Page 16: Essential Nutrients

UnSaturated Fat

• Contain UnSaturated Fatty Acids

• Comes only from Plant Products (Excludes Coconut & Palm Oil)

Page 17: Essential Nutrients

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.

Page 18: Essential Nutrients

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.

Page 19: Essential Nutrients

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.

Page 20: Essential Nutrients

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!!
