Lemon Juice and Kidney Stones
The Consortium has been working with the Mario Negri Institute of Pharmacological Research to support a clinical study on lemons and their benefits in curing kidney stones.
These painful stones are formed by the crystallisation of salts in the urine. Urine contains substances that inhibit kidney stone formation: the best known are citrates, which are also present in lemons.
The study has demonstrated that the citrates in lemon juice, when coupled with the standard diet for the prevention of kidney stones, can help reduce the formation of new stones when compared to the diet alone. A new study is underway to test these observations under clinical conditions.
Dietary instructions for sufferers usually involve an appropriate intake of water per day, a sodium-restricted diet, low in animal protein, but with a normal amount of daily calcium. It is thought that lemon juice provides the amount of citrate needed to prevent the crystallization of urine salts. The Siracusa Lemon (PGI) naturally has higher levels of citric acid and so it is thought more useful than other lemons for this treatment.
