Tony Green notes that according to his kettle, the cup he uses for coffee holds two cups, but his coffee maker thinks it is three (Letters, 2 March). You report that the UK's National Health Service recommends servings of 80 grams. A standard US serving of fruit, vegetables, meat and fish is 4 ounces, which is 112 grams. Does this make you all slimmer than us Americans? It makes the difference between a recommendation of five cups per day and one of four per day.
