I don't think you can say that fruit is the healthiest of your choices. It's only one choice among many you can make. If at this point in the transition fruit is a problem it is probably best to stay away from it. I think it's good to start this way of eating with a good palate cleanse. It gets you to the point where a good butternut squash tastes sweeter than a chocolate sundae used to.
