Although there is no cure for asthma, you can certainly take steps to control it. We find that many asthmatics wonder if their diet affects their asthma. To answer their questions, let’s look at what are the best and worst foods for asthma, and whether diet has a long-term impact on your health? 

Does Your Diet Affect Your Asthma?

Your diet plays a significant role in your overall health and comfort, especially when balanced with proper exercise and medication. Certain studies indicate that people who eat a healthy diet may be less susceptible to asthma than those who don’t. Additionally, depending on your allergies or sensitivities, some foods (and food groups) have been known to cause harmful reactions that could trigger your lung condition.

In a nutshell, your diet is important enough for your lung health to warrant a good, hard look. Make sure you know which foods are best for your asthma, as well as which foods are the worst.

Best Foods for Your Asthma

Again, there is no “superfood” that will prevent you from getting asthma or cure your asthma. However, the following foods can increase your immunity, boost your overall health, and possibly reduce the number of asthma attacks.

  • Vitamin C Fruits

This probably isn’t the first time you have heard about the merits of vitamin C. Not only do Vitamin C foods (specifically fruit) provide important antioxidants that fight off a lung infection, they also protect you from getting sick. Normal respiratory infections often trigger asthma flare-ups, so the less you get sick, the better your lung health. Citrus fruits are particularly high in Vitamin C.

  • Carrots

Carrots contain beta-carotene, which changes to vitamin A in the body and helps the body cope with physical activity and increased blood flow. For those who suffer from exercise-induced asthma, carrots make a great dietary staple.

  • Caffeine

Did you know that caffeinated beverages can help your asthma? That’s right, no need to eliminate coffee. Some studies indicate that caffeine might improve your muscle oxygen saturation after it is ingested. Just be careful not to make yourself jittery, or you might trigger an anxiety asthma attack.

  • Garlic

Garlic has long been a home remedy for ear infections, colds, and more. However, did you know its healing properties lie in its allicin content? Allicin is an antioxidant that aids in the strengthening of your immune system and in the overall protection of your body. It can help fight viruses that might lead to asthma flare-ups or other health concerns.

  • Flax

Although there is no direct link between asthma and flaxseed, flaxseed is high in healthy fats and is extremely good for your general diet. Additionally, it might relax your bronchi, which prevents your lungs from becoming inflamed.

  • Avocado

In recent years, avocado has emerged as somewhat of a superfood. It is full of healthy fat that lowers your cholesterol and promotes healthy skin, hair, and immunity. 

Worst Foods for Your Asthma

On the other hand, some foods act as natural triggers for those with chronic lung conditions. If you have asthma, take care to ensure that you do not possess a sensitivity to any of the following foods.

  • Peanuts
  • Salt
  • Shellfish
  • Dairy
  • Alcohol

Dairy and alcohol are particularly common asthma triggers. Many people possess a dairy sensitivity without even realizing it, and regular alcohol consumption can trigger asthma for several reasons.

Additional Tips to Keep in Mind

Remember, the best way to keep your lungs healthy is to keep the rest of your body healthy. A healthy diet and regular exercise (based on the instructions of your doctor) go a long way in improving overall health and stamina. Overly processed foods with extra fat, sodium, etc. often make you feel sluggish and unmotivated, reducing your health.

Remember that your body is merely a vehicle run by your mind. Just as important as bodily health is mental health. When both are in balance, you will find that it is far easier to maintain control of your asthma symptoms and triggers.
