I can understand how one would interpret it that way - implying that milk, butter and bread are not staples in Indian food - but I don't think that's the case.

I can understand how one would interpret it that way - implying that milk, butter and bread are not staples in Indian food - but I don't think that's the case. The wording is confusing, but I think we get the most consistent meaning interpreted my way. Whether or not that interpretation actually represents reality, however, is a different matter.
