About Urinary Lithuania
Introducing Urinary Lithuania refers to the presence in the urinary tract (kidneys, bladder, ureter) of small stones formed by the abnormal agglomeration of matter. These stones are either naturally present in the body or produced by bacteria. The diet definitely plays a role in the prevention and remission of this disease.
The various types
There are two types, accounting for 70-80% of urinary lithiasis: oxalate and calcium stones.
Oxalate
These stones contain abundant oxalate. Oxalate is a crystal composed of calcium, and is the cause of renal lithiasis. Oxalate occurs in 30-60% of cases. People with this type of urinary calculus need a diet low in oxalate. The foods that contain the most are chocolate, asparagus, watercress, rhubarb, tea, coffee, beet, sorrel and parsley.
Calcium
Calcium-rich stones are the result of excessive calcium intake, probably due to high consumption of dairy products. The recommended daily calcium intake for a healthy adult is 900 mg.
They may also be the result of excessive protein intake, particularly of animal origin. Excess salt can also be a factor in the elimination of calcium from the blood. They may be due to bone calcium loss. This loss needs to be identified and managed, to prevent the development of osteoporosis. In this sense, calcium lithiasis can help prevent the further development of bone pathology. What about protein? According to ANSES recommendations, protein intake should be 0.8 to 1 g/kg/day, with meat limited to 150 grams per day, and salt intake limited. Salt should be limited to cooking, and should not be available at the table. Consumption of processed foods, which are generally high in salt, is not recommended on a daily basis.
