What is Asthma?

Asthma is considered a chronic inflammatory disorder of the airways. It involves air pathways in the lungs becoming swollen and constricted, resulting in trouble breathing, whistling sounds, and coughing. People with asthma may experience triggers such as pollen or dust, cold weather, exercise, and anxiety.

Patients vary in how severe their disease is, ranging from mild symptoms to life-threatening attacks. There is no cure; however, asthma is treatable with medication and certain alterations in daily habits. Effective management improves overall wellness in the patient.

What is the Connection Between Asthma and Diet?

Food plays an essential role in maintaining our health. In fact, medical researchers have observed that dietary choices are connected with cases of asthma. Often allergens and sulphites are present in food items that people consume regularly. For instance, wine, beer, dried fruits and vegetables, and pickled foods contain sulphites. Please note that consuming foods with too much sulfites can trigger asthma.

It has been observed that obesity might also cause asthma and worsen symptoms of those suffering from it. Consuming fresh vegetables and fruits and exercising regularly go a long way in maintaining our health.

The right food items preserve and improve our health, including the lungs. Dietary changes, along with medications and exercising, can result in significant improvement in the health of those suffering from asthma.

Foods to Avoid for Asthma Patients

Now that we have looked at the food items that are helpful for asthma patients, let us turn our eyes to the food to avoid for asthma patients:

1. Sulfites

These are chemicals that manufacturers add to food items to increase their shelf life, appearance and taste. For example, pickled food items, dried fruits and sauerkraut are high in sulfites. Additionally, regular consumption of alcohol, wine and grape juice can worsen asthmatic conditions. This is because these food items are rich in sulfites.

2. Salicylates

avoid eating salicylates food during asthma

These are naturally-occurring compounds present in coffees, teas, spicy foods and dishes flavoured with herbs. It has been observed that asthma patients are often allergic to salicylates. It leads to flaring up of symptoms.

3. Fast Food

Fast food items contain a high amount of additives, saturated fats and sodium. People who show symptoms of asthma should limit the consumption of fast foods. Otherwise, it might worsen their health conditions.

A 2015 study found that children who consume fast food regularly are much more likely to have asthma.

4. Foods that Cause Gas

avoid foods that cause gas during asthma

There are certain food items like carbonated drinks, garlic, onion, fried foods, beans and cabbage that cause gas. This leads to asthma attacks and chest tightness, which can further make breathing difficult. Bloating can put pressure on the diaphragm and trigger asthma symptoms.

5. Artificial Ingredients

These include chemical preservatives, colourings and flavourings. These are generally found in processed and fast food items. These are harmful to asthma patients. In fact, asthmatic patients may be allergic or sensitive to such artificial ingredients.

Factors to Consider While Choosing Diet for Asthma Patients

It's important to select a diet that aligns with your lifestyle, supports your overall well-being, and is sustainable in the long term. Here are a few following factors involved:

1. Health Problems

Asthma patients may not always suffer solely from asthma. They can also have other underlying issues. Therefore, visiting a doctor and getting yourself checked thoroughly is essential. This will help you understand the extent of your condition.

2. Consult a Professional

Consulting a dietician or nutritionist is always the best way to get a prescribed diet for asthma patients. They are professionals with more knowledge regarding illnesses and how to treat them. They will create a perfect diet chart for you that will be personalized based on your condition, allergies, food preferences, and lifestyle.

3. Your Eating Preferences

You should never force yourself to eat a particular food if you do not like it. It might be healthy for you and even reduce your asthma, but it will deter you from following a diet. As a result, your asthma may again aggravate.

4. Set a Budget

There are many good foods for asthma patients, but they are only sometimes affordable. This is why patients should set a budget so they do not end up overspending on food. Spending more than required on food is unnecessary and adds to stress.

What are the Causes of Asthma?

Asthma is a chronic respiratory condition caused by various factors that lead to airway inflammation and breathing difficulties. These causes include environmental triggers like pollen, dust mites, pet dander, and air pollution. Genetic factors also play a role, as asthma often runs in families.

Respiratory infections, particularly in childhood, can increase the risk. Allergies to certain foods or medications can trigger asthma symptoms as well. Smoking, both direct and secondhand exposure, is another common cause. Physical activity or exercise-induced asthma can also be a factor, especially in cold air.

How to Treat Asthma?

Asthma treatment focuses on controlling symptoms, preventing attacks, and improving quality of life. It involves a combination of medication, lifestyle changes, and avoiding triggers that worsen the condition. Below are key treatment strategies:

1. Inhalers (Bronchodilators and Steroids)

Inhalers are the primary asthma treatment, helping open airways and reduce inflammation. Bronchodilators offer quick relief during an asthma attack, while steroid inhalers control long-term symptoms.

2. Avoiding Triggers

It is crucial to identify and avoid asthma triggers, such as allergens (pollen, dust mites), smoke, or pollution. Reducing exposure to these irritants can significantly decrease the frequency and severity of asthma symptoms.

3. Medications (Long-term Control)

Oral medications like leukotriene modifiers or theophylline help manage asthma over time. These medications reduce inflammation or relax airway muscles, providing long-term control for people with persistent symptoms.

4. Lifestyle Changes

Incorporating a healthy diet, regular exercise (under medical supervision), and stress management techniques can help improve lung function and overall asthma control. Avoiding smoking or secondhand smoke is also critical.

5. Emergency Action Plan

An emergency asthma action plan helps patients manage severe asthma attacks. This plan should include steps to take when symptoms worsen, when to use rescue medication, and when to seek medical help.

How to Prevent Worsening of Asthma Symptoms?

Patients who have asthma need to identify and stay away from triggers that may worsen their condition. Listed below are a few things that people need to do to prevent the worsening of their health condition:

Stay away from smoke, including cigarette smoke, burning wood, and campfires.
Avoid adverse weather conditions like stormy, humid, cold, or windy weather.
Reduce exposure to air pollution, vehicle exhaust fumes, chemical fumes, and smog.
Minimizing exposure to dust mites or spores is also a good idea.
Avoid common food allergens like shellfish and peanuts.
Finally, avoid over-the-counter (OTC) medications like non-steroidal anti-inflammatory drugs and aspirin.

What are the Key Points to Remember?

Maintaining a healthy diet is essential to keep your asthma in control, but you should also keep the following points in mind:

Identify what is triggering your asthma. It can be anything, starting from sinusitis to smoke to air pollution.
