Problems with that:
1. Fruit are not uniform in size, and do not scale as well.
2. Overall size affects proportion. "Orange-sized" breasts look significantly smaller on a woman who is six feet tall than they do on a woman who is five feet tall.

In both cases, going by heads as a measurement solves the problem.
