Words to Know Nutrition – is the science that studies
how the body makes use of the substances in food and how and why people eat the way they do
Diet – Everything you regularly eat and drink
Nutrients – the substances in food that your body needs
Carbohydrates- are the main source of energy for your body
![Page 5: Nutrition and Fitness](https://reader035.vdocuments.net/reader035/viewer/2022062521/568156dc550346895dc4834e/html5/thumbnails/5.jpg)
Words to Know Proteins – are essential for the
growth and repair of body cells Fats – Another source of energy Vitamins – substances that help
regulate body functions (A,D,E,K) Mineral - elements that help your
body work properly (Calcium and Phosphorus)

A Balanced DietAlthough everyone follows a diet, not all diets are healthy
A healthy diet provides all the nutrients you need
To have a healthy, balanced diet, you must eat the right amounts of six types of nutrients
![Page 8: Nutrition and Fitness](https://reader035.vdocuments.net/reader035/viewer/2022062521/568156dc550346895dc4834e/html5/thumbnails/8.jpg)
The six Categories of Nutrients Carbohydrates- main source of
energy for your body. Simple carbohydrates, or sugars, are found in fruits, milk, and table sugar
Starchy foods such as bread, rice, and pasta contain complex carbohydrates
The fiber in starchy foods helps the digestion process
![Page 9: Nutrition and Fitness](https://reader035.vdocuments.net/reader035/viewer/2022062521/568156dc550346895dc4834e/html5/thumbnails/9.jpg)
The six Categories of Nutrients Proteins – essential for the growth and
repair of body cells Proteins are made up of amino acids, which
are chains of building blocks Your body can produce some amino acids.
Others called essential amino acids must come from the foods you eat
Foods that contain all the essential amino acids are called complete proteins
![Page 10: Nutrition and Fitness](https://reader035.vdocuments.net/reader035/viewer/2022062521/568156dc550346895dc4834e/html5/thumbnails/10.jpg)
Proteins Continued Foods that contain only some of the essential amino acids are called incomplete proteins
![Page 11: Nutrition and Fitness](https://reader035.vdocuments.net/reader035/viewer/2022062521/568156dc550346895dc4834e/html5/thumbnails/11.jpg)
The six Categories of Nutrients Fats – are another source of energy
Your body depends on fat cells for energy storage and protection against temperature changes
Fats carry certain vitamins in your blood stream and help keep your skin healthy
Nevertheless, eating too much fat will cause weight gain and may lead to other health problems
![Page 12: Nutrition and Fitness](https://reader035.vdocuments.net/reader035/viewer/2022062521/568156dc550346895dc4834e/html5/thumbnails/12.jpg)

Food Guide Pyramid Continued The size of each section in the pyramid
corresponds roughly to the amount of that kind of food you should eat daily

Teens should get three full servings from the milk, yogurt, and cheese group daily Nutrients from this group are important to
growth

Food Guide Pyramid ContinuedThe fats, oils, and sweets section is the smallest These foods provide calories, but offer few nutritional benefits
There is not a RDA for this group
