Six Types of Nutrients

You need your journal and workbook today.

Food nourishes you with more than 40 different nutrients. These nutrients are grouped into six categories.

-Carbohydrates-Proteins-Fats-Vitamins-Minerals-Water

Eating a variety of foods to provide these nutrients is essential to good health.

Pg. 83

Carbohydrates

Carbohydrates can be either simple or complex.

Simple carbohydrates, or sugars, are found in fruit, milk, and honey. Sugar is also added to candy, cookies, and other foods.

Pg. 83

Complex carbohydrates, or starches, are found in breads, cereals, pasta, rice, potatoes, dry beans, corn, and other starchy vegetables. Complex carbohydrates are also found in whole-grain foods.

Pg. 83

ProteinsProteins are nutrients your body uses to build, repair, and maintain cells and tissues.Foods from animal sources, such as meat, fish, poultry, eggs, milk, and yogurt contain complete proteins. They provide all the essential amino acids.

Pg. 83

Foods from plant sources, such as soybeans, nuts, peas, and dry beans contain incomplete proteins. They lack one or more essential amino acids.

Pg. 84

FatsFats are nutrients that provide energy and perform many functions for your body. They carry fat-soluble vitamins and promote healthy skin and normal growth.

-Saturated fats are fats that are solid at room temperature. They are found mostly in animal and dairy products, such as butter, red meat, cheese, and whole milk.-Unsaturated fats are fats that remain liquid at room temperature. They come mainly from plant sources, such as vegetable oils, nuts, avocados, and olives.

Pg. 84

VitaminsVitamins help your body fight infections, use other nutrients, and perform other tasks.Water-soluble vitamins, such as vitamin C and B vitamins dissolve in water and cannot be stored in your body.

Fat-soluble vitamins, including vitamins A, D, E, and K, dissolve in fat and can be stored in body fat until needed.

Pg. 84

MineralsMinerals such as calcium, phosphorus, and magnesium help build strong bones and teeth.The mineral iron plays a vital role in making red blood cells.

Pg. 84

Where do you get iron from?

Red meat (beef) and spinach. Why is iron important?

Why did Popeye eat spinach?

To be strong…iron helps your red blood cells, which in turn helps to build muscle.

WaterWater is a nutrient that is vital to your life and health.Water transports nutrients through your body, helps you digest food, lubricates your joints, removes wastes, and helps regulate body temperature.

Pg. 85

Most people need to drink at least 2 quarts of water a day. But this can come from the foods you eat, juice, coffee, tea, soda, or anything else that may have water in it. Most of you will receive enough water from the foods you eat throughout the day.

However…You should force yourself to drink water in very hot weather, at high altitudes, or when you exercise.

Thirst and the color of your urine are good indicators of dehydration. That’s our body’s way of telling us, “Hey buddy! We need water!” Pg. 85

Comments…

Of course, there are always exceptions to this rule, if you have a medical condition or some people just need more water than others. Listen to your own body and drink accordingly.

But who told the public that we need to drink 8 glasses of water a day?

The International Bottled Water Association wants you to drink a minimum of 8 eight ounce glasses of water a day. They funded (gave money) research that showed people should consume this much water a day and then had the media publish the study. Why would they do that?

Money. Be aware that many nutritional studies are funded by companies that sell the product they are researching.

Other Substances in Food

Food contains many substances in addition to the major nutrients.

-Fiber: helps move particles through your digestive system.

-Hidden fats: Health experts recommend that no more than 35% of your daily calories come from fat.

-Cholesterol: a waxy substance used by the body to build cells and hormones and to protect nerve fibers.

Pg. 85

Why is fiber important?

Keeps you regular. Or helps you to go to the bathroom. Fiber is basically like a pipe cleaner that cleans out your intestines.

GROSS!!

3 sources of fiber-skins of fruits-skins of veggies-whole grains

Look at your top 5 favorite foods…Figure out which category of nutrients they belong.
