If there were indeed any foods that particularly had an effect on penis health, or for that matter, penis growth, in our capitalistic society, it would be made scarce, illegal to grow/produce, and be prohibitively expensive. A major SCUMBAG corporation would seek to patent it so it could not produce seeds, (if it were grown), or the recipe, (if it was a meal), would become proprietary and kept secret. If it were made illegal (think pot), you couldn't even grow, or produce your own without risk of jail/prison.
If any of this ever happens, you can thank big (scumbag) corporations and their (scumbag) lobbyists.
