Vegetarian Diets

Eggs can be an important source of complete protein in diets that omit meats. One egg equals one ounce of lean meat, poultry, fish or seafood. Since an egg contains all the essential amino acids in proportion to human needs in addition to vitamin B12, a nutrient not found in vegetarian sources, adding an egg to a vegetarian diet can improve the healthfulness of a vegetarian diet. – See NutrientProteinReference Daily Intakes (RDIs)
