Carbohydrates- 1. Complex – Long chains of carbon. (For Example: Grains: wheat, rice, bulgur) a. Forms starch molecules b. Contain B Vitamins c. Help satisfy hunger and control appetite because of their digestibility and effect on blood sugar d. 4 calories/ gram
Simple – Short chains of carbon (For Example: Fruits) • 6 carbons for monosaccharide, 12 for disaccharide • 4 calories/ gram • Rapidly digested with immediate effect on blood sugar • Some vitamins and minerals are associated with natural sources like fruit • Processed sources (sugar) are nutrient dilute
Fiber – Long chains of carbon (For Example: Vegetables) • Mostly water based so they have few calories per serving • It takes a lot of fiber to weigh one gram • 4 calories/ gram • Important ingredient for digestive health
Remember: • Most plant sources are combinations of 1 or more types of carbohydrates • Some protein sources contain carbohydrates (simple) in the form of glycogen, stored energy for the animal to use
Each type responds differently to heat & cooking • Starches: gelatinize • Sugars: caramelize • Fiber: water evaporates so cell walls soften
