Yes, maybe it is useful to have separate tags. But similar names should 
be avoided, as they will get confused.
I suggest naming the tag "dairy_free" instead of "lacto_free".
That is much clearer as to what it is. In UK English, most people know 
what a "dairy product" is, not many would know what "lacto" means.

"Lactofree" is a UK brand for lactose-free milk and cheese etc. So it 
would be classed as "lactose_free=yes", but "lacto_free=no". Which is 
just going to cause confusion, as above.
