry skin, eye disorder
Function: helps absorb calcium and phosphorus + formation of bones and teethdietary source:synthesized in skin exposed to sunlight, fortified foods and fishdeficiency: rickets- disturbance of normal bone formation (infancy and childhood)osteomalacia- softening of bones in adults + loss of lamina dura
Function: acts as anticoagulant (blood thinner)preserves fatsdietary source:seed oils, green leafy veggies, and whole grainsdeficiency: interferes with vitamin K activity
Function: aid in formation of blood clotting dietary source:green leafy veggiesdeficiency: hemorrhaging
Function: energy to the brain, heart and CNSdietary source:pork, grains, milk, sunflower seedsdeficiency: beriberi= neuropathy, diarrhea, weight loss, fatigue, and poor memory.+ muscle weakness, damage to nervous and cardiovascular system.
water soluble vitamins
ALL B vitamins + C
Function: growth and production of RBC'sdietary source:beef liver, milk, steak, mushroomsdeficiency: angular cheilosis, glossitis, dermatitis
Function: energy productiondietary source:plant + animal foodsdeficiency: pellegra- degeneration of the skin, GI tract and nervous system, - dermatitis, diarrhea, depression or dementia, and death
Pantothenic acid (B5)
Function: carbs, fat and protein metabolismdietary source:animal foods, whole grain cereals, bacteria in digestive tract produce B5deficiency: very rare, burning sensation in feet, may impair healing of oral tissue
Function: conversion of tryptophan to niacindietary source:meat, poultry, fish, bananas, nuts, whole grains, veggiesdeficiency: toxicity severe ataxia (impaired coordination) and sensory neuropathyrarely occurs alone, commonly observed with other B deficiencies, CNS abnormalities or convulsions.
Function: synthesis and oxidation of fats and carbs + maintains metabolic homeostasisdietary source:egg yolk, liver, cerealsdeficiency: pallor of the tongue+ patchy atrophy of the lingual papillae
folic acid folate (B9)
Function: formation of neural tube during first month of fetal development dietary source:beef liver, veggies, cereals, grains, legumesdeficiency: ulcerations on the tongue and oral mucosa + glossitis
Function: coenzyme in conjunction with folate metabolism in DNA synthesis dietary source:animal products + fortified plantsdeficiency: pernicious anemia- body cannot absorb B12 in GI tractglossopyrosis- unexplained pain, burning of the tongue
Vitamin C (ascorbic acid)
Function: improving immune system response + collagen formationdietary source:citrus fruits, tomatoes, green peppersdeficiency: scurvy- can occur in 20 days, can see diarrhea, fatigue, depression, and cessation of bone growth.
