Kalki,

When something is Scientifically proven then there must be a PEER REVIEWED JOURNAL published. Can we all have link to those verifying your claims?

Cow's milk is not 100% human milk. That is completely wrong. Cow's milk or any animal's milk for that matter have bacteria in them which may be harmful and even deadly for human consumption. This is the reason why pasteurization and boiling is recommended. Mother's ( i don't mean Cow) milk have anitbiotics which is good for the babies.

All meat products have certain risk associated with it not just Cow. Again if you have any study done about cow's hormone being especially harmful let us know. If cow's meat have harmful hormone then so will the milk as well. So your argument is invalid.

Humans are Omnivorous. They are capable to digesting most of the food types.

Lastly, Don't try to make any religion as if it is somehow scientific. You only would look like a Fool. I am sick of people trying to justify their beliefs by using pseudo scientific logics which has never been proven.
