But what is the most common food allergy?

It is difficult to pinpoint the number 1 most common food allergy, but peanut and milk allergies are the most common cause of food allergies in the UK.

Peanut allergy affects around 2% (1 in 50) of youngsters in the UK and has been on the rise in recent decades. It normally appears in early childhood, however it might arise later in life on rare occasions.

Did you know; peanuts are a legume and are from a different family to tree nuts. In many cases, this can mean that the individual suffering from a peanut allergy can eat tree nuts without any reaction but, in other cases, they can be allergic to both peanuts and some tree nuts.

Cow’s milk (protein) allergy (CMA or CMPA) is one of the most frequent food allergies in infants and children. By the time they reach school age, most children will have outgrown their milk allergy (around 5 years of age), as adult onset cow’s milk allergy is extremely rare.

In the UK, an estimated 6-8% of children up to the age of three years have a food allergy, whilst around 2 million+ people are currently living with a diagnosed food allergy, although this number could be much higher in reality.

Parents often get confused between a Food allergy and Food Intolerance. Food intolerance is simply when the body cannot properly digest the food and irritates the digestive system causing various symptoms such as nausea, bloating, loose stools, tiredness e.t.c. Whereas, in the case of a food allergy the body’s immune system attacks the food causing histamine to be released in the body. The reactions can lead to various symptoms such as hives, itching, eczema, throat tightness, abdominal pain, vomiting e.t.c.
