In rich countries, most salt in our food comes from packaged snacks and restaurant meals, but in poorer countries, people usually add salt themselves while cooking or use salty sauces like soy sauce.

In the U.S., five common foods—pizza, bread, deli meats, soup, and tacos/burritos—add up to more than one-fifth of all the salt people eat, and each one alone adds about 4-5% of that salt. That’s why health experts think cutting salt in these foods could help everyone eat less sodium.
