Boiling markedly reduced soluble oxalate content by 30-87% and was more effective than steaming (5-53%) and baking (used only for potatoes, no oxalate loss). An assessment of the oxalate content of cooking water used for boiling and steaming revealed an approximately 100% recovery of oxalate losses.
Can oxalates be destroyed by cooking?
Contrary to what some books say, cooking does not destroy oxalic acid. However, blanching your greens for a few minutes and disposing of the water leaches out roughly one third of the oxalic acid. That's one third of total oxalic acid but most of the soluble oxalic acid.
Can you boil oxalates out of potatoes?
The present data suggested that boiling was most effective in reducing soluble oxalate content of vegetables compared to steaming and baking (used only for potatoes). The loss of soluble oxalate was 30-87% for boiling and only 5-19% (not including spinach, green Swiss chard leaves, and carrots) for steaming.
Is sweet potato high in oxalates?
Although sweet potatoes are considered a nutritious food, they are categorized as very high in oxalates and unfit for a person on a low-oxalate diet. Foods that contain less than 2 milligrams of oxalate per serving are considered low, according to the University of Pittsburgh Medical Center.
Does soaking potatoes reduce oxalates?
Additionally, soaking or cooking foods can significantly reduce oxalate levels to maximize nutrient absorption. Kidney stones are another common concern associated with oxalate consumption.
