We’re solely fascinated by 1 right here – dietary.
Then we will break it down additional, as a result of there are 6 fundamental facets of the eating regimen that may have an effect on kidney stone formation:
Once we take into consideration protein powder, most of these don’t apply. Hydration, calcium, sodium, and excessive weight-reduction plan are all separate facets.
How Does Protein Consumption Have an effect on Kidney Stone Formation?
What we do know is that prime protein diets improve the chance of kidney stones.
Many related research have been executed, that present related outcomes. Topics (often inactive) usually improve their protein consumption about 100% (e.g. from 90 to 180 grams per day) whereas lowering carbohydrate consumption. It doesn’t essentially apply to athletes, however it’s a concern.
The query is why does a excessive protein eating regimen trigger an elevated danger of kidney stones?
The analysis factors in the direction of acid-base load (3).
Normally, animal proteins are composed of amino acids which can be later damaged down into acids, whereas plant proteins are damaged down into bases (the other of acidic).
We all know that uric acid kidney stones want a excessive uric acid focus, together with acidic urine with the intention to type (4).

If you happen to’re consuming an inexpensive quantity of protein both manner, you received’t have an elevated danger of kidney stone formation.
How Does Oxalate Consumption Have an effect on Kidney Stones?
Oxalate is present in numerous completely different meals.
It’s additionally present in calcium-oxalate kidney stones. If there may be an excessive amount of oxalate in a kidney, together with different circumstances (like low quantities of liquid), it will probably type stones with calcium.
Oxalate may intrude with the absorption of calcium (6).
That is the massive motive that persons are typically skeptical of vegan protein powders.
Why? As a result of sure plant meals are actually excessive in oxalate. Spinach, beets, and candy potatoes to call a number of.

Realistically, it’s a lot decrease, since pea protein has even much less oxalate in it, and is the primary part in virtually all vegan protein powders.
Based mostly on that, I really feel it’s cheap to conclude that in case your oxalate consumption is inflicting you well being issues (which is admittedly may), it’s not from the quantity in a protein shake or two a day. If you happen to’d wish to see the oxalate content material of extra meals, listed below are 2 good guides:
