Supposedly, I have to cut back on Spinach as something in that may contribute to another kidney stone for me (Ouch!) but I can make up the difference in Kale. ;)
Broccoli, Brussel Sprouts, Cabbage, Cauliflower, Kale, Watercress. Bok Choy and Turnips are also mentioned. (Rutabagas not on the list but would as well.)
"When food is chewed or prepared, the enzyme myrosinase turns glucoraphanin (a type of glucosinolate) found in cruciferous vegetables into sulforaphane, per Oregon State University Linus Pauling Institute."
Always good to be able to grow your own supply!
