Oxalates are chemicals that are found in plant foods. A low oxalate diet is commonly used to help clear kidney stones or to prevent their formation.
- Restriction of dietary calcium enhances oxalate absorption and excretion, whereas an increase in calcium intake may reduce urinary oxalate excretion by binding more oxalate in the gut.
- The following foods are the most strongly associated with an increase in urinary oxalate excretion:
Foods that have some level of oxalate include:
- Grains such as white corn grits, wheat germ, whole-wheat flour.
- Fruits such as berries (blackberries, gooseberries, black raspberries), concord grapes, red currants, damson plums, peels from lemons, limes and oranges and tangerines.
- Desserts such as fruitcake or other desserts that contain the fruits listed above.
- Protein such as baked beans with tomato sauce, peanut butter and tofu.
- Vegetables such sweet potatoes, vegetable soups that contain very few vegetables, beans (wax, legume and soy), celery, dark leafy greens (swiss chard, endive, escarole, parsley), eggplant, leeks and summer squash.
- Beverages such as draft beer.
