Slide1

JOURNAL What influences your food choices?? List at least 3 influences (why do you choose the foods you eat?) Slide2

Nutrition - The process in which the body takes in and uses food. Q: How can good nutrition enhance your quality of life and help prevent disease?? A: It provides the calories and nutrients your body needs for maximum energy and wellness.Slide3

Calories - - Units of heat that measure the energy available in foods.One important reason you eat is to take in calories.This energy (from calories) is used by the body and fuels everything you do. Such as: exercising, playing sports, doing homework, and hanging out with friends.Slide4

Nutrients - - Substances in food that your body needs. Nutrients have many important roles:Gives you energyBuilds new tissue and repairs cellsHelps your body process and run smoothly Making healthy food choices lowers your risk of developing many life-threatening conditions such as: heart disease, stroke, cancers, and osteoporosis

(bones become fragile and more likely to break).Slide5

To survive, the human body needs the nutrients found in food. Nutrients are classified into 6 groups: carbohydrates, proteins, fats, vitamins, minerals, and water. Slide6

Carbohydrates -The starches and sugars present in foods. The body’s preferred source of energy (providing 4 calories per gram). Your body uses energy from carbohydrates to perform EVERY task.Carbohydrates are classified as either simple or complex. Slide7

Simple Carbohydrates-- Sugars (found in fruit, milk, and table sugar)Slide8

Complex Carbohydrates - - Starches (found in whole grains, seeds, nuts, beans, potatoes). Slide9

The body must break down complex carbohydrates into simple carbohydrates before it can use them for energy.Slide10

HUH?!?!?Your body converts ALL carbohydrates into glucose.Glucose - a simple sugar that is your body’s main source of energy. If your body does not use the glucose right away it is stored in the liver and muscles as a substance called Glycogen.Slide11

Journal-List 5 healthy foods served in the cafeteria.- List 5 unhealthy foods served in the cafeteria.Slide12

What does your body do when it needs more energy?? - It converts the glycogen back to glucose. Is it possible to take in more carbohydrates than your body can use right away or store as glycogen??? -YES!! When this happens your body converts and stores the excess carbohydrates as…. body fat Slide13

Fiber - - An indigestible complex carbohydrate that is found in the tough, stringy parts of vegetables, fruits, and whole grains. Fiber can’t be digested and used as energy but it helps move waste through the digestive system and helps prevent intestinal problems such as constipation.Slide14

Proteins -- nutrients that help build and maintain body cells and tissues.Slide15

Proteins continued…During the major growth periods (infancy, childhood, adolescence, and pregnancy) the body uses the protein to build new cells and tissues.Throughout your life, the body replaces damaged and worn out cells by making new ones from proteins.Proteins also supply the body with energy, although it is not the body’s main source of energy.Slide16

Proteins continued….Good sources of proteins are animal products: - fish, - meat - poultry - eggs - milk - cheese (comes from milk) - yogurt (comes from milk) Additional sources can be found in: beans, peas, nuts, and whole grains.Slide17

Fats - True or False??Fats are a substance thatshould be eliminated fromour diets.Slide18

FALSE!!!!!! Some fat in the diet is necessary for good health. Slide19

FATS - Nutrients that provide energy and perform many functions for your body.Two types of fats:Saturated = fats that are solid at room temp (found mostly in animal and dairy products).Unsaturated = liquid at room temp (Mainly from plant sources, vegetable oil, avocados, olives.)Which is better for you??????????Slide20

Unsaturated FatFound in vegetable oils, nuts, and seeds.Unsaturated fats have been associated with reduced risk of heart disease.Slide21

Saturated Fat Animal fats, such as lard, and dairy products are HIGH in saturated fat. Chicken & Fish are LOWER in saturated fat. A high intake of saturated fat can increase the risk of heart disease. Slide22

The role of FATS:Fats transport vitamins in your blood to help with growth and healthy skin.Fats also add flavor and texture to foods, and because they take longer to digest, they satisfy hunger longer than other nutrients.Foods high in fats tend to be high in calories.Consuming too much fat increases your risk of weight gain and obesity.Slide23

CholesterolA waxy lipidlike substance that circulates in the blood. What the body makes on its own is used to produce cell membranes, nerve tissue, Vitamin D, produce hormones, and bile (which helps digest fats).Slide24

Cholesterol Continued….Excess cholesterol is deposited in the arteries (which includes HEART ARTERIES!!!) Arteries can become clogged which can increase the risk of heart disease. Question:Is high cholesterol something that is hereditary? YES!!Slide25

Cholesterol continued…You can’t control age and heredity but you can control what you eat.Dietary Cholesterol - cholesterol found inanimal products such as: -egg yolks -meats (esp. organ meats) - high fat milk productsSlide26

Vitamins -- Substances that help regulate many vital body processes, including fighting diseases and producing energy. Slide27

Minerals - - Substances that the body uses to form healthy bones & teeth, keep the blood healthy, and keep the heart and other organs working properly.*The best way to get vitamins & minerals is to choose nutritious foods.Slide28

Water -Vital to EVERY body functionTransports nutrients and oxygen to cells.Helps you digest and absorb food.Removes toxins and other wastes**You need to replace water that your body loses. It is recommended that you drink 8 cups of water a day.Slide29
Slide30

Refer to the worksheet to answer the following questions:What does Vitamin C help promote?Which mineral is found in bananas?What Vitamin is responsible for healthy skin and normal vision? What are 2 food sources this vitamin is found in?What 2 minerals are responsible for maintaining strong bones and teeth?What is folic acid responsible for?Whole grains, breads, and cereals are rich in what?Slide31

Answers:Vitamin C is responsible for healthy teeth, gums, & bones. It also helps heal wounds & fight infections.Potassium is found in bananas.Vitamin A is responsible for healthy skin & normal vision. Found in dark-green leafy vegies, dairy products, eggs, yellow/orange fruits and vegies.Calcium & FluorideFolic acid is responsible for the production and maintenance of new cells.Vitamin B
