I bought my husband allergy/food intolerance testing for Christmas last year! I know but weve been married so long its hard to be original these days. Even whackier (you may think) it came as a result of having a reading with a medium. She kept saying my hubby wasn't well and suggested something wasn't agreeing with him (probably me).
When he returned from his test I fully expected him to confirm problems with salad veg (especially rocket which lives up to its name). No, suspiciously this was fine!?!? He had the most common result - stay off the cows milk and cheese and forget tea and coffee. So he now drinks rooibis tea with goats milk and I can state categorically that he is still the same, down, miserable, and 'not quite well' so and so he was before.
I can also say that its worth paying the extra for his new tea and milk because the flatulence is markedly improved.
