While sugar, soy, dairy foods and wheat products are typical culprits, any food that precipitates allergic reactions can trigger seizures, warns Dr. Lawrence Wilson. Food additives, such as monosodium glutamate, or MSG, and aspartame, can also cause convulsions. Food and food additive allergies can also trigger seizures in children who have abdominal pains, migraine headaches or hyperactive behavior, reports The New York Times. Other common seizure triggers include alcohol and drinks containing caffeine, explains the University of Pittsburgh Medical Center.
Sufferers may be able to pinpoint problem foods and substances by keeping a journal of seizure occurrences, suggests University of Pittsburgh Medical Center. While food can trigger seizures, it can also help keep the condition at bay; some individuals have been able to mitigate the condition by subsisting on a low-carbohydrate, high-fat, no-sugar diet known as the ketogenic diet that was developed in the 1920s, notes The New York Times.
As of December 2015, researchers are still studying the efficacy of a low-carbohydrate, high-protein diet, dubbed the Atkins diet, on easing seizures, according to The New York Times. Sufferers should not try out these or other diets without first consulting a doctor as they can adversely affect the operations of certain anti-epileptic drugs. In general, sufferers should subsist on a healthy diet that incorporates substantial quantities of fruits, fresh vegetables and whole grains.
