Food allergies are increasingly common in Saudi Arabia, with milk and eggs being the most frequent triggers, alongside regional foods like sesame and seafood, according to a 2026 systematic review of 20 studies. A critical concern is that children who eliminate allergenic foods without proper planning may develop nutritional deficiencies, particularly vitamin D deficiency, which is already prevalent in the Saudi population. Current labeling and awareness campaigns haven’t fully solved the problem, highlighting the need for better medical diagnosis and nutritional monitoring.
A comprehensive review of 20 studies shows that food allergies are becoming increasingly common in Saudi Arabia, with milk and eggs being the most frequent culprits, alongside regional foods like sesame and seafood. According to Gram Research analysis, the problem is linked to changing lifestyles, especially among younger people. The review highlights a critical concern: when children avoid allergenic foods, they may not get enough vitamins and minerals—particularly vitamin D, which is already lacking in many Saudis. Despite labeling requirements and awareness campaigns by Saudi health authorities, food allergies remain a significant challenge in healthcare settings.
Key Statistics
A 2026 systematic review of 20 studies found that food allergies in Saudi Arabia include common allergens like milk and eggs, plus regional triggers such as sesame and seafood that are particularly important in the region.
According to a 2026 systematic review published in Frontiers in Public Health, elimination diets in children with food allergies may increase the risk of nutritional deficiencies, with special concern for vitamin D deficiency in Saudi Arabia where the deficiency is already widespread.
A 2026 analysis of food allergy management in Saudi Arabia found that despite allergen labeling and awareness campaigns by the Saudi Food and Drug Authority, food allergies remain a major clinical problem requiring improved diagnostic approaches.
The Quick Take
- What they studied: How common food allergies are in Saudi Arabia, what foods cause them most often, and how people manage them
- Who participated: The review analyzed 20 scientific studies and official documents from Saudi Arabia and other countries. The studies included various groups of people with food allergies, though exact numbers weren’t always specified
- Key finding: Food allergies in Saudi Arabia follow similar patterns to other countries, but regional foods like sesame and seafood are particularly important triggers. Avoiding these foods can lead to nutritional problems, especially vitamin D deficiency
- What it means for you: If you or your child has a food allergy in Saudi Arabia, work with a healthcare provider to ensure you’re still getting proper nutrition while avoiding allergens. Simply cutting out foods without planning can cause health problems
The Research Details
Researchers conducted a systematic review, which means they searched multiple scientific databases (PubMed, Scopus, and the Saudi Digital Library) for all available studies about food allergies in Saudi Arabia. They followed strict international guidelines called PRISMA 2020 to ensure their review was thorough and unbiased. They found 20 studies and official documents to analyze.
Because the studies they reviewed used different methods to diagnose allergies and measure results, the researchers couldn’t combine all the data statistically. Instead, they organized the findings by topic and study type, creating a narrative summary that shows what we know about food allergies in Saudi Arabia.
This approach is useful when studies are very different from each other, as it allows researchers to see the big picture without forcing incompatible data together.
A systematic review is valuable because it gathers all available evidence in one place rather than relying on single studies that might be incomplete or biased. This helps doctors and public health officials understand the true scope of food allergies in Saudi Arabia and make better decisions about prevention and treatment strategies.
The review followed international best-practice guidelines (PRISMA 2020), which is a strength. However, the findings depend heavily on self-reported data from previous studies—meaning people reported their own allergies rather than being formally tested. This can be less reliable than medical testing. The review also notes that different studies used different methods, which makes it harder to compare results directly.
What the Results Show
The review found that food allergies in Saudi Arabia are similar to those in other countries, with milk and eggs being the most common allergens. However, regional foods unique to Saudi Arabia—particularly sesame and seafood—are also major triggers for allergic reactions.
A critical finding concerns children who eliminate allergenic foods from their diets. Without careful planning, these elimination diets can lead to nutritional deficiencies. This is especially concerning in Saudi Arabia, where vitamin D deficiency is already widespread in the population. Children avoiding multiple foods may not get enough calcium, iron, protein, and other essential nutrients.
The review also examined the effectiveness of current prevention strategies. Despite labeling requirements for allergens and public awareness campaigns by the Saudi Food and Drug Authority (SFDA), food allergies remain a major clinical problem. This suggests that labeling and awareness alone aren’t enough to solve the problem.
The research highlights that lifestyle changes, particularly among younger Saudis, are contributing to rising food allergy rates. The review notes that many reports on food allergies in Saudi Arabia rely on self-reported data rather than medical testing, which means the actual prevalence might be different from what’s reported. The review also emphasizes the need for better diagnostic approaches and standardized methods across different healthcare settings.
This review confirms what international research has shown: milk and eggs are universal allergens across different populations. However, it adds important regional context by identifying sesame and seafood as particularly significant in Saudi Arabia. The finding about nutritional deficiencies from elimination diets aligns with global research showing that restrictive diets require careful nutritional planning.
The review’s main limitation is that it depends on self-reported allergies from previous studies rather than confirmed medical diagnoses. This means some people may have reported food intolerances (which aren’t true allergies) as allergies. The studies reviewed used different diagnostic methods and measured different outcomes, making direct comparisons difficult. The review also doesn’t provide exact numbers for how many Saudis have food allergies because the original studies didn’t always report this clearly. Finally, the review focuses on published research, so it may miss important information from unpublished studies or healthcare records.
The Bottom Line
If you have a food allergy in Saudi Arabia: (1) Get a proper medical diagnosis rather than self-diagnosing, (2) Work with a registered dietitian to plan elimination diets that still provide complete nutrition, (3) Pay special attention to vitamin D intake, as deficiency is common in the region, (4) Check food labels carefully for allergen information. These recommendations have moderate to strong evidence support from the research reviewed.
Parents of children with food allergies should prioritize this information, as nutritional deficiencies during childhood can affect growth and development. Healthcare providers in Saudi Arabia should use this review to improve allergy diagnosis and management. People planning elimination diets need to understand the nutritional risks. Public health officials should consider that current awareness campaigns may need strengthening.
Nutritional deficiencies from elimination diets can develop over weeks to months, so monitoring should begin immediately when starting an elimination diet. Vitamin D deficiency may take longer to develop but should be checked regularly, especially in children. Benefits from proper nutritional planning can be seen within weeks through improved energy and health markers.
