Experts warn that patients with trigeminal neuralgia need a high-carbohydrate diet to supply energy and protect neurological function, requiring 350 to 400g daily. Fat is an important component of the cells that make up human tissue. In particular, phospholipids and sterols, etc. Both brain and peripheral nerve tissue contain sphingomyelin, which is important for animal growth and development and also increases the immune capacity of the brain. Fat can be more vegetable fat to avoid elevated cholesterol. Vitamin B1 and vitamin C are important to protect against cranial nerve damage. Vitamin B1 is the main wan of decarboxylated coenzyme and plays an important role in the metabolism of carbohydrates. Lack of vitamin B1 can cause neuritis because nerves are the tissue that burns and consumes sugar. If vitamin B1 is lacking, it can cause lactic acid to accumulate and invade the brain, poisoning the central nervous system and making the brain tissue less able to consume oxygen to the point of causing temporary spasms. And trigeminal neuralgia, sciatica, etc. are all manifestations of neuritis. The daily supply of vitamin B1 for adults is 1.2 to 1.8 mg, and the therapeutic amount is 100 mg. The supply of vitamin C is 75 mg, and the therapeutic amount is 200 to 300 mg. When preparing meals, prohibit stimulating wai food, such as onion, raw onion, garlic, fresh persimmon pepper, leek, garlic yellow, etc. Forbid the use of stimulating condiments, such as dried chili, five spice powder, mustard, curry powder, etc. Prohibit the consumption of various kinds of alcohol. The temperature of the meal should be appropriate, not too cold or too hot, in order to avoid chemical and physical stimulation, causing intense melting. If the sensory fibers are stimulated, it is easy to cause facial nerve hypesthesia and trigeminal nerve pain. And can stimulate the animal branch nerve, intensifying masticatory muscle atrophy. In addition, in the diet, the diet supply mode can be given fluid, 5-6 meals per day, should be prepared with high protein, high sugar liquid food, such as milk punch lotus root powder, milk punch egg flower, chicken soup dumping egg flower, meat loaf over wok porridge and other thick fluid, so that patients have a sense of satiety. Or use a high speed pounder to pound noodles, rice, porridge, dumplings, stir-fried vegetables, braised meat, etc., all into celiac food for patients to eat.
