The intestinal absorption in infants

Maturation of the baby's intestine
Although since the beginning of fetal development is occurring increased intestinal surface necessary to successfully complete the absorption of nutrients as well as certain mechanical actions (suck-swallow), the full functional anatomical development of the gastrointestinal tract should be performed after birth. The approximate length of the intestine at birth is 275 cm, where there are already villi and microvilli necessary for the transition to a new food outside the womb. It will complete the coordination of suck-swallow neuronal and breathing, gastroesophageal sphincter contraction, gastric emptying and peristalsis.

While the system ends of maturing is normal to find regurgitation in infants (there may be danger of aspiration of gastric contents in trachea and lungs, especially in premature babies, which has been associated with esophageal adenocarcinoma).

The absorption of certain nutrients can not be done yet: some proteins by low secretion of gastric acid pH is still low, some lipids where there is still debate about the usability of desaturase and elongase for the formation of fatty acid chain 20-carbon absorption in the duodenum of complex carbohydrates in the first months, mainly by the absence of further maturation of pancreatic enzymes. Throughout this process are involved in specific intestinal cells: enterocytes, mucous cells of the calyx, Paneth, endocrine cells, M cells to the immune defense, unions interepiteliales (required vitamin C, L-glutamine, omega-3 series, essential amino acids) and the development of microflora. All this will be the prevention of infant to infection, inflammation and possible complications in adult life.

Zinc and the baby's intestine

There are also special attention to several minerals, most notably zinc, one of the most important and we can find nutritional deficiencies as due to the depletion of arable soils are depleted of this mineral, and plants at these places and the animal that eats them will also have some Zinc. In addition, low dietary protein intake hinder its uptake (especially duodenum) is favored because the amino acids and peptides. This mineral is very important for gene transcription (to avoid errors, zinc fingers) to ensure a properly functioning immune system and prevent immunodeficiencies, processing in the thymus of T cells in their selection among them should be and which must be removed not to attack self antigens (thus avoiding autoimmunity), a good growth of the infant and multiple metabolic processes as part of many enzyme systems and coenzymes.

Lack of zinc is detrimental to the functional capacity of immune system cells. Also, do its association with vitamin D, the source steroid action and more in keeping with hormonal processes and intervening in multiple activations, also essential to the proper selective regulation of the immune system. Vitamin D to its formation is dependent on cholesterol, vitamin B5, Zinc, UVA. Here comes back the importance of an accurate dose of this mineral. Vitamin D is also necessary for organogenesis, and good absorption of calcium and phosphorus needed for growth. We also saw a partnership as a regulatory cell-braking systems, because what you see its application in certain cancers. This is essential at a time of maximum growth in the infant.
