Ketchup is a tomato condiment sauce which is very popular in many countries. It is generally used to accompany foods such as fries, burgers, hot dogs and other fast-food style dishes. Ketchup is often considered to be not very nutritious, as it often contains a high quantity of sugar and sodium. However, it can be a source of vitamins and minerals, in particular vitamin C and lycopene, if it is made from organic and superior quality tomatoes.
