Eat broccoli sprouts for metabolic syndrome

This 2022 rodent study investigated sulforaphane’s effects on insulin resistance:

“Insulin resistance is one of the defining clinical traits of metabolic syndrome, which represents a constellation of metabolic disorders, mainly comprising obesity, type 2 diabetes mellitus, atherogenic dyslipidemia, and hypertension. This study aimed to investigate therapeutic effects and potential mechanisms of sulforaphane (SFN) on high-fat diet (HFD)-induced insulin resistance. Control chow diet was 10 kcal% fat, and HFD was 60 kcal% fat.

  • SFN was found to effectively reduce body weight, fasting blood glucose, and hyperlipidemia, and improve liver function in HFD-fed mice.
  • SFN led to increased expression of antioxidant genes downstream of Nrf2, and decreased accumulation of lipid peroxides MDA and 4-HNE.
  • SFN significantly reduced glutathione peroxidase 4 (GPx4) inactivation-mediated oxidative stress by activating the AMPK and Nrf2 signaling pathways.

Data suggested that GPx4 could be a key target through which SFN might activate Nrf2/ARE signaling pathway to decrease the extent of insulin resistance induced in HFD-fed mice. Taken together, SFN ameliorated HFD-induced insulin resistance by activating the AMPK-Nrf2-GPx4 pathway, providing new insights into SFN as a therapeutic compound for alleviation of insulin resistance.”

This study’s sulforaphane dose was the same as Eat broccoli sprouts for your heart and Broccoli sprouts activate the AMPK pathway at 0.5 mg / kg. It was administered five times a week for 8 weeks to a subgroup of HFD-fed mice starting after 8 weeks of HFD.

A human equivalent oral dose to these three studies’ subcutaneous doses would be a low (0.5 mg x .081) x 70 kg = ~3 mg sulforaphane. Per Eat broccoli sprouts for your gut, my sulforaphane intake is six times that every day.

  1. Thank you for these posts. I am eating at lest 40 grams of broccoli sprouts and at least 20 grams of daikon radish sprouts every morning. Every new report seems to validate this strategy. I always have them before noon as I believe they boost the circadian rhythm and the circadian rhythm for humans maxes out between 1 and 2 PM.

    • Hi David! Thanks for commenting.
      The three rodent studies mentioned in this post all used low sulforaphane doses. That’s very encouraging in showing that just a little bit done consistently will bring about desired changes. They didn’t state time-of-day for their treatments, though.
