Title: Nutrition: Carbohydrates

  • Chapter 5
  • Lesson 2

  • Objective 1 Describe the functions of the six
    basic nutrients in maintaining health.
  • Objective 2 List nutrients in a variety of
  • Objective 3 Explain the relationship between
    nutrition, health promotion, and disease

What is a Carbohydrate?
  • Carbohydrates (Carbs)- The starches and sugars
    found in foods.
  • Made up of carbon, oxygen, and hydrogen
  • The bodys preferred source of energy
  • Carbs provide, 4 calories per 1 gram

  • Your body uses the energy from the carbs
    everyday, for every task.
  • Depending on their chemical make-up there are 2
  • Simple
  • Complex
  • 55-60 of your daily calories should come from
    complex carbs.

Simple Carbohydrates
  • What are simple carbohydrates?
  • Also know as EMPTY CALORIES
  • Sugars fructose and lactose
  • Found primarily in fruit and milk
  • Most familiar Sucrose
  • Found naturally plants
  • Refined to make table sugar
  • Sucrose is also added to manufactured foods

Simple Carbohydrates
  • Splenda

  • Sugar counterfeits tricking your body.
  • Artificial sweetener, Splenda, harmful?

Corn, Bad for you? How?
  • Article
  • Read quietly to yourself
  • The vast majority of the high fructose corn syrup
    containing 55 fructose is used to sweeten
    carbonated soft drinks and other flavored
    beverages. Minor amounts are used in frozen dairy
    products. Essentially all foods listing high
    fructose corn syrup as an ingredient contain the
    syrup with 42 fructose. The 95 fructose corn
    syrup is becoming more common in beverages,
    canned fruits, confectionery products and dessert
  • Now, a quarter of the 45,000 items in the
    average supermarket contain processed corn, often
    in the form of high-fructose corn syrup.
  • Thats11,250 products

Complex Carbohydrates
  • What are complex carbohydrates?
  • Starches
  • Found primarily in whole grains, nuts, seeds,
    legumes and tubers (root veggies)
  • Did you know?
  • Your body must break down complex carbs to simple
    carbs before it can use them for energy

Complex Carbohydrates
The Role Of Carbohydrates
  • Your body converts all carbs to Glucose
  • A simple sugar thats the main source of energy
    for our bodies
  • The glucose that is not used is stored in the
    liver and muscles as a starch-like substance
    called glycogen.
  • When your body needs more energy the glycogen is
    converted back to glucose.
  • Excess carbs taken in and not used are converted
    to body fat

Fiber, What is it? What does it do?
  • Is an indigestible complex carbohydrate that is
    found in tough, stringy parts of vegetables,
    fruits and whole grains.
  • Fiber helps move waste through the digestive
    system and helps prevent against constipation.
  • Why fiber reduces the risk of early death is
    unclear. Perhaps it's because fiber lowers levels
    of "bad" LDL cholesterol, improves blood glucose
    levels, reduces inflammation, and binds to
    potential cancer-causing agents, helping to flush
    them out of the body, says lead author Yikyung
    Park, a staff scientist at the National Cancer
    Institute. (article from us

  • Did you know?
  • That if you eat enough fiber throughout your
    life, it can help prevent against heart disease!
  • It can also help control diabetes by reducing
    your blood glucose levels
  • Eat between 20-35 grams of fiber a day!
  • Sources
  • Fruit
  • Vegetables w/edible skins
  • Whole grains
  • Bran, cereal, oatmeal, brown rice

How to get the Proper amount of Fiber
  • Start your day with a whole grain breakfast
    cereal Oatmeal!
  • Choose whole fruit instead of fruit juice
  • Eat 5 servings of fruit and vegetables a day!
  • Select high-fiber snacks
  • Popcorn (no butter), raw veggies, nuts, apples,
    pears, peaches, plums (edible skin)
