How does protein breakdown work in your body?

Protein is a nutrient found in all food. That is why it is also very important for building and maintaining our muscles, tissues and organs. When we eat protein, it is broken down into smaller particles, which we call amino acids. Amino acids are then used to make new proteins or to carry out other functions in our body. But how does the process of breaking down protein work in our body after you've just eaten a plate of protein-rich food? We'll tell you all about it in this blog.

THE PROCESS OF PROTEIN DIGESTION

The digestion of protein starts in our gastrointestinal tract. When we eat protein, it is broken down in the stomach by hydrochloric acid and enzymes. These enzymes help break down the long protein chains into shorter amino acid chains. These shorter chains then move on to the small intestine, where other enzymes break the protein down further into individual amino acids.

Once they have been broken down, the amino acids are absorbed into the bloodstream and transported to different parts of the body. They go where they are needed most. Some amino acids are used to make new proteins, while others are used as fuel, for example for more energy. This depends on what the body needs most at that moment.

The process of protein breakdown and build-up is dynamic and constantly changing in our body. It depends on how much protein we take in and on what our body needs at that moment. When you exercise intensively, you need more protein to build and repair muscles. In that case, the body will break down more protein to meet this need.

THESE FACTORS INFLUENCE HOW PROTEIN IS PROCESSED

Several factors influence how protein is digested and absorbed in our body. One of them is the quality of the protein we eat. Some proteins are easier to digest than others. This has to do with the composition of the amino acids. Proteins of animal origin, such as meat, fish and dairy products, generally contain all the important amino acids our body needs. Plant-based protein, such as beans and grains, often doesn't contain all the essential amino acids, however, and therefore has to be combined to provide a complete protein profile.

FOOD PREPARATION

Another factor that can affect the digestion and absorption of protein is the way we prepare our food. Some methods, such as cooking and pan-frying, can improve how digestible protein is. Other methods, such as deep-frying and grilling, can actually reduce it.

YOUR AGE

Our age and state of health can also affect how we process protein. As we get older, our digestion can slow down and we may break down and absorb protein less efficiently. People with certain health problems can also have difficulty digesting and absorbing protein.

HOW TO OPTIMISE YOUR PROTEIN ABSORPTION

If you want to optimise your protein intake, there are several steps you can take to improve digestion and absorption. First, it's important to eat protein-rich foods that are easy to digest and contain good protein. That means animal products such as lean meat, fish, poultry and eggs. But also plant-based protein sources such as legumes, nuts and seeds.

Second, it's important to prepare your food the right way. Cooking and pan-frying are good ways to prepare protein, for example, while deep-frying and grilling can reduce digestibility. It's also important to drink enough fluids to make digestion easier and improve the absorption of nutrients.

Do you find it hard to keep track of all your protein, weigh it out and cook it too? Then the meals from SportMeals can help. Our chicken meals or fish meals are packed with the right protein. They also save you a lot of time, because you don't have to stand in the kitchen for long.
