I ask this question merely to raise another which is, how much would you tolerate your diet being changed to satisfy medical advice? Would you eat chips without salt on them or drink coffee without sugar if you had become accustomed to enjoying chips with salt and coffee with sugar? Or would you prefer to never eat chips or drink coffee again if the medical advice was you couldn't have salt or sugar? Or would you say "Boll.ox" to that and carry on as normal? How far would you allow someone to go to dictate what you ate?
