Meat, chicken and fish are not sources of oxalate. Milk, hard cheese, yogurt, ice cream, sour cream, cream cheese, cottage cheese, buttermilk, custard and pudding do not contain oxalate.
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.
Many fruits are considered low-oxalate, meaning they contain less than 2 milligrams per serving. These include bananas, cherries, grapefruit, grapes, mangoes, melons, green and yellow plums and nectarines. Canned fruits including peaches and pears and dried fruits such as raisins are also low in oxalate.
Drink enough water to help your body flush out excess oxalates. Get the recommended amount of calcium, which binds to oxalates during digestion. Limit sodium and sugar intake, which may contribute to kidney stones at high levels.
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.
People who must follow a low oxalate diet may want to avoid eating blueberries. The oxalates in blueberries seem to block the absorption of calcium to some extent. Even though it is not dangerous to eat the two foods together, you might not want to count all of the calcium consumed along with blueberries.
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.
All of the lists I looked at list avocados as low in oxalate so it looks like they are good to go. But in addition to a low oxalate diet, those suffering from kidney stones need to remember to drink plenty of fluids since dehydration can also lead to more kidney stones.
The main sources of oxalate in diets were regular tea and coffee (80-85%). Only 15-20% of oxalate was derived from other plant foods.
Calcium is a nutrient that is found in dairy products, such as yogurt, milk and cheese. You need to eat calcium so that it can bind with oxalate in the stomach and intestines before it moves to the kidneys. Eating foods with calcium is a good way for oxalates to leave the body and not form stones.
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.
All varieties of apples are low oxalate. By themselves, apples are the perfectly portioned portable snack!
White or wild rice. White bread, cornbread, bagels, and white English muffins (medium oxalate) Saltine or soda crackers and vanilla wafers (medium oxalate) Brown rice, spaghetti, and other noodles and pastas (medium 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).
As chocolate is considered as a high oxalate food (Williams and Wilson, 1990, Massey et al., 1993, Noonan and Savage, 1999, Mendonça et al., 2003), The Oxalosis & Hyperoxaluria Foundation (OHF, 2004) recommends that affected persons should avoid eating chocolate.
Some foods that are relatively high in oxalate include broccoli, spinach, kale, okra, parsley, celery, Brussels sprouts, okra, dark leafy greens, and a not-so-green vegetable which leaves many surprised: carrots.
This study confirms that the oxalate contents of ready to eat green and gold kiwifruit are low and unlikely to significantly increase the daily intake of oxalates in the diet.
Dried Fruit
As shown above, dried figs, pineapple, and prunes contain relatively high amounts of oxalate.
Oatmeal is a wonderful whole grain that is also low in oxalate.
1 tablespoon olive oil = very low oxalates.
Oxalate nephropathy is commonly caused by ethylene glycol, vitamin C, and foods like star fruit that contain a lot of oxalate. Peanuts also have high oxalate contents.
