Proteins………
Protein• Builds & Repairs Cells of Muscles, Skin, Hair & Nails• Forms Hormones, Antibodies & Enzymes• 10-35 % of Total Daily Calories• 4 k/cal per Gram• Eat Too Much & it is Stored as Fat
Complete vs Incomplete
Complete Protein• Contains All 9 Essential Amino Acids• Contains Cholesterol
Chicken, Turkey, Pork, Beef, Seafood, Emu, Ostrich, Venison, Antelope, Sausage, Cheese, Dairy….

Peanut butter & BreadRice & BeansTofu & Rice
Fats• Main Form of Energy
Storage• Cushion Organs• Maintains Body
Temperature• Makes Hormones• Helps you Feel Full after

Food
Eating Too Many Can Lead to Obesity Saturated vs
Unsaturated
Saturated Fat• Contain Saturated
Fatty Acids• Are Solid at Room
Temperature• Comes only from
Animal Products with the exception of Coconut & Palm Oil
UnSaturated Fat
• Contain UnSaturated Fatty Acids
• Are Liquid at Room Temperature
• Comes only from Plant Products (Excludes Coconut & Palm Oil)
Vitaminscarbon-containing nutrients that are needed in
small amounts to maintain health and allow growth.
• Vitamins are classified by what they dissolve in: fat or water.
• Fat-soluble vitamins dissolve in fat. As a result, they can be stored in fat tissue and remain in the body for a long time. Examples include Vitamins A, D, E, and K.
• Water-soluble vitamins dissolve in water. They are not stored in the body very well. Such vitamins are the 8 B vitamins and vitamin C.
Mineralschemical elements that are essential in small
amounts to maintain good health.
• Nutrient deficiency is the state of not having enough of a nutrient to maintain good health.
• A well-balanced diet can meet ALL vitamin and mineral needs.
3 Important MineralsSodium
– Most of us eat more sodium than is healthy.
– Too much can lead to high blood pressure resulting in heart disease, stroke, or kidney failure
Calcium– Most teens do not eat enough
calcium. Calcium is found in green, leafy vegetables (broccoli and spinach) and in calcium-fortified foods (bread and orange juice.
– Mostly found in your bonesIron
– Iron-deficiency causes anemia– Red meats are rich in iron.– Anemia is when there are not
enough red blood cells to carry oxygen around the body.
Waterit makes up 60% of your body and is essential for
almost every function to keep you ALIVE.• To be healthy, you should take in at least
2.5 quarts of water each day (about 8 glasses). This makes up for water lost through excretion and evaporation.
• Dehydration is when the body loses more water then it takes in.– Mild dehydration can interfere with
mental and physical performance.– Severe dehydration can have very
serious consequences, including death.– Caffeine depletes water from the body!!
