Groenten en fruit bieden bescherming tegen dikkedarmkanker

Research Question:
Studies of the relationship between a particular food or nutrient and the risk of getting colon cancer (colorectal cancer) give inconsistent results. It was therefore carried out this review article.

Which nutritional patterns provide protection against colorectal cancer?

Study Design:
This overview article contained 8 prospective cohort studies and case-control studies 8.
The relative risk with 95% CI and the random-effects model were used to the relationships between the different dietary patterns and getting colon cancer see.

Results and conclusions:
The researchers found that a diet with a high alcohol consumption the chance of getting colon cancer non-significant reduced by 4%. In other words, the relative risk was 0.96 [95% CI = 0.82-1.12]. Non-significant is, it can be said with 95% reliability that the reduced risk was not due to a diet with a high alcohol consumption. Non-significant means, in practice, no connection.

The researchers found that a diet with lots of fruits and vegetables the chance of getting colon cancer significantly reduced by 20%. In other words, the relative risk was 0.80 [95% CI = 0.70-0.90]. Significant is, it can be said with 95% reliability that the reduced risk was due to a diet with lots of fruits and vegetables.

The researchers found that a diet with a high red meat and processed meat consumption the chance of getting colorectal cancer increased significantly by 29%. In other words, the relative risk was 1.29 [95% CI = 1.13-1.48]. Significant is, it can be said with 95% reliability that the increased risk was due to a diet with a high red meat and processed meat consumption.

The researchers concluded that a diet with lots of fruits and vegetables reduced the chance of getting colon cancer while a diet with a high red meat and processed meat consumption increased the chance of getting colon cancer
