Migraines, Headaches and Food Intolerance

The relationship between Migraines, Headaches, and Food Intolerance.

If you suffer from Migraines or headaches, and have not yet discovered a cause then it is possible that you could be one of the estimated 9 million(1) adults in the UK with a food intolerance.

These food sensitivities can be very difficult to pinpoint – often a trial and error elimination diet alone can take months before trigger foods are identified, as your migraines could be due to a food you have just eaten, or it could be because of a food you ate earlier in the day, or even one or two days previously.

Smartblood Story - Julia's Migraines

Julia is a market trader, and also studying speech and language therapy. Julia has suffered with regular migraines for over 22 years, and has tried everything to get rid of them, even ice baths!

It wasn’t until Julia had a Smartblood food intolerance test recommended to her by one of her friends that she found out that she had raised IgG antibody levels to many dairy products. Replacing these foods with others on the advice of a Smartblood nutritional therapist has made a big difference in Julia’s life – her migraines have vanished, and she would recommend a Smartblood test to anybody.

I was getting awful Migraines every week. I took the Smartblood test, changed my diet, and now I don't get Migraines - It's amazing! - Julia

Smartblood could help you identify the cause of your migraines

Smartblood Laboratories are Food Intolerance Specialists. We provide you with an accurate IgG reaction testing service based upon a 45 year old Laboratory method known as ELISA Plate Testing.

By testing a small sample of your blood, we will show you your IgG reactions to 134 food and drink ingredients – if you test positive to any of them then research shows that it is possible that you have a sensitivity to that food type. By eliminating that food type with the help of one of our nutritional therapists you could take control of your Migraines.

Instant Results Access

At Smartblood, we know how frustrating it can be waiting for a postal copy of your food intolerance test to arrive, especially if you are keen to know what trigger foods could be responsible for how you are feeling.

As soon as full Smartblood programme results have been approved for release by our Laboratory Director your full results report will be sent to you via email. View a summary of all reactive food groups and delve further in with interactive charts for each food or drink section, including one specifically for wheat, gluten, and other grains.

Matt's Food Intolerance to Gluten

Maggie's Story - Food Intolerance and Fatigue

The science behind the story.

It is well-known that specific foods trigger migraine attacks in some patients. We aimed to investigate the effect of diet restriction, based on IgG antibodies against food antigens on the course of migraine attacks in this randomised, double blind, cross-over, headache-diary based trial on 30 patients diagnosed with migraine without aura. Following a 6-week baseline, IgG antibodies against food antigens were detected by ELISA. Then, the patients were randomised to a 6-week diet either excluding or including specific foods with raised IgG antibodies, individually. . . Summary - Determination of specific IgG to a large number of foods is an ideal tool to detect individually suspected food and enables a modification of nutritional habits in order to prevent chronic inflammation and onset of migraine in sensitised patients. This is the first randomised, cross-over study in migraineurs, showing that diet restriction based on IgG antibodies is an effective strategy in reducing the frequency of migraine attacks.
