It is known that taking a large amount of fluid facilitates the onset of seizures. There are even special methods of provoking seizures with the help of “water strikes.” On this basis, some authors recommend a sharp restriction of fluid intake or increased excretion of it from the body. Since ancient times, for the treatment of epilepsy, food with a limited content of sodium chloride (salt-free diet) was recommended, fasting (fasting) was periodically arranged. Treatment with fasting, salt-free, and later protein-free diet did not give convincing results. Patients with epilepsy can eat, with some limitation, all that their family members eat. Mandatory is the categorical prohibition of alcoholic beverages, including beer, dry and low strength wines. Numerous observations show that alcohol is the main factor provoking seizures, even if they are absent for several years, and dramatically aggravates the course of epilepsy. Spicy and salty dishes, herring, sprats, salted and pickled vegetables (cucumbers, tomatoes, cabbage, mushrooms, squash), spices (vinegar, pepper, horseradish, mustard) are not allowed. Products containing an excess of nitrogen (beans, peas, beans), smoked and indigestible foods are not recommended. Do not abuse fluid. In one patient, attacks occurred after drinking 3-4 bottles of lemonade. But you should not go to the other extreme, constantly drastically limiting the amount of fluid. Sometimes the patient may be allowed to eat a piece of herring, but this should not be included in the daily diet. Overeating should be avoided, as it can contribute to the onset of seizures. We observed a patient in whom a series of seizures occurred after a hearty meal. The menu should be varied and include a sufficient amount of fiber, vegetables, fruits. These foods promote better intestinal motility and inhibit constipation. To combat the latter, boiled beets and its juice, prunes are useful on an empty stomach. Patients with epilepsy are usually prescribed a dairy-vegetable diet. However, one cannot exclude meat and other products containing proteins from the diet, especially since a number of antiepileptic drugs (hexamidine, etc.), even at therapeutic doses, can have a side effect on the liver, in which case a protein diet is indicated. The content of meat and fish in food should be average, they should be consumed mainly in the form of boiled dishes. Thus, patients with epilepsy should be advised to eat with a somewhat limited amount of liquid and sodium chloride. Food should be rich in vitamins.
