A few tips about broccoli:
- when buying broccoli, select florets that are dark green, even bluish or purplish green, because they contain a higher concentration of beta-carotene then pale green or yellowish-green florets. Select broccoli that is firm and not limp.
- consume both the stems and the leaves as they are good sources of nutrients as well -- the stems are high in fiber and the leaves are high in beta-carotene.
- when cooking broccoli it is best to peel off the tough outer layer of the stem before cooking (use a potato peeler). Slice them into medium size pieces and cook for 2-3 minutes before adding the florets; add the leaves along with the florets.
