Asthma is a chronic respiratory disease that affects millions of people around the world. It is a condition characterized by inflammation and narrowing of the airways, resulting in difficulty breathing.

While there are many triggers for asthma symptoms, including exercise, cold air, and pollution, diet can also play a role. This article will explore the link between diet and asthma symptoms, and offer some dietary recommendations for those suffering from asthma.

The Link Between Diet and Asthma Symptoms

Research in recent years has suggested that certain foods and nutrients can either trigger or alleviate asthma symptoms.

For example, studies have found that a diet high in fruit and vegetables can decrease the risk of asthma, while a diet high in processed and fast foods can increase the risk (1).

Processed Foods and Asthma

Processed foods refer to foods that have been altered from their natural state in some way, usually through the addition of preservatives, artificial flavors or colors, or other chemicals.

Examples of processed foods include fast food, snack foods, and packaged meals.

Studies have found that people who consume a diet high in processed foods are more likely to experience asthma symptoms.

One study of 47,000 children found that those who consumed fast food more than three times per week had a 39% increased risk of asthma compared to those who rarely ate fast food (2).

Another study found that high intake of processed meats was associated with an increased risk of asthma symptoms in children, while a high intake of fruits and vegetables was associated with a decreased risk (3).

The Role of Antioxidants in Asthma

Antioxidants are compounds found in many fruits and vegetables that help protect against oxidative stress, a process which can cause inflammation and damage to the body’s tissues.

Studies have found that a diet high in antioxidants may help reduce asthma symptoms.

One study of 68 asthmatic adults found that those who consumed a diet high in fruits and vegetables had fewer asthma symptoms, as well as better lung function, compared to those who consumed a diet low in fruits and vegetables (4).

Another study found that children who consumed a diet high in antioxidants had a lower risk of developing asthma (5).

Foods to Avoid

While the link between specific foods and asthma symptoms may vary from person to person, there are some foods that are more likely to trigger asthma symptoms than others. These include:.

  • Processed foods
  • Fried foods
  • Salty foods
  • Sugar and sugary drinks
  • Dairy products
  • Alcohol

Foods to Include

While there is no specific “asthma diet,” there are certain nutrients and foods that may help alleviate asthma symptoms. These include:.

  • Fruits and vegetables
  • Whole grains
  • Lean proteins, such as fish or poultry
  • Healthful fats, such as those found in nuts, seeds, and avocados
  • Foods high in vitamin D, such as salmon or fortified dairy products

The Importance of Hydration

Staying hydrated is important for overall health, but it can be especially important for people with asthma. Dehydration can cause the airways to narrow, leading to increased difficulty breathing.

It is recommended that adults consume at least eight 8-ounce glasses of water per day, and children should aim for at least six glasses (6).

Conclusion

While there is no magic diet for asthma, research suggests that a diet high in fruits and vegetables, and low in processed and fast foods, may help alleviate symptoms.

Additionally, staying hydrated and avoiding certain foods may also be helpful for those with asthma. If you suffer from asthma, talk to your doctor about creating a personalized diet plan to help manage your symptoms.
