LT #8- I can explain how protein and fats benefit the body.
Your body uses about 20 amino acids that are found in foods. You produce, or synthesize, all but 9 of the amino acids.
Essential amino acids: Nine amino acids the body must get from food.
Complete proteins: proteins from animal sources because they contain all 9 essential amino acids.
Examples of plant-based foods that are rich in protein:
Teen boys ages 14-18 should consume about 52 grams of protein per day, and teen girls ages 14-18 need 46 grams per day.
Types of Fats
- Unsaturated fats- Vegetable oils, nuts, and seeds tend to contain larger amounts of unsaturated fats. Eating unsaturated fats in moderate amounts may lower your risk of heart disease.
- Saturated fats- found mostly in animal-based food such as meat and many dairy products. Consuming too many saturated fats may increase your risk of heart disease.
- Trans fat- These fats are formed by a process called hydrogenation, which causes vegetable oil to harden. As it hardens, the fats become more saturated. Can be found in stick margarine, many snack foods, and packed baked goods, such as cookies and crackers. Trans fat can raise your total blood cholesterol level, which increases your risk for heart disease.
The essential fatty acids are also important to brain development, blood clotting, and controlling inflammation. They also help maintain healthy skin and hair.
adipose tissue- stored fat that provides insulation for the body.
Nutrition experts recommend that teens consume less than 25-35 percent of their calories from fats because of the health risk associated with fats.
