Interesting - a potential way to minimize the possible cognitive problems by giving your children broccoli sprouts (or supplements with this compound in them). More research would be helpful in validating this research.
Conclusion:
These findings suggest that Sulforaphane (SFN), an isothiocyanate derived from broccoli and may have prophylactic and therapeutic effects on cognitive impairment in schizophrenia. Therefore, the dietary intake of SFN-rich broccoli sprouts during the juvenile and adolescence may prevent the onset of psychosis at adulthood.
I’m so worried about my kids getting my illness, that I’ve started giving my son greens, a supplement of broccoli and spinach. He won’t eat it regularly, so I give him a vitamin for it. I think it is helping a great deal.
and using Google shopping engine - I’d recommend something from a higher end / quality and reputable supplier (not the cheapest as it may not be what you want)
