September 1, 2026·23m

Processed food has gotten a pretty terrible reputation.

After all, almost everything we eat has been processed in some way, and everything we eat — including perfectly natural food — is made of chemicals.

Why do manufacturers put preservatives, emulsifiers, artificial flavors, stabilizers and other additives into food in the first place? And does a complicated-looking ingredient label actually tell you much about whether a food is healthy?
