The intake of fruits and vegetables can dilute the risk factors of stone formation in urine. Therefore, increasing the intake of fruits and vegetables can prevent the recurrence of stones. Eat more foods rich in vitamins, such as fresh vegetables, cucumbers, black fungus, red dates, bananas, watermelons, persimmons and other foods rich in vitamin B, as well as foods rich in vitamin C, such as kiwis and oranges.

2. Increase the intake of coarse grains and cellulose.

Cellulose in food can reduce the formation of urinary calcium, such as wheat bran bread and rice bran in wheat bran food, which is effective for recurrent high calcium urinary calculi. Rice bran can reduce the excretion of urinary calcium and reduce the occurrence of urinary calculi, but it is necessary to avoid a large number of cellulose foods rich in oxalic acid such as wheat bran.

Eat more black fungus.

Because the alkaloids contained in auricularia auricula can promote the secretion of various glands in digestive tract and urinary tract, and assist these secretory substances to catalyze stones, lubricate pipes and discharge stones. Auricularia auricula also contains a variety of minerals, which can also produce a strong chemical reaction to various stones, making them peel off, differentiate and erode, making small stones fall off and shrink continuously, and finally excrete with urine.

Eat more foods containing vitamin B: Scientists have found that vitamin B6 can reduce the content of oxalate in blood, thus preventing the formation of stones. Magnesium also seems to prevent stones. Doctors can advocate taking vitamin B6 or magnesium (or a mixture of both) every day. When supplementing vitamin B6, do not exceed 25 mg per day.

Eat more foods containing vitamin A: Vitamin A is necessary to maintain the overall health of the urinary tract. Foods rich in vitamin A include sweet potatoes, pumpkins, bamboo shoots, broccoli and carrots. Don't take vitamin A supplements in a hurry. If you take too much vitamin A, your body can't excrete it, and it will accumulate and produce toxicity.
