I would think that in general sprouts or seeds of plants have a more concentrated form of whatever nutrients are in the plant itself.
Can you get broccoli seeds or sprouts to plant at home like you can plant other sprouts? That might be a fun experiment and a good way to get a fair amount of them anytime you want. I eat broccoli and/or other vegetables (various cabbages, cauliflour, brussel sprouts, kale etc.) in the same category everyday.
