It is shown that for each convex bodyA?Rnthere exists a naturally defined family GA?C(Sn?1) such that for everyg?GA, and every convex functionf:R?Rthe mappingy??Sn?1f(g(x)??y, x?)d?(x) has a minimizer which belongs toA. As an application, approximation of convex bodies by balls with respect toLpmetrics is discussed.
