Adults in the U.S. are encouraged to get 10% to 35% of their day's calories from protein foods. That's about 46 grams of protein for women, and 56 grams of protein for men. It's not hard to get this amount if you eat two to three servings of protein-rich foods a day, according to the CDC. 1  A small 3-ounce piece of meat has about 21 grams of protein. A typical 8-ounce piece of meat could have over 50 grams of protein.  One 8-ounce container of yogurt has about 11 grams of protein.
Teenage girls between the ages of 14 and 18 require 46 grams of protein daily, while same-age boys need 52 grams. Protein for Adults Adult women between the ages of 19 and 70+ require 46 grams of protein, the same amount needed during adolescence. Same-age adult men need 56 grams of protein, 4 grams more than they required during teenage years. Getting Enough Protein. To make sure you get the requisite grams of protein you need daily, calculate the amount found in specific servings of protein-rich foods. For example, a cup of milk contains 8 grams of protein, while a 3-oz. piece of meat contains around 21, says the CDC.
