Does Drinking Tea Cause Kidney Stones

It’s Not Just The Oxalate

Does matcha green tea cause kidney stones? / Kidney Stone Diet Podcast with Jill Harris

Oxalate is naturally found in many foods, including fruits and vegetables, nuts and seeds, grains, legumes, and even chocolate and tea. Some examples of foods that contain high levels of oxalate include: peanuts, rhubarb, spinach, beets, chocolate and sweet potatoes. Moderating intake of these foods may be beneficial for people who form calcium oxalate stones, the leading type of kidney stones.

A common misconception is that cutting the oxalate-rich foods in your diet alone will reduce the likelihood of forming calcium oxalate kidney stones. While in theory this might be true, this approach isn’t smart from an overall health perspective. Most kidney stones are formed when oxalate binds to calcium while urine is produced by the kidneys.

It is important to eat and drink calcium and oxalate-rich foods together during a meal. In doing so, oxalate and calcium are more likely to bind to one another in the stomach and intestines before the kidneys begin processing, making it less likely that kidney stones will form.

    Caffeine Absorption Metabolism And Elimination

    After oral intake, caffeine is rapidly and completely absorbed from the stomach and small intestine into the blood circulation, and is then distributed to almost all tissues and body fluids. The peak plasma concentration of caffeine is 810 mg/L, which is reached within 15120 min after its intake , whereas its half-life is 5 h . It is metabolized in the liver by cytochrome P450 to become metabolite products, including paraxanthine , theobromide , and theophylline . These dimethylxanthine compounds are then demethylated to monomethylxanthine and finally oxidized to methyl uric acid and other end products . Whereas the majority of the consumed caffeine is metabolized to become various end products as previously mentioned, the remaining amount is intact and directly excreted into the urine without accumulating inside human body .
