Name ________________________ Period ____ Table ____ Score: _____/16 Protein 1/2 point each) Describe the function of protein. Tell sources of complete and incomplete proteins. Tell how to complete incomplete proteins. Give tips for selecting proteins. The function of protein is to build and repair body cells. Every cell in the human body needs protein. List 5 kinds of cells you will need protein to help build: Proteins are made of building blocks called amino acids. When you eat a protein, you take apart its amino acids, and rearrange them to build the new proteins you need. There are some amino acids you can make, but some you cannot make, and must get from the proteins you eat. The amino acids you must get from proteins you eat are called __________________ amino acids Protein comes from animal foods, or from the seeds of plants Proteins that come from animal foods are complete. They provide al l the essential amino acids. Draw 3 foods that are complete proteins. Proteins that come from the seed part of the plant are incomplete. Draw 3 incomplete proteins. Complete with: Peanut Butter Includes Legumes ( peanuts ) 2 complementary proteins will complete each other. Grains Nuts & Seeds To be able to use incomplete proteins, you need to combine them with another protein that provides the missing amino acids. You can combine foods from the grain group with legumes (things that grow in a pod, like beans or peanuts) or nuts from the meat group. You can combine nuts with legumes. Or you can complete any incomplete protein with a complete protein. (Pairs would need to be eaten the same day to be able to work together.) For each of the incomplete proteins you drew above, write in another incomplete protein that would complete it. Americans generally get plenty of protein. Our problem is to make sure we are making healthy choices for our protein foods. Here is advice from the Dietary Guidelines for Americans on how to select and handle your protein foods. Check off which choices help you follow that advice. The Dietary Guidelines Say: Choose lean meats. Keep it lean (Prepare it in a way that is low in fat.). Vary your protein choices. Keep it safe to eat. So Which Would Be a Better Choice? (check off your choice) 80% lean ground beef Use Nutrition Facts to choose foods low in saturated fat Cook meat with all fat on. or or 95% lean ground beef Pick meats with plenty of saturated fat. Trim away excess fat before cooking. Cook chicken with skin on. Broil or roast meats Don’t add breading or batter Serve without high fat gravy Stick with red meats. Eat only animal proteins. Pull skin off chicken. or Fry meats or Bread or batter fish and meats or Serve with high fat gravy or Choose fish more often or Have beans as main dish or sometimes Store raw meats with other or Separate raw meats from foods foods that won’t be cooked. Take your best guess about or Use a meat thermometer when meats are cooked enough Defrost meats in refrigerator, or Defrost meats at room in cold water, or in microwave. temperature. Refrigerate leftovers in 2 hours or Refrigerate leftovers in less or less. than 4 hours. Note: meat and poultry should NOT be rinsed before cooking. Brian is making dinner for his girlfriend tonight. He stopped on the way home from his classes, and picked up flowers, fresh fish, and other ingredients for the dinner. Then he went shopping for a new shirt, got a hair-cut, and picked up his dry cleaning. At home, he put the fish on the cutting board with his salad ingredients, set the table, and went to take a short nap. He woke up rested and ready to start. He dipped the fish in batter and deep-fried it. He made salad, baked potatoes, and put a frozen pie in the oven to bake. He served the fish with sliced lemon, instead of a fatty sauce. After dinner he put all the leftovers in the refrigerator quickly, before leaving to go dancing.
