Uživanje stročnic vsaj trikrat na teden in rjavega riža vsaj enkrat na teden zmanjšuje tveganje polipipov debelega črevesa za 33 odstotkov oziroma 40 odstotkov glede na raziskavo z Loma Linda univerzo je pokazala pred kratkim objavljena študija. Študija je pokazala tudi, da veliko zaužite hrane iz kuhane zelene zelenjave in suhega sadje vpliva na večjo zaščito.
Eating these foods is likely to decrease your risk for colon polyps, which would in turn decrease your risk for colorectal cancer," says lead author Yessenia Tantamango, MD, a post-doctoral research fellow with Adventist Health Study-2 at Loma Linda University. "While a majority of past research has focused on broad food groups, such as fruits and vegetables, in relation to colon cancer, our study focused on specific foods, as well as more narrowed food groups, in relation to colon polyps, a precursor to colon cancer. Our study confirms the results of past studies that have been done in different populations analyzing risks for colon cancer."
Colon cancer is the second leading cause of cancer death in the United States and the third most common cancer in both men and women, according to the American Cancer Society.
Results also show that consuming cooked green vegetables once a day or more, as compared to less than five times a week, was associated with a 24 percent reduction in the risk of rectal/colon polyps. Consuming dried fruit three times a week or more, versus less than once a week, was associated with a 26 percent reduced risk.
Rezultati tudi kažejo, da uživanje kuhane zelene zelenjava enkrat na dan ali več, v primerjavi z manj kot petkrat tedensko, zmanjša za 24 odstotkov možnosti nastanka polipov danke / debelega črevesa.
Študija je pokazala, da uživanje sušenega sadja trikrat na teden ali več, v primerjavi z manj kot enkrat na teden vpliva na zmanjša tveganja polipov za 26 odstotkov.
The protective effects of these foods could be due in part to their cancer-fighting agents, the study reported.
"Legumes, dried fruits, and brown rice all have a high content of fiber, known to dilute potential carcinogens," Dr. Tantamango says. "Additionally, cruciferous vegetables, such as broccoli, contain detoxifying compounds, which would improve their protective function."
Stročnice, suho sadje in rjavi riž vsebujejo visoko vrednost vlaknin.

Past studies examining the effect of meat intake and legumes on colon cancer have shown that people eating meat, associated with an increased risk of colon cancer, may receive some protection when they also consume legumes. Dr. Tantamango says this suggests that besides fiber content, there may be something else present in legumes that provides a protective effect.
Researchers analyzed data from 2,818 subjects who participated in Adventist Health Study-1 (administered from 1976-77) and who answered a follow-up survey 26 years later from Adventist Health Study-2. The first survey asked respondents to indicate how often, on average, they consumed specific foods. The follow-up survey asked respondents who had undergone colonoscopies to indicate physician-diagnosed colorectal polyps. During the 26-year follow-up, 441 cases of rectal/colon polyps were identified.
The study assessed several possible confounding factors, including a family history of colorectal cancer, education, physical activity level, alcohol intake, smoking, constipation, intake of sweets, pain medication, and multivitamins, as well as different food variables. The study then adjusted for those factors that were shown to distort the effect of the foods and food groups under study. About 25 foods and food groups in total were examined.
Dr. Tantamango says there is a need for future studies to examine foods shown to reduce the risk of colon polyps, since it is possible that interactions between various nutrients with anti-cancerous properties will be better able to explain these findings.
Polipi danke in širokega črevesa ter družinska polipoza
Ponavljajoča se kri v blatu lahko izvira iz krvavečega polipa. Višje v črevesju je polip temnejša je kri, saj se kri na poti do zadnjika že delno razgradi in pomeša z blatom. Polipi so različno veliki izrastki, pojavljajo se posamezno ali v večjem številu. Vsak polip, ki ga najdemo pri rektoskopiji ali koloskopiji je potrebno odstraniti, saj se nekatere vrste polipov čez več let rakasto spremenijo. Polipi so praviloma dovolj majhni, da jih lahko odžgemo med samo preiskavo (rektoskopija, koloskopija) in operacija ni potrebna. Ker se lahko pojavljajo novi polipi je potrebno bolnike redno naročati na koloskopske preglede (na 2 do 3 leta). Priporočamo, da tudi drugi člani bolnikove družine (starši, bratje, sestre, otroci) najkasneje po 40 letu starosti preventivno opravijo koloskopijo, saj obstaja dedna nagnjenost za pojav polipov.
Posebna oblika bolezni je družinska polipoza širokega črevesa, kjer so polipi na gosto posejani po širokem črevesu. Pri tej obliki bolezni je potrebno preventivno odstraniti celotno široko črevo, najkasneje do 25 .- 30 leta starosti, saj se sicer razvije rak širokega črevesa. Družinski člani bolnika z družinsko polipozo morajo biti redno koloskopirani že v najstniškem obdobju, saj gre za avtosomno dominantno dedovanje.
