31. Nutrition

32. Nutrition: Words to Know • NUTRITION - is the science that studies how body makes use of food • DIET - is everything you eat and drink • NUTRIENTS - are the substances in food • CALORIES – See the next slide

33. What’s the deal with CALORIES? • A calorie is a unit of energy produced by food and used by the body • There are 3500 calories in a pound • Fat: 1 gram = 9 calories • Protein: 1 gram = 4 calories • Carbohydrates: 1 gram = 4 calories

34. 6 Essential Nutrients • Substance that must be obtained from the diet because the body cannot make it in sufficient quantity to meet its need: • Carbohydrates • Protein • Fat • Vitamins • Minerals • Water

35. CARBOHYDRATES • Your body's main source of energy. • Most calories (55-60%) should come from carbohydrates. • Carbohydrates can be grouped into two categories: Simple and Complex. • Simple Carbohydrates = Sugars • Complex Carbohydrates = Starch & Dietary fiber.  

36. Main Sources of Carbohydrates • Grain products • Breads • Cereals • Pasta • Rice • Fruits • Vegetables

37. PROTEIN • Needed for growth; building and repair or body tissues • The “building blocks” of the body • Secondary energy source

38. Main Sources of Protein • 2 Kinds of Proteins:

39. FAT • 2 Types: Saturated and Unsaturated • Maintains skin and hair • Cushions vital organs • Provides insulation • Production and absorption of certain vitamins and hormones.

40. Main Sources of Fat • Animal-based foods • Meats • Milk products • Oils • Nuts • Peanut butter

41. VITAMINS • Help to regulate chemical reactions in the body.   • Vitamins cannot be made in the body, we must obtain them through the diet.     • Vitamins are best consumed through a varied diet rather than as a supplement because there is little chance of taking too high a dose. • Vitamins come from a variety of sources • Eat a assorted & colorful diet!

42. MINERALS • Minerals are components of foods that are involved in many body functions.    • Minerals are not a source of energy and are best obtained through a varied diet rather than supplements. • Minerals come from a variety of foods

43. WATER • Water helps to control our body temperature, carries nutrients and waste products from our cells, and is needed for our cells to function.  • Most of our body weight (60-70%) is made up of water.   • Drink at least 64 oz. per day • How do you know if you are drinking enough water? • Clear urine

44. Food Labels • Serving Size – The amount of food, such as 1 cup of cereal, 2 cookies, or 12 pretzels. It tells you how many nutrients are in that amount of food. • What is the serving size for this food? • Answer - ½ Cup • How many serving are in this container? • Answer - 4 Servings • How many calories are in 1 serving of this food? • Answer – 90 Calories • How many calories are in 3 serving of this food? • Answer – 270 Calories • Using the Percent Daily Value • Low = 5% or less of the Daily Value • Moderate = 6%-19% of the Daily Value • High = 20% or more of the Daily Value

45. Nutrition Facts Quiz • Directions: Analyze the nutritional value of this food. • ALL nutrients with a percent daily value should be listed in the chartList both the nutrient AND the percentage

46. McDonald's Big Mac

47. Build a Healthy Plate Featuring MyPlate and the 2010 Dietary Guidelines

48. What is MyPlate? • MyPlate is a tool designed to remind Americans to eat healthfully • MyPlate illustrates the five food groups using a familiar mealtime visual, a place setting
