How Fast Does My Body Digest Protein?


The article concerns the question – How Fast Does My Body Digest Protein? The challenge set for every individual is to have a balanced diet in order to stay healthy, and although the nutritional requirements may vary from person to person depending on lifestyle and diet, the foods we all eat come from the food groups. These groups are classified into carbohydrates, proteins, and fats and are broken down by digestion into its components.

How Fast Does My Body Digest Protein?

How protein digestion works

Let me begin with a brief description of the digestion process. This is the method whereby food is moved through the body and broken down in the stomach. This is followed with the chemical breakdown of food primarily in the small intestine and the digestion process then continues with the absorption and distribution of these molecules abound body. The digestion time of the food itself is dependent on the individual and such factors as body weight, health, and physical activity.

In the world of dieting and health regimes people are concerned by which foods they eat, more specifically ‘good foods’ and what can be most efficiently and quickly absorbed by the body to provide the  best and most effective results for that all desired and aspired for perfect figure.

Essentially, I want to talk about how fast the body can digest protein. However, I firstly want to take a brief look at carbohydrates. These are found in three different groups: simple, complex, and fibrous. The more complex the carbohydrates the harder the body works at breaking it down to absorb into the bloodstream. Simple carbohydrates include sugar products and fruit sugar which are quickly absorbed into the blood stream. Complex carbohydrates include whole grain and starchy products and fibrous carbohydrates are carbohydrates from some fruit and vegetables.

So what about protein supplements?

My focus is now on proteins which we as humans ingest and these can be divided into two main categories: animal source protein – meat, milk, eggs, and vegetable source proteins. The different properties of a specific protein affect the rate of the digestion process in the body. It is in fact content of the amino acid mix in the proteins which is the essential building block in the creation of muscle from protein.

In recent research, it has been proven that casein protein is digested slower than whey protein and therefore protein supplements which consist of whey protein have become a common method of increasing protein intake in the body. These are more frequently being used in high protein diets as well as by bodybuilders who want to increase muscle mass in the body as swiftly as possible.

Whey protein is more rapidly digested and can be absorbed at a rate of 8g to 10g per hour as opposed to casein protein which is absorbed at a slower rate of 5g per hour. Therefore, whey is more desirable because it takes less time to digest than casein which can take twice as long. Through the manipulation of the different proteins we can try to create the perfect balance in the body and help create the beautiful body that we all dream about in today’s health conscious society.
