1 Nutrition: The Nutrients

2

3 1. Nutrients- Compounds in food that the body requires for proper growth, maintenance, and functioning. 2. Nutrient Deficiencies- Too little of one or more nutrients in the diet. 3. Malnutrition- Results of the body of poor nutrition. 4. Undernutrition- Too little food energy or too few nutrients in the diet to prevent disease or to promote growth. 5. Overnutrition- Too much food energy or excess nutrients to the degree of causing disease or increasing risk of disease. 6. Carbohydrate- Class of nutrients made of sugars; these nutrients include sugar, starch, and fiber. 7. Fat- Class of nutrients that doesnt mix with water. Fat is mostly made up of fatty acids, which provide energy to the body. 8. Protein- Protein Class of nutrients that builds body tissues and supplies energy. Made up of amino acids. 9. Vitamins- Essential nutrients that do not yield energy, but that are required for growth and proper functioning of the body. 10. Minerals- Elements of the Earth needed in the diet, which perform many functions in body tissues. 11. Energy- Capacity to do work or produce heat 12. Glucose- Bodys blood sugar; a simple carbohydrate.

4 1. Fatty Acids- Simple forms of fat that supply energy fuel for most of the bodys cells. 2. Amino Acids- Simple forms of fat of protein normally used to build tissues or, under some conditions, burned for energy 3. Toxin- A poison 4. Calories- Units used to measure energy. Calories indicate how much energy can be used by the body or stored in body fat. 5. Glycogen- Form in which the liver and muscles store glucose. 6. Hypothalamus- Brain regulatory system. 7. Balanced Meal- Meal with foods to provide the right amounts of carbohydrate, fat, and protein. 8. Digestion- Breaking down of food into nutrients the body can use. 9. Starch- Carbohydrate, main food energy source for human beings. 10. Fiber- indigestible substances in foods, made mostly of carbohydrate. 11.

7 Benefits of Nutrition

8 Good nutrition helps people stay strong, fit and healthy. Overnutrition and undernutrition are equally dangerous to your health. Undernutrition is the lack of nutrients your body needs to survive. Overnutrition on the other hand is too many nutrients or foods. Too help with your bodies nutrition you can follow these dietary guidelines

9 1. Eat a variety of foods. 2. Balance the food you eat with physical activity. 3. Choose a diet with plenty of grain products, vegetables and fruits 4. Choose a diet low in fat, saturated fat and cholesterol 5. Choose a diet moderate in sugars 6. Choose a diet moderate in salt and sodium.

10

11 1: Write a sentence using each term. 2: Explain the difference between over and under nutrition. 3: List three benefits of good nutrition. 4: List the 6 dietary guidelines for Americans

12 How to choose Nutritious Foods

13 The best possible way to avoid over eating calories and still meet your bodies nutrient needs is to follow the food guide pyramid. Have 6 servings of bread, cereal, rice, and pasta group. Three from the vegetables group. Two servings from the fruit group. Two servings from the diary group. Two servings from the meat, poultry, fish, dry beans, eggs, and nuts group.

14

15 1: Write a sentence using each term. 2: What is the best possible way to meet all the bodies nutritious needs? 3: How can you avoid consuming large amounts of calories and still meet the bodies nutritious needs? 4: From which food group should you eat 6 servings?

16 Energy from Food

17 Calories are used to measure energy. Energy is the ability to produce heat Your body draws glucose from the calories you do not use. Glucose is the bodies sugar storage. When you are hungry your appetite sends out the hunger signal. Protein is your bodies blood sugar. Carbohydrates are simple forms of protein.

18 The number of calories effects how much glucose. If u eat too many, your body will store more than needed. The body taps into the stored glucose if you do not get enough from the foods you eat. A balanced meal is the best source of energy for the body because you get all the needed nutrients and plenty of calories without over doing it.

19

20 What are the units used to measure energy in food ? What is the bodies storage form of sugar called? The (blank) sends out the hunger signal. (blank) is the bodies blood sugar. The capacity to produce heat or do work is (blank). (blank) are simple forms of protein.

21 Explain how the number of calories in a food reflects its fattening power. How does the body meet its glucose need if you have not eaten? Why is a balanced meal considered the best source of energy for the body?

22 The Carbohydrates

23 Fibers are not a source of energy for the body. Your body is unable to digest them. Which if you eat too much of can lead to constipation. Also trying to pass the hard stools created by constipation may lead to hemorrhoids. Foods that contribute many calories but not many nutrients contain fats. But fibers arent always bad, just too many can hurt, if you limit your fibers it helps strengthen your digestive tract.

24

25 1: Explain the relationship between fiber and composition. 2: What does fiber have to do with hemorrhoids? 3: Foods that contribute a lot of calories but insufficient nutrients contain (blank). 4: Explain the effect of starchy foods on brain functioning. 5: Why is it beneficial to obtain adequate amounts of fiber in your diet?

26 6: What danger is there in consuming large amounts of sugar? 7: Give 2 examples of each. Foods in carbohydrates, foods in fiber, foods in high sugar.

27 The Fats

28 There are two different types of fats. Saturated and Unsaturated fat. Saturated fats come from animals and are associated with the heart. Unsaturated come from plants are a associated with arteries. Your body digests these and you get your nutrients from them. Nutrients are measured in grams. The man function of fat in the body is to provide glucose.

29 Three steps you can take to control the amount of fat in your diet. Choose lean meats with no visible fats. Dont choose fried foods. Trim all the fat you can see on your meat.

32 Protein

33 Proteins main use in the body is to supply amino acids. Meats and Wheat are good sources of protein. One sign of protein deficiencies are lack of essential amino acids and bone loss.

34

35 1: Write a sentence using each glossary term. 2: What is the function of protein in the body? 3: What foods are the best sources of protein? 4: What are some signs of protein deficiency?

36 Vitamins

37 Two classes of vitamins are Water soluble and fat soluble. Water soluble are able to dissolve in water. Fat are able to dissolve in fat. Powdered pill that contains only vitamins is call a vitamin pill. Deficiency is a lack a of a essential vitamin. If you lack vitamin A you will become blind at night if this continues you could be permanently blinded. Thiamin helps the body get energy from other nutrients.

40 Minerals

41 Osteoporosis is a disease that causes bone loss. Osteoporosis is caused is caused by lack of protein. Anemia is a reduced number of blood cells. This is caused by lack of electrolytes. Electrolytes main function is to keep the fluids running in your body.
