The latest medical news for people with allergies and food sensitivities.
A new study found that food allergies are on the rise in adults as well as children. The increase is seen across all ethnic groups. About half of all food-allergic adults reported they developed one or more food allergies after age 18. Shellfish is the most common food allergy in adults, affecting an estimated 3.6 percent of adults in the United States. This is a 44 percent increase in prevalence from the rate recorded in 2004. The study also found that nut allergy in adults (now about 1.8 percent) has risen 260 percent since a 2008 estimate.
