Undifferentiated somatoform disorder is a psychiatric disorder in which the patient complains of one or more somatic symptoms for which he or she is suffering, but medical examination fails to reveal evidence of somatic disease or any organic pathology. Therefore, the diet can eat more of the following foods. 1, vegetable oils, vegetables and fruits: the body’s endogenous antioxidant system is very weak, mainly dependent on exogenous antioxidant system. Vitamin E is able to prevent cell membrane lipid peroxidation; vitamin C prevents intracellular protoplasm and cytosol peroxidation. In this way, vitamin E and vitamin C provide a complete exogenous antioxidant system. Early schizophrenia is likely to have oxidative stress and cellular damage, and eating more vegetable oils (rich in vitamin E), fresh fruits and vegetables (rich in vitamin C) can prevent this neurooxidative damage and improve prognosis. 2, safflower oil and soybean oil: to serve antipsychotic schizophrenia patients with 12 capsules of Efamol per day (each containing 360 mg of linoleic acid and its metabolite γ-linolenic acid 45 mg) or add a placebo, 4 months after the cross-use, the results found that the capsule served than the placebo significantly improved the psychopathology rating scale score 20% -30%, the results. Safflower oil, sunflower oil, soybean oil and corn oil rich in linoleic acid is high, can be supplemented. 3, seafood: an open-label trial of 20 cases of chronic schizophrenia patients with omega-3 fatty acids high in 10 grams of oil (each containing 171 mg of eicosapentaenoic acid and docosahexaenoic acid 114 mg), the results found that the positive and negative symptoms have improved, but only the negative symptoms improved to statistical significance. The results were not replicated in another study. Seafood, including algae, mollusks and fish, contain omega-3 fatty acids, which participate in the synthesis of phospholipid membranes and are beneficial to schizophrenia.
