  1. Nutrition:Protein Chapter 5 Lesson 3

  2. Analyzing Protein • Objective 1: Identify the role of protein in your body • Objective 2: Be able to identify where you could obtain the 9 essential amino acids • Objective 3: Give an example of how to make incomplete proteins complete by combining foods

  3. Review from Lesson 2 • What are simple carbohydrates? • Sugars; glucose, fructose, lactose • Examples? • Fruits, Milk, Cake, Candy, Pop • What are complex carbohydrates? • Starches • Examples? • Whole grains, seeds, nuts, legumes, tubers • The body must break down__________ carbohydrates into ___________carbohydrates before it can use them for energy. • Complex/simple

  4. Protein, What is it? How does it work? • Protein • Nutrients that help build and maintain body cells and tissues • Made up of chains called, Amino Acids • Your body can manufacture all but 9 of the 20 different amino acids that make up proteins. • These 9 amino acids are known as Essential Amino Acids • So where do we get them?

  5. Complete Proteins • Complete Proteins • Contain adequate amounts of all nine essential amino acids. • Found in animal products • Fish • Meat • Poultry • Eggs • Dairy Products; milk, cheese, yogurt

  6. Controversial Topics • What other mammal (besides humans) needs to drink milk from a cow (other than a baby calf)? • Is rHBT (growth hormone) safe? • http://www.consumerhealth.org/articles/display.cfm?ID=19991128221446 • Should animals be regularly fed antibiotics? • How can this have an affect on us?

  8. Vegetarians • Do not eat meat • There is a difference between vegetarians and vegans. What is it? • May have a challenge getting protein, so how do they? • Eggs, Milk, Cheese, Yogurt • Beans, legumes, grains, nuts, seeds • Combining foods carefully is the key • Ex: Legumes + Grains • Ex: Nuts + Seeds

  9. Incomplete Proteins • Incomplete Proteins • Lack one or more of the essential amino acids • Sources • Beans, peas, nuts, and whole grains • If you were to combine peanut butter and bread, that would give you a complete protein • You don’t have to combine the incomplete proteins in one meal, you just need to eat them over the course of the day!

  10. Role of Proteins • Proteins have many functions including; • During major growth periods such as; adolescence, puberty, & pregnancy, the body builds new cells and tissues from the amino acids in proteins. • Throughout your life your body replaces damaged or worn-out cells by making new ones from protein.

  11. Role of Proteins • Your body also produces enzymes, hormones and antibodies from proteins. • Proteins help supply your body with energy, even though they are not the main source. • Proteins, like carbs, provide 4 calories per every 1 gram. • Excess protein is converted to body fat
