濟南家政談到有一些家長(cháng)總想給孩子早一點(diǎn)添加輔食，似乎早一點(diǎn)添加輔食孩子就會(huì )越吃越壯，但是過(guò)早添加輔食對孩子害處多多，這是因為小嬰兒胃腸道發(fā)育還不成熟。
Jinan housekeeping always want to talk about some parents give their children a little early complementary feeding, it seems a little early complementary feeding the child will eat more strong, but too early complementary feeding a lot of harm to the child, it is because the baby gastrointestinal development is not mature.

濟南家政建議應在嬰兒滿(mǎn)6個(gè)月時(shí)再添加輔食，因為腸粘膜屏障包括它的物理性保護機制以及腸淋巴組織、分泌性免疫球蛋白細胞免疫的免疫性保護機制，要到嬰兒6個(gè)月時(shí)才能發(fā)育完善。因此，在出生后的頭幾個(gè)月中，嬰兒腸道的通透性較大，一直持續到嬰兒3～4個(gè)月時(shí)。而且消化酶系統也發(fā)育不成熟，造成進(jìn)入體內的蛋白質(zhì)未充分分解即吸收入血，引起胃腸道過(guò)敏反應。小嬰兒又缺乏分布于腸粘膜表面的保護性抗體——分泌性免疫球蛋白A，缺乏此類(lèi)抗體可使腸道細菌在粘膜表面造成炎癥，這樣便加速了腸粘膜對異種蛋白吸收，誘發(fā)胃腸道過(guò)敏反應。同時(shí)再伴以較大的腸道通透性，使得嬰兒容易發(fā)生過(guò)敏。一小口食品中的抗原量可能是母乳中同種抗原的1000倍。因此根據世界衛生組織的建議嬰兒6個(gè)月以后再添加輔食，尤其對于有過(guò)敏傾向的家族史的孩子。
Jinan domestic proposals should be complementary feeding in infants over six months, because mucosal barrier, including its physical protection mechanisms and intestinal lymphoid tissue, immune protection mechanisms of secretory immunoglobulin cellular immunity to the baby 6 months perfect time to develop. Thus, in the first few months after birth, the infant intestinal permeability larger lasted three to four months a baby when to. But also immature digestive enzyme system, resulting in a protein into the body that is absorbed into the bloodstream is not fully decomposed, cause gastrointestinal allergic reactions. Baby and lack of distribution in intestinal surface protective antibodies -secretory immunoglobulin A, the lack of such antibodies can cause inflammation of the intestinal bacteria in the mucosal surface, thus accelerating the intestinal absorption of foreign proteins, induced gastric intestinal allergies. At the same time again accompanied by large intestinal permeability, making the baby prone to allergies. A small mouth food may be 1000 times the amount of antigen in breast milk alloantigens. So then add complementary according to World Health Organization's recommended for infants 6 months later, especially for a family history of allergy-prone children.

濟南家政介紹小嬰兒唾液腺分泌相對的少，4個(gè)月才開(kāi)始逐漸增加，5～6個(gè)月分泌量增多，唾液具有消化和抑制細菌生長(cháng)的作用，同時(shí)唾液還有消化酶，主要是淀粉酶分泌增加，能對食物進(jìn)行初步的消化作用。
Jinan housekeeping introduce baby salivary secretion is relatively less, began to gradually increase four months, an increase of 5 to 6 months secretion, saliva has digestive and inhibit the growth of bacteria, and saliva as well as digestive enzymes, mainly amylase secretion increase, able to preliminary digestion of food.

濟南家政提醒根據孩子生理發(fā)育的特點(diǎn)是不能早添加輔食的，當然每個(gè)孩子發(fā)育是有差異的。如果你的孩子已經(jīng)完全具備添加輔食的條件就可以添加了，但是最早不能早于4個(gè)月，最晚不能晚于8個(gè)月。
Jinan housekeeping remind according to the child's physical development is characterized by early complementary feeding can not, of course, there is every child developmental differences. If your child has been fully equipped with complementary feeding conditions can be added, but not earlier than the first four months, the latest no later than eight months.
