Infant food digestion characteristics of dietary intake in infants

Infant food digestion characteristics of the infant's diet is very important, because they are long and physical development stage, a good diet can increase immunity in children, the infant diet digest what are the features together to see infants and small series features of early childhood diet digestion introduce it!Infant nutrition diet digestion characteristics of children with the most important and most difficult stage of infancy, rapid infant growth and development, metabolism, nutrient requirements is relatively higher than that of adults, but weak digestion than adults, so the supply of essential food supplies combined with its digestive function characteristics, reasonable feeding, in order to avoid malnutrition and digestive disorders。 (A) Oral: baby cheek fat pad development is good, help sucking activities。
Incomplete differentiation of neonatal salivary gland, small amount of saliva secretion, wherein the amylase content is insufficient, it is premature to feed food starch。
3?At 6 months before fully developed salivary glands, saliva increased amount of amylase content also increased。
At this ability, all children no swallow saliva, physiological salivation often occur。
(Ii) Gastrointestinal: gastric neonatal and adult substantially the same components, containing more chymosin。 Although low acid content, rennet only work at low stomach acid, the digestion of milk is very adapt。
Gastric emptying time varies due to the type of food, water?Breastfeeding 2?3 hours; 3 milk?4 hours, due to the larger milk clot in the stomach to stay longer。 Fever, infection, malnutrition and other factors will affect the stomach time to digest, semi-solid foods can promote gastrointestinal motility。 Baby intestine total length of about 6 times the length, and the adult only times, which is very beneficial for digestion and absorption。 But intestinal incomplete decomposition products, in particular, the permeability of the micro-organisms are higher than in adults and older children, it is easier to cause systemic infections and allergic diseases。 Infant food digestion Characteristics (III) in the neonatal period has been able to secrete more of trypsin, pancreatic amylase and lipase。
two.Pediatric nutrition requirements (a) calorie needs: general metabolic activity of cells requires heat, the heat is supplied by an external source of nutrients。 1G, protein or 1G, sugar provides energy 4cal, 1G fat provides energy 9cal。 Pediatric heat required include the following:。
