How Many Salicylates (mg) Do I Eat in a Day?

After reading a study that did not support that reducing salicylates can improve Irritable Bowel Disease or Crohn’s Disease (which is ok!), I became curious about the numbers provided, and where my daily amount fits into the story. The Sivagnanam study (link below) was a survey and feasibility study to see as patients decreased their dietary salicylates if respiratory or digestive symptoms improved. I became very curious because it seemed like the numbers were quite high still, and I wonder if a therapeutic dose is needed (or maximum) to improve symptoms.

In the study, the range varied for patients between 1mg and 120mg a week, with the average at 31.7mg (Ulcerative colitis) and 22.7mg (Crohn’s Disease). After calculating my daily consumption, my weekly amount (using Swain to match their standard) would run less than 0.5mg/week. For perspective, a baby aspirin is 80mg. I know that bumping up higher than 2-3mg/week would bring my irritable bowel symptoms back. On studies like this, I would have loved to see if people actually tried a low-salicylate diet to see if symptoms improved – but surveys and active studies are quite different.

Here are the tools I used to do the calculations:
