2 Protein Greek word that means “Of Prime Importance”
It is the chief component of EVERY living Cell, of body tissue, of body fluids, and of muscles

3 Protein Proteins provide 4 calories per gram.
The main function of protein is to build and repair body tissues. If carbohydrates and fat are not available, your body will use protein. Is this a good thing? You must eat protein daily to replace the wear and tear on the body tissues. We get most of our protein from the Meats and Beans food group. We should eat 5 ½ oz. daily from the Meats and Beans food group.

4 Must be supplied daily Constantly needed to replace wear and tear of tissue and keep up protein concentration in the blood serum

5 Fats and Carbs cannot replace Protein
Needed to replace wear and tear of tissue and keep up protein concentration in the blood Excess protein, once converted to energy, cannot convert back to protein, that is why we need it every day.

6 Amino Acids Amino acids are the “building blocks” of protein.
There are 9 essential amino acids. Essential means that your body MUST have them.

7 The best sources of protein
HIGH = Milk and Meat group MEDIUM = Grains and Vegetables LOW = Fruit

8 Complete Proteins Complete proteins contain all 9 of the essential amino acids. Complete proteins come from animal food sources. Tofu (from soybeans) is the only complete protein from a plant source.

9 Incomplete Proteins Incomplete proteins do NOT contain all of the essential amino acids. Incomplete proteins come from plant food sources. Examples of incomplete proteins could be: Grains Beans Nuts/Seeds Rice Wheat

10 Combining Proteins Incomplete proteins can be combined to create a complete protein. Examples include: Beans and Rice Peanut Butter and Whole Wheat Toast Bean Soup with a Wheat Roll

11 Eat a variety of food Make certain the body gets all the essential amino acids. Make protein complete Combine plant and animal food Combining plant protein from variety of cereals and grains


13 Protein needs influenced by
Age Body Size Quality of the proteins Physical state of the person 5 ounces per day=Girls 6 ½ oz per day= Boys

14 Higher income = more protein eaten Find specific recommendation
Your weight / 2.2 = ? x .8 =?? g/day

15 Excessive Protein May do more harm than good
Not necessary to eat a lot Obesity Kidney malfunction

16 Insufficient Protein Lower one’s resistance to disease,
Muscle deterioration Anemia Hair, skin, and nails are affected Mental illness can develop Edema: accumulation of fluid Stunt growth Not common in U.S.

17 Protein Deficiency Disease MARASMUS
“Starvation” Lack of food Thin Wasting away Wise Adults (looks old)


19 TYPES OF VEGETARIAN VEGANS = Most severe, No Animal products
Lacto vegetarians = will eat DAIRY Lacto-ovo vegetarians = Will eat DAIRY and EGGS

20 Advantages of Vegetarians
Lower weight Lower cholesterol Lower fat and calories intake Lower risk of diabetes, obesity, and some cancers

21 Disadvantages High fiber causes lower mineral absorption
May Stunt Growth Be careful with forcing kids to be vegetarians

22 Supplements High toxicity to liver Muscle work builds protein,
Supplements DO NOT
