An estimated one out of every 10 people in the U.S. has some kind of food allergy, which adds up to more than 33 million Americans.

Peanut allergies are among the most common and certainly take the lead as the most visible.

But peanut allergies weren't always so prevalent.

In the late 1990s, a nationwide survey found that peanut allergies were reported in 0.4% of American children. Just over a decade

for Scientific American.

Marin is a journalist who covers food policy and public health.
