Ninety percent of food allergies are linked to just eight foods: milk/dairy, eggs, fish, shellfish, tree nuts, peanuts, wheat (gluten), and soybeans. Unfortunately, most of these are commonly used in food production, and in ingredients formulation, and we know how important it is for consumers to feel comfortable when consuming specific foods and beverages. Furthermore, there is a wide variety of voluntary diets that have risen to fame in recent times, such as vegan-vegetarian, keto, paleo, low-carb, pregnancy, etc. These are not always linked to specific food allergies or intolerances but can restrict a similar if not greater range of foods and ingredients. Last – but not least – in addition to ingredient sensitivities and lifestyle choices, there are religious reasons that prohibit certain foods, or require special processing methods. Certain religions consider pork as impure, others exclude alcohol, and a few have mandatory rules about food preparation and ingredient segregation.
