Cucumber: 4 mg (per one medium cucumber)
Low-oxalate vegetables which are also low in calories, include cabbage, chives, cauliflower, cucumbers, endive, kohlrabi, mushrooms, radishes and water chestnuts. Peas, which are legumes, are also low-oxalate.
Foods highest in oxalate
Spinach: cooked or raw, contains over 500 mg of oxalate per serving. Rhubarb: over 500 mg per serving. Rice bran and buckwheat groats: 100 mg to 300 mg per serving. Almonds: 120 mg per serving.
Some examples of foods that are highest in oxalates include green leafy vegetables, soy, almonds, potatoes, tea, rhubarb, cereal grains and beets. Oxalates are also naturally created in the human body as a waste product.
Blueberries and blackberries have only 4 milligrams of oxalates per cup.
Adding calcium-rich foods to meals helps reduce oxalate levels. Calcium naturally binds to oxalate; eating calcium-rich foods at meals helps with this binding and removal of oxalate through the stool rather than through urine.
Some plant foods extremely high in oxalates include, but not limited to: Leafy greens – spinach, Swiss chard, kale, collard greens, celery, parsley, endive, beetroot greens, dandelion greens, and turnip greens. Root crops – beets, carrots, potatoes, sweet potatoes, and parsnips.
Low oxalate protein and dairy include eggs, meat, poultry, fish, yogurt, cheese, milk, and butter. In addition, coffee, water, and fruit juice are considered low oxalate.
Finding low-potassium produce can sometimes be a challenge for people with kidney disease, yet the cucumber offers a tasty treat that is versatile and kidney-friendly.
Porter says fruits and vegetables with high water content, like cucumber, tomato and watermelon, also have natural citrate. "These things are natural stone inhibitors and can be a part of a stone prevention plan to help prevent further kidney stone formation," says Dr. Porter.

BREADS AND GRAINS
White flour and brown rice flour are high in oxalate so everything you make from them will be high.
Food Combining to Reduce Oxalates
Oxalates bind with calcium in the colon, neutralizing their impact on our health. Pair high oxalate foods with calcium-rich foods (i.e. bone broth, canned wild caught salmon and sardines, dairy, shellfish, and crickets). Stay hydrated before eating to dilute oxalates.
The ingestion of the lemon juice seems to dissipate a effect of great quantity of citrates which in turn increases the excretion of oxalates. The presence of these two elements simultaneously: citrate and oxalate compensate for their opposite effect.
Conclusions: The results show that magnesium administration decreases the oxalate absorption, when magnesium is taken together with oxalate. However, magnesium administration does not decrease the oxalate absorption, when magnesium and oxalate intake differ by 12 h.
Milk, hard cheese, yogurt, ice cream, sour cream, cream cheese, cottage cheese, buttermilk, custard and pudding do not contain oxalate.
Peanuts, Spanish peanuts, peanut butter, ginkgo, cashew nuts and pecan nuts all contained relatively low levels of gastric soluble oxalate (147–250 mg gastric soluble oxalate/100 g FW). Almonds, Brazil, pine and candle nuts contained high levels of gastric soluble oxalate (492.0–556.8 mg/100 g FW).
Low Oxalate (1 cup raw strawberries = 4 mg oxalate)
Strawberries, blueberries, blackberries and cherries are all wonderful low oxalate fruits for a healthy kidney stone diet. Raspberries are the one berry exception, coming in at 48mg oxalate per cup. Strawberries make a great addition to yogurt in the morning.
