Why do you need a cochrane meta-analysis?
You do realize pubmeds are simply what is put into a meta-analysis? I can provide you a meta-analysis, but they aren't as specific in nature, which is why I didn't here.
They're more general rather than specific.

If I'm wrong and the sources I've cited aren't true, then provide a source for evidence to the contrary.
Give me a cochranet meta-analysis that says otherwise, because I can't find anything relevant in a quick search on their site.

I ask for a Cochrane meta analysis because I trust them and the standards they grade by.

Oh, well I can't find a single thing relating to general nutrition, only specific things like supplementation of (X) nutrient in infants in their search function.
