1. Fats and Proteins
Unit 4 Nutrition

2. Fats Recommended 20 to 35 percent come from fat.
The good: supply body with energy, form cells, and maintain body temp.
The bad: Has twice as many calories as carbohydrates per gram, cause heart disease, and weight gain.

3. Unsaturated (most are liquid at room temp.)
Vegetable oils, nuts, and seeds
Monounsaturated (olive oil, peanuts and canola oil) and polyunsaturated (corn and soybean oil)
Easily broken down
Can help fight heart disease

4. Saturated (most are solid at room temp.)
Meat, whole milk, butter, ice cream.
Cause weight gain, increased blood cholesterol levels and risk of heart disease.

5. Cholesterol (found in animal products)
Liver makes it, so not necessary
Meat, egg yoke, fish and poultry
Too much of cholesterol and fat = plaque build-up and heart attack
LDL and HDL

6. Trans Fats (Made when hydrogen is added to fat in vegetable oils)
Stay fresh longer than unsaturated fats.
Margarine, chips, french fries, doughnuts and cookies.
Few of the benefits of unsaturated and many of risks of saturated.
Raise LDL (bad) and lower HDL (good).

7. Protein Can serve as source of energy
Growth and Repair of body tissues.
Amino acid chains form protein.
Body breaks down into amino acid
20 different types (9 essential amino acids and 11 nonessential amino acids)
Ex: meats, eggs, poultry, milk, nuts, dried beans and dried peas.

8. 9 essential amino acids can’t be made by the body.
11 nonessential amino acids can be made by the body.
Complete proteins
Contain all 9 essential amino acids.
Meat and fish.
Incomplete proteins
Don’t contain the 9 essential amino acids.
Plants, grains, beans and vegetables.

9. Thinking about it all… Carbohydrates Fats Protein
45 to 65 percent of daily caloric intake
Fats
20 to 35 percent of daily caloric intake
Protein
10 to 35 percent of daily caloric intake

10. Activity Time
Create a brochure describing 3 benefits of each (carb’s, fats and proteins) and draw 1 food that each nutrient is found in. Create a cover for your brochure and three panels. Include color and creativity.
