Protein has many different roles in the body. Protein is involved in the growth and maintenance of tissues such as our skin, bone and muscles. It’s also involved in hormone processes, our immune system, and occasionally our body will use protein for energy.
Protein comes in a complete form, mainly found in animal products, such as your meat, poultry, dairy, fish. Protein can also be found in plant sources as well, but it’s not considered complete. So, if you are going to rely solely on vegetables and plants for your protein source, you do want to make sure that it’s going to complement and ensure you’re getting all the amino acids you need for good health.
If you have more questions about protein and a healthy diet, contact your local dietitian or medical professional.
