Fat: Energy-giving nutrients that are also the main form of energy storage in the body. 3. Protein: Amino acids that repair and build body structures such as muscles.  Does Not Provide Energy:  Vitamins, Minerals, and Water

8. Balanced Diet Keeps You Healthy  Too little food: weight loss, poor growth, and possible death.  Too much food: Excess body fat, heart disease, high blood pressure,  Diseases caused by poor nutrition: Obesity, heart disease, osteoporosis, cancer, and diabetes.

9. Your Body and Food  How does the consumption of food affect your body  Provides fuel  Chemical process of food to keep you alive & active (Metabolism)  Every piece of food is an energy source  These energy sources are measured in calories 1. Carbohydrates & Protein-4 calories per gram 2. Fat-9 calories per gram

10. Carbohydrates Simple:Complex: sugarStarch Fruit /Juicepotatoes Milk *Beans and peas CandyGrains such as rice sodaCorn Cakesbread NO NUTRIENTS in these foodsCONTAINS NUTRIENTS

11. Simple Carbs  Sugars:  Are found naturally in some foods and added to some  Refined Sugars:  Are added to other foods to make sweet 1. Candy 2. Cake 3. Soda

12. Complex Carbs  Starches:  Are broken down by the body into sugars  Can be used by the body for energy.  Most starches come from: 1. Plants 2. Starchy vegetables (potatoes) 3. Legumes (beans and peas) 4. Grains (rice, corn, and wheat)

13. Carbohydrates continued…  Glycogen:  Quick energy reserve (storage)  If becomes full, it will be converted into body fat  Fiber:  Cannot be digested but is good for intestines and colon.  Provides little energy  Cannot be digested by humans 1. Soluble fiber traps and remove cholesterol 2. Insoluble fiber helps with removal of waste

14. Fats  What is Fat?  Essential Nutrient  Need it for your body to function properly  Gives texture, flavor, aroma, satisfying feeling  25-35 percent of total calorie intake for teens  Eating too much Fat or wrong kinds:  Increase weight gain  Risk of Heart disease  Risk of some cancers

15. Fats  Saturated Fat: Milk, butter, ice cream,  Leads to obesity  Unsaturated Fat: olive oil, canola oil, peanut oil, flower oil, soybean oil  Can protect from heart disease  Trans fats, by product a. May increase the risk of heart disease b. Manufactured butter substitute

16. Cholesterol  What is cholesterol?  Found only in human and animal tissue.  Also made in the body naturally  Type of steroid  Needed for production of; 1. Vitamin D 2. Cell membranes 3. Hormones 4. Bile which aids in digestion

17. Cholesterol  LDL (Bad)  Too much cholesterol (LDL) can cause Plak to form on the walls of blood vessels  Can cause Heart Attacks due to oxygen restriction  HDL (Good)  Are linked to a reduced risk of developing heart disease

18. Proteins  What is a Protein?  Repairs the body and helps create new cells.  Needed to form hormones, enzymes, antibodies  Can be stored as fat if overconsumption occurs  Amino Acid Molecules  (11) essential amino acids made in the body naturally  (9) essential amino acids must come from our diet

19. Proteins  Complete Proteins: Meat, eggs, and dairy.  Incomplete Proteins: Beans, grains, and vegetables.  Both are necessary in a healthy diet. 10-35% of calories should come from proteins.

20. Exit Slip:  On a sheet of paper make two columns. Then label one column simple carbs and the other complex.  Now think about the last two meals you ate. Then list each food that you consumed in the appropriate column. You may need to break your meal down. For example, if you had a piece of cheese pizza you would need to list the cheese, and bread separately.  Now analyze your list and see if most of your food choices fall into a certain category. Discuss with your elbow partner your findings.
