I have the same issue, my 9-year old son refuses to eat (and always has) fruits, vegetables and most meats. He is on the high-end of the scale of picky eaters and has even seen medical professionals regarding his diet who all insist that he is healthy and will eat new things when ready. This year, I finally realized that "food wars" were affecting our relationship and was able to convince him to try V8 fusion tropical orange. He takes a "shot" sized glass with every meal (2oz) and drinks carnation breakfast chocolate milk and whatever he is willing to eat out of our meals. These drinks make me feel so much better about the fact that I know he is at least getting some of those nutrients that he otherwise wouldn't get.
