Fæst í apótekum, heilsubúðum, Fjarðarkaup, Hagkaup og Melabúðinni brokkoli.is Af hverju brokkolí? Líkaminn verður stöðugt fyrir árásum sindurefna sem skaða frumur okkar. Þessar sködduðu frumur skipta sér líkt og heilbrigðar frumur og er það ferli talin meginorsök fyrir ótímabærri öldrun, hrukkumyndun og gæti leitt til fjölda sjúkdóma. Árið 1992 uppgötvuðu vísindamenn ensímið sulforaphane í brokkolí sem örvar líffræðilega ferlið í frumum líkamans, veitir þeim vernd gegn skaðlegum áhrifum og stuðlar að endurnýjun þeirra. Ferlið sem sulforaphane úr brokkolí hrindir af stað er þekkt undir vísindaheitinu Nrf2. Heilbrigðar frumur – heilbrigður líkami Líkaminn er gerður úr milljörðum fruma og segja má að heilbrigði og vellíðan okkar velti á heilbrigði frumanna. Innbyggt varnarkerfi líkamans verndar frumurnar fyrir skaðlegum áhrifum og stuðlar að endurnýjun þeirra. Þegar á þrítugsaldurinn er komið getur oft reynst erfiðara að virkja þetta innbyggða kerfi og því stundum þörf á hjálp „til að kveikja á því“ – þar getur sulforaphane úr brokkolí spilað stórt hlutverk. Margfalt áhrifaríkara en nokkur andoxunarefni í fæðunni Þegar sulforaphane kemst í snertingu við frumur líkamans berast boð til gena um að auka framleiðslu eigin andoxunarefna í líkamanum – það er margfalt áhrifaríkara en nokkur andoxunarefni í fæðunni! Í þessu sama ferli myndast einnig detoxensím sem hjálpa líkamanum að losa út eiturefni. Jafnframt styrkist geta líkamans til eigin framleiðslu á bólgueyðandi efnum auk taugaboðefna sem efla samskipti fruma. Þetta líffræðilega ferli er lykillinn að heilbrigðum frumum ! Ensímið sulforaphane í brokkolí kann að vera einn öflugasti hvatinn á varnarkerfi líkamans sem verndar og styrkir frumur okkar og vinnur þannig gegn ótímabærri öldrun, hrukkumyndun og ýmsum sjúkdómum.

Brokkolí áhrifin í fjölmi ðlum um allan heim Broccoli treatment for ulcer bug A chemical foun d in broccoli ma y provide the ba sis for a treatment for m any cases of sto mach ulcers and cancer. Laboratory tests found that the ch emical, sulforaph ane can kill off t he bacterium Helicobacter pylo ri. This bug is w idely thought to be responsible fo r the majority of cases of stom ach ulcers and ca ncer. http://news.bbc.c o.uk/2/hi/health /2010386.stm Broccoli may help cut prostate cance r Broccoli may mak e aggressive prosta te cancer less likely . Men who of- ten eat broccoli ma y be less likely to d evelop aggressive p rostate cancer than men who ski mp on those vege tables. The finding comes from a study of more than 29,000U.S. men ag ed 55 to 74whowe re followed for an a verage of four years. The men wh o reported frequen tly eating crucifero us vegetables were 40 percent less likely to be diagnos ed with aggressive prostate cancer. http://www.cbsn ews.com/stories/ 2007/07/24/heal th/webmd/main3 094509.shtml Broccoli kicks canc er Vegetables pack a roundhouse punch against cancer, acc ording to a report by nutritional scientist Keith Sin gletary of the Uni versity of Illinois. He added sulforap hane, a chemical found in broccoli, to cultures of hum an breast cancer c ells. Within hours, the cells stop- ped dividing. Sulfo raphane seems to work by interrupti ng the tiny microt ubules that nor- mally pull pairs of chromosomes apa rt when cells divid e. Without the tub ules, malignant cells can’t multiply . And sulforaphan e seems to leave n ormal cells untouched. http://discoverm agazine.com/2005 /jan/broccoli-kic ks-cancer Broccoli sprouts sh ow potential agains t stomach cancer A daily portion of broccoli sprouts m ay help suppress a common type of bacterial infection that has been linke d to stomach cancer , a new study sugge sts. Broccoli sprou ts contain high levels of an anti-oxidant called sulphorapha ne. In fact, the con centration of sulphoraphane in broccoli sprouts is far higher than fou nd in the full-grow n plant. http://www.gua rdian.co.uk/lifea ndstyle/besttrea tments/2009/ap r/06/broccoli- sprouts-show-pot ential-against-stom ach-cancer Broccoli compound may ameliorate skin disease The natural comp ound sulforaphan e, which is abund ant in broccoli, may ha ve a role in the trea tment of epiderm o- lysis bullosa simp lex, according to a new study. Epid er- molysis bullosa