2. Nutrients Have Class Too! Ms. Makuta

3. Nutrients Have Class Too! • Objectives: • The students will explain the six major nutrients. • The students will explain the breakdown of foods and absorption of nutrients by the body. • Vocabulary: • Nutrition • Nutrients • Carbohydrates • Fats • Proteins • Vitamins • Minerals • Water • Nutrient Deficiency

4. What is nutrition? • Nutrition is the study of how your body uses the food you eat.

5. What is a nutrient? • A nutrient is a chemical substance in the body that helps maintain the body.

6. The Six Classes of Nutrients • Your body needs over 50 different nutrients which can be divided into 6 classes: • Carbohydrates • Fats • Proteins • Vitamins • Minerals • Water

7. Carbohydrates • Functions • Provides body main source of energy • Produces glucose – used immediately or stored • Provide bulk • Helps the body digest fats • Sources: • Sugars - honey, jam • Starch sources - breads, cereals, pasta • Fiber sources - fruits, vegetables, whole grains

8. Carbohydrates • Types • Simple Carbohydrates/Sugars • Include sugars found naturally in foods such as fruits, vegetables, and milk products. • Simple carbohydrates also include sugars added during food processing and refining. • Complex Carbohydrates • Starch and dietary fiber. • Starch must be broken down through digestion before your body can use it as a glucose source.

9. Carbohydrates

10. Fats • Functions • Provides energy • Carries fat- soluble vitamins (A, D, E, and K) • Protects vital organs and provides insulation • Provides essential fatty acids • Types • Fatty Acids • Cholesterol Fats are compounds of many types of fatty acids and a body chemical called glycerol.

11. Fats • Types • Fatty Acids • Saturated Fat – found in animal and dairy products • Raises LDL • Polyunsaturated – found in olive peanut oils • Decreases LDL • Monounsaturated – found in corn and vegetable oils • Decreases LDL • Increases HDL • Cholesterol • Low density lipoproteins – LDL - ”bad cholesterol” • High density lipoproteins – HDL - ”good cholesterol”

12. Some “Fat” Examples • Cheese • Butter • Nuts • Meats • Dressings • Chocolate What other fat examples can you identify?

13. Proteins • Functions • Build and repair tissues • Helps the body to make important substances • Regulate body processes • Supply energy • Types • Complete: contains adequate amounts of all essential amino acids • Incomplete: Lacks some amino acids

14. Proteins Sources • Complete • Meat • Milk • Eggs • Fish • Incomplete • Nuts • Legumes Complex carbohydrates are broken down into glucose more slowly than simple carbohydrates. This provide the body with a gradual steady stream of energy throughout the day.

15. Think Nutritionally • Are following all sources of energy, carbohydrates, proteins, and fats? • True – thumbs up • False – thumbs down

16. Motivational Quote Nutrition and Wellness Challenge This week let’s increase our cardiovascular activity. Try to go for a walk, run, bike ride, or etc at least twice.

17. In your Journal/NotebookFirst, write down all the food and beverage items you consumed.Next, identify any physical activity you engaged in. Tuesday, September 10, 2013

18. Think Nutritiously… • Red meat is an example of which form of energy? • Fat • Carbohydrate • Protein • Is eating red meat healthy? • Let’s find out….

19. Vitamins • Can be divided into two main categories • Fat-soluble vitamins • dissolve in fats • can be stored in fatty tissues of the body • Water-soluble vitamins • dissolve in water • are not stored in the body

20. Fat-Soluble Vitamins • Fat-soluble vitamins are stored in the body's cells and are not excreted as easily as water-soluble vitamins. • They do not need to be consumed as often as water-soluble vitamins, although adequate amounts are needed. • If you take too much of a fat-soluble vitamin, it could become toxic. • Your body is especially sensitive to too much vitamin A from animal sources (retinol) and too much vitamin D. • A balanced diet usually provides enough fat-soluble vitamins.

23. Mushroom Diet Has anyone every heard of this new diet trend?

24. Water-Soluble Vitamins • Water-soluble vitamins travel freely through the body, and excess amounts usually are excreted by the kidneys. • The body needs water-soluble vitamins in frequent, small doses. • These vitamins are not as likely as fat-soluble vitamins to reach toxic levels.

25. Water-Soluble Vitamins

26. Minerals • Minerals can also be divided into two categories: • Macrominerals are needed in amounts of 100 mg or more per day. • Trace elements are needed in amounts less than 100 mg per day.

27. Macrominerals

28. Trace Minerals

29. Water • Functions • Aids digestion and cell growth and maintenance • Facilitates chemical reactions • Lubricates joints and cells • Regulates body temperature • Overall well-being • Sources • Water • Milk • Fruits and Vegetables • Other Liquids • Some Foods

30. Nutrient DeficienciesNot getting enough nutrients can lead to deficiency diseases.

31. Excess Nutrients • As with everything, too much of any one thing is not good for you and the same thing goes for nutrients. • Excess energy nutrients - carbohydrates, fats, and proteins - can lead to unhealthy weight gain. • Excesses of some vitamins and minerals can lead to toxicity (poisoning) and other complications.
