Oxalate in oats is generally low. Levels depend on processing. Oats are a dietary staple worldwide. They're valued for their nutrition and versatility in various dishes. From oatmeal to granola bars, oats are rich in fibre, protein, vitamins, and minerals. They benefit heart health, aid digestion, and support weight management.


Low Oxalate Content in Oats


Oats contain low oxalates, so add them to your diet but watch your portion. Oat flour is also low in oxalate. Oxalate levels differ based on oat type and preparation method.


St Joeseph's Healthcare lists oat bran flakes and oatmeal as been good low oxalate choices. To read more on oxalate lists go to the Resource Library. The information on the table is from the OHF.


Does Preparation Change Oxalate Content?


Yes, the way you prepare oats impacts their oxalate content. Oxalates in foods can lead to kidney stones. Soaking, cooking, and fermenting oats can lower oxalate levels. This might decrease oxalate absorption in the body.


  1. Soaking: Soak oats overnight to lower oxalate content before cooking. It helps by removing oxalates into discarded water. This practice reduces antinutrients in grains and legumes. It includes phytates and oxalates for better digestion.

  2. Cooking: Cooking can also reduce the oxalate content in foods, including oats. The extent of reduction can depend on the cooking method and duration. Boiling food in water lowers oxalate levels. Oxalates can seep into the water, usually thrown away.

  3. Fermenting: Fermentation lowers oxalate in foods, like sourdough oats do. Beneficial bacteria break down oxalates during fermentation. Reduction levels vary with the process and duration.

  4. Rinsing: Rinsing soaked oats before cooking reduces oxalate content by washing away oxalates.

While these methods can lower oxalate in oats and foods, reduction varies. For a low-oxalate diet, consult healthcare or a dietitian. They'll talk to you about limits, preparation, and nutrition balance.
