Why plant protein is now preferred more than animal protein?

Did you know that human body is made up of 20% protein?

You can get protein from many food resources. Every part in the human body from muscles to organs consists of protein as protein helps to build, maintain and repair the body’s structure. Since the human body does not store protein in any ways you need to add protein to your everyday diet in one way or the other. Protein is available to you through different food resources that include plants and animals.

Human body needs a balance of 22 amino acids; nine of these acids cannot be produced by the body.  A complete protein source provides you with these nine acids as proteins are made up of long chains of amino acids.

While some believe protein is what matters whether it is from plants or animals, many claim that plant protein is a much better source. Plant protein is now preferred more than animal proteins as it provides you with many health benefits and improves your lifestyle increasing the chance of living a disease free and longer life.

So let us take a look on the different characteristics of both the proteins and choose which one is better.

Benefits of animal protein

Animal products contains a good balance of amino acids while plant proteins are mostly low in methionine, tryptophan, lycine and isoleucine.

A complete protein source is one that contains the nine essential acids, Animal products are a complete source of protein. Amino acids are the basic unit of proteins, while most of the plants do not contain all the essential acids and are thus called incomplete sources of protein animal proteins are complete sources of protein and contains all nine essential acids.

A few animal products that are complete sources of protein are:

  1. Fish
  2. Eggs
  3. Red meats
  4. Dairy products such as milk, cheese, etc.
  5. Poultry sources such as chickens, turkeys, and quails.
  6. Less common sources of meat like boars, hares, and horses.

Animal products contain other beneficial nutrients which plant proteins might be lacking. Considering the fact that there still is a plenty of nutrients found in plant proteins that are no available in animal products. But since proteins are not found in isolation animal products are richer in other nutrients such as:

  1. Vitamin D – Some plants may contain vitamin D but that found in animal products such as eggs, dairy and oily fish is considered better.
  2. Vitamin B12 – This vitamin is mainly found in fish, meat, poultry and dairy products as a result of which vegetarians mostly suffer deficiency of vitamin B12.
  3. DHA- Docosahexaenoic acid that is hard to find in plant based foods is really good for brain health and contains essential omega-3 fat.
  4. Heme-iron- Absorbed better by the body, heme-iron typically found in meats especially red meat.
  5. Zinc- Zinc found in animal protein sources, such as pork, beef and lamb, gets much easily absorbed by the human body.

Having discussed the benefits of animal proteins, let us move on to the benefits we get from plant proteins that seem to overshadow those provided by animal based product.

Phytonutrients or plant specific nutrients and some antioxidants are found only in plant based food.

Fiber is an essential factor for human body.  Animal based factor do not contain fibers that are good to keep the digestive system in check. Plant proteins are rich in fiber.
