There have been so many television cooks who threw caution to the wind as far as healthy eating went. Then something happened to them in their personal lives and they switched from yelling at people that they were wasting their life not eating tasty dishes to telling people that they need to eat healthy.
Graham Kerr is one of these guys. But should we blame them? Cooking shows are very much like people. They go through their brash phase and eventually wind up getting old and wise. Should be interesting to see what some of today's blowhards will evolve to.
