Why is protein so important to your diet? Protein is a building block for bones, muscle, skin and blood as well as providing the body with energy. Adequate amounts of protein help heal wounds faster. Protein helps maintain muscle mass and protein foods provide B vitamins, iron, zinc and magnesium.

How much protein do you need? Protein needs are calculated as a percentage of your total calorie intake. Protein needs can be shown in “grams” or ounce equivalents. Here’s how to calculate protein needs in grams:

Example: If you eat 2,000 calories a day, 10 to 20 percent of those calories should come from protein.
1. Using 20 percent of calories from protein, we do this calculation: 0.2 x 2,000 = 400 calories
2. Protein contains 4 calories per gram. 400 calories ÷ 4 calories/gram = 100 grams of protein
3. Divide protein into meals/snacks throughout the day. 100 grams of protein ÷ 3 meals/day = 30 to 35 grams protein per meal, on average

What is a protein food? According to MyPlate.gov, meat, poultry, seafood, beans and peas, eggs, processed soy products, nuts and seeds are considered part of the Protein Foods Group. Protein needs are shown as “ounce equivalents” on MyPlate.gov.

One ounce equivalent = 1 ounce of meat, poultry or fish (about the size of four dice), ¼ cup cooked beans (about the size of a golf ball), 1 egg, 1 tablespoon of peanut butter or ½ ounce of nuts or seeds .

Remember: Excess protein above calorie needs is likely to contribute to weight gain. Dollar for dollar, whole foods are a better buy than supplements because whole foods contain a larger variety of nutrients and other needed ingredients such as antioxidants.

Enjoy different kinds of protein throughout the day -
Eggs (6 grams protein / large egg) -
Meat, poultry and fish (about 21 grams protein / 3-ounce piece – about the size of a deck of cards) -
Milk and milk products (8 grams protein /1 cup milk) -
Nuts and seeds (about 5 grams protein /1 ounce raw nuts – a small handful) -
Tofu (13 grams protein/½ cup tofu) -
Legumes, dry beans and peas (8 grams protein / ½ cup beans)
