1 Nutrition and Your Body Health Education -TPI-

2 Content Goal: TSWBAT: educate and advocate better nutrition and increased physical activity through demonstrating an understanding of key concepts related to proper nutrition and maintenance of healthy body weight. Content Objectives: TSWBAT:  describe factors that influence eating behaviors and food choices.  define each of the six main classes of nutrients, their functions in the body, and the sources for obtaining them.  explain the health risks related to overweight, obesity, underweight, and certain disordered eating habits.  summarize basic nutritional principles including the "food guide pyramid" and the “7 dietary guidelines.”  break down food labels and compare and contrast between multiple labels.  evaluate the effectiveness and safety of fad diets  point out misleading health claims and beneficial possibilities of health foods and supplements.  discuss special problems related to the American lifestyle and nutrition.  identify the impact of food on overall health.

3 Today n Lifestyle or Non- Communicable diseases n Nutrition & Diet n Sedentary n ^ Smoking, Alcohol “Back Then” n Infectious or Communicable Diseases n Environmental Conditions n Lack of Resources

4 Life Expectancy n “It would be the first time in the modern era we would actually see one generation experiencing a shorter life span than the previous generation." n The drop will occur when the current generation of obese and overweight adults reaches old age, and will worsen when obese and overweight children hit middle age.


6 An American Issue


8 Factors Influencing Food Choices

9 Why do we really eat today? n Hunger vs. Appetite n Hunger: a natural drive to prevent starvation. n Appetite: a desire for food n Want vs. Need n Emotional Eating

10 Combating Emotional Eating n Learn to recognize true hunger. n Know your triggers. n Look elsewhere for comfort. n Don't keep unhealthy foods around. n Snack healthy. n Eat a balanced diet. n Exercise regularly and get adequate rest.


12 SUPER-SIZE ME Wrap-Up n Super-Size Me assignment n Graded Discussion n Fast Food Analysis Webquest

13 SuperSize Me Graded Discussion (Out of 5) n 1 person at a time (Facilitator?) +1 Point n Everyone speaks once (1 Freebie) + 1 Point n (At least) 5 subtopics related to nutrition + 1 Point n Time (At least 15 minutes) & No lapse in speaking (>15 seconds) + 1 Point n Side chatter (nada) +1 Point

14 McDonald's to Offer Nutrition Labels

15 Does the ‘typical’ American utilize/understand the Dietary Guidelines?

16 Starting Simple: Recommendations n Where should your calories come from

17 Calories… (=Unit of Energy) n 1,600 calories is about right for many sedentary women and some older adults. n 2,200 calories is about right for most children, teenage girls, active women, and many sedentary men. Women who are pregnant or breastfeeding may need somewhat more. n 2,800 calories is about right for teenage boys, many active men, and some very active women.

18 The Basics….

19 Practical vs. Technical n Should you know: –Fat grams –Sodium –Protein –Calories –Etc. Per day?

20 The Key to Nutrition Nutrient Density: n High Nutrients per Caloric Content n VERSUS: Empty Calories The Key to proper nutrition is: n Variety n Balance n Moderation (What does this mean?)

21 There are no “good” foods or “bad” foods n Foods are not good nor bad n Moderation and variety are key to enjoying all foods n Anytime foods n Sometimes foods n Seldom foods n Too many seldom foods and few anytime foods = a bad diet

22 10 Tips for Healthy Eating n Eat a variety of nutrient-rich foods n Enjoy plenty of whole grains, fruits and vegetables n Maintain a healthy weight n Eat moderate portions n Eat smaller regular meals vs. one or two large meals. n Reduce, don't eliminate certain foods n Know your diet pitfalls. n Make changes gradually. n Remember, foods are not good or bad.

23 Pyramids Guide Our Choices

24 Understanding proper portion sizes is an important part of maintaining healthy nutrition. But many of us really don’t know how big our portions should be.


26 Pick Your Favorite Snack 14 25 36 Discover your own Snack Food Personality Profile

27 n (1) Potato chips: "Potato chip lovers are successful, high achievers who enjoy the rewards and trimmings of their success—both in business and in family life." n (2) Tortilla chips: "Perfectionists in regards to their own actions and to the community at large, people who crave tortilla chips are humanitarians who are often distressed by the inequities and injustices of society." n (3) Snack crackers: "Contemplative and thoughtful, people who prefer snack crackers base their decisions on logic rather than emotions." n (4) Pretzels: "Lively and energetic, pretzel fans seek novelty and thrive in the world of abstract concepts. They often lose interest in mundane, day-to-day routines." n (5) Cheese curls: "Formal, conscientious and always proper, the cheese curl lover can be described with one word—integrity. They will always maintain moral high ground with their family, work and romantic partners." n (6) Meat snacks: "Gregarious and social, those who reach for a savory bag of pork rinds or crave beef jerky and other meat snacks are often the life of the party. They are loyal and true friends who can always be trusted.“ n Did you notice that with this test everyone is a winner? That’s because the research for this personality test was "conducted on behalf of the Snack Food Association and the National Potato Promotion Board."

