Assuming this question refers to an area of space where gravitational forces are negligible and the astronaut is not accelerating, and there is no frame of reference for up or down, then, no because there is no upside down. Two astronauts could be positioned in opposite directions however, and they both could eat.
There is no upside down or right side up or sideways in space. All orientations are equivalent. So this question is meaningless.
As all orientations, even changing ones, are equivalent astronauts can eat equally well in any orientation, even tumbling and doing somersaults.
