Which is the best ketchup for my child Heinz or Maggi?

May I ask if it is absolutely important to give ketchup? The reason I am saying this is because ketchup is loaded with preservatives and is not at all good for anyone, let alone children. Personally, I never eat ketchup, and thankfully, my kids have learned by example and don't eat it either. When needed, I make different chutneys at home, such as tomato chutney, coriander chutney, mint chutney and such, and the freshness and taste is way better than what you buy from the store.
