  1. Unit 4 Nutrition & Physical Activity

  2. Bell Ringer • On a half sheet of paper, tell me what the most effective lesson has been so far, what the least effective lesson has been so far, and why you feel that way. Turn it in when you are done. (you won’t hurt my feelings ^__^) • When you are done, STUDY FOR YOUR ASSESSMENT! • Functions of body systems • Identifying parts of the reproductive system • Some major milestones in the stages of life

  3. 2005 Dietary Guidelines • Adequate Nutrients Within Calorie Needs • Consume a variety of nutrient-dense foods and beverages • Meet recommended intakes • Weight Management • Balance calories in and calories expended • Physical Activity • Engage in regular physical activity and reduce sedentary activities

  4. 2005 Dietary Guidelines • Food Groups to Encourage • Consume a variety of fruits and veggies daily • Choose whole grains • Choose low or reduced fat dairy products • Fats • Avoid saturated/trans fat • Keep fat intake to 20-35% of caloric intake • Carbohydrates • Choose fiber-rich fruits/veggies/whole grains • Limit intake of foods with added sugars

  5. 2005 Dietary Guidelines • Sodium & Potassium • Consume less than 2.3K mg (about 1 tsp) of salt a day • Consume potassium rich foods • Alcoholic Beverages • Limit intake to 1 drink a day for females and 2 drinks a day for males • Some people should avoid alcohol all together • Food Safety • Clean hands, surfaces, and foods properly • Be mindful of appropriate temperatures for food

  7. What are Nutrients? • Chemicals found in foods that are critical to human growth and function. • Carbohydrates • Fats/Oils • Proteins • Vitamins • Minerals • Water

  8. Energy • Carbohydrates, fats, and proteins are macronutrients that provide energy. • Macronutrients: Nutrients that our bodies need in relatively large amounts to support normal function and health. • While alcohol is a chemical found in food and does provide energy, it is not technically considered a nutrient because it does not support the regulation of body functions.

  9. Carbohydrates • The primary fuel source for our bodies, particularly the brain and physical exercise • Many are fiber rich • Sources • Grains, vegetables, fruits, legumes, seeds, nuts, dairy

  10. Fats & Oils • An important energy source for our bodies at rest and during low-intensity exercise • Yield more energy per gram than carbs • Sources • Butter, lard, vegetable oil, olive oil

  11. Proteins • A macronutrient that the body uses to build tissue and regulate body functions • Not a primary source of energy • Sources • Meats, dairy, nuts, seeds, legumes, vegetables, whole grains

  12. Micronutrients • Nutrients needed in small amounts to support normal health & body functions

  13. Vitamins • Micronutrients that contain carbon and assist us in regulating the processes of our bodies • Can be water soluble or fat soluble • Sources • Animal products, nuts, seeds, fruits, veggies

  14. Minerals • Micronutrients that do not contain carbon, are not broken down during digestion and absorption, and are not destroyed by heat or light • Assist in the regulation of many body processes and are either major minerals or trace minerals • Sources • Meats, dairy, fruits, vegetables, nuts

  15. Water • Inorganic nutrient that is vital for survival • Keeps cellular fluid balanced • Regulates nerve impulse, muscle contractions, nutrient transport, & excretion of waste • Sources • Pure form, juices, soups, fruits, veggies

  16. Why do we eat what we eat? • Personal Preference • Hunger • Culture/Tradition • Social Interactions • Availability, Convenience, & Economy • Emotional Comfort • Values • Body Image • Advertising

  17. Read the label! • Break into groups, read the ingredients labels and try figure out the food product is.

  18. Snickers Bar • milk chocolate (sugar, cocoa butter, chocolate, skimmed milk, lactose, milkfat, soy lecithin, artificial flavor), peanuts, corn syrup, sugar, skimmed milk, butter, partially hydrogenated soybean oil, lactose (a milk product), salt, egg whites and artificial flavor

  19. Twinkie • Enriched Bleached Wheat Flour [Flour, Reduced Iron, B Vitamins (Niacin, Thiamine Mononitrate (B1), Riboflavin (B2), Folic Acid)], Corn Syrup, Sugar, High Fructose Corn Syrup, Water, Partially Hydrogenated Vegetable and/or Animal Shortening (Soybean, Cottonseed and/or Canola Oil, Beef Fat), Whole Eggs, Dextrose. Contains 2% or Less of: Modified Corn Starch, Glucose, Leavenings (Sodium Acid Pyrophosphate, Baking Soda, Monocalcium Phosphate), Sweet Dairy Whey, Soy Protein Isolate, Calcium and Sodium Caseinate, Salt, Mono and Diglycerides, Polysorbate 60, Soy Lecithin, Soy Flour, Cornstarch, Cellulose Gum, Sodium StearoylLactylate, Natural and Artificial Flavors, Sorbic Acid (to Retain Freshness), Yellow 5, Red 40.

  20. Cool Whip • water, hydrogenated vegetable oil, high fructose corn syrup, corn syrup, skim milk, light cream, and less than 2% sodium caseinate (a milk derivative), natural and artificial flavor, xanthan and guar gums, polysorbate 60, sorbitanmonostearate, and beta carotene (as a coloring).

  21. BK Milkshake • milkfat and nonfat milk, sugar, sweet whey, high fructose corn syrup, corn syrup, natural and artificial vanilla flavour, guar gum, mono and diglycerides, cellulose gum, sodium phosphate, carrageenan and natural flavours from plant sources

  23. Daily Bell Ringer • On a half sheet of paper, List 5 things that affect why we eat what we eat. Turn in when done. • Come see me for your Assessment 3’s.

  24. What Is a Healthful Diet? • Adequate • Provides enough energy, nutrients, & fiber • Moderate • Provides the right amount of food • Balanced • Contains proper combinations of nutrients • Varied • Contains different types of foods

  25. How do we know what to eat?

  26. Food Pyramid

  27. ChooseMyPlate.gov

  28. Can you plan for a day? • http://www.mypyramidtracker.gov/planner/index.aspx • http://www.choosemyplate.gov/tipsresources/index.html

  29. But I Don’t Have Time! • Prepare ingredients ahead of time • Make extra of some foods to use in other dishes (like pasta or rice) • Save leftovers: Cook once, Eat Twice! • Fast dishes: • Sandwiches, wraps, stir-fry, beans, fruit, yogurt, pasta, rice

  30. Tips for Eating Out • Order water, unsweetened tea, or low fat/fat free milk • Order whole-wheat bread for sandwiches/toast • Get a salad as an appetizer and ask for dressing on the side • Choose small or medium portions • Share food with a friend, get a “to-go” box before you start eating and put half away, or resign from the “clean your plate club” : ) • Avoid all-you-can-eat buffets

  31. Over-nutrition • Excess nutrient and energy intake over time than is needed for normal growth • Results from eating too much food or taking too many supplements • Can lead to obesity or vitamin toxicity in fat soluble vitamins

  32. Under-nutrition • Insufficient food intake • Includes being underweight for one’s age, short for one’s age, dangerously thin, or being deficient in vitamins and/or minerals • Leads to the inability to maintain natural body capacities • Increases possibility of infectious disease
