Depending on national regulations, rare food allergens are not regarded as major food allergens. Consequently, there is a notable lack of information devoted to rare allergens, despite the significant health risks they pose to sensitized individuals, including potentially fatal anaphylactic reactions. Rare and Risky Food Allergens: Clinical Relevance, Cross-Reactivity, and Management addresses that gap by providing an authoritative overview of uncommon food allergens such as fruits, legumes, rice, mammalian milk and meat, honey, wheat beer, chocolate, coffee, edible insects, algae, spices, green tea, and selected food additives. Each chapter examines these allergens from multiple perspectives-molecular identification, immunological mechanisms, cross-reactivity with respiratory or contact allergens, diagnostic approaches, and management strategies. Bringing together chapters written by international leaders in clinical care, research, and education, this book offers both an assessment of contemporary knowledge and practical guidelines. It aims to equip researchers, academics, students, health practitioners, and nutritionists with a comprehensive understanding of these less common but clinically important allergies, enhancing their ability to recognize and manage these serious health concerns effectively.
