Health benefits of broccoli

  • Broccoli is one of the very low calorie vegetables; provides just 34 calories per 100 g. Nevertheless, it is rich in dietary fiber, minerals, vitamins, and anti-oxidants that have proven health benefits. Total antioxidant strength measured in terms of oxygen radical absorbance capacity (ORAC) of broccoli is 1632 µmol TE/100 g.

  • Fresh Broccoli is a storehouse of many phyto-nutrients such as thiocyanates, indoles, sulforaphane, isothiocyanates and flavonoids like beta-carotene cryptoxanthin, lutein, and zea-xanthin. Studies have shown that these compounds by modifying positive signaling at molecular receptor levels help protect against prostate, colon, urinary bladder, pancreatic, and breast cancers.

  • Fresh vegetable is exceptionally rich source of vitamin-C; providing 89.2 mg or about 150% of RDA per 100 g. Vitamin-C is a powerful natural anti-oxidant and immune modulator, helps fight against flu causing viruses.

  • Further, it contains very good amounts of another anti-oxidant vitamin, vitamin-A. 100 g fresh head provides 623 IU or 21 % of recommended daily levels. Together with other pro-vitamins like beta-carotene, alpha-carotene, and zea-xanthin, vitamin A helps in maintaining the integrity of skin and mucusa. Vitamin A is essential for healthy eye-sight and helps prevent from macular degeneration of the retina in the elderly population.

  • Broccoli leaves (green tops) are an excellent source of carotenoids and vitamin A; (16000 IU of vitamin A per 100 g) carrying these compounds several times greater than that in their flower-heads.

  • Fresh heads are an excellent source of folates; contain about 63 µg/100 g (Provides 16% of RDA). Studies have shown that consumption of fresh vegetables and fruits rich in folates during pre-conception, and pregnancy helps prevent neural tube defects in the offspring.

  • This flower vegetable is a rich source of vitamin-K and B-complex group of vitamins like niacin (vit B-3), pantothenic acid (vit.B-5), pyridoxine (vit.B-6), and riboflavin. Further, its florets also hold some amount of omega-3 fatty acids.

  • Furthermore, it is also a good source of minerals like calcium, manganese, iron, magnesium, selenium, zinc and phosphorus.

Selection and storage

Fresh broccoli heads can be available year around. In the market, choose fresh, bright, compact, firm textured flower heads with rich flavor. Avoid those with overmature florets featuring yellow flower buds, excessive branching and hollow stem ones. Whenever possible, buy organic farm produces to get maximum health benefits.

Once at home, rinse flower head by dipping it upside down in salted water for up to 30 minutes and then wash again in running cold water before use in cooking in order to remove any pesticide residues and dirt. Broccoli greens should also be treated in the same way as you do in washing any other greens like spinach.

Eat broccoli while they are fresh. Otherwise, it can be placed inside the refrigerator wrapped in a zip pouch where it may keep well for few days.

Preparation and serving methods

Fleshy flower heads, stalks and leaves are edible. Broccoli sections are being used in varieties of delicacies. Tough stalks and thick leaves are trimmed using paring knife.

Here are some preparation tips:

  • Young, tender, broccoli heads may be eaten raw or as salad.
  • Its flower heads are much sought-after in stir-fries; either alone or with other vegetables, beans and poultry, in mouth-watering recipes mixed with sauce, oil, onions, pepper, and garlic.

  • Extensive boiling and microwaving of broccoli has been found to destroy heat sensitive vitamins like folate, anti-oxidants like vitamin-C, and some of its anti-cancer phyto-nutrients. However, employing few of other brief preparation methods such as mild-steaming, and gentle braising may not alter much of the composition of these compounds.

Safety profile

Like other members of the cruciferous family, broccoli contains "goitrogens" which may cause swelling of thyroid gland and therefore, should be avoided in individuals with thyroid dysfunction. However, it may be consumed liberally in healthy persons. (Medical disclaimer).
