The link between high fat foods and asthma

The following is from healthcentral.com/asthma.

"Can Eating High-Fat Foods Trigger Asthma?" (originally published on 5/3/11)

American's love Big Macs, Whoppers, French fries, onion rings and deep fried chicken.  These are convenient foods that are simply delicious.  Yet the old saying goes, "If it tastes good, it's probably not good for you."

Now we already knew such high-fat foods are bad for your heart.  Yet new evidence suggests they may also be bad for your lungs.

A study completed by Australian researchers in 2010 tested asthmatics before and after eating a meal, and determined that lung function was worse after eating a high-fat meal.

If that wasn't bad enough, the study also concluded that high-fat foods also made it so asthma rescue medicine (like Albuterol) worked less well.

Scientists aren't sure why this is, yet there are theories.  One theory suggests that your asthmatic immune system might recognize saturated fat as an enemy and promptly acts to rid it from your system.

This response results in an increase in markers of inflammation such as leukotrienes and hystamine, and these increase inflammation in your respiratory tract.  This causes muscles lining your air passages to constrict, and thus an asthma attack is the result.

Perhaps due to the increased inflammation, asthmatics who used their rescue medicine after eating a high-fat meal did not get as much relief as those who ate low-fat meals.   Likewise, lung function improved less in subjects who used their rescue medicine after eating high-fat meals.

Obviously asthma rates have increased incrementally in the U.S. and other western nations over the past 20 years.  This new theory suggests one of the factors might be the high-fat foods we put into our bodies.

I've also read other studies that suggest that if you're exposed to something that triggers inflammation in your lungs, and exposed to it often enough, the inflammation may become permanent.  Thus, asthma is developed.

It's studies like this that remind us that the way we eat may determine the lives we live.  If you want to prevent asthma, or prevent an asthma flare, it may be a good idea to eat a healthy diet.

Does that mean we asthmatics should never eat great tasting, convenient and high-fat foods?  Absolutely not.  Yet it's good to know the facts, and it's good to know what foods might not be good for us.

I just discovered, on my own, the link between high fat foods and asthma...it's astounding...quite literally, the direct correlation. I should be used in a study.

I had ongoing asthma for the past 5 years. I inhaled Advair twice a day for years as well as having to do nasal steroids as well for what appeared to be allergies.

About 5 months ago, i went on a very wonderful very low fat diet--I do eat a little fat, and carbs, and gluten, but not too much... and in addition to losing weight and feeling great, my asthma disappeared completly. I mean...COMPLETELY. And the result was immediate--as in, within 3 days of starting the diet. I didn't correlate dietary fat to asthma, though, even then. But a few days ago, I went on a date out to eat a very high fat Mexican dinner.

A little while later, that same night, I had an asthma attack. The first in 5 months. And not a little one. A biggie. I felt TERRIBLE. I also had certain other gastric reactions that I also never have.

So after the attack, I checked the research linking high fat meals to asthma, and I found the study to which you refer. IT IS SO TRUE FOR ME. I'm sure other people have asthma for other reasons, but for me, it is absolutely linked to saturated fat.

I'm wondering if my body, wisely, sees saturated fat as the enemy and tries to expel it like an allergen.

Well, I absolutely feel that this is the best thing that could have ever happened to me...asthma sucks enough for me that I will never feel the need to eat high fat meals again. Or if I do, in VERY small portions (though I don't know what the limit will be--I will have to experiment, I suppose).

I think if you have an allergy, FAT is a good one to have.

Thank you for posting! Hopefully other people will see the link as clearly as I do!!!
