How Allergies and Dietary Restrictions Are Shaping the Creation of New Menus

Over the past decade, the culinary world has seen a significant shift—not just in tastes, but in the very foundation of how menus are created.

A growing number of diners now arrive at restaurants with a clear list of ingredients they can’t or won’t eat, whether due to medical conditions, religious beliefs, or lifestyle choices. From gluten intolerance to kosher guidelines, dietary restrictions are no longer a niche consideration; they are driving innovation, conversation, and sometimes even frustration in professional kitchens.

Food allergies and intolerances are on the rise worldwide. In Europe, it is estimated that around 17 million people suffer from food allergies, with children making up a significant portion of this number. In the United States, the Centers for Disease Control and Prevention (CDC) reports that food allergies in children increased by 50% between 1997 and 2011, and today affect approximately one in 13 children, or roughly two students per classroom. Adults are not far behind, with the Food Allergy Research & Education organization estimating that over 33 million Americans have food allergies.

But the challenge for restaurateurs goes beyond food safety. A growing wave of international travelers—particularly from the Middle East, South Asia, and other regions—brings with it religious and cultural dietary restrictions that require attention and sensitivity.

Muslims may require halal meat and avoid pork and alcohol, Hindus typically avoid beef, and Jews following kosher laws must steer clear of shellfish and pork and often have specific food preparation requirements. These restrictions are non-negotiable and can’t be addressed with a simple menu swap.

The hospitality industry is under pressure to offer more inclusive options.

As a result, the hospitality industry is under pressure to offer more inclusive options—without compromising authenticity. Can you truly serve a classic Carbonara without guanciale? Is a vegan croissant still a croissant? Chefs are grappling with these kinds of questions in an era where flexibility is key, but tradition still matters.

To complicate matters further, not all guests fully understand the difference between an allergy, an intolerance, and a personal preference. Some claim to be allergic to gluten, only to order a beer with their meal. Others confuse dairy-free with lactose-free, unaware that butter may still be present in “non-dairy” dishes. For chefs and servers, this can lead to confusion, stress, and even potential liability.

Despite the challenges, there’s a silver lining. This new dietary awareness wave pushes restaurants to be more creative, transparent, and connected to their customers’ needs. Menus are being rewritten with symbols, allergen keys, and detailed ingredient descriptions.

Front-of-house staff are better trained, and back-of-house operations are more meticulous than ever. What might have started as a headache is now becoming an opportunity for innovation and inclusivity.
