Eat broccoli sprouts for your kidneys

Starting Year 7 of curating research with a 2021 review of kidney disease and sulforaphane:

“Many chronic kidney disease (CKD) patients progress to end-stage kidney disease – the ultimate in failed prevention. While increased oxidative stress is a major molecular underpinning of CKD progression, no treatment modality specifically targeting oxidative stress has been established clinically.

Pathophysiologic effects occur when there is an imbalance between oxidation and reduction – an altered redox state in which excess free radicals react with other molecules, including lipids, proteins, and nuclear DNA. Mitochondrial DNA is also susceptible to oxidative damage.

All mechanisms discussed above have been shown to be present in CKD. When levels of antioxidant agents such as SOD, CAT, GPx/glutathione, and NRF2 are reduced, harmful effects of oxidation and generation of ROS cannot be appropriately mitigated.

Data suggest continued SFN [sulforaphane] administration is needed to maintain activation of the NRF2 pathway to confer protection against oxidative damage of diabetes. Renal protective effect of SFN has been demonstrated in many other models of kidney injury.

SFN may have therapeutic potential in kidney disease by stimulating the NRF2 pathway.”

Didn’t see where these researchers intended to perform a suggested “clinical study to assess the effect of SFN in CKD.” Keep reading before experimentally treating patients, please. Targets they missed included:

  • Parameters of myrosinase hydrolizing glucoraphanin;
  • “Consumption of broccoli strains with more glucoraphanin leads to higher plasma levels of SFN” and
  • “It follows that SFN could also pose similar adverse effects, particularly if taken in an isolated preparation.”

Also missing from this kidney review were connections to broccoli sprouts’ effectiveness in preventing bladder disease. Not coincidentally, isothiocyanate metabolites accumulate in the bladder.

I came across this paper from it citing Sulforaphane: Its “Coming of Age” as a Clinically Relevant Nutraceutical in the Prevention and Treatment of Chronic Disease. I curated it due to informatively citing Microwave broccoli to increase sulforaphane levels.
