Prioritization of Food Allergens in Saudi Arabia Using a Multi-Criteria Profiling Model
This study utilizes a multi-criteria profiling model to rank food allergens in Saudi Arabia, identifying eggs, dairy, and peanuts as the highest-risk allergens to inform evidence-based food safety regulations and policies.

Food allergy is a complex immune reaction where the body mistakenly identifies a harmless protein in food as a dangerous invader, triggering symptoms that can range from a mild rash to a life-threatening emergency. Because these reactions are so serious, governments around the world maintain lists of specific foods that must be declared on packaging, ensuring that people with allergies can avoid them. However, the foods that appear on these lists are not the same everywhere. What causes the most trouble in one country might be rare in another, depending on local diets, genetics, and how often people eat certain items. To protect public health effectively, regulators need to know which allergens pose the greatest risk to their specific population, rather than simply copying lists from other nations.
In Saudi Arabia, researchers set out to create a more precise ranking of the top ten food allergens affecting the adult population. Instead of relying on a single number, such as how many people say they are allergic, the team built a computer model that weighed three different factors together. First, they looked at how likely a person is to encounter the food in their daily diet, considering how much of it is eaten and how often. Second, they considered the potency of the allergen, which is a measure of how little of the substance is needed to trigger a reaction in a sensitive person. Third, they incorporated data on how many people in the country actually have a confirmed allergy to that specific food. By combining these elements, the model could estimate the total number of allergic reactions that might occur for every 100,000 people who already have food allergies.
The results of this simulation revealed a clear hierarchy of risk. Eggs emerged as the most significant allergen, predicted to cause the highest number of reactions, with an estimated 31,291 cases per 100,000 allergic individuals. Dairy products followed closely in second place, with about 23,982 cases, while peanuts took the third spot with roughly 12,900 cases. At the other end of the spectrum, shrimp, soy, and sesame were ranked as the lowest risks, with sesame showing the fewest expected reactions at around 2,605 cases per 100,000. The study found that while the top three allergens remained consistent across different ways of measuring risk, the middle of the list shifted depending on which factor was emphasized. For instance, wheat and fish appeared much higher when the model focused purely on how often people eat them, reflecting the country's heavy consumption of these foods, even though fewer people are allergic to them compared to eggs or milk.
This approach challenges the idea that a single statistic, like the percentage of people who report an allergy, is enough to determine safety priorities. The researchers noted that while sesame is a major concern globally due to its ability to cause severe reactions in very small amounts, it ranked last in this specific Saudi context because it is less common in the local diet and affects fewer people overall. Conversely, the high ranking of eggs and dairy was supported by both local survey data and global patterns, giving the team confidence that their model accurately reflects the reality of food safety in the region. The study concludes that using this multi-faceted view provides a stronger foundation for updating food labeling laws and managing allergen risks, ensuring that regulations are tailored to the actual dangers faced by the population rather than generic international standards.
