No garlic and no onions are standard prescriptions for hindu priestly folk. Orthodox folks follow it religiously. Many these days follow it only in festivals and other holy days. Also, like sibling comment says, jainism prescribes avoiding everything growing underground and you can ask for jain food if a place provides it. Some airlines make special affordances and have a jain meal option you can try.
