Broccoli..cauliflower, cabbage, kohlrabi, brussel sprouts…
Broccoli is a plant from the cabbage family, brassicaceae. This group of vegetables has been reported to have a role in cancer prevention. Green vegetables anecdotally have been used in juices and eaten raw to boost immunity. Science is reporting chemical pathways and undertaking clinical trials that may explain the benefits of consuming broccoli and other vegetables from the brassicaceae group.
History
The origin of the word broccoli is from the latin “bracchium” meaning arm. There is refernce to broccoli from Roman times. Broccoli is a cultivated wild cabbage that originated in the mediterranean. Domesticated cabbage has bred into varying forms including cauliflower, cabbage, kale, kohlrabi and brussel sprouts all of which are in the same species. It did not become popualr in the United States till the 1920’s.
Why is broccoli beneficial?
Broccoli is high in vitamin C, soluble fibre and sulfuraphanes .The fibre is described as indigestible fibre and includes cellulose which can be seen when cutting the stalk. This fibre is valuable for the digestive system because it attracts water and aids defecation.
Broccoli also contains nutrients with anticancer properties such as diindolymethane and selenium. Diindolymethane (DIM) derived from the digestion of indole 3 carbinol in broccoli has reported anticancer, antiinflammatory , antiviral ,antibiotic and hormone control effects. Broccoli has a reputation as a medicinal plant and DIM is currently involved in clinical trials. The composition of vitamins and minerals in broccoli is vitamin A, betacarotene, thiamine (B1), riboflavine (B2) niacin (B3), pantothenic acid (B5), vitamin B6, folate, viitamin C, calcium, magnesium, phosphorous, potassium, zinc.
How can broccoli consumption be increased?
Broccoli can be eaten raw in this case the nutrients are fully retained. It is prudent to rinse before consuming. It can be eaten lightly cooked and consumed hot or cold and also cooked in a soup. It is reported that boiling and steaming causes a significantly greater loss of vitmin C than microwave cooking or pressure cooking 2
What gives broccoli its colour?
Broccoli contains chlorophyll. This green pigment transforms energy fromm the sun and carbon dioxide into chemical energy in the form of oxygen and carbohydrate. This process is essential for plant life. Broccoli has a high concentration of chlorophyll.
From this knowledge one can understand that with prolonged cooking as the vegetable changes colour and becomes grey, the nutrients have reduced.
Vitamin C level is higher when the vegetable is eaten in season 3.
What about cabbage, cauliflower, kohlrabi, brussel sprouts?
These vegetables are related in the brassica family and are believed to act similarly.
Nursing mothers have used cold cabbage leaves on their breasts to relieve breast engorgement despite scientific validation of a benefit. Dr Pathka a Polish epidemiologist has reported, but yet unpublished, the increase in breast cancer incidence in Polish female migrants to USA may be associated with a decreased cabbage consumption from 3-4 servings in Poland to one per week in the USA.