sim plex is a genetic co ndition that cause s the skin to beco me fragile and blister easily from minor injuries or f riction. http://www.reute rs.com/article/idU SCOL5624882007 1205 Broccoli extract co uld help head off s kin cancer New research sug gests that broccoli can prevent the damage from ultra violet light that oft en leads to skin cancer. A smear o f broccoli-sprout extract blocked the potentially can cer-causing damag e usually inflicted by sunlight and sh owed potential advantages over su nscreens. UV-indu ced redness and sw elling was reduced on average by 37 percent. http://www.wa shingtonpost.c om/wp-dyn/co ntent/article/2 007/10/22/ AR200710220137 7.html Broccoli may undo diabetes damage Eatingbroccoli cou ld reverse thedama gecausedbydiabet es toheart blood vessels, rese arch suggests. The key is a compound found in broccoli, called sulf oraphane. It encou rages production o f enzymes which p rotect the blood vessels, and a reduc tion in high levels o f molecules which cause significant ce ll damage. http://news.bbc.c o.uk/2/hi/754163 9.stm Potent chemical to fight cancer seen in broccoli Broccoli harbor s what could be the most powerful anti-can cer compound e ver detected, scientists say. Re searchers have is olated an ingredi ent in broccoli t hat kindles the activity of critica l enzymes in the cell known to he lp gird against tu mors. Many na- tural and synthet ic compounds ha ve been identified that stimulate the se protective enzymes, but the newly discovered chemical in brocc oli is by far the m ost powerful inciter. The chem ical, sulforaphane , could be the ma in reason that pe ople who eat abundant amoun ts of broccoli hav e a significantly r educed risk of ca ncer compared with those who a void the foods. http://www.nytim es.com/1992/03/ 15/us/potent-ch emical-to-fight-ca ncer-seen-in- broccoli.html?pag ewanted=1 Broccoli Compoun d May Help COPD Patients People with ch ronic obstructiv e pulmonary disease (COPD) could benefit fro m an antiox- idant compound in broccoli, resea rchers report. COPD is the fo urth-leading caus e of death in th e United States, affecting more than 16 million p eople, and is ofte n the result of lo ng-term smoking . ”In COPD, there is critical lo ss of antioxidant systems, which p rotect against ox idative stress and inflammatio n,” explained lea d researcher Shy am Biswal. ”Eve n though there is a loss of this system, you can substantially rest ore it with an ac tivator for this pathway,” Biswal said. A compoun d in broccoli calle d sulforaphane h as been shown effective in resto ring antioxidant g ene activity. http://www.wa shingtonpost.c om/wp-dyn/co ntent/article/2 008/09/12/ AR200809120199 7.html Broccoli may reduc e smokers’ lung ca ncer risk If you’re a smok er, eating your ve getables may redu ce your risk of d eveloping lung cancer, a new stu dy suggests. Ame rican researchers have found that eating crucife- rous vegetables le d to between a 20 per cent and 55 p er cent reduction in lung cancer risk, depending o n the type of vege table and how lon g the subject had been a smoker. The research also showed that only the consumption of raw, as op- posed to cooked, cruciferous veget ables reduced lun g cancer risk in current smokers. http://www.ctv.ca /servlet/ArticleN ews/story/CTVN ews/20081118/b roccoli_lungca ncer_081118/200 81118?hub=Healt h Protective protein m ay hold key to neur ological diseases Neurological di seases such as Huntington’s d isease, Parkinson’s, Lou Gehrig’s disease (ALS) and Alzhe imer’s di- sease operate in s imilar ways and in particular are ass ociated with common ev ents within a cel l that lead to cel l death. Nrf2 is a protein that, when you put it into cells, it bring s up all the defen se mechanisms s imultaneously. Not only do you increase the cell’s endogenous antio xidants, but you’r e also increa- sing the enzymes that remove toxic ities from the cel l. The protein als o has a global effect — it doesn ’t just protect tha t which is inside, but also the norm al cells in and around its enviro nment. http://www.news .wisc.edu/10564 Food combining ’fi ghts cancer’. Eating certain foo ds together, such as chicken and bro c- coli or salmon and watercress could