Why can't somebody clever make all vegetables taste

like the potatoe? My nephew will not eat vegetables such as carrots, cabbage, beans, cauliflour...all the usual suspects, he'll eat potatoes though...he likes the taste. I expect there are lots of children and adults who are missing out on nutrients from vegetables because they dislike the taste so why can't the greater powers that be change the flavour of food that tastes like shit? While I'm on the taste subject, why can't chocolate be made to taste foul, I love chocolate and it loves my hips and thighs...sooo much, is there something I can do besides to use my own will-power to stop me from eating it...I don't have enough strength to deny myself my fix of chocolate everyday but if it didn't taste so fucking nice I wouldn't crave it. Oh shit I don't know, I'd kill for a twix right now.
