It’s thought that the name is taken from Asian culture, which in the 17th century, was enjoying a pickled fish sauce, known as ke-tsiap, or kecap. The source of our word ketchup may be the Malay word kêchap, possibly taken into Malay from the Cantonese dialect of Chinese. Kêchap, like our word, referred to a kind of sauce, but a sauce without tomatoes; rather, it contained fish brine, herbs, and spices. It was also believed that it could help prevent colds due to the Vitamin C that it contained.Scientific studies claimed that tomatoes had antioxidants which were beneficial in preventing cancers
 The
 first ketchup recipe was printed in Elizabeth Smith’s The Compleat 
Housewife, in 1727, but alas, it was still anemic. There were no red 
fruits of the vine. But in 1812, a recipe for tomato ketchup appeared in
 the Nova Scotia cookbook of a transplanted American, who called it 
“love apple” ketchup.
