Myth 3 A high-protein diet puts stress on your kidneys

Your kidneys are incredibly efficient at filtering unneeded substances from your body. And as far as we currently know, consuming a high-protein diet doesn’t increase the strain on your kidneys. The kidneys are built to handle exactly this sort of stress!

To give you an example, one-fifth of the blood pumped by your heart gets filtered by your kidneys every minute or two. Adding a little extra protein may cause a slight increase in the workload, but it’s really just a drop in the bucket compared to the total amount of work your kidneys already do.

That said, I do recommend increasing your water intake when you’re consuming a higher quantity of protein, because your body produces more urine as a means to eliminate the byproducts of protein breakdown. Extra fluid is needed to replace what is lost via urine. But you should be drinking plenty of fluids anyway!

I’ll tell you what does put a lot of unnecessary stress on your kidneys: alcohol. If you’re looking to give your organs a break, start there!
