People suffering from asthma need to ensure that their diet does not create complications for their conditions. Therefore, it is important to make healthier diet choices that help them manage asthma and its symptoms. While no specific foods can trigger an asthma attack, there are certain food allergies that could. Moreover, unhealthy foods can also cause obesity, creating complications for asthma patients.
To help you, here are some foods that one should avoid if they have asthma.

• Dried foods
  Processed and dried foods contain large amounts of sulfites such as potassium bisulfite and sodium sulfite in them. These are considered harmful to people suffering from asthma. Sulfites are used as preservatives in pickled food, dried food, wine, etc, and are added to foods to increase their shelf life.
• Gassy Foods
  A patient suffering from asthma should avoid consuming vegetables and other types of food that can cause excessive bloating and gas. This could put a lot of pressure on the diaphragm, which can cause difficulty in breathing. So foods like beans, onions, garlic, carbonated drinks, and cruciferous vegetables like cabbage, broccoli, etc. should be avoided.
• Eggs
  Egg allergies are highly possible in children and sometimes get taken lightly. A serious asthma reaction could be caused due to consumption of eggs if the person is allergic to them; hence, asthma patients should avoid eating eggs altogether.
• Peanuts
  It is observed that children who are allergic to peanuts are more likely to develop asthma earlier in life. Anything that contains even the slightest amounts of peanuts could prove fatal to an asthma patient that is allergic to peanuts.
• Salt
  In our body, electrolytes that are absorbed from salts are responsible for the amount of water that is retained in the body. Excessive consumption of salt could lead to increased water retention, which causes inflammation in the body and blocks airways. This can be very fatal to an asthma patient.
• Wine or beer
  As mentioned earlier, sulfites are added in wine and beer as well. There are also a certain number of histamines present in wines that result in symptoms such as watery eyes and could also cause sneezing and breathless wheezing. These are harmful symptoms for patients with asthma.
• Packaged or prepared potatoes
  Pre-made potato mash mixes contain several ingredients in them such as whey powder, which is not necessarily added when mashed potatoes are made at home. Moreover, there are also several sulfites and other preservatives in them that are not good for patients with asthma.
• Shellfish
  Another set of allergic food that often gets neglected is seafood. Shrimp and shellfish are usually treated with a bunch of preservatives and could trigger a serious attack of asthma in patients who are allergic to fish and seafood.
