France Allergy Crisis: Causes, Diagnosis & New Food Allergies
Allergies are on the rise in France, affecting an estimated 30% of the population, and increasingly presenting as complex medical mysteries, according to Dr. Catherine Quéquet, an allergologist and medical journalist. Quéquet describes her work as akin to a police investigation, requiring detailed timelines and even inquiries into patients’ personal lives to identify triggers.
The increasing prevalence of allergies is linked to modern lifestyles, including the overuse of cleaning products, the prevalence of composite building materials, and inadequate ventilation, according to Dr. Quéquet. Environmental pollution also plays a significant role, altering pollen composition and increasing its allergenic potency, a problem exacerbated by climate change and extended pollination periods.
Despite the growing need, France has a relatively compact number of dedicated allergologists – approximately 1,200 practicing exclusively in the field. Quéquet points out that allergology is not typically taught during medical school, leaving general practitioners on the front lines of diagnosis and initial management. Professional organizations and patient associations have proposed a plan to integrate allergy education into the medical curriculum.
The diagnostic process, Quéquet explains, can be remarkably intricate. Cases extend beyond typical food and environmental allergies to include unusual reactions, such as allergies triggered by beer – sometimes transmitted through kissing – and responses to unexpected sources like proteins in renovation paint or even through skin contact. She recounted a case of an adolescent who developed an allergic reaction after kissing a partner who had recently consumed peanuts.
The rise in food allergies is also prompting innovative culinary approaches. Marie Lossy, a mother from the Gironde region, has developed cooking techniques to manage the 25 food allergies of her child, utilizing methods she describes as “Sioux ruses” in the kitchen. Dr. Quéquet has included Lossy’s recipes in her latest book. Lossy has also worked with allergologists, including Dr. Séverine Fernandez, to demonstrate how to prepare meals without major allergens. Lossy has been creating allergen-free meals for her son for over 21 years, navigating the complexities of avoiding the 14 legally mandated allergens and more.
The changing dietary habits of the population are also contributing to the increase in allergies. The introduction of exotic foods, industrial food processing, and even the consumption of insects are disrupting the gut microbiome, which plays a crucial role in immune regulation and allergy development.
Dr. Quéquet’s work highlights the multifaceted nature of allergies, extending beyond simple avoidance to a complex interplay of environmental factors, lifestyle choices, and individual sensitivities.
