What we know about the health risks of ultra-processed foods

Sure, they're tasty, but packaged snacks and meals can be packed with sugar, salt and a list of unpronounceable ingredients. So what are they doing to your health? Scientists are trying to find out.
Foods classified as ultra-processed are those that have many added ingredients such as artificial coloring, added sugars, emulsifiers and preservatives. An apple may undergo minimal processing when it gets made into applesauce. But when it gets made into a shelf-stable apple pie or candy gummies with added sugars, colorings and flavorings, these foods are considered ultra-processed.

This morning, while tidying up my office, I found an open box of packaged coconut and chocolate cookies that I'd bought sometime last year. The "use by" date had come and gone more than eight months ago. Curious, I took a small bite. They still tasted pretty darn good.

A closer look at the ingredient list revealed some things I've certainly never baked with, including carrageenan and sorbitan tristearate, additives used to do things like thicken, emulsify and preserve the flavor and enhance the texture of food.

Welcome to the world of ultra-processed foods – edible products made from manufactured ingredients that have been extracted from foods, processed, then reassembled to create shelf-stable, tasty and convenient meals.

"These are foods that are industrial creations," says Allison Sylvetsky, an associate professor in the department of exercise and nutrition at the George Washington Milken Institute School of Public Health.

And we're eating a lot of them. Ultra-processed foods currently make up of what the typical adult eats, and of what kids eat.