h elp to fight cancer , say researchers. C ombining two foo d components cal led sulforaphane and selenium make th em up to 13 times more powerful in attacking can- cer together than they are alone, the y suggested. The discovery could m ean it could be possible to design special cancer-figh ting foods or diet s. http://news.bbc.c o.uk/2/hi/health /2903739.stm Substance in sprou ts cuts inflammatio n linked to asthma A compound fou nd in broccoli m ay help prevent r espiratory inflam mation linked to diseases such as asthma, allerg ic rhinitis and c hronic obstructi ve pulmonary disease, accordin g to a University of California, Lo s Angeles, study. The compound sulforaphane stim ulates increased p roduction of ant ioxidant enzymes in the airway that protect agai nst the large am ounts of tissue- damaging free r adicals humans breathe in eve- ry day in pollute d air, pollen, die sel exhaust and tobacco smoke. This tissue dam age can lead to inflammation. http://abcnews.g o.com/Health/H ealthday/story?id= 7017684&page=1 Broccoli beats oth er veggies in healt h benefits When the Americ an Journal of Clin ical Nutrition pub lished a pa- per that listed fo ods most likely t o prevent colon cancer, what stood out? Brocc oli. Scientists at the Harvard Scho ol of Public Health in Boston published an art icle in the same journal last October and not ed that broccoli, along with spina ch, helped to mi nimize risk for cataracts. When a nother team of H arvard scientists l ooked at how die t might protect against stroke, br occoli’s benefits a gain came to the fore, in research p ublished in the October 6, 1999 issue of the Journ al of the America n Medical Associ ation. When it comes to basic nu trients, broccoli is a mother lode. O unce for ounce, b oiled broccoli has more vitamin C than an orange and as much calci um as a glass of m ilk, according to the USDA’s nu trient database. O ne medium spear has three times m ore fiber than a slice of wheat b ran bread. Brocco li is also one of t he richest sources of vitamin A in the produce se ction. http://archives.c nn.com/2000/FO OD/news/04/13 /broccoli.benefit s.wmd/index. html Molecular Evidence that Broccoli Fights Prostate Cancer Scientists Maria Traka and Richar d Mithen, of the Institute of Foo d Research in N orwich, England, explained that me n who have a ge ne called GSTM1 react well to cruci ferous vegetables. Instead of picking through the medi cal records of people who eat b roccoli, some oth ers that don’t, and then crunching so me numbers, the researchers pe rformed sophistic ated genetic tests upon a group of volunteers — some of whom w ere on a very high broccoli diet. ”To our knowledge, th is is the first dietary interventio n study to analyze global gene expre ssion profiles with in a target tis- sue before and aft er a 12 month inte rvention, and to s tratify gene expres sion profiles by genotype,” said T raka and her co-au thors in the discu ssion section of t heir paper. http://www.wired .com/wiredscienc e/2008/07/molec ular-evide/ Broccoli extract bo osts skin’s defence against UV rays Scientists in the U .S. have found th at a broccoli extr act can help protect the skin a gainst ultraviolet (UV) rays, the pr imary cause of most skin can cers. The research team, in trials wit h mice and human volunteers , found that sulfo raphane, extracted from broc- coli sprouts and a pplied to the skin , helps protect cel ls against the redness and inflam mation created by exposure to the su n’s UV ra- diation. The hum an trial involved s ix volunteers, each exposed to UV ra diation on two patches on their b acks, one treated w ith the broccoli ex tract, the other no t. Skin redness was used as a mea sure of cell damag e. When the extra ct was applied dai ly during the th- ree days before UV exposure, UV-ind uced redness and swelling was reduc ed on average by 37 percent, tho ugh results varied from eight to 78 p ercent. http://www.cbc.c a/health/story/20 07/10/25/brocco li.html Niðurstöður rannsókna um hollustuáhrif brokkolís hafa verið birtar í fjölmiðlum um allan heim. Á netinu er einnig að finna fjölmargar greinar um ofureiginleika brokkolís og hið sérvirka ensím sem brokkolí inniheldur – sulforaphane.
