Asthma is a respiratory condition where the airways narrow, swell, and produce extra mucus. These factors make it difficult for the person to breathe and trigger wheezing and coughing. Apart from treatment and home remedies, people with asthma tend to eat foods that can boost their recovery. But not all foods are suitable, and some may even worsen the condition. Here are seven such foods that may trigger severe respiratory symptoms.

Eggs
Eggs contain healthy nutrients, including proteins, vitamins, and minerals. However, asthma patients prone to egg allergies should avoid them. Egg allergies generally lead to reactions on the skin, such as hives. Eating eggs can also cause inflammation in the respiratory tract and lead to an asthma attack.

Soda
Soda produces gas, which may apply pressure on the diaphragm. The excessive pressure may make it difficult to breathe, worsening the symptoms of asthma and other respiratory disorders.

Bread
Bread is a wheat-based product that may also cause allergic reactions because of its gluten content. Those allergic to gluten are likely sensitive to albumin and globulin. These are amino acids that lead to inflammation in the respiratory tract and subsequently cause an asthma attack.

Dried fruits
Despite their healthy nature, people with asthma must avoid dried fruits. They contain sulfites that keep the food fresh. However, such preservatives may worsen respiratory symptoms in people with asthma.

Milk
People with asthma should avoid milk or milk-based products. Studies show that milk increases mucus production in the body. Since people with asthma already produce excess mucus in the lungs, milk will only increase their chances of severe respiratory symptoms.

Shrimp
Shellfish are likely to increase the risk of asthma attacks in people allergic to seafood. Shrimp contains sulfites, a property to which many asthma patients are sensitive. Other seafood options people with asthma should stay away from include clams and oysters.

Mushrooms
Mushrooms are a kind of fungi with links to mold and mildew. So those affected by airborne allergens should consider keeping mushrooms out of their meals. Individuals sensitive to the food should also avoid products like mushroom-blended sauces as even they can worsen respiratory issues.
