Oxalate contents of raw, baked, steamed, and boiled potatoes are shown in Table 3. Boiling reduced soluble oxalate content by 34%, whereas the loss with steaming was only 5%. Total and soluble oxalate contents were slightly higher in baked potatoes than in raw potatoes.
Do cooked potatoes have oxalates?
A medium baked potato has 97 milligrams of oxalates per serving. Much of this content is in the potato's skin, which contains high levels of nutrients like fiber, vitamin C, and B vitamins.
Can oxalates be reduced by cooking?
Because oxalates are water soluble, they can be reduced by blanching, boiling, or steaming with the liquid discarded. Fermentation reduces oxalates. Cooking in milk or macerating in whey can also mitigate oxalate exposure. Sprouting can help too.
Which potatoes are lower in oxalates?
The Low Oxalate Cookbook (see Resources) shows that skinless red potatoes are Page 2 considerably lower in oxalates than white or russet potatoes; all potatoes are lower in oxalates when the skin is removed. Legumes: kidney, pinto, and adzuki beans.
Does cooking break down oxalic acid?
Heat can break down oxalic acid which will allow the body to absorb higher amounts of vitamins, calcium, iron and fibre. However, many phytonutrients can get destroyed by the cooking process. In addition, water-soluble vitamins, such as vitamin C and B, can leach out during the cooking process.
