You have to be careful when it comes to saying for example, kiwi fruit increased bone mass. If we take this one example, the studies done suggest that lower than recommended vitamin K intake = lower bone mass density in women but not men. So increasing vitamin K consumption by eating kiwi fruit will only have a proven effect if you aren't getting enough already and are a woman. A large study was done to test the effect of delaying the onset of osteoporosis by increased intake of vitamin K. It was unsuccessful in that regard, though did seem to reduce cancer rates http://www.ncbi.nlm.nih.gov/pmc/articles...po=2.00000.
A lot of this is down to very poor reporting of science by people in the media. It is actually fairly difficult to get to what the scientific data actually shows, and for someone without a background in science probably even harder to make sense of it all.
Fruit and Veg can be eaten to assure a good balanced diet and that you get enough of each vitamin etc.
Ben Goldacre's Bad Science book is pretty good when it comes to this sort of stuff.
