Everything you eat contains nutrients
Your body uses nutrients as: an energy source, to heal, build and repair tissue, sustain growth,
help transport oxygen to cells, and to regulate body functions
The six types of nutrients are carbohydrates, proteins, fats, vitamins, minerals and water
Each gram of carbohydrate or protein is 4 calories; each gram of fat is 9 calories
#3 types of carbohydrates are simple, complex, and fiber
Simple carbohydrates are sugars – fructose found in fruits, lactose found in milk
Complex carbs, or starches, are long chains of sugars linked together. Common sources are
grain and grain products
Fiber is a carbohydrate that moves waste through your digestive system
Vegetables and fruits are very good sources of fiber
Most carbohydrates are turned into a simple sugar called glucose, the main source of fuel for
the body. Glucose can be stored in your body’s tissue and used later
Proteins are made up of chemicals called amino acids
Your body uses 20 amino acids, 9 of these are essential acids. They are called essential because
your body cant produce them and they get them from animal sources and soy
Protein is the basic building material of all your body cells
3 types of fats are unsaturated fats, saturated fats, and trans fats
The essential fatty acids are important to: Brain development, blood clotting, controlling
inflammation, and maintaining healthy skin and hair
Because your body cant produce minerals, it must get them from food
Eating calcium rich foods reduces your risk of developing osteoporosis
Water is essential for just about every function in your body
