For the record, actual experts on food allergies and intolerances will tell you that hair testing - bioresonant or not - along with blood tests for IgG response, cytotoxic tests, Vega testing and applied kinesiology - are not proven methods for diagnosing allergies or intolerances.
They are all highly questionable, only reliably proven to part vulnerable people from their money.
And that's what gets me - the way these companies exploit vulnerable people.
Look at that list of symptoms. Lethargy, bloating, headaches, nausea, brain fog. They're catch-all symptoms from which we have all suffered from time to time. They're vague and tricky to attach to a genuine diagnosis, hence probably why many people feel frustrated that the medical system hasn't been able to help them when they present with these issues.
But they do not automatically mean we have a food intolerance. I'd be willing to put money on the fact that no one who signs up for one of these bogus tests ever gets a result back which says "nope, not intolerant to anything". So potentially there are lots of people avoiding lots of foods, at great expense, for no good reason.
Proper diagnosis of food intolerance is difficult and takes time. It involves a properly supervised elimination diet, and the re-introduction of potentially problematic foods. It's not as easy as sending off a bit of hair, unfortunately. But done properly, the results can mean huge improvements for the patient.
With allergies, it's even more important to get properly tested, and to have proper help with the interpretation of test results. Allergy specialists look very carefully at a patient's history and symptoms alongside their test results.
If you're feeling lethargic, bloated or headachey at the moment it's highly likely to be related to the festive season. But if you're having long-term symptoms, I'd suggest you stay away from Google and start with your doctor.
