Hi B,
You should be fairly safe if you avoid rice, rotis, nan, bread, noodles, pasta and any dishes containing peas, carrots, beetroot and potatoes.
Palak paneer (spinach with cottage cheese), mushroom curry, salads, any kind of mutton or chicken curry, prawns, tandoori chicken, fish fry etc should be ok.
I notice from your stats that your weight is pretty decent. Since India has some absolutely fab cuisine not to mention the great mithai, why dont you take the opportunity to sample the fare and get back seriously to LCing when you return? It would be a great pity if you were to go back and miss all this great food!! Besides, just keeping off the rice, chappatis and other cereals should do the trick for you.
But you are the best judge, dont let me throw you off course.
All the best
Anu
