Regression fever is an acute infectious disease caused by insect-borne spirochetes, characterized by periodic high fever with generalized pain, hepatosplenomegaly and bleeding tendency, and jaundice in severe cases. Depending on the vector, it can be divided into two types: louse-borne regressive fever (epidemic regressive fever) and tick-borne regressive fever (endemic regressive fever). What are the dietary considerations for regressive fever? Patients are advised to eat foods that are cold in nature; foods high in vitamins; easily digestible liquid or soft foods; avoid eating warm foods; and foods within alcohol. Desirable foods Empty cabbage: cold in nature, easy to digest and absorb, and has the effect of cooling the blood, which is conducive to the fall of body temperature. Black rice porridge: rich in nutrients, high energy level, easy to digest and absorb, and high vitamin content, which has an auxiliary effect of lowering body temperature for this disease. Bamboo fungus: rich in nutrition, high amino acid level, easy to digest and absorb, has a role in promoting recovery from this disease. Avoid food Alcoholic beverages: Alcohol can stimulate cells to accelerate energy metabolism and induce a rise in body temperature, which is very unfavorable to the recovery of the disease. Absolutely contraindicated. Warm tonic meat: Dog meat, mutton and other warm tonic foods should be eaten sparingly to avoid further increase in body temperature, which will affect the recovery of the disease.
