1. Be aware of and moderate the amount of oxalate rich foods you eat if you are sensitive to oxalates.

2. Eat More Avocado- They help you absorb more from the plant foods you eat and promotes good gut bacteria that can help reduce oxalate absorption.

3. Eat Good Belly, Kefir, and other probiotics that promote Lactobacillales. 

4. Eat more squash, broccoli, & raisins, they are naturally have low oxalate levels.  Here is a link to a great broccoli raisin salad with cashews-
