Asthma and diet linked again

I cured my asthma through changing my diet and lifestyle.  The scientific proof of what I did just keeps on coming.

“We really do promote this as a healthy way to change your lifestyle which will improve asthma but also which will improve your overall health status.  We’ve seen that fruit and vegetables can be very helpful, so if you have a diet that’s high in fruit and vegetables compared with a diet that’s low in fruit and vegetables, that reduces your risk of having an asthma attack.  The usual diet consumed by asthmatics in this study was pro-inflammatory relative to the diet consumed by the healthy controls...  Hence, consumption of pro-inflammatory foods in the diet may contribute to worse asthma status.  Previous research had shown that eating a single high-fat meal could cause inflammation in the airways of people with asthma.  The body responded to an excess of dietary fat in the same way it would an invading pathogen, and if you chronically eat like that, your immune system will be chronically activated.  It is particularly important for people who already had asthma to eat a diet high in fruit and vegetables and low in saturated fat and takeaway foods”
University of Newcastle Nutritional Biochemist Lisa Wood, April 2014.

The study looked at inflammatory-causing foods (such as refined sugar and animal proteins/fats) and also inflammatory-lowering foods (such as fruits, vegetables, wholegrains and legumes), and compared the diets of asthmatics vs non-asthmatics and monitored inflammation and asthmatic attacks. 

The researchers found:

  • Asthmatics were eating far higher amounts of the ‘inflammation causing’ foods than those without asthma
  • Asthmatics were experiencing more asthmatic attacks on the inflammation-rich diet
  • People who eat diets high in saturated fats (animal foods) are more likely than others to have asthma attacks
  •  For every 1 unit increase in DII score (an inflammation measure), the odds of having asthma increased by 62%
  • The higher the DII score, the worse the lung function
