Patients with trigeminal neuralgia should refuse any spicy and stimulating food. Spicy and stimulating foods can have an irritating effect on the nerves. In particular, stimulating the trigeminal nerve can strengthen the nerve impulses, which can trigger trigeminal neuralgia. Common spicy foods include hot sauce, onion, garlic, ginger, Peking onion, mustard, etc. Patients should avoid, both during treatment and in the interval, the intake of such foods. Patients should also not eat fried or deep-fried foods, because greasy foods can easily nourish dampness and produce phlegm, which can cause the head and face to become blocked, thus triggering trigeminal neuralgia. Therefore, patients should avoid fatty pork, pork, butter, fried chicken and duck, which is a point that should be noted in the trigeminal neuralgia diet taboos. The main reason why trigeminal neuralgia should stay away from hard fruit foods is that these foods require hard chewing, which is a very common triggering factor. Therefore, patients suffering from this disease should try not to eat, hard fruit foods. The common hard fruit foods on the market are walnuts, pine nuts, hazelnuts, chestnuts, peanuts, fava beans and so on. If the patient consumes raw and cold food, it will induce the strengthening of trigeminal nerve impulses, thus triggering the trigeminal neuralgia. Therefore, in the process of treating trigeminal neuralgia, patients should try to avoid the intake of raw and cold foods, such as ice cream, iced watermelon, ice lollies, iced drinks, etc.
