Domestic milk powder is better than imported milk powder, goat milk powder is better than cow milk powder, and organic milk powder is better than goat milk powder. At present, domestic children drink two kinds of foreign milk powder, one is foreign brand milk powder produced or sold in China, and the other is milk powder that parents buy directly from abroad and produce and sell locally. The formula of milk powder sold abroad is determined according to the specific situation of the baby in the selling country, which may not be suitable for the baby in China. Recently, more than ten kinds of ultra-low iodine incidents of Japanese formula milk powder, including well-known brands such as Meiji and Morinaga, were recalled in an all-round way, but the milk powder from foreign purchasing channels in China was not recalled, which explained everything. The content of iodine and zinc in Japanese milk powder is extremely low. At present, the common Japanese milk powder on the market are Meiji, Morinaga and other brands, and the milk source is from Japan or Australia. Japanese milk powder is loved by many Chinese mothers because it tastes light and is not easy to get angry. It should be noted that Japan is close to the sea, and the food is mostly seafood, which is rich in zinc, so the original Japanese milk powder contains little or no zinc. Zinc intake is very important for infants in China. Once babies who drink Japanese milk powder for a long time are found to be anorexic and partial eclipse, mothers should be alert to whether they are short of zinc. After that, check to make sure that you are considering changing milk powder or adding some zinc supplements to your baby. Experts suggest that Japanese milk powder has strict requirements on water temperature. When stirring, it is best to use water at 70 degrees Celsius to ensure full dissolution and not destroy nutrition. European milk powder, calcium and iron are scarce. European milk powder is represented by brands such as Niulan and Samui, and the milk source comes from New Zealand, Ireland and Australia. European original milk powder is not as common as American and Japanese milk powder in the market, and mothers usually buy it directly from Europe through purchasing and other channels. Xu said that the biggest problem of European milk powder at present is that the content of trace elements can not meet the national standards, especially calcium, iron and zinc. Because the breastfeeding rate in Europe is above 90%, infant formula is only used as a supplement when breast milk is not enough. The diet structure of Europeans is different from that of China. Mothers get enough calcium, iron and zinc through diet, which can be passed on to their children through breast milk. Therefore, the requirements for the addition of trace elements are not high. China stipulates that every100g of milk powder should contain 2.5-7.0 mg of zinc, 300-600 mg of calcium and more than 6 mg of iron. However, when testing European milk powder, it was found that it was far from this standard. The original milk powder of a European brand 100g contains only 0.8 mg of iron, which is 6 mg lower than the national regulations. American milk powder is easy to get fat. American brands account for 70% of the domestic high-end infant milk powder market. Abbott, Wyeth, Nestle and other big brands have won the favor of many Chinese mothers. The milk source of American milk powder mainly comes from Europe and New Zealand. However, the nutrition consultant of a well-known American milk powder company revealed that the protein, fat and sugar contents of the original American milk powder are all added according to the maximum limit of the standard, so many children are prone to gain weight after drinking American milk powder. In order to prevent your baby from being overweight, you should take the minimum recommended amount of milk when feeding American milk powder. For example, it is recommended to pack milk powder 80- 100 ml each time, and 80 ml can be fed. Experts suggest that there are many bubbles when making American milk powder, so don't shake it hard when making it. It is best to let it stand for 5 minutes after it is done, so as to avoid spitting caused by drinking too many bubbles.
