Are food colourings safe to eat?

that was a very interesting question at I'm a Scientist

I’ll tell you a story: if you drink squash at the house, have a look at the label, you can read about the flavourings and the artificial sweetenets you have there…
Each of these chemicals is safe to eat on its own but NOBODY has studied if eating two of these chemicals together is safe or toxic…Imagine now how many different chemicals (preservatives, sweeteners, flavourings etc) we eat every day. All these end up in our body…nobody knows if they react together or if they cause any synergistic effect. Synergy is when the end result is greater of the sums.
now look at this picture

two chemicals can have this synergistic toxicity…
conclusion: the less chemicals we eat, the better!
