The answer is no. The 2 most popular choices we have for protein are animal and plant. Some common examples of animal protein are: fish, chicken, eggs, pork, and beef. Usually animal sources of protein are considered high quality sources of protein because they contain all 9 essential amino acids. This is important because essential amino acids must be consumed in our diet since our body cannot manufacture them.
Now plant protein is also popular. Some common examples of plant protein are: wheat, rice, peanuts, and oatmeal. For the most part plant proteins are considered low quality protein sources because they do not contain all 9 essential amino acids. However, there are some plant proteins that high quality such as: quinoa, buckwheat, and soy. But there are not as many high-quality plant proteins compared to animal proteins. Therefore, if you are consuming a plant-based diet I would make sure you are getting enough high-quality protein sources. One quick tip to do this is combine a few plant proteins to make these otherwise low-quality sources high quality. For example, if you combine rice and beans together they make the perfect high-quality protein meal. So, just be smart with your choices and the possibilities are endless.
