What will boiling the Cambridge Diet soups do?
Boiling water destroys vitamin C, nutrition will therefore not be 100%. Hot, not boiling, water should be added to the powder and mixed thoroughly. Do not mix and then bring to the boil as this will also destroy vitamin C. Loss of vitamin C will also occur if the diet is left to stand any length of time, we therefore recommend that the Diet be consumed within 15 minutes of mixing.
