The girl I am seeing has a not so good taste "down there" how to tell her?

Here's he thing, she is Indian and I've been reading up that it could be due to the spicy foods. Obviously, being Indian, she eats a lot of spicy food and I'm wondering if this could be the problem. If so, how the hell do I go about telling her? It's not like she's just going to change her diet as that is the food she and her family eat. Advice?
