Sulforaphane is also considered a nootropic which can be traced to its ability to cross the blood-brain barrier. increasing glutathione as an Nrf2 activator; promoting weight loss; slowing aging by activating heat-shock proteins; boosting liver function ; reducing inflammation and pain; stopping and reversing hair loss. Reminders from Eat broccoli sprouts today: It looks like this study compared two types of heating: (1) via microwave; and (2) via a pot containing water and broccoli . The older study methods were difficult to implement in kitchens, and evaluated heating temperature as the only factor. A significant loss of ESP activity paralleled the decrease in sulforaphane nitrile formation. Microwaved at 60°C, the florets had a concentration of GLR and SFR at 2.78 and 2.45 µmol/g DW, respectively, which was significantly higher than the levels detected in mixture of florets and stems (1.21 and 0.82 µmol/g DW, respectively).”. Broccoli sprout benefits are numerous, and in part, come from a potent compound called sulforaphane. 24% CO2 at 20°C, whereas no such increase was observed following storage under normoxia at ca.
