Carbohydrates
  • Nutrition Wellness

2
  • Carbohydrates should be 55 60 of the diet
  • Broken down into three levels
  • Monosaccharides
  • Disaccharides
  • Polysaccharides

3
Monosaccharides
  • Single Sugar Units
  • Simple Carbohydrates
  • Glucose blood sugar
  • Fructose sweetest tasting
  • Galactose bonded to glucose

4
Disaccharides
  • 2 sugar units
  • Simple Carbohydrates
  • Splits into Monosaccharides during digestion
  • Sucrose table sugar (glucose fructose)
  • Maltose formed during starch digestion (2
    glucose)
  • Lactose milk (glucose galactose)

5
Polysaccharides
  • Multiple sugar units
  • Complex Carbohydrates
  • Should be 20 of the diet
  • Starch
  • insides of plant cells
  • many glucose cells
  • Ex breads, cereals, starchy veggies (corn,
    potatoes) beans
  • Fiber
  • cell walls
  • broken down by bacteria in the system
  • Only found in plants
  • Males 38g Females 26g

6
Fiber
  • Soluble
  • Dissolve in water
  • Lower blood cholesterol levels
  • Oat bran
  • Legumes
  • Apple Citrus pectins
  • Insoluble
  • Do not dissolve in water
  • Associated with reducing cancer
  • Wheat bran
  • Whole grains

7
Functions
  • Produce Energy

    of body wastes

8
Sugar
