It doesn't present Indians as privatives who eat Monkey Brains.... the villains in the movie eat monkey brains, and are Indian, but the villagers who have had their sacred artifacts stolen by those villains aren't eating anything like that. It isn't presented as "typical" or "usual" or anything like that. Not to mention said people eating those things aren't portrayed as primitive at all - they're in a grand palace, and several of the guests there are clearly meant to be educated and have posh accents and such.
It's like saying the movie implies Indians can rip your heart out of your chest if they chant "Kali ma shakta di" or anything like that.
