What helped for people with severe food intolerances

The 2 most popular diets and anti-histamines tended to have bigger results in people who reported severe suffering from food intolerances. DAO enzymes and plant-based/vegan diets were an exception… results were roughly the same regardless of severe food intolerance.

The chart includes some treatments which very few people reported results for:

  • Other antihistamines - 7 in severe, 9 in mild or no food intolerance
  • Hydroxyzine - 9/13
  • Clarinex - 9/9

Some treatments had decent sample sizes:

  • Acrivastine - 25/31
  • DAO - 28/18
