Trigeminal neuralgia is a common neurological disease, and many patients tend to confuse the disease with toothache, so that the disease is delayed. If trigeminal neuralgia patients do not eat properly, then it will easily lead to the deterioration of the disease, how to eat the right food, what are the dietary contraindications of trigeminal neuralgia? Some trigeminal neuralgia patients’ pain is caused by neuritis caused by a lack of vitamin B. Therefore, a long-term diet of certain foods, such as refined white rice, will cause vitamin B deficiency in the body. Therefore, trigeminal neuralgia patients should eat more vitamin B-rich coarse food, which can make their nerves healthier. 2, abstain from strong tea, coffee Caffeine in strong tea and coffee can make the nerve excitability increased, easily trigger small artery spasm, thus aggravating the condition of trigeminal neuralgia patients. 3, taboo alcohol and tobacco intake too much alcohol, easy to cause vitamin B deficiency, inducing neuritis, which leads to trigeminal neuralgia. The alcohol content of white wine is high, and trigeminal neuralgia patients should drink less or not drink. The nicotine in cigarettes also has the effect of damaging nerves, and trigeminal neuralgia patients should actively quit smoking. 4, avoid excessive intake of sugar A sufficient amount of vitamin B is a guarantee of nerve health, while sugar, especially white sugar, not only has zero vitamin content, but also requires the participation of vitamin B in the process of sugar metabolism, making the original deficiency of vitamin B even more lacking. Therefore, patients with trigeminal neuralgia should not eat sugar in excess to avoid causing vitamin B deficiency induced pain.
