Watermelon juice is the best recommendation, if you are in India. In case you can not get fresh water melon, take 1 tbsp watermelon seeds or cucumber seeds, pound them a little so that the shell breaks, and put them in a vessel containing 400 ml water (1 quart). Boil on simmering fire till water quantity is reduced to half. when this water is luke warm, add 1 lemon juice and 1 tsp honey, and drink. This decoction to be taken three times a day. follow diet recommendation given at above link.
In food, it will be beneficial to take leafy vegetable soups, but keep changing the vegetables, instead of taking only one.
