Nut allergies are one of the most common food allergies, affecting millions of people around the world. These allergies occur when the immune system reacts to proteins found in certain nuts, such as peanuts or tree nuts like almonds, walnuts, and cashews. Even a small amount of these proteins can trigger allergic reactions in some individuals. These reactions vary in severity, ranging from mild symptoms like itching or hives to more serious effects, such as difficulty breathing or anaphylaxis.

The prevalence of nut allergies seems to have increased over the years, particularly among children. Research indicates that millions of people worldwide deal with these allergies, with cases often being diagnosed in early childhood. However, nut allergies can also develop later in life. Experts have studied this rise closely, though the exact reasons remain unclear. Changes in dietary habits, genetic factors, and environmental influences are some areas researchers examine.

Nut allergies require attention because they can have significant impacts on daily life. People with these allergies often need to carefully check food labels, avoid certain dishes, and stay prepared for potential allergic reactions.

Even trace amounts of nut proteins in food can pose risks for some individuals. Understanding nut allergies is not only important for those affected but also for others, including friends, family, and caregivers who prepare meals or share spaces with someone who has an allergy.
