Dear Ruth Livingstone, > How much is 1g vitamin C in terms of natural food? > One orange? Half glass carton orange juice? > Anyone know? more fruit than is good for you I suspect Manual of Nutrition (HMSO ) says Vit C content /100gr is Oranges 50mg Blackcurrants 200mg green pepers 100mg 500gr of blackurrants (=1 gr Vit C) is quite a bit of Ribenna and would do me in I suspect. Abolish the colds but get the runs instead!!! all the best Chris Chris Derrett Barton House Health Centre 233 Albion Road Stoke Newington London N16 9JT Tel+44 171 249 5511 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
