Title: CARBOHYDRATES


1
CARBOHYDRATES
  • A Complex Story

2
Carbohydrates Carbon Water
  • Carbs are sugar compounds that plants make when
    theyre exposed to light.
  • Carbs come in three varieties simple, complex,
    dietary
  • Each differs with number of sugar units and how
    the units are linked together

3
Simple Carbohydrate
  • These carbohydrates have only one or two units of
    sugar.
  • Examples fructose and sucrose

4
You know the buzz you get after eating one of
these?
5
That is because
  • Simple carbohydrates (sugar) like table sugar,
    honey, candy, and the like, are digested quickly
    and give your body an energy surge.

6
Unfortunately
  • I'm sure you know the crash you feel soon after,
    too. You have some energy for a while and then
    you zone out. That's a simple carb for you,
    alright they leave you high and dry.

7
Heywhat about me???
8
Yes, Fruit is a Simple Carb
  • Like candy, fruit is also quickly turned into
    glucose and used by your body for quick energy.
  • Unlike candy, fruit also gives you vitamins and
    minerals.
  • Eat this
  • Not this

9
Complex Carbohydrates
  • These have more than two units of sugar.
  • Starches such as pasta, rice, and potatoes are
    complex carbohydrates.

10
Kinder, Gentler Carbs
  • The complex carb is the good guy of the
    carbohydrate world.
  • Most are high in nutrient value.

11
Why you feel full longer
  • Your body takes longer to digest them than simple
    carbs.
  • As a result, glucose is released more slowly and
    evenly into your bloodstream than simple carbs.

12
Carbohydrates and Energy
  • A biochemical love story

13
When you eat carbohydrates
  • Your pancreas secretes insulin (the hormone that
    lets you digest starches and sugar)
  • Eating simple carbs (sugar) provokes higher
    insulin secretion than complex carbs (starch)

14
How does that pasta end up on your hips?
15
Heres how we gain weight
  • Your cells budget energy very carefully and do
    not store more energy than they need right now.
  • Any glucose not needed for daily work will be
    stored in liver and muscles.
  • BUT, more than about 1800 calories of energy and
    this will be converted to fat.

16
Dietary Fiber (the 3rd type of carbohydrate)
  • Ummdo you mean something disgusting like stewed
    prunes??

17
Dietary Fiber A different kind of carbohydrate!
  • Dietary fiber is not like other carbohydrates.
  • Like complex carbs, it contains more than two
    units of sugar.
  • However, the bond that holds its sugar units
    together cannot be broken by human digestive
    enzymes.

18
These have lots of fiber
19
Cannot digest it? Why eat it?
  • Insoluble Fiber (does NOT dissolve in water)
  • Found in whole grains and vegetables
  • Soluble Fiber (DOES dissolve in water)
  • Found in fruits (pectin), oats and barley, beans,
    seeds

20
Benefits of Fiber
  • Insoluble fiber
  • A natural laxative
  • Absorbs water, helps you feel full after eating
  • Soluble fiber
  • Seems to lower cholesterol level
  • This may be why a fiber rich diet is good to
    prevent heart disease

21
Do you agree with this?
22
How much carbs do you need?
  • 45 to 65 of your daily calories should come from
    carbs
  • 6 -11 servings of grain goods (bread, cereals,
    pasta, rice)
  • 2 - 4 servings of fruit
  • 3 - 5 servings of vegetables
