2. LEARNING OBJECTIVES
After completion of this course the Graduates will be
able to:
1. Students will be able to interpret and apply nutrition concepts
to evaluate and improve the nutritional health of individuals
with medical conditions and demonstrate the role of various
nutrients.
2. Students will be able to identify and apply food principles to
food and nutrition systems
3. Use dietary guides for planning balanced diet.
4. Monitor growth with the help of different tools.
5. Demonstrate critical thinking skills and analytical abilities to
identify and solve problems in the nutritional sciences.
5. DEFINITIONS
• Food may also be defined as anything eaten or
drunk, which meets the needs for energy, building,
regulation and protection of the body.
• Nutrition is the study of nutrients in food, and the
relationship between diet, health, and disease.
• Is the process of consuming, absorbing and using
nutrients needed by the body for growth,
development and maintenance of life.
• Nutrition science deals with the role of food
(dietary inputs) in the maintenance of life.
• Human nutrition deals with the provision of
essential nutrients in food that are necessary to
support human life and health.
6. CLASSIFICATION OF FOODS
Classification by origin: -
• Foods of animal origin
• Foods of vegetable origin
Classification by chemical composition:
• Proteins
• Fats
• Carbohydrates
• Vitamins
• Minerals
7. NUTRIENTS
Organic and inorganic complexes contained in
food are called nutrients.
They are broadly divided in to:
Macronutrients:
• Nutrients required in relatively large amounts.
• Provide energy to our bodies
• Carbohydrates, fats and oils, proteins
Micronutrients:
• Nutrients required in smaller amounts.
• Vitamins and minerals
8. Energy From Nutrients
• We measure energy in kilocalories (kcal).
• Kilocalorie: amount of energy required to
raise the temperature of 1g of water by 1o C.
• On food labels “calorie” refers to kilocalories.
10. Food Exchange System
• The food exchange system was created by the
American Dietetic Association and the US
Public Health Services, as a meal planning
guide primarily for diabetics.
• The food exchange system is based on
principles of good nutrition that apply to
everyone. The food exchange system is
updated, as necessary.
12. Food Guide Pyramid
• Foods Split into
6 Groups
• Each group
contains foods
with similar
nutrients and
calories
13. Group 1: Starch Group
One starch exchange =
• 15 g carbohydrate
• 3 g protein
• 0 -1 g fat
• 80 calories
• In general, 1 starch is:
• ½ cup of cooked cereal, grain
• ½ cup of cooked rice or pasta
• 1 oz of a bread product, like 1 slice bread
• ¾ to 1 oz of most snack foods
14. 1/2 Cup of all beans, peas & lentils
• Because these legumes have
such a high protein content,
• Good source of B Vitamin
Crackers and Snacks
• Popcorn 3 cups = 1 exchange
• Potato chips/tortilla chips 10
chips = 1 exchange Rice Cakes
– 4 in across 2 cakes = 1
exchange
• Whole wheat crackers 2-5
crackers (3/4 oz) = 1 exchange
15. Group 2: Vegetables

Fat varies from whole to skim milk products
• Includes... 1 Cup of Milk (8 oz.) or180 grams Yogurt (6
oz.)
• Excludes... While its true that cheese is a dairy
product, we do not include it into this group due to its
high fat content
• (1 tablespoon = 14.3 grams)
20. Group 5: Meats & Substitutes
• primary source of
protein
• Choose lean Meat

Other
• Egg w/yolk 1 egg = 1

1 exchange
• Peanut Butter 1-2 Tbsp = 1

exchange
• Tofu ½ cup = 1 exchange
22. Group 6: Fats

24. Combination Foods List
• Tuna noodle, lasagna, spaghetti with
meatballs, chili with beans 1 cup (8 oz) = 2

• Chicken or tuna salad ½ cup (3 ½ cup) =
½ carbohydrate, 2 proteins, 1 fat
• Pizza, cheese, thin crust ¼ of 12 inch (6
oz) = 2 carbohydrates, 2 meats, 1 fat
26. Portion Size are based on
• Grams of Protein
• Grams of Carbohydrate
• Grams of Fats
• Total number of Calories
• To use the exchange system, Familiarize
yourself with the different food groups and
the amounts indicated in your meal plan.
27. Estimating Portion Size
• ways to estimate portions when you cant
weigh them such as when dining out.
30. It seems small by it self
but we have 6 for our
day ! Here’s what 3
Choices look Its a like...
decent portion for a
meal. Alternatively, Here
is a Small by 1 Choice of
Ground Beef (1 oz.)
itself but remember that
each meal has more
than 1 Choice!
