This study from Int J Cancer (circa Feb 2004) adds to the compelling body of evidence that diet is an important factor in the development of colon cancer. Advice: eat your vegetables and watch the red meat and refined carbohydrates.
Food groups and colon cancer risk in African-Americans and Caucasians
| Quote: |
.... case-control study. Incident cases of histologically confirmed colon
cancer, age 40-80 years, (n = 613) and matched controls (n = 996) were
interviewed in-person to ascertain potential colon cancer risk factors.
..... Multivariate logistic regression models estimated energy-adjusted and
non-energy adjusted odds ratios (OR).
Controls generally reported higher consumption (daily amount and weekly
frequency) of fruits, vegetables and dark green, deep yellow
fruits/vegetables, whereas cases consumed more refined carbohydrates and
fats, oils and snacks. Regardless of ethnic group or energy adjustment, high
and frequent vegetable consumption (particularly dark green vegetables) was
protective, consistent with 20-50% reductions in risk. In Caucasians, high
refined carbohydrate and red meat consumption (amount and frequency) was
associated with a statistically significant 2-fold increased risk in
non-energy adjusted models. In African-Americans, frequent intake of dairy
foods was associated with a doubling in risk (OR = 1.9, 95% CI = 1.1-3.4) in
non-energy-adjusted models, whereas frequent fruit consumption correlated
with a non-significant 30% lower risk.
These findings add to growing evidence that plant foods may protect against
colon cancer; however, the effects of the other food groups varied by ethnic
group and energy adjustment. |
