How did Indian diets change after arrival of Muslim kings?

I would like to know how did the diets of people changed due to the new kingdoms that came in and took over the Indian Subcontinent. Was it earlier more vegetarian due to religious reasons and shifted to non vegetarian due to the new culture and as claimed by the Right Wing Politicians in India who say that the Mughals forcefully imposed their cultures or was the diet pretty much the same.

I've read about the eating habits on websites such as here but there is no authenticity.
