Are Food Intolerance Tests Accurate? My Honest Review After 4 Weeks

4 min readSep 4, 2025

So I’m back with part two of my Bioresonance food intolerance testing review. It’s now just over a month since I first tried the test, and today I want to share what happened when I actually followed through and cut out the foods that came up on my results and to see if food intolerance tests are accurate?

If you haven’t read part one yet, you can find it here: Food Intolerance Testing Review — My Experience

In that first post, I explained how the test worked (it’s simply done with a strand of hair) and what my results showed. In this follow-up, I’ll be diving into whether taking those foods out of my diet actually made a difference — and ultimately, answering the question: are food intolerance tests accurate?

Why I Tried a Food Intolerance Test

At 42, navigating perimenopause with PCOS, I’ve been experiencing some pretty frustrating symptoms:

  • Brain fog and tiredness
  • Significant bloating, especially after certain meals, to the point I can look nine months pregnant
  • Joint pain and inflammation, including golfer’s elbow and achy knees
