Foods Containing Carbohydrates One gram of carbohydrate provides a body with four Calories of energy.
Food and Energy
Define:Nutrients = The substances in food that provide the raw materials and energy the body needs to carryout essential processes.
Carbohydrates = major source of energy. Made of (C,H, O2)Provide raw materials to make cell parts.
Glucose = a simple carbohydrate, a type of sugar and major energy source
Fats = high energy containing nutrients, 1gram of fat= 9 caloriesMade of (C,H, O2)

Final Digestion and Absorption
Three Groups of NutrientsDescribe the different kinds of nutrients and explain how each structure helps food become materials the body can use.
Final Digestion and Absorption
