Objective 2: Be able to identify where you could obtain the 9 essential amino acids. 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. Objective 3: Give an example of how to make incomplete proteins complete by combining foods. Objective 4: Analyze and evaluate if the use of rBHT (growth hormone) and/or use of antibiotics should be used in our animals (food supply) Objective 4: Analyze and evaluate if the use of rBHT (growth hormone) and/or use of antibiotics should be used in our animals (food supply)

4. Amino Acids Protein is made up of chains called, Amino Acids Protein is made up of chains called, Amino Acids Your body can manufacture all but 9 of the 20 different amino acids that make up proteins. 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 These 9 amino acids are known as Essential Amino Acids These 9 you have to get from foods. These 9 you have to get from foods. So where do we get them? So where do we get them?

5. Complete Proteins Complete Proteins Complete Proteins Contain adequate amounts of all nine essential amino acids. Contain adequate amounts of all nine essential amino acids. Found in animal products Found in animal products Fish Fish Meat Meat Poultry Poultry Eggs Eggs Dairy Products; milk, cheese, yogurt Dairy Products; milk, cheese, yogurt Soy (is a versatile bean) is a good Soy (is a versatile bean) is a good source of protein for vegetarians or vegans source of protein for vegetarians or vegans

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