There's a plum in my salad!

Scientists have developed a genetically modified tomato which tests on mice suggest can provide a significant degree of protection from cancer. How long it will be before it is available to the general public - indeed whether it ever will be available - will not only depend upon further testing, but also on whether it can get approval from what is a very rigorous EU inspection procedure. And there's a further problem - the genetic modification means that the tomato is purple. Will this make any difference? There seems to be some evidence that purple is an acceptable colour for fruit, but is not a popular colour for vegetables (purple carrots have not been a great success). And most people would classify a tomato as a vegetable, even though it is actually a fruit. So we'll have to wait and see!
