Protein Digestion Steps which are a must for muscle building

The high protein diet trend has been a constant in the world of fitness, even if people hardly understand how their bodies function. Let’s make this clear at the very beginning: High protein consumption does not translate to heavy and strongly built muscles. Protein digestion steps are some of the most complicated processes of the digestive system as the amino acid chains are the most difficult to digest.

Uneven protein consumption leads to strange body shapes. While the upper body may grow wide and muscular, the legs remain slim. Apart from being visually discouraging, unevenly grown muscles are detrimental to our health and physical fitness.

We are whatever we consume. Much like we try to understand everything around our house, we should also have a clear understanding of what goes inside our stomachs. Our bodies are home to our precious minds. What we eat shall ultimately construct our mind and body into one wholesome setup.

The protein consumption rates have increased over the years as part of fitness modules. Gyms recommend high protein diets, protein shakes, and capsules. They do not entertain the fact whether the users’ bodies are ready for absorbing the intake. A fair amount of understanding is required and this is where Fleetbud comes into play.

We are here to provide you with all that is crucial to understanding the concept of physical fitness. Your physical fitness depends on each aspect of your body being taken care of, fulfilling all their needs. From taking the food into our mouth until the process of egestion, it is one long complex process that incorporates various enzymes, hormones, secretions from various organs at play during digestion.

Before going into the details of protein digestion steps, let’s understand what we mean by protein?

What is protein?

Proteins are long chains of amino acids that combine with longer chains. These amino acids break down to add to the structural chains of muscles, tissues, fibers, nerves and all vital organs in the body. Amino acid chains were the most primitive forms of life that evolved. Trillions of such amino acid chains come to form life as we know it today.

Thus, in order for our body to function properly, it is essential that the amino acids assimilate with the blood, and retain the muscle mass in the body. But here is a catch. If we consume too much protein, it does not necessarily add to the muscle mass. Protein absorption is not synonymous with protein consumption. In the next article, we shall discuss the details of protein consumption and absorption by the body after a meal.

Being one of the most complex molecules for the body, numerous enzymes and secretions break the long chains of amino acids. In other words, for the perfect unfolding of protein digestion, the entire body requires a balanced fitness module. Extra protein intake does not help at all. Rather they get lined on the arterial walls and veins, bringing blood pressure up and increasing obesity and chances of heart attacks.

What are the Protein Digestion Steps?

Protein digestion begins in the mouth. It is the very first food component that starts getting digested, and it takes the most amount of time to absorb into the bloodstream. The very first part of the entire process of protein digestion is known as mastication.


Mastication is the process of breaking down the food into numerous small particles in the mouth. Protein foods require a lot of chewing and mixing with the saliva so that the enzymes in the stomach get a larger surface area to act upon. Proper chewing and saliva convert the food into a semi-solid bundle, reaching the food into all the essential body parts dedicated to protein digestion.

Inside the stomach

Digestion of protein within the stomach begins with the enzyme pepsin. After the food is sufficiently chewed, the hydrochloric acid in the stomach activates protein digestion. The stomach linings secrete the acid while activating other enzymes like pepsin. Pepsin is a protein-digestive molecule that is present in abundance in the intestinal walls. As the food passes through the walls, a pancreatic juice neutralizes the acidic secretion that mixes with the protein-rich food components and breaks them down further. It is through this process that the protein components convert into peptides and from the stomach they pass into the small intestine.

Inside the small intestine

Protein digestion enzymes are central to the conversion of protein into a peptide. This conversion is crucial for increasing muscle mass. Therefore, it forms an inevitable part of our physiology, physical fitness, and protein digestion steps.

To neutralize the acidic sustenance particles originating from your stomach, your pancreas secretes a bicarbonate buffer into your small digestive tract. The inert condition of this bit of your gut energizes the movement of more protein-processing chemicals. It starts with both your pancreas and the cells covering your small digestive system.

These catalysts act on the peptide bonds, separating them into much littler peptides and afterward clipping off the amino acids one by one. Now, the absorptive cells of your small intestine convey the single amino acids to your circulatory system and after that on to the cells all through your body.

Controlling protein digestion

Your body manages protein absorption through hormones and nerve signals. Gastrin invigorates your stomach cells to deliver acid, while secretin advises your pancreas to discharge both bicarbonate and stomach related proteins.

Cholecystokinin is a third hormone associated with protein processing. It likewise guides your pancreas to discharge stomach related catalysts. Your sensory system aids protein assimilation by reacting to the proximity of sustenance in your stomach related tract. The incitement of nerves around the intestine helps move the digested food through the diverse organs of the body. We need to perform certain activities for regulating the steps of protein digestion properly which shall be discussed in another article.

The key to protein digestion is a balance

Fats, carbohydrates, and proteins go hand in hand. Carbohydrates maintain the sodium/potassium levels in the body, which go on to produce an efficient pathway among all nerve endings.

Protein and starches cooperate to keep your body solid and working. Breakdown of starch gives you vitality, while the protein assembles muscles, skin, and hair. Both are crucial in balancing out glucose and are best when eaten together. Basically, without carbs, your body would not have the capacity to work. What’s more, without protein, you couldn’t fabricate muscle or develop skin and hair. They are similarly basic!


It is not advisable to fall for shortcut fitness modules. Protein digestion steps are fundamentals to our physical fitness, much like carbohydrates is a prerequisite condition for going through the day. Consuming high protein foods in the hope that it would increase muscle mass in a short period of time is detrimental to health. What is required is a nice balanced diet, proper exercise, and deep sleep. These three elements cannot be discounted if a fit and healthy body is the aim.
