Kidney stone patients usually should avoid eating foods such as spinach, shrimp skins, pork liver, beets, and chili peppers.

1. Spinach: Spinach contains high levels of oxalate, which can easily lead to oxalate deposition in the kidneys after consumption, increasing the size of kidney stones.

2. Shrimp skins: Shrimp skins are rich in calcium. If kidney stone patients consume excessive calcium, it may cause calcium deposition, thereby worsening their condition.

3. Pork liver: Pork liver contains high levels of purines. After purines are metabolized in the body, they produce uric acid, which can cause oxalate to precipitate in urine, thus worsening the condition of kidney stone patients.

4. Beets: Beets also contain high levels of oxalate, and consumption may increase the size of kidney stones. Therefore, kidney stone patients should try to avoid eating beets.

5. Chili peppers: Spicy and irritating foods such as chili peppers can easily increase water consumption in the body, causing urine to become concentrated, thus hindering the recovery of kidney stone patients.

Kidney stone patients should maintain healthy lifestyle habits such as moderate exercise and drinking plenty of water, which can also help prevent and control the formation of stones.
