Examples of complete proteins are cheese, fish, meat, and milk. Frequently, foods from plant origin lack one or more of the needed amino acids and are therefore incomplete. Proteins are an important part of your red blood cells. The basic units of all proteins are amino acids, which are components of hormones. These hormones control body functions such as growth and development.
Amino acids are components of antibodies, which are substances that help the body fight disease.
To ensure your daily need for iron, zinc, and other minerals packaged in protein foods, it is recommended that you have two servings of protein foods every day. The best way to accomplish this is to mix and match animal and vegetable protein foods. Dairy products also provide you with protein and many other essential nutrients, but be very careful as your diet should not include too much diary and meat. You need to find a balance for your protein intake. The balance is 0.8 grams per kg of ideal body weight for adults.
