Sir: Why all this hoo-hah over food fads ('Junk-food diet threatens collective health', 2 March)? We should enjoy our food, fatty or not, but eat everything in moderation. The same with alcohol and sex. Let's eat, drink and be merry, we all have to die at some point. Life is not a rehearsal, let's live it to the full and enjoy ourselves, and say 'Bah, humbug]' to the moaning minnies who try to spoil our lives with their 'Thou shalt nots]'.
