Any insight into whether matcha drinking causes a higher risk of kidney stones? (Drinking matcha is consumption of powdered tea leaves, unlike nearly all other teas where the goal is to steep and then remove the leaves.)
Your oxalate reasoning suggests matcha would be worthy of study with respect to kidney stones but I've never that. I'm genuinely curious because research suggests consuming leaf solids can be very health-supporting in other ways. e.g. including kidney support to slow progression of diabetes, reducing blood lipid & glucose levels, etc.
