1 “The Building Blocks of Life” Protein“The Building Blocks of Life”
2 1. Protein has multiple functions First Use: Build and repair body tissueMaintain cell growthFormation of Enzymes and hormonesInsulin and thyroid hormoneFluid BalanceAntibodies
3 Protein also provides energy There are 4 calories per gram of protein.Can take the place of some fat and carbohydrate if they do not supply enough energy.Prevents protein from being used for their other functionsFat and carbohydrate cannot take the place of protein.
4 Minerals in meat (protein) group Iron meat, eggs, seafood, seeds, nuts, whole grains, dark green leafy vegetablescarries oxygen to all body cellsChromium seafood, meats, eggs, nuts, seeds, peanuts, whole grains, bran, wheat germhelps regulate blood sugar levels (helps prevent and treat diabetes)Copper whole grains, liver & organ meats, legumes, wheat germ & branhelps body assimilate iron and form healthy bonesPhosphorus meat, fish, poultry, nuts, bread & cereal, eggshelps in production of energy and activator of B vitamin complexPotassium whole grains, fruits, vegetables, nuts, seeds, meat, fishworks with sodium to normalize flow of body fluidsManganese whole grains, nuts, seeds, legumes,blood sugar regulation, health of tendons and bonesSelenium seafood, meat, liver, nuts, seeds, legumes, wheat germ, branfights free radicals (destructive cells that may be precursors to cancer)Sulfur eggs, garlic, onionspresent in all body tissues. Needed for skin, joints, hairZinc whole grains, meat, fish, dairy, eggs, nuts, seeds,blood sugar, brain, blood, kidneys, nerves, bones, hair, skin, nails, appetite, sense of smell and taste, reproductive organs
5 Fat soluble vitaminsD sunshine, fortified milk, fish and fish oil, egg yolkneeded for strong teeth and bones, helps body use calcium and phosphorus
6 Water soluble vitamins B 1 Thiamin whole grain or enriched bread and cereals, yeast, liver, pork, fish, lean meats, poultry, milkneeded to help convert food to energy by promoting proper use of sugarsB 2 Riboflavin milk, whole-grain breads and cereals, liver, lean meats, eggs, leafy green vegetablesneeded to help body use carbohydrates, proteins, fats—particularly torelease energy to cellsFolic Acid leafy green vegetables, liverNeeded for formation of body proteins and genetic materials for the cell nucleus. Also helps in the use of substances that contain carbon.deficiency during pregnancy leads to increase risk of neural groove defects
7 MORE Water soluble vitamins Niacin eggs, meats, liver, whole-grain breads and cerealNeeded for energy-producing reactions in cells present in all body tissuesB 6 lean meats, leafy green vegetables, whole-grain cerealsNeeded for formation of red blood cells, certain proteins, and use of fats during metabolismB 12 liver, kidneys, fish, milk, animal foods in generalNeeded to build vital genetic substances for cell nucleus and helps in formation of red blood cells. Also helps functioning of nervous systemPantothenic Acid liver, kidneys, whole-grain breads and cereal, nuts, eggs, dark green vegetables, green beansNeeded for metabolism of carbohydrates, proteins, fats, and formation of hormones and nerve regulating substanceBiotin egg yolk, liver, kidneys, dark green vegetables, green beansNeeded for formation of fatty acids and release of energy from carbohydrates
8 Sources of protein Milk Eggs = 6 g of protein Fish Poultry Red Meat ANIMAL SOURCESPLANT SOURCESMilkEggs = 6 g of proteinFishPoultryRed MeatLow fat preparationsDry beans and peasNutsVegetablesGrain Products
9 Must be supplied dailyBoth fat and carbohydrates are stored in the body, but protein is not stored.Consume enough to supply protein needs.Needed especially at breakfast to replenish proteins used for growth and maintenance during the night.
10 Protein needs influenced by AgeBody SizeQuality of the proteinsPhysical state of the personFGP - Most people need 3-6 ounces per day or 2-3 “servings”3 oz = 1 deck of cards
11 Health experts suggest that we get 10-15 percent of our total calories from protein.
12 % of calorie formulaCaloric need x % of nutrient recommended = daily caloric need2,000 calories x 10% (.10) protein = 200 calories from protein2,000 calories x 30% (.30) protein = 600 calories from proteinDivide daily caloric need by / calories per gram200 daily calories / 4 calories per gram = 50 grams protein600 daily calories / 4 calories per gram = 150 grams proteinA 2,000 calorie Protein range for the day is between calories and 50 – 150 grams
13 RECOMMENDED CALORIE AMOUNT CATEGORYCALORIESTeen males, many active men, and very active females.2,800Older children, teen females, active women, and most men.2,200Younger children, women, and most older adults.1,600NOW FIGURE OUT YOURS
14 Excess Protein People can get too much protein in their bodies. Excess amounts of protein are broken down and stored by the body as fat.Healthy people don’t need protein supplements. They get enough from choosing a variety of foods.
15 Amino Acids Building Blocks from which new proteins are made. There are 22 different ones, but 9 are essential for good health.Essential means that we must get it in our diet because our bodies cannot make it.
16 Complete Protein Support growth and maintenance of body tissue. Any food that has all 9 essential amino acids.
17 Complete protein plant sources ANIMAL SOURCESPLANT SOURCESAll animal proteins are classified as complete proteins.The most complete plant protein is Soybean (tofu). Germ of grains
