Source of protein

 a healthful eating pattern includes a variety of foods containing protein. Both animal and plant foods can be excellent sources of protein.

The guidelines classify the following foods as protein foods:

• seafood
• lean meats and poultry
• eggs
• legumes, which include beans and peas
• nuts
• seeds
• soy products

Dairy products, such as milk, cheese, and yogurt, also contain protein. Whole grains and vegetables contain some protein, but generally less than other sources.

Animal products tend to contain higher amounts of protein than plant foods, so people following a vegetarian diet or a vegan diet may need to plan their meals to ensure they meet their protein needs
