Which of the following is an example of a high-sodium condiment?

Ketchup is considered a high-sodium condiment primarily due to its ingredient composition and the necessity of salt for flavor enhancement and preservation. Commercial ketchup varieties often contain added sodium to improve taste and extend shelf-life, resulting in sodium levels that can significantly contribute to daily intake.

In contrast, olive oil, mustard, and vinegar typically contain much lower amounts of sodium. While some mustard varieties may have a moderate sodium content, they are generally not classified as high-sodium condiments when compared to ketchup. Olive oil and vinegar are primarily fat and acid, respectively, without significant sodium content, making them healthier alternatives for enhancing food flavor without a high sodium load.
