作用不大。Q:听说酸奶能补充益生菌,我到超市给宝宝买酸奶,想找最近两天生产的,却发现都是已经接近一周的。听说生产日期越近的酸奶越好,日期久的益生菌都“死”了。这是真的吗?另外,酸奶买回家后咋保存最好?给宝宝吃之前先常温下放置一段时间会不会影响益生菌的存活? not so useful. Q: I heard that yogurt can be added probiotics, I went to the supermarket to buy baby yogurt, looking for the last two days of production, but are found to have been close to a week. I heard that the closer the production date the better the yogurt, the probiotics have a long history of “dead ”. Is this true? In addition, the yogurt to buy home after the ye kept the best? To the baby before eating at room temperature for a period of time will not affect the survival of probiotics?
