Several calcium oxalate–containing plants are toxic, but the degree of toxicity varies depending on the type and amount of oxalate crystals present.

Is calcium oxalate normal in urine?

Calcium oxalate crystals are shaped like dumbbells or envelopes. They’re colorless and can be found in healthy urine. Calcium oxalate crystals are heavily associated with kidney stones, which can form when too much oxalate (found in such foods as spinach) is in the system.

Is oxalate bad for kidneys?

Oxalate is an end product of metabolism excreted via the kidney. Excess urinary oxalate, whether from primary or enteric hyperoxaluria, can lead to oxalate deposition in the kidney. Oxalate crystals are associated with renal inflammation, fibrosis and progressive renal failure.

What is the normal range of calcium oxalate in urine?

The normal level of urine oxalate excretion is less than 45 milligrams per day (mg/day). A higher level of urine oxalate may mean you are at risk of developing kidney stones. Risk of stone formation seems to increase even at levels above 25 mg/day, which is considered a normal level.

What foods are low in calcium oxalate?

A low-oxalate diet doesn’t guarantee that more stones won’t form, but it lessens the chances. Foods that are low in oxalate are bananas, white bread, cabbage, mushrooms, spaghetti, rice, oatmeal, cauliflower, melons and onions.

What causes too much calcium in urine?

Numerous conditions can cause hypercalciuria, or too much calcium in the urine. According to the MedlinePlus, calcium helps a person’s body build strong bones and teeth. Calcium also is important for heart function, muscle contractions, nerve signaling and blood clotting.

Oxalates can bind to minerals and prevent them from being absorbed in the body. The high oxalate content in spinach, for example, can inhibit calcium absorption . But studies have found that if you eat the recommended daily amount of calcium, this effect isn’t seen.

Should I Stop my calcium if I have kidney stones?

Many kidney stone formers, especially women with kidney stones, question whether to stop or reduce their calcium intake. Despite the fact that calcium is a major component of 75% of stones, excessive calcium intake is very rarely the cause of stone formation. In fact, several studies have shown that restricting calcium intake in most stone formers actually increases the number of stones they develop.
