A nourishing diet, including a variety of foods, will supply energy, help resist infections, deliver more oxygen to body cells, and reduce fatigue. Drinking plenty of fluids helps to keep mucus thin and keep airways open. Some people search for a diet treatment for asthma as an alternative to taking medicines. No such diet exists and sadly, much time, money and suffering are wasted in the search. If food allergies trigger asthma, avoid those foods.
Some individuals are sensitive to sulfites, which are used as preservatives in many foods.