28 Essential Nutrients n Needed by the body; must be present in the diet –Nonessential- your body can manufacture from other nutrients in the diet n Requirements depend on age, sex, growth status, body size, genetics n Requirements influenced by conditions like pregnancy, breastfeeding, illnesses, drug use, and others

29 THE BASICS:.. n Nutrients Define: Substances in food that… n Build and repair cells. n Regulate body processes. n Provide energy. n Nutrients that have Calories: –Proteins 1 Gram = 4 calories –Carbohydrates 1 Gram = 4 calories –Fats 1 Gram = 9 calories

30  Vitamins  Minerals  Water  Protein  Carbohydrates  Fats Starches Cellulose

31 Sources of Energy in the Diet

32 Carbohydrates-4 cal/g n Are the body’s main source of energy (FUNCTION). n Supply fiber, and aid in digestion of fat. n Are broken down into sugars, starches and fiber.

33 Complex Carbohydrates “Slow-Burning” n Are starches. n Provide vitamins, minerals and fiber as well as carbohydrates. n Include dry beans, starchy vegetables like potatoes, corn, and peas; rice, pasta, oatmeal; bread and cereal.

34 Refined Carbs (Fast Burning): n The calorie content of refined white flour actually increases about 10% because of everything else that has been taken out. n An average of 66% of the B vitamins have been removed. n An average of 70% of all minerals have been removed. n 79% of the fiber has been removed. n An average of 19% of the protein has been removed.

35 Low0 – 55 Moderate56 – 69 High 70 or more A scale that ranks carbohydrates by how much they raise blood glucose levels compared to a reference food. What is the glycemic index? Glycemic Index (GI)

36 Glycemic Index (GI): Sample Graphs Adapted from Good Carbs Bad Carbs Reprinted courtesy of Marlowe & Company.

42 Carbohydrates Review n Function n Fast Burning n Slow Burning n How can you tell??? n Type 1 Vs. Type 2 Diabetes n Demo n Article Ave 20 males 34

43 Protein-4 cal/g n 2 major functions (working proteins & structural) n Working-enzymes, antibodies, hormones, O carriers n Structural-tendons, ligaments, core of bone/teeth n Supplies energy when there is not enough fat or carbohydrate for the body to use.

44 Protein n Composed of amino acids (building blocks). n There are 22 amino acids; –9 of which the body cannot manufacture (ESSENTIAL), – and 13 which the body can produce (NON- ESSENTIAL).

45 Protein n Complete proteins contain all 9 essential amino acids. They are foods which come from animals. n This includes steak,pork,chicken, turkey, fish, eggs and dairy products.

46 Protein n Incomplete proteins lack one or more of the essential amino acids. n This includes pinto beans, kidney beans,split peas, lentils, rice, corn tortillas, peanut butter, and nuts.


48 Protein Recommendations n The RDA for protein is 0.8 grams per kilogram of body weight per day (.364 gr/lb/bw/d).1 n That's about 9 grams of protein for every 20 pounds n RDA levels may be inadequate and may impede recovery or limit muscle growth for athletes? –Endurance athletes 1.2 to 1.4 grams per kg b/w. –Strength and power athletes 1.4 to 1.8 grams per kilogram of body weight per day.

49 Fats, Cooking Oils and Fatty Acids n Fat should account for 30% or less of the calories consumed daily n Saturated fats accounting for no more than 10% of the total fat intake. n Function: –Maintain body temperature –Protect body tissues and organs –Plays an essential role in carrying the four fat- soluble vitamins: A, D, E, and K. Excess calories from protein and carbohydrates are converted to and stored as fat. Even if you are eating mostly "fat free" foods, excess consumption will result in additional body fat.

50 Fats-9 cal/g Fats Saturated Animal Products Solid @ Room Temp Increase Cholesterol Red Meats, Butter Unsaturated Plant Products Decrease Cholesterol olive oil, canola oil, peanut oil Liquid @ Room Temp

51 Animal vs. Plant Foods and Heart Disease in Pictures-- n …….Saturated Unsaturated……

52 Trans Fat n Trans fat is a type of processed fat that does not occur in nature n Also called hydrogenated or partially hydrogenated fat/oil n Used in baked goods like doughnuts, breads, crackers, potato chips, cookies and many other processed food products like margarine and salad dressings. n Research suggests a correlation between diets high in trans fats and diseases like atherosclerosis and coronary heart disease

53 Fat & the Body n The fats can be stored in any cell in the body but are mostly stored beneath our skin. n These fat tissues are called adipose tissue where the fat cells join together, depositing under our skin to make us fat. –In women, the adipose tissue is mostly found in the hips, buttocks, and thighs; –while in men, it is found in the abdomen causing big bellies.

54 Vitamins n Major Functions –Convert fat and carbohydrate into energy. –Work as catalysts for chemical processes in the body- jump start reactions. –Assist in the formation of tissue and bone.

55 Vitamins n Fat Soluble vitamins are carried in fat and can be stored in your body. n It is possible to overdose on fat soluble vitamins. n Water soluble vitamins are carried in water and cannot be stored in your body. n Excess water soluble vitamins are disposed of in the urine.
