Britons are being warned of a concerning rise in novel food allergies, with adults unexpectedly developing reactions to everyday foods that were previously tolerated. This emerging health trend is putting a new strain on individuals and the NHS alike.
Leading the research into this phenomenon is Professor Alex Richter from the University of Birmingham. Her team's work has identified several surprising allergens becoming increasingly common.
The Unlikely Culprits
While peanuts and shellfish remain top allergens, Professor Richter's research highlights a shift towards more unusual triggers. Among the most notable are:
- Goat's milk
- Pine nuts
- Buckwheat
- Lupin flour
- Kiwi fruit
"We're seeing more adult-onset food allergies than ever before," Professor Richter explains. "Patients are reporting reactions to foods they've eaten without issue for years."
Why Are These Allergies Emerging?
The precise reasons behind this increase remain complex and multifaceted. Experts point to several potential factors:
- Changes in modern farming and food processing methods
- Increased consumption of previously exotic foods now mainstream in UK diets
- Environmental factors and climate change affecting pollen counts
- The 'hygiene hypothesis' suggesting overly clean environments may prevent proper immune system development
Professor Richter emphasises the seriousness of these conditions: "Food allergy is not a trivial matter; it impacts every aspect of an individual's life, from eating at restaurants to shopping for groceries."
Recognising the Symptoms
The symptoms of these novel allergies mirror traditional food reactions and can include:
- Swelling of the lips, face or eyes
- Digestive discomfort including vomiting or diarrhoea
- Difficulty breathing or wheezing
- Dizziness or lightheadedness
- Anaphylaxis in severe cases
Experts urge anyone experiencing these symptoms after eating to consult their GP and request a referral to an allergy specialist for proper testing and diagnosis.
As research continues, one thing remains clear: the landscape of food allergies in Britain is changing, and public awareness needs to evolve alongside it.
