Why Animal Sourced Protein Is Better Than Plant Sourced Protein

29 July 2022

Plant-sourced proteins are raving right now in the market. You can’t walk down the health supplement aisle in your local grocery store and not see a single plant-based protein on the shelf. Seeing them this frequently you may have asked yourself “Are plant-sourced protein powders really good? Are they good in comparison to animal-based protein powders?” You are not alone... Not to worry, we are going to explain to you the difference between plant-sourced and animal-sourced protein and help you understand why animal protein is superior to plant-sourced protein.

Animal-Based Protein

Animal proteins are complete proteins and contain nine essential amino acids. Sea foods such as wild-caught fish are known for their rich source of protein, and high amounts of vitamin D, vitamin B, and omega 3 fats. It also contains minerals such as selenium and potassium.

Another excellent source of animal protein is organic, grass-fed meat. There are many choices depending on where and how it was raised. Lean and red meats such as bison are low in salt and fat. Untrimmed lamb, pork, and beef contain high amounts of total and saturated fat. Poultry and meat are high in fat-soluble vitamins and proteins such as vitamin D, vitamin A, vitamin B, amino acids, zinc, and iron.

Plant-based protein

Plant-based proteins are very popular in the market, especially among vegetarians and vegans. However, the fact is that these proteins may cause more issues than good due to the harmful ingredients used in them. Plant-based proteins are generally sourced from ingredients such as soy, grains, legumes, and hemp.

As soy is rich in protein, it is commonly used in plant-based protein powders. It is made from processed soybeans and almost every soybean in the U.S is genetically modified. GMOs are linked to kidney diseases, rheumatoid arthritis, thyroid diseases, and even cause infertility.

Pea protein is also derived from legumes which is another popular choice for vegans and vegetarians. Due to the high fiber content, plant proteins are digested slowly compared to animal-based proteins and this can limit the number of amino acids bioavailability to make protein.


Gluten is the source of protein found in most grains such as rye, barley, and wheat. When you consume Gluten, it travels to your small intestine where it triggers the release of zonulin. Zonulin is a chemical that signals tight junctions of the intestine wall to open up, thereby creating an intestinal permeability known as leaky gut. Once your gut becomes leaky, large proteins such as gluten, toxins, microbes, and partially digested food particles escape through the intestinal wall and your immune system starts reacting to fight off invaders. This leads to chronic inflammation as your gut is leaking and the body continues to function in defensive mode.

Whey and Casein Proteins

Cow’s milk technically is an animal-based protein. It contains whey and casein. Whey is a protein that is often separated from the casein in milk and one of the biggest cons of whey protein is that it contains lactose. Lactose is the sugar found in milk that many people have a problem digesting. Casein and lactose are both found in whey protein and people with lactose intolerance must avoid consuming it.

The real issue with casein is that it comes from the molecular mimicry of gluten. If you are gluten intolerant then you are more likely to have casein intolerance as well.

When you compare animal-sourced protein to plant-sourced protein, animal-sourced protein is the clear winner. Proteins from nuts, seeds, and legumes do not contain all essential nine amino acids and they are highly inflammatory and difficult to digest. Inflammation can lead to gut imbalances such as SIBO, Candida overgrowth, and leaky gut and eventually leads to autoimmune diseases.

Protein is an essential part of our diet. And a healthy diet plays a significant role in managing the autoimmune condition. when you are dealing with autoimmune diseases it’s important to take a protein-rich diet coupled with clean food sources that keep your autoimmune symptoms at bay.
