A mechanism for regulation of oral and gut microflora by interaction of salivary metabolites with breast milk

唾液“缺乏鲜血的戏剧性、汗水的真挚和泪水的情感感染力”。但唾液对口腔有重要作用，那就是消化。如今，布里斯班的研究人员发现，婴儿流口水中含有天然化学物质，可以在细胞中形成“核苷酸”。他们正在测试这样一种理论，即核苷酸促进口腔和肠道中的友好细菌。当婴儿的唾液与母乳混合时，它还会产生天然的抗生素，称为“氧化自由基”，可以阻止有害细菌。这可能是确保“母乳对婴儿最好”的机制的一部分。

Saliva "lacks the drama of blood, the sincerity of sweat & the emotional appeal of tears". But spit has important roles for the mouth & digestion. Now researchers in Brisbane have found baby dribble has natural chemicals that form ‘nucleotides’ in cells. They are testing the theory that the nucleotides encourage friendly bacteria in the mouth & gut. When baby saliva mixes with breast milk it also makes natural antibiotics called 'oxidative radicals' that stop bad bacteria. This may be part of the mechanism ensuring "Breast is best" for babies.
