Food Allergies Statistics – Food allergies are an increasing global health crisis with serious implications for public health. Over recent years, their prevalence has steadily risen affecting millions of individuals; although the exact causes remain under investigation.
As awareness, research, and support for those living with food allergies increase exponentially so does awareness for them as an issue requiring further investigation and support – food safety measures, and label transparency education programs must be prioritized to decrease the impact of this widespread issue and enhance quality of life for those affected by them.
Food allergies are relatively common. In the United States, for example, it is estimated that about 32 million people have food allergies, which is roughly 10% of the population. This prevalence can vary by country and region.
The most common food allergens are often referred to as the “big eight.” These include milk, eggs, peanuts, tree nuts, soy, wheat, fish, and shellfish. However, other foods can also cause allergies, so it’s important to be aware of potential allergens in the foods you consume.
Food allergy prevalence appears to be on the rise, but the reasons for this increase are not entirely clear. Some studies suggest that genetics, environmental factors, and changes in diet may play a role. However, more research is needed to fully understand this trend.
Food allergies can range from mild to severe. While some people may experience only mild symptoms, such as hives or an itchy throat, others may have life-threatening reactions known as anaphylaxis, which can lead to difficulty breathing and a drop in blood pressure. Anaphylaxis requires immediate medical attention.
Some children do outgrow their food allergies, particularly those to milk, eggs, and soy. However, allergies to peanuts, tree nuts, and seafood are often more persistent and tend to last into adulthood. Regular evaluation by an allergist is essential to monitor changes in food allergies.
Food allergies are typically diagnosed through a combination of medical history, skin tests, blood tests, and oral food challenges. Elimination diets can also be used to identify specific food triggers.
