This podcast episode is about a mineral called oxalate. O-X-A-L-A-T-E
I know what you are thinking. What is oxalate?
Oxalate is a form of oxalic acid. It is made in plants and in our bodies.
The reason that you probably have never heard of oxalate is that it doesn’t do anything in our bodies. It’s a waste product that our bodies must get rid of after we ingest it or manufacture it.
Although it’s not entirely clear what, oxalates probably do have some function in plants. Some have suggested that oxalate possibly acts as a pesticide.
Even though oxalate does not do anything in our bodies, the reason we need to talk about it is that oxalate is a component of the most common form of kidney stones. Calcium stones–calcium oxalate along with calcium phosphate–form about 80-85% of all kidney stones.
Our bodies need to get rid of the oxalate we eat or manufacture either in the stool or the urine. Too much oxalate excreted in the urine leads to a condition called hyperoxaluria. And kidney stones can be the result.
