Intestinal absorption is the process by which nutrients from food are taken up by the cells of the small intestine and transported into the bloodstream for distribution throughout the body. This process involves the breakdown of food molecules into smaller components, the movement of these components across the lining of the small intestine, and the uptake of these molecules by specialized transport proteins. Intestinal absorption is a crucial step in the digestion and utilization of nutrients, and disturbances in this process can lead to malabsorption disorders and nutrient deficiencies. Researchers studying intestinal absorption seek to understand the mechanisms involved in this process, identify factors that can affect absorption rates, and develop strategies to optimize the absorption of nutrients for improved health and well-being.
