Rapini is an excellent source of vitamins C and K, folate, calcium, potassium and beta-carotene. Just half a cup (125 ml) of cooked rapini has 31 milligrams of vitamin C (35 to 40% of a day's worth!), 60 micrograms of folate (15% of your daily requirement) and 1.8 milligrams of beta-carotene.
Thanks to its sizable vitamin K content, rapini is good for bone health. Scientists speculate it takes about 250 micrograms of vitamin K to help keep bones from thinning. A one half-cup serving of rapini makes a hefty contribution delivering 217 micrograms.
Rapini also supplies lutein, an antioxidant that protects the eye's retina from oxidative damage that can lead to age-related macular degeneration and cataract formation. Rsearch suggests that people who consume the most lutein from foods have a 20 to 50 percent lower risk of cataracts compared to those whose diets contain the least.
Include at at least one serving of leafy green vegetables daily diet.
Here's the nutrient breakdown for one half cup (125 ml) serving of cooked rapini:

Rapini is scientifically classified as Brassica rapa and although it resembles broccoli, it is actually closely related to the turnip.
Other common names for rapini include broccoli raab and broccoli di rape. Most rapini found in Canada comes from California, where it's available year round with the peak season being from late fall to early spring.
You'll find locally grown rapini at farmer's markets July through October.
Choose bunches of rapini with plump, moist stems and dark green leaves. Young rapini has broccoli-like buds that are closed or partially opened. Avoid rapini that has most of its buds open or has wilted, spotted or yellowish leaves.
To keep rapini at its freshest, wrap it in paper towel and store in a perforated plastic bag in the refrigerator vegetable crisper for up to five days.
Wash rapini only before using it. If stored wet, the excess moisture will cause rapini to deteriorate faster.
Rapini can also be frozen after it's blanched in boiling water for 2 minutes. After blanching, drain the rapini, allow it to cool, then put it in a sealed container. It can be stored in the freezer for up to a year.
First, rinse and trim a quarter of an inch from the bottom of the stems and cut the stalks crosswise into 2-inch pieces.
Rapini, like other leafy greens, can be prepared by blanching, braising, sautéing or steaming.
To blanch, rapini, drop into salted (optional) boiling water and remove after two minutes.
To braise, put rapini in a skillet with just enough liquid to cover it. Let the rapini simmer for 10 to 20 minutes on low heat.
To sauté rapini, add the cut vegetable to a lightly oiled hot pan and heat for three minutes while stirring constantly.
To steam rapini, put it in a pot with very little water, cover and heat on low just until the leaves wilt. Or place uncooked rapini in a steamer basket and cook over simmering water until wilted.
All parts of rapini are edible - the stems, the leaves, the buds and even the flowers.
Rapini has an assertive but pleasant bitter taste that mellows with cooking. (If you find the taste of rapini too bitter, blanch it before sauteeing or adding to pastas and stir-fries.)
It pairs well with crushed garlic and chilli flakes but can be used in many different dishes.
