There is no best dietary treatment for allergic cough; unlike medicines, dietary treatments do not achieve the effect of curing the disease. Food can relieve discomfort by replenishing the body with water and various nutrients. When allergic cough occurs, you can eat more vegetables and fruits rich in vitamin C, such as tomatoes, cabbage, apples, pears, oranges, etc., which can replenish the body with water and various vitamins, and improve the body’s resistance. Eating them can moisturize the throat and relieve dryness and discomfort in the throat. People with allergic cough avoid foods that are easy to cause allergies, such as milk, fish, shrimp, etc., and spicy, irritating foods such as onions, ginger, chili and other foods. Although food therapy has some relief, but not as a cure, it is recommended to consult a doctor in time.
