  1. Carbohydrate (Carbs or CHO)
    Composition: Carbohydrate is made of the elements carbon,hydrogen, and oxygen.

    Organic Compound: Carbohydrate is organic because it contains carbon. It is a compound because it has more than one element in its structure.
  2. Monosaccharides
    • Glucose
    • Fructose
    • Galactose
  3. Disaccharides
    • Sucrose
    • Maltose
    • -Lactose
  4. Simple Sugars:
    Monosaccharides

    Disaccharides
  5. Common Names of Sugars
    • – Glucose is blood sugar
    • – Fructose is fruit sugar
    • – Sucrose is table sugar
    • – Lactose is milk sugar
    • – Maltose is malt sugar
  6. Complex Carbohydrates

    Polysaccharides:
    Starch (digestible & caloric)
    – Alpha linked glucose molecules in starch can be broken apart by the enzyme alpha-amylase to produce energy.

    – The glucose units that are released are absorbed into the blood stream.
  7. Complex Carbohydrates

    Polysaccharides:
    Fiber (indigestible & noncaloric)
    • – Beta linked glucose molecules cannot be broken apart by human enzymes so no energy is produced.
    • – The glucose units are not released and thus fiber is not absorbed.
    • – Cellulose is the most common type of fiber.
  8. Carbohydrate Food Sources
    • Grains, Cereals, & Legumes:Pasta, bread, cold/hot cereal,rice, oats, kidney beans, etc.

    • Fruits & Vegetables

    • Starchy Vegetables: Corn,potato, peas, acorn squash, etc.
  9. Plant Carbohydrate Sources
    • Simple carbohydrates:Fruit, table sugar, sweets &sugar sweetened cereals.

    • Complex carbohydrates:Vegetables, starchy vegetables, grains,legumes, & whole grain cereals.
  10. Animal Carbohydrate Food Sources
    • Milk (& milk products yogurt &cheese) contain lactose.

    • Honey contains glucose, fructose &small amounts of other sugars.

    • Animal foods usually provide mostly protein & fat.

    • Milk & milk products also provide protein & varying amounts of fat.
  11. How much carbohydrate do you need?

    The Acceptable Macronutrient Distribution Range (AMDR) is:
    45-65% of Calories from carbohydrates

    Subunit:

    <25% of Calories from sugars
  12. How much fiber do you need?
    The dietary recommendation for fiber is 1.4 gram per 100 Calories consumed
  13. Alcohol: CH3CH2O
    • • Provides 7 Calories/gram.
    • • Is a carbohydrate related substance.
    • • Lacks nutritional value.
    • • Is a CNS depressant.
    • • Is considered a drug.
    • • Is commonly ingested.
    • • One serving per day may reduce heart disease risk but increase cancer risk.
