Unverified85% confidenceDecision RuleTime unknown
查看营养成分表时应区分'DHA'与'总ω-3脂肪酸'，部分产品用ALA（α-亚麻酸）或EPA充数，ALA需在体内转化为DHA且转化率不足10%，只标注ALA的产品实际DHA贡献极低

UnverifiedDHA添加量需≥0.2%总脂肪酸才有临床意义(约3.7mg/100kJ),很多国产奶粉标注含DHA但实际添加量低于此值,选购时看营养成分表每100g的mg数而非仅看是否含有80% similarUnverified选购时核查营养成分表中每份DHA的实际毫克数，部分产品标注'添加DHA'但每份含量不足20mg，参考意义有限80% similarUnverifiedDHA与ARA配比建议控制在1:1至1:2之间（ARA不低于DHA），单独高DHA而缺ARA可能影响脂肪酸代谢平衡，配方中ARA过低（DHA:ARA>1:0.5）不推荐78% similarUnverified该产品DHA含量偏低，若单纯以补充DHA为目的，需要额外搭配其他DHA补充剂才能达到推荐摄入量77% similarUnverifiedDHA含量需关注实际添加量而非仅看是否标注，建议每100g奶粉DHA≥50mg（占总脂肪酸0.2%-0.5%）才有实际补充意义，低于此量属于'概念添加'77% similar
