Nutritionally balanced diet provides adequate protein. Protein supplements are rarely needed by healthy people.
Vegetarians are able to get adequate amounts of essential amino by eating a variety of plant proteins.
The amount of recommended daily protein depends upon your age and health. Two to three servings of protein-rich food will meet the daily needs of most adults.
The following are the recommended serving sizes for protein:
2 to 3 ounces of cooked lean meat, poultry, or fish (a portion about the size of a deck of playing cards)
1/2 cup of cooked dried beans
1 egg white, 2 tablespoons of peanut butter, or 1 ounce of cheese
Select lean meat, poultry without skin, fish, and dried beans, and low-fat or fat-free dairy products often.
