There is a lack of systematic research and clear conclusions on the diet for patients with epilepsy, and the following aspects can be used as reference and guidance. (1) Ketone body diet The ketone body diet is a high-fat diet that produces ketone bodies in the body after consumption by patients with epilepsy and is effective or can reduce seizures in some cases. However, high-fat diets are often rejected because they are difficult to tolerate. The diets that are considered effective are still being studied. (2) Supplementation of vitamins and certain elements It has been observed that patients with epilepsy are prone to convulsive seizures when their food is deficient in vitamin B6 and certain elements such as calcium and magnesium. Therefore, some doctors routinely apply vitamin B6 as an adjunctive therapy. (3) Avoid drinking alcohol Wine and alcoholic beverages have the potential to induce seizures in patients with epilepsy, and they should be instructed not to drink alcohol or to abstain from drinking. Although not every case of seizure is clinically related to alcohol consumption, doctors or family members should still advise them not to drink alcohol. If alcohol consumption is found to be significantly associated with seizures, abstinence should be mandatory to ensure safety. Tea can be substituted for alcohol at family and friend gatherings and festive holidays. (4) Establish a scientific diet Patients with epilepsy should ensure adequate nutrition and avoid eating too much or too hungry. However, it should be noted that if the patient is overweight, plus some anti-epileptic drugs have adverse reactions that increase weight, such as sodium valproate, carbamazepine, etc., then when taking measures to control weight or lose weight, further consultation with the doctor should be made, and do not proceed blindly. The weight gain due to drugs is mostly self-limiting, that is, to a certain extent, it will not increase again. Taking diet or restriction measures, if improper, will cause a drop in blood sugar, electrolyte disorders, is not conducive to disease control. In particular, a drop in blood sugar to a certain level can cause seizures, and certain electrolyte disorders can cause the same problem. The so-called spontaneous hypoglycemia is often seen in teenagers, especially in women, and should be given special attention.
