This evening I made some sweet potato and carrot chips to accompany my Birdseye fish, along with a mini corn on the cob and broccoli. (So good). Meanwhile my other half - 6'3" and permanently slim - had the usual chips and bread with his fish (and none of the extra vegetables in sight). Anyhoo, it occurred to me that I was only having sweet potato as it's part of the new 'eater of vegetables' KT (so far 10 weeks in and I've lost 6kg, which I'm very happy with - another 6 to go) and I had no idea whether they are actually better for you than normal potatoes.
It led me to reading this article which is really long but really fascinating - I was going to share it on Twitter but realised it was probably of a lot more interest to you lot
