FAQs
What is the most common food intolerance?
When testing children in 2016 the most common food intolerance was dairy products, with orange and cocoa in second place. In 2026 a favourite fruit is first, cocoa is second, sunflower and orange are third. Dairy product intolerance has changed from 80% of children in 2016 to 12% in 2026.
Most common food intolerances in adults in 2016 were dairy products and yeast. In 2026 dairy products only affect 8% of my adult clients, yeast 10%, but tea and coffee have risen massively. 2 out of 3 adults I test react adversely to their favourite hot drink. Intolerances build up to foods and drinks most frequently consumed.
I’m sure that something I am eating has caused me to put on weight, as I don’t eat much and do a lot of exercise. Can you help?
I have anecdotal evidence that suggests that some people manage to lose weight when avoiding foods to which they are intolerant. But I cannot promise.
I swear that my IBS began after I had the flu. Might this be correct?
My doctor says that there is no cure for my son’s eczema. We must keep using steroid creams and moisturisers.
Avoiding foods to which he is intolerant, changing products which touch his skin, and taking a zinc supplement gives him a chance of 95% improvement.
I have been diagnosed with IBS. My doctor implies that I just have to get on with it.
IBS stands for irritable bowel syndrome. It is not actually a diagnosis as such, but a term that is used when doctors suspect, [or have concrete proof from endoscopy, colonoscopy or blood tests] that there is no serious disease involved. The irritant is very likely to be something that you are eating or drinking regularly.
Improving your microbiome can also help. I can advise on this at the testing session.
My six year old son is so stroppy, argumentative and sometimes downright miserable. We aren’t coping well and now his teacher has requested a meeting.
Causes of children’s behaviour problems are multi faceted. I presume that you try to be very consistent in regard to your expectations for his behaviour? If his behaviour is down to a food intolerance, he is very likely to be suffering other symptoms like tummy aches, headaches or eczema as well. Does he have dark shadows under his eyes? As this is the classic sign that he is eating something to which he is reacting. Vitamin and mineral deficiencies are very often implicated too.
I am 28, and keep getting really horrible spots. Might this be down to a food intolerance?
My mother thinks that my cola drinking habit [5 cans a day] is the cause of my frequent headaches. But if I don’t drink it my headache is much worse.
Mothers don’t always know best, but in this case I think that she may well be right. Either do cold turkey, and go to bed in a darkened room for 3 or 4 days, or give up gradually. …one can less every day until you are not drinking it any more. There may be other foods involved too though, and vitamin deficiencies can also be implicated.
My 3 month old baby has evening colic and eczema. But I am breastfeeding her.
She will be reacting to something in your diet. Get in touch and will get to the root of the problem.
I swear that all my problems are because of the menopause, but my best friend thinks that I should get your advice.
Isn’t everyone intolerant to some food or other?
My tummy is in an awful state. I need to go three or four times before I leave for work, and urgency is causing me to sometimes have accidents. Colonoscopy was normal. My tummy was no problem on holiday in Thailand.
Finding out which foods you react to will sort your symptoms out. Thai diet is very different to a western one, so you were probably not eating the food to which you react or maybe a hot drink?
