proteins

Proteins- nutrients that help your body build, repair and maintain it’s tissue.

Examples

Meat

FishEggsMilkBeansNuts

Foods from plants

Amino acids, complete and incomplete proteins

Amino acids- the building blocks in proteins

Essential Amino Acids- Must come from food. Ex- meat, fish, milk, eggs

These contain complete proteins

Complete Proteins- Provide all the amino acids your body needs.

Ex- meat, fish, milk, eggs

Incomplete Proteins- Do not contain all the necessary amino acids

. Ex- Most food from plants, beans, nuts

You can combine different incomplete proteins to create complete proteins

CARBOHYDRATES

Carbohydrates- Provide energy for your body.

Simple Carbohydrates- Natural sugars, such as those found in fruit and milk products.

They enter the blood rapidly

Complex Carbohydrates- Starches

Ex- bread, rice and starchy vegetables

Provide long lasting energy

Preferred to that of sugar in candy & pop

FIBER

Fiber- The part of grains and plant food that your body cannot digest

Helps move food and waste products through your body during digestion and elimination.

a nutrient because it is

NOT

digested and does

NOT

provide energy or materials for growth

Ex- oat bran, wheat bran, beans, peas, nuts, apples, grapes, green vegetables

FATS, SATURATED FATS

Fats- provide energy and help the body use certain

vitamins more

effectively.

Saturated fats- found in many animal foods such as meat and dairy products.

CHOLESTEROL,

UNSATURATED FATS

Cholesterol- a soft, waxy, fat-like material produced by the body.

VITAMINS

Vitamins- Nutrients that help chemical reactions take place in your body.

Make it possible for your body to process proteins, carbs, and fats

Help produce blood cells and certain chemicals.

Fat & water soluble vitamins

Fat soluble vitamins- These can be stored in the body

Ex- A, D, E, and k

Water soluble vitamins- These CANNOT be stored in the body in large amounts.

Your body needs 13 different essential vitamins.

Examples of vitamins

Vitamin function food source

A healthy skin milk, liver
