Il sulforafano contenuto nei germogli di broccolo di 4 giorni ha delle incredibili proprietà su di una moltitudine di processi metabolici proteggendoci da moltissime malattie; da quelle metaboliche, neuro degenerative, cardiovascolari fino al cancro e molto altro. Nel seguente video la Dr.ssa Rhonda Patrick illustra la sua ricerca ed i suoi risultati in merito agli effetti benefici del sulforafano ed alla sua importanza nella dieta.
Il video è abbastanza lungo, dura circa 47 minuti ed è in lingua inglese.
