Ketchup

Ketchup, per serving size, is healthy.

It’s extremely low in calories and fat while providing both vitamins A and C.

The problem with ketchup is that the great flavoring it provides comes from salt and sugar.

With one serving clocking in at only 1 tablespoon, you can easily add way too much salt and sugar to whatever you might be eating (on top of a lean turkey burger, perhaps).
