1. NUTRITION- Science or study of food and the ways in which the body uses food Nutrient- a substance in food that provides energy or helps form body tissues and that are necessary for life and growth

2. 6 Classes of Nutrients 1.Carbohydrates 2.Fats 3.Proteins 4.Vitamins 5.Minerals 6.Water

4. Carbohydrates SIMPLE CARBOHYDRATES Simple carbohydrates are quick energy sources, but they do not usually supply any other nutrients or fiber. SUGARS - Glucose is the major kind of simple sugar. Glucose is the basic source of energy for all living things. Glucose supplies the body with quick energy. It occurs naturally in some fruits and vegetables and is also produced in the body by breaking down other foods into glucose. Sucrose: commonly known as table sugar, beet sugar, or cane sugar. Sucrose occurs in many fruits and some vegetables. Fructose: known as fruit sugar. Most plants contain fructose, especially fruits and saps. Glucose: sometimes known as blood sugar, sometimes as grape sugar. Nearly all plant foods contain glucose. Lactose: commonly known as milk sugar. It is the principal carbohydrate found in milk.

5. COMPLEX CARBOHYDRATES Complex carbohydrates often supply energy and other nutrients and fiber that the body needs. They are a better choice. STARCH - in the body breaks down into simple sugars. The body has to break down all sugar/starch into glucose to use it. Starch supplies the body with long, sustained energy. DIETARY FIBER - which is found in plant cells. Because it is tough and stringy, it does not break down completely in the body. Fiber is essential for regulating the body. It is the non-digestible part of plants. Glycogen- Made in the body: stored in the muscle and liver of humans and animals. Can be broken down to provide a quick source of glucose

6. FAT Lipids= Fat ( another name ) Class of energy giving nutrients: also the main form of energy storage in the body. Fat is a nutrient that provides the body with 9 calories per gram. Aside from providing energy, it also has some other key functions which include aiding in the absorption of fat soluble vitamins and producing hormones. One of the biggest misconceptions surrounding this nutrient is that eating fat will make you fat. Fat does not make you fat, excess calories is responsible for that.eating fat will make you fat GOOD FATS= Unsaturated, Monounsaturated, Polyunsaturated BAD FATS= Saturated, Trans Fat

7. FAT Saturated vs. Unsaturated Fats Saturated fats are found in animal products and are unhealthy because they generally raise the level of bad cholesterol (LDL) in the body. Sources include dairy products (milk, cheese, butter, ice cream), meats and eggs. Unsaturated fats are found mostly in vegetable products and are healthy because they tend to lower the bad cholesterols (LDL) while raising levels of good cholesterols (HDL). Sources include vegetable oils (olive & canola oil), nuts, seeds and seafood (salmon, tuna, shrimp).

8. Cholesterol Cholesterol is a waxy, fat-like substance that occurs naturally in all parts of the body. Your body needs some cholesterol to work properly. But if you have too much in your blood, it can stick to the walls of your arteries. This is called plaque. Plaque can narrow your arteries or even block them.

9. Good vs. Bad LDL ( BAD )- cholesterol can build up on the walls of your arteries and increase your chances of getting heart disease. That is why LDL cholesterol is referred to as "bad" cholesterol. The lower your LDL cholesterol number, the lower your risk. HDL cholesterol -- "good" cholesterol -- the higher the number, the lower your risk. This is because HDL cholesterol protects against heart disease by taking the "bad" cholesterol out of your blood and keeping it from building up in your arteries.

10. Proteins True or False….? Eating extra protein is important if you want to build bigger muscles. Needed to build and repair body structures and to regulate processes in the body Protein: 1 gram = 4 calories Muscles, skin, hair, and nails are made up of proteins Complete Proteins= Animal proteins such as meat, eggs, and dairy products Incomplete Proteins= Plant Proteins such as veggies, grains.

11. Vitamins Nutrients are needed to maintain health and allow growth. 2 types of Vitamins= 1.Fat Soluble Vitamins- they dissolve in fat, most can be stored in fat tissue and remain in the body for a long time- 4 KINDS 2.Water Soluble Vitamins- used right when they go in the body. Water soluble vitamins aren’t stored in the body well. 9 KINDS -Get a BOOK and write down what these VITAMINS are, foods that have them in it and what it does for our bodies -Page 161 and 162

12. Minerals Class of nutrients that are chemical elements that are needed for certain body processes, such as enzyme activity and bone formation. Examples: Calcium, Sodium (Salt), Copper Go to page 163 Find 13 different Minerals- tell me what foods they are in and what it does for the body

13. WATER- H20 8 - 8 oz. glasses a day= 64 oz. a day Weight loss Water is one of the best tools for weight loss, first of all because it often replaces high-calorie drinks like soda and juice and alcohol with a drink that doesn't have any calories. But it's also a great appetite suppressant, and often when we think we're hungry, we're actually just thirsty. Water has no fat, no calories, no carbs, no sugar. Heart healthy Drinking a good amount of water could lower your risks of a heart attack. A six-year study published in the May 1, 2002 American Journal of Epidemiology found that those who drink more than 5 glasses of water a day were 41% less likely to die from a heart attack during the study period than those who drank less than two glasses. Energy Being dehydrated can sap your energy and make you feel tired --. If you're thirsty, you're already dehydrated -- and this can lead to fatigue, muscle weakness, dizziness and other symptoms. Headache cure Another symptom of dehydration is headaches. In fact, often when we have headaches it's simply a matter of not drinking enough water. There are lots of other causes of headaches of course, but dehydration is a common one. Healthy skin Drinking water can clear up your skin and people often report a healthy glow after drinking water. It won't happen overnight, of course, but just a week of drinking a healthy amount of water can have good effects on your skin. Digestive problems Our digestive systems need a good amount of water to digest food properly. Cleansing Water is used by the body to help flush out toxins and waste products from the body. Cancer risk Related to the digestive system item above, drinking a healthy amount of water has also been found to reduce the risk of colon cancer by 45%. Drinking lots of water can also reduce the risk of bladder cancer by 50% and potentially reduce the risk of breast cancer. Better exercise Being dehydrated can severely hamper your athletic activities, slowing you down and making it harder to lift weights. Exercise requires additional water, so be sure to hydrate before, during and after exercise.

14. Dehydration is DANGEROUS Dry mouth. Lowered blood pressure, headaches, and dizziness. Muscle fatigue. Lean muscle tissue contains about 75 percent water, so when the body’s short on water, muscles are more easily fatigued.muscle tissue Dry, cool skin. Thirst. Feeling lethargic and irritable. Lack of urine. – Color of Urine…….
