Adding a portion of dried beans into your diet may have a potential effect in reduced risk of cancers onset, according to the Division of Cancer Prevention, National Cancer Institute.
Dried beans are a nutritionally mighty member of the legume family, belonging to the family Fabaceae.
The healthy sources of dried legume, including protein, fibers, vitamins and minerals such as dietary fiber, fat, protein, vitamin A ( beta-carotene, lutein and zeaxanthin), B vitamins, vitamin C, calcium, iron, magnesium, phosphorus, potassium, ... and zinc can be included in any one diet,
Certain genetic mutations may have significant influences in the risk of cancers, such as BRCA1 and BRCA2 genes which can elevate the risk of breast and ovarian cancers.
According to statistic, women who carry mutated gene BRCA1 and 2 have a 50 to 85 percent increased risk of developing the disease by age of 70.
Other causes of cancer are unknown, however, researchers suggested that smoking and use of tobacco, unhealthy diet, family history, inactive physical activity, long-term exposure to sun and other types of radiation, infected viruses, and infectious diseases are some of the potential risk factors that may have a strong impact on the development of cancers.
Cancer is a class of diseases characterized by cell growth uncontrollably and disorderly, affecting all the organs and tissue.
Depending on its invasive nature, some cancers can travel a distance away from the original site to infect other parts of the body.
In the study to investigate 490,802 United States participants of the NIH-AARP Diet and Health cohort using Cox proportional hazard models adjusted for potential confounders and during 2,193,751 person-years of follow-up from 1995/1996-2000, researchers found that
*. Intake of vegetables shows a significant effect in reduced risk of certain types of cancer.
* The relative hazard ratio risk of cancers was reduced to .95 in compared to control
*. Risk of cancers is reduced substantially as shown in the highest tertile of Leguminosae group (dried beans, string beans, and peas, 0.80, 0.67-0.96) compared to other groups.
Dried bean and string bean with abundant fiber scored the lower and lowerest relative risk ratio in compared to peas and other kinds of vegetables.
Further analysis of diets of African-American men and women, undergoing colonoscopies in order to examine the relationship between selected dietary factors and the risk for colon polyps, according to the multiple logistic regression model used to adjust for potential confounding variables and to determine which factors influence colorectal adenoma risk, researchers said, " consumption of legumes such as dried beans, split peas, or lentils was negatively associated with risk (of cancers)" and "Legumes are a good source of dietary fiber and of phytochemical compounds that may play a role in reducing adenoma formation or growth".
Once again, dried beans exerted the highest effect in reduced risk of colorectal adenoma in compared to other types of legume.
Interestingly, in broader scope of further exploration of the association between legume intake and cancer risk in a case-control study of 11 cancer sites in Uruguay between 1996 and 2004, including 3,539 cancer cases and 2,032 hospital controls, researchers suggested, intake of legume including dried peas demonstrate a substantially decreased risk of stomach and prostate cancer and other forms of cancer, including
*. Cavity and pharynx cancer had a relative odd risk ratio of OR=0.48
*. Esophagus cancer with OR = 0.54
*. Larynx cancer with OR = 0.55
*. Upper aerodigestive tract cancer with OR = 0.50
*. Stomach cancer with OR = 0.69
*. Colorectum cancer with OR = 0.43
*. Kidney cancer relative had an odd risk ratio of.OR = 0.41
* With relative odd risk ratio of .68 on all sites combined
After adjusting to other risk factors researchers concluded, "Higher intake of legumes was associated with a decreased risk of several cancers including those of the upper aerodigestive tract, stomach, colorectum, and kidney, but not lung, breast, prostate or bladder".
These results suggested that the protective effect of dried beans in inhibited most types of cancer occurrence may be a result of improvement of host cells integrity against alternation of cells DNA transcription in the induction of cancer.
