A balanced diet

A man went to see his doctor with severe constipation. "What do you normally eat?" the doctor asked him. "Snooker balls," the man replied. "Snooker balls?" the doctor asked in surprise. "Yes, snooker balls," the man replied. "For breakfast, I have the black and the blue. At lunch, I eat the reds and the pink and for supper I have the brown and the yellow." "Ah, I think I know your problem," the doctor said. "You're not eating enough greens."
