Absorption allows nutrients to travel to our organs
The human body is a super sophisticated machine able to feed itself from the food we bring to it. Our diet begins with the ingestion of solid or liquid foods that will pass through the different areas of our digestive tract, esophagus, stomach and intestines. These foods are digested mechanically (fragmentation) and then chemically (this is the role of enzymes) to be transformed into nutrients. They become substances that enter the body through the walls of the intestine. Macronutrients (lipids, carbohydrates, proteins) and micronutrients (vitamins, minerals) are transported by the blood via the blood vessels of the intestinal wall. They will carry the nutrients to the liver that will distribute them to different organs and provide them with what they need.

Malabsorption of nutrients can cause deficiencies
Digestive malabsorption is a disruption of food absorption due to intolerance to a substance (gluten, milk protein), pancreatic insufficiency or other intestinal disease. In case of gluten allergy, for example, the abnormal immune response in the small intestine causes inflammation. The lining of the intestine is damaged and can no longer absorb nutrients. It follows gastrointestinal disorders, deficiencies. Biological tests make it possible to know the intestinal absorption capacity.
