The importation of milk powder by the united states is the result of the high-quality dairy products officially promoted by the united states in china since the introduction by the chinese government of a production company registration certification system in 2013. It is also the result of a joint study by food and nutrition experts, using advanced equipment, natural raw materials and a formulation of newer international nutrition standards. Ancan's milk producer camped infant and child formula. The united states imports milk powder produced by matek (the world's largest and zui's well-known dha producer) with a structure equal to that of a breast-milk plant single-celled dha of 0. 36 per cent, significantly improving the intellectual and visual development of children aged 0-12 months. The world health organization (who) recommended that the content of dha in infant and young child milk formulas should be 0. 33 per cent, and that most markets for infant and young child milk brands are below this standard. The eu confirmed that dha levels above 0. 3 per cent are effective in promoting visual development. Importing milk powder from the united states avoids the use of fish dha, which has a absorption rate of less than 40 per cent, including epa and marine pollution risks, is not in line with the united states fda proposal and is not conducive to healthy infant growth。
