I've said before that I'm not going down the supplements route as I'm not wholly convinced by the science yet. But I'm happy to include turmeric and curcumin in my diet where appropriate - I love Indian cooking so there's plenty of scope.
But when I came to make DS's birthday jelly, on a sea theme to go with his pirate ship cake, I happened to glance at the ingredients list on the back of the packet of jelly sharks/turtles/starfish that we're going in it. One of the colourings used by The Natural Sweet Company is curcumin. Result! As Molesworth would say, "Bash on the wine gums!".
