Asthma is a chronic disease that inflames and narrows the airways in the lungs. Unfortunately, asthma afflicts 300 million people worldwide. It usually requires prescribed medicine. The good news is that there are some lifestyle interventions that can help you control it better.
Avoid High-Fat Meals
Why? Individuals with asthma who consume a high-fat meal show increased airway inflammation just hours after the binge. A high-fat meal also appeared to inhibit the response to the asthma reliever medication, Ventolin (albuterol).1
Eat Fiber, Especially Insoluble Fiber
Insoluble dietary fiber plays a vital role in the immune system. The fiber in the diet increases the level of short chain fatty acids. These beneficial fatty acids help to reduce inflammation.2 Bacteria and fungi in the gastrointestinal tract can intensify the immune system’s reaction to common allergens (like pollen or animal dander) in the lungs and increase the risk of developing chronic allergies or asthma.3 As long as the balance of gut microflora remains stable, tolerance to allergens continues. But anything that alters this intestinal balance – taking antibiotics, NSAIDS (non-steroid anti-inflammatory drugs), switching from breast milk to formula, eating a high-sugar, low-fat diet — interferes with the balance of gut bacteria so that friendly bacteria are suppressed and unfriendly bacteria multiply. Fiber encourages favorable conditions so the friendly bacteria can increase and curtail inflammation.
Check your Diet for Adequacy
A low dietary intake of fruit, vitamins C and E, and omega-3 fatty acids have been linked to decreased lung function and a greater risk of chronic bronchitis symptoms and asthma. These risks are further increased among students with these lowest intakes, and who also smoked.4
A low dietary intake of antioxidants and anti-inflammatory nutrients and phytochemicals enhances the likelihood of respiratory symptoms such as asthma, especially in teens who smoke. Research shows that higher intakes of antioxidant and anti-inflammatory micronutrients are linked to lower reports of coughing, respiratory infections, and less severe asthma-related symptoms.5 Remember that the anti-oxidant nutrients such as vitamins D, E, C, riboflavin, and zinc work in synergy with the anti-oxidant compounds found in whole foods. A supplement may help but it does not contain the broad variety of anti-oxidant and anti-inflammatory compounds that whole fruits and vegetables do. Smoking and sugar consumption lower the antioxidant level in the body.
Omega-3 fats, such as found in chia and flaxseed, provide some protection. Taking certain omega-3 fatty acid supplements during pregnancy can reduce the risk of childhood asthma by almost one third.6
Stay Away from Junk Foods
Limit your intake of processed foods. A high level of soft drink consumption is associated with asthma and chronic obstructive pulmonary disease.7 Fortunately, a high fiber diet reduces the cravings for junk food.
People who ate the most fast food had phthalate levels that were as much as 40 percent higher. Phthalates belong to a class of industrial chemicals used to make food packaging materials, tubing for dairy products, and other items utilized in the production of fast food. Accumulating research suggests that these chemicals can leach out of plastic food packaging and can contaminate highly processed food. Previous studies have shown a link between high-molecular-weight phthalates and allergic disease development. Epidemiological studies have also shown that exposure to house dust containing several of these chemicals is associated with asthma and allergic disease.8,9
Lose Weight if Obese
Extensive research shows that obesity can cause narrowing of the airways in the lungs. Studies show the prevalence of asthma is higher by 38% in overweight patients and by 92% in obese patients.10 When obesity develops in people with asthma, it aggravates the breathing disorder. Obese patients with asthma also get more acute attacks, need more asthma medication, need more frequent visits to the emergency department, and have more hospital admissions than non-obese patients with asthma. Weight loss may be a useful strategy to reduce the severity or reverse asthma in obese individuals.11
Check your Vitamin D Level
Low blood levels of vitamin D have been linked to an increased risk of asthma attacks in children and adults with asthma. The Cochrane Review has found evidence from randomized trials that taking an oral vitamin D supplement in addition to standard asthma medication is likely to reduce severe asthma attacks. Vitamin D supplementation significantly reduced the rate of asthma attacks needing treatment with steroid tablets.12
Learn How to Manage Stress
Several studies have linked symptoms of depression to asthma. Stress and depression aggravate asthma. Focusing on and enjoying what you actually can do, instead of fretting on what you can’t do, helps. Cultivating a regular schedule for meals, retiring and waking up helps to improve one’s overall health. Therapeutic massage can help reduce stress and relax the muscles that assist in breathing.
Pollen is not the only cause of asthma. Food allergies can provoke asthma too. You want to avoid any dietary triggers.
