Proteins
Fats
Vitamins
Minerals
Water
Guidelines for Good Nutrition

Balance Food and Physical Activity
Getting the Nutrition Facts

7. What Nutrients Do You Need?
Your body needs the nutrients in food to perform the activities of daily life.
nutrients Substances in foods that your body needs to grow, have energy, and stay healthy
Just as a car needs fuel in order to run, your body needs nutrients.
Six Types of Nutrients
Carbohydrates
Proteins
Fats
Vitamins
Minerals
Water

8. Two Types of Carbohydrates
Your body uses carbohydrates as its main source of energy.
carbohydrates The starches and sugars found in foods
Foods containing carbohydrates include:
Baked potato
Bread
Noodles
Fruits
Vegetables
When the energy from carbohydrates is not used right away, it is stored in the body as fat.
Simple carbohydrates are sugars and occur naturally in foods
Complex carbohydrates are starches, which are found in foods such as potatoes, beans, and whole-grain cereals.
The body must break down carbohydrates into sugars in order to use them.
Two Types of Carbohydrates
Simple
Complex

9. Carbohydrates
Some fiber is found in the tough, course part of plant foods such as the bran in whole-grain wheat and oats.
fiber A complex carbohydrate that the body cannot break down for energy

10. Proteins are made up of compounds called amino acids.
proteins The nutrient group used to build and repair cells
Complete proteins contain all the essential, or necessary amino acids and are found in meat, fish, eggs, dairy products, and soybeans.
Incomplete proteins (with the exception of soybeans) lack at least one of the essential amino acids. However, you can get all the amino acids you need by combining certain plant foods.
Two Types of Proteins
Complete
Incomplete

11. Fats help build and maintain your cell membranes
fats Nutrients that promote normal growth, give you energy, and keep your skin healthy
Fats carry vitamins A, D, E, and K to all parts of the body.

12. Fats
Saturated fats are found in meat, poultry, butter, and other dairy products.
saturated fats Fats that are usually solid at room temperature
Over time, eating too many saturated fats can increase the risk of heart disease and other diseases.

13. Two Types of Cholesterol
Fats
Your body makes two types of cholesterol.
cholesterol The waxy, fat-like substance that the body uses to build cells and make other substances
HDL cholesterol is known as “good” cholesterol because it protects against heart disease.
LDL cholesterol is known as “bad” cholesterol because it sticks to the walls of blood vessels, which can cause heart disease.
Eating a lot of saturated fats can raise blood levels of LDL cholesterol.
Dietary sources of cholesterol include meat, some seafood, whole or reduced-fat milk, many cheeses, and butter.
Two Types of Cholesterol
HDL (“good”)
LDL (“bad”)

14. Fats
Blood levels of LDL cholesterol can rise if you eat too much trans fat, or trans fatty acids.
Oil is turned into a solid so that it can be used for such foods products as stick margarine. This process keeps oils fresh longer.
trans fatty acids A kind of fat formed when hydrogen is added to vegetable oil during processing

15. Vitamins are either fat-soluble or water soluble.
Some vitamins help your body fight disease, while others help your body produce energy.
vitamins Compounds that help to regulate body processes
Fat-soluble vitamins include A, D, E, and K. They can be stored in the body.
Water-soluble vitamins include C and B. Your body needs a fresh supply of water soluble vitamins each day.
Ensure that you are getting enough vitamins by eating a variety of foods.
Vitamins are either fat-soluble or water soluble.

16. Minerals are important to your health.
minerals Substances the body uses to form healthy bones and teeth, keep blood healthy, and keep the heart and other organs working properly

17. Minerals Mineral What It Does Where to Find It Iron
Helps make red blood cells
Meat, poultry, beans
Calcium
Magnesium
Phosphorus
Helps build teeth and bones and keeps them strong
Milk, cheese, and other dairy products
Potassium Sodium Chloride
Helps maintain the body’s fluid balance
Bananas, cantaloupe, fish, vegetables, meats such as chicken and turkey

18. A person can only live about one week without water.
Carries nutrients to your cells
Helps you digest food
Helps your body remove waste
Helps regulate your body temperature
Water
When you perspire heavily, you need to increase the amount of water you drink.
Most foods contain water, but the best sources of water are plain water, milk, and juice. Coffee and sodas are not good sources of water.

19. Guidelines for Good Nutrition
The U.S. Department of Agriculture (USDA) and the Department of Health and Human Services have developed the Dietary Guidelines for Americans.
The Dietary Guidelines for Americans provide scientifically valid information about healthy eating and active living.

20. Make Smart Food Choices
Eat a variety of nutritious foods every day.
Choose to eat fruit instead of drinking fruit juices.
Vary your vegetables and eat more of them.
Half of the grains you eat should be whole grains.
Eat enough calcium-rich foods.
Here are some tips for making smart food choices. Following these tips will give your body the balanced nutrition it needs.
Eat a variety of protein-rich foods.
Go easy on foods that are high in saturated fats.
When you eat meat, choose lean cuts and dishes that are baked, broiled, or grilled.

21. Avoid Too Much Sugar and Salt
Too Much Salt…
Fills you up an makes you less likely to eat healthy foods
Promotes tooth decay
Is stored as fat, causing weight gain
Can increase blood pressure
Table salt contains a mineral called sodium that helps regulate blood pressure.
You can avoid eating too much salt by cutting down on salty snacks and not sprinkling salt on your food at mealtimes. Use the information on food labels to choose foods lower in sodium.

22. Balance Food and Physical Activity
Try to match how physically active you are with the amount of food you eat.
To balance your weight with how you eat, be sure to fit physical activity into your life.
Aim for the recommended 60 minutes of moderate physical activity each day.

23. Getting the Nutrition Facts
Almost all packaged foods have a Nutrition Facts label, which contains facts about the nutritional value of one serving of the product. This information will help you make good choices about what foods to include in your eating plan.
Keep in mind that a package many contain more than one serving.
The label shows percentages of Daily Value (DV) for key nutrients.
Look for foods containing 20 percent or more of the needed vitamins, minerals, and fiber.
Foods with 5 percent or less of fat, cholesterol, and sodium are good choices.
Pay attention to the additives in each packaged food. Food additives have been approved for human consumption, but the long-term effects are not fully understood.

24. Reading Ingredients Lists
Keep this in mind: Corn syrup, dextrose, and sucrose are all types of sugar. If they are among the first three items in a product’s ingredients list, the amount of added sugar is high.

25. What I Learned Vocabulary What is fiber? Lesson 1 Review
Fiber is a complex carbohydrate that the body cannot break down or use for energy.

26. Lesson 1 Review
What I Learned
Identify Which nutrient group is preferred by the body as a source of energy?
The body prefers carbohydrates as a source of energy.

27. What I Learned Explain How do vitamins help your body? Lesson 1 Review
Vitamins regulate body processes, help fight disease, and produce energy.

28. Lesson 1 Review

List Name the six nutrient groups that your body needs to be healthy.
The six nutrient groups are carbohydrates, proteins, fats, vitamins, minerals, and water

29. Lesson 1 Review
Thinking Critically
Apply Your friend eats a lot of snacks that are high in fat and sugar. She also says she doesn’t like fruits or vegetables. How could you influence your peer to make more healthful food choices?
Sample answer: Tell her too much fat can increase the risk of heart attacks and strokes, too much sugar can cause tooth decay, both can cause weight gain.

30. Lesson 1 Review

Sample answer: to help people make good choices about what foods to eat
