Stopping to enjoy a single-serving cup of yogurt midway through your afternoon or starting your day with a breakfast consisting of yogurt and fruit provides a healthy boost of protein. Although the specific protein content of yogurt varies significantly, every type of yogurt contains protein. If you're watching your weight, pick the unsweetened varieties, which don't contain added sugar.
Fat Content Plays a Role
The fat content of your serving of yogurt influences the amount of protein. The higher the fat, the lower the protein content, according to the U.S. Department of Agriculture. A 6-ounce serving of plain yogurt made with skim milk has virtually no fat and contains about 9.7 grams of protein. Low-fat plain yogurt, which has about 2.6 grams of fat per 6-ounce container, has about 8.9 grams of protein. Yogurt made with whole milk, which has 5.5 grams of fat per 6-ounce serving, has 5.9 grams of protein.
Greek Packs a Bigger Protein Punch
A 6-ounce serving of nonfat fruit yogurt contains about 7.5 grams of protein, according to the USDA. If you opt for Greek yogurt, expect to consume a greater amount of protein. The USDA reports that a 6-ounce container of nonfat Greek yogurt has 17.3 grams of protein. Regardless of the flavor or whether the product is labeled as nonfat or low in fat, traditional yogurt contains significantly less protein than Greek yogurt. When shopping for yogurt, compare the protein content by checking the nutrition information panel on your favorite brands.
