This isn't a religious/Jewish question or about living conditions over two millennia ago. I hear it's bad to drink milk while eating meat but hear no reliable scientific evidence to support it.

    Try as I might, I cannot find one scientific review of this. There has to be something. All I can find is people echoing what ive commented above, without any citation whatsoever. Some rabbi decided "dont cook a calf in its mothers milk", and a few thousand years later were still scratching our heads wondering why!

    Isn't milk used to cook some types of meat?

    The motivations for not eating meat/milk/fish together are all purely religious. I have never seen a single source claim that there is a scientific reason for this. If you can't demonstrate a notable claim that there's anything other than religious reason for this, then this question should be closed.

    @Jamiec: McDonalds uses real milk in their shakes? Now that makes me skeptical.

Calcium may inhibit iron absorption, but that doesn't necessarily mean it's "unhealthy", just that if you're eating red meat to contribute to your body's iron reserves, and drinking milk to achieve the same thing with calcium, it may be best not to have them in the same meal.

  • in which case, the better alternative is some orange juice (or anything with vitamin C), which increases iron absorption (ncbi.nlm.nih.gov/pubmed/2507689) Commented Dec 12, 2012 at 0:58
  • Orange juice is very high in sugar, so probably not very healthy to drink it often unless in very small servings.
