We talk to YorkTest’s nutritional therapist manager Sarah Hughes to find out more.

What does the test do?

“We are testing the protein in the food and if your body produced the IgG antibody to the food.

“When you are allergic to something, the body produces the IgE antibody which is something that’s quite quick and instant. Intolerance is different and it’s not as quick a reaction and can take up to 72 hours.

“With IgG, your body is seeing food as an enemy and it is producing antibodies as a reaction. The intolerance wouldn’t show up if you haven’t eaten something for a couple of months and it doesn’t test for lactose in milk as that is a sugar.

"Some people who don’t know they’ve got an intolerance say they have no symptoms but they come off the foods and say they are sleeping better and have more energy.

Nutritionist Sarah Hughes

What’s my diagnosis?

“You’ve got a few more than average – and cranberry’s quite interesting to be at the top. Yeast is quite high, which is typical in our Western diet as it’s sugary, and yeast can be found in wine, beer and vinegar. I would think someone with that many might suffer from a leaky gut – or it might be brought on by medication.”

So what’s a leaky gut?

“It’s when proteins are getting into the bloodstream that shouldn’t. That causes a reaction – and it’s the IgG reaction. The wall of the gut is only the width of a quarter of a piece of paper and it’s so thin and different medication can cause little holes.

What’s your advice?

“Avoid the foods for three months then re-introduce them really slowly. If it was egg for instance, make a boiled egg and eat it and, if you have no symptoms that week, have two eggs the next on a Monday and Thursday. And still no more symptoms, have them every other day.

“And I’d suggest getting a probiotic for two months to repair the gut with good bacteria. Also, three mugs of herbal tea a day, like chamomile, or just root ginger in hot water, as well as eating anti-fungal ingredients like garlic and cinnamon."

Review

Cranberry topped an extensive traffic light list which also showed severe reactions to yeast, beetroot and kiwi.

In a less-severe shade of yellow, were salmon, sunflower seeds, coconut and gluten.

I expected a strong reaction to dairy milk but there was nothing, although Sarah said this might be because I’d excluded it from my diet.

Aside from that, I’m someone who doesn’t suffer a churning tummy or sharp pains after eating anything in particular.

To discover the detailed outcomes means taking the home test.

It was simple,only takes five minutes and involved a prick of the finger before coating a test stick with droplets of blood.

Then post back and await the findings which were emailed across in a matter of days.

Armed with Sarah’s advice and a YorkTest guidance book I’ve vowed to make some changes.

I’ll be giving up wine and bread for Lent – so that might address wheat and gluten intolerances – while I’ll steer away from cranberries, hemp in my smoothies and, reluctantly, kiwis.
