So, if you feel the inclination to cut garlic and onions out of your diet, try it out and see what happens. If you do not, then that is fine as well.
Nisargadatta Maharaj said (and I am paraphrasing) with regards to such practices that anything one does in seeking to realize the truth will be helpful, and anything one does in forgetfulness of enlightenment will be harmful. The question you have to ask yourself is whether you have any inclination to do so. Personally, I don't see how garlic and onions in moderation could do any harm, but that is up to each individual to decide.
