What about the oxalic acid in beets? Is it good for you to take in large amounts?

As noted in my video about the oxalates in turmeric versus cinnamon (Oxalates in Cinnamon), it’s not just the amount that matters but also how well particular oxalates are absorbed, and the bioavailability of oxalates in beets is relatively poor (6 times less so than spinach, for example). Cooking the beets could cut levels about 25% but for the rare person with a condition like idiopathic calcium nephrolithiasis (a type of kidney stones) that needs a low-oxalate diet, a better high-nitrate vegetable choice would be arugula.

  • May you please recommend a plant based “alternative” or treatment to dissolve oxalates in joints. May enchondromas be associated with high absorption of oxalates from food when fat absorption issues are present?

    How much oxalic acid is safe to eat? According to wikipedia 600mg/kg is lethal, but how much is “just bad”?


  • do you believe in the need of cutting oxalates for conditions like IBS or leaky gut? Im only making the connection recently, but I always react badly to spinach and Im afraid of getting worse in my conditions after turning vegan/plant based. The other day I threw up after a watercress+lemon+ginger+ cucumber smoothie. I would appreciate your insight, as always. Thanks!
