Understanding the rise of food allergies in the US

Food allergies are rising, with over 10% of US adults affected. This increase is linked to environmental changes and factors like increased C-section births. Experts suggest that vaginal birth, breastfeeding, and a Mediterranean diet during pregnancy may reduce a child's risk of developing food allergies. Some allergies can be outgrown, but common ones like peanuts and shellfish often persist. While the "big nine" allergens account for most reactions, over 170 foods can cause allergies. Differentiating between allergies and intolerances is crucial for safety, as allergies trigger immune responses that can be life-threatening.
