MyPlate icon?

Fruits

• 1 cup of fruit or 100% fruit juice= 1/ 2 cup dried fruit or 1 cup fresh fruit

• low in fat, sodium, and calories

• cholesterol free

• Sources of potassium, dietary fiber, vitamin C and folate

• Potassium helps maintain healthy blood pressure

• Fiber helps reduce blood cholesterol levels

• Vitamin C helps repair tissue, helps heal cuts, and keeps teeth and gums healthy

Vegetables

• Any vegetable or 100% vegetable juice counts in this group

• 1 cup vegetables= 1 cup vegetable juice; 2 cups raw leafy greens; 1 cup cooked vegetables

• 5 subgroups of vegetables o Dark-green o Starchy o Red and orange o Beans and peas o Other

• Low in fat, calories and cholesterol free

• Good source of fiber, folate, Vitamin A(eye and skin health) and C (aids in iron absorption)

Grain

• Grain = wheat, rice, oats, oatmeal, barley, etc.

• Grain products= bread, pasta, grits, etc.

• 2 subgroups of grain- (1) whole [contain entire grain kernel] and (2) refined

[milled and processed]

• Make ½ of your grains whole

• 1 ounce of grains = 1 slice of bread; 1 cup cereal; ½ cup cooked rice or pasta

• Source of fiber and B vitamins (metabolism) and minerals (iron [ carries oxygen in the blood], magnesium [ building bones and releasing energy from muscles] and selenium [protects against cell oxidation] )

Protein

• Meat, poultry, seafood, beans, peas, eggs, soy, nuts, and seeds

• 1 ounce protein= 1 ounce meat, fish, or poultry; ¼ cup cooked beans; 1 egg, 1 tablespoon peanut butter; ½ ounce nuts or seed

• Calcium helps build strong bones and teeth

Fats and Oils

• Canola oil; olive oil; etc.

• Most oils contain monounsaturated and polyunsaturated fats

• Saturated fats - Have no double bonds in chemical structure and are saturated with hydrogens; often solid at room temperature; ex.

Butter

• Unsaturated fats - Have double bonds in chemical structure; often liquid at room temperature; ex. Most oils

• Trans fats= partially hydrolyzed ( hydrogens added to chemical structure) oils

• Provide essential nutrients such as essential fatty acids
