Carbohydrates:
A Complex Story
Checking Out Carbs
• ”carbon plus water”• Sugar compounds
made by plants when the plants are exposed to light
Simple or Complex?
• Simple carbs ~ 1 unit of sugar is called a monosaccharide (ex. Frutose), 2 units ~ disaccharide (ex. Sucrose ~ table sugar)
• Complex carbs ~ more than 2 linked together, ex. Starch ~ found in potatoes, pasta
• Dietary Fiber ~ fiber in food (not fabrics!!), ex. Cellulose, cannot be broken down
Carbs and Energy:A biochemical love story
• Body runs on glucose• All digestible carbs are converted into
glucose- glucose is carried to cells by insulin
• Any glucose cell the body does not use is stored in liver and muscles (400 grams max)
• Excess is converted to fat…that is how pasta ends up on your hips!
Other ways the body uses carbs…
• Regulate the amount of sugar circulating in the blood
• Provide nutrients for the friendly bacteria in your intestinal tract that help digest food
• Assist in body’s absorption of calcium
• May help lower cholesterol levels & help regulate blood pressure
Consuming Carbs…
• 6-11 servings of grains• 2-4 servings of fruit• 3-5 servings of vegs• 1 gram of carbs = 4
calories• One bagel has 38 grams,
equal to 152 calories (38 x 4)
• There may be other calories if the product contains fat, protein, etc.
Fiber• Found in all plant foods…
absolutely no fiber found in foods from animals (meat, fish)
• Females need 15 grams a day…males need 38 grams
• If you eat more than enough fiber- your body will tell you…all the roughage may irritate your intestinal tract which will issue an unmistakable protest in the form of intestinal gas or diarrhea.
• If you do not drink enough liquids to carry the fiber then you could end up with an intestinal obstruction!
• Getting fiber from food
