Good news for “coffee lovers” : several studies suggest that moderate coffee intake (a source of antioxidant), might help prevent numerous forms of cancers, from prostate cancer to various gastrointestinal cancers.


Coffee consumption and prostate cancer risk: an updated meta-analysis.


Many epidemiological studies have been conducted to explore the association between coffee consumption and prostate cancer. However, the results remain inconsistent. We performed a large meta-analysis of relevant studies to derive a more precise estimation of this relationship.


Systematic searches of PubMed and several other databases up to June 2013 were retrieved. All epidemiologic studies regarding coffee consumption and prostate cancer risk were included, and odds ratios (ORs) with 95 % confidence intervals (CIs) were calculated to estimate the strength of the association.


Twelve case-control studies involving 7,909 prostate cancer cases and 9,461 controls and nine cohort studies involving 455,123 subjects were included in our analysis. Compared with the lowest category, the unstratified highest category of coffee consumption showed a significance reduction in prostate cancer risk of a fixed-effects model (OR 0.91, CI 0.86-0.97). A borderline significant influence was also found when the stratified highest category (US ?4, Europe ?5) of coffee consumption was compared with the reference category (OR 0.96, CI 0.92-1.00), but no relationships were observed for the other two categories. In another analysis conducted by coffee consumption and prostate cancer stage and Gleason grade, our results showed a significant inverse association in all categories of prostate cancer except Gleason <7 grade in a fixed-effects model; the results remained the same, except for advanced prostate cancer, in a random-effects model.


Our meta-analysis suggests that coffee consumption may not only be associated with a reduced risk of overall prostate cancer, but also inversely associated with fatal and high-grade prostate cancer.


Impact of lifestyle factors and nutrients intake on occurrence of gastrointestinal cancer in Tunisian population.

This study aims to show the relationship between lifestyle and risk of colorectal and gastric cancers in Tunisian population. The food frequency survey method was used to obtain information about the dietary intake and way of life. Nutrients intake was calculated according to the food composition database. According to our results, the consumption of vegetables, fruits, fish, as well as coffee seems to be protective against digestive cancer, while the consumption of citrus and olive oil is protective against gastric cancer. Tobacco, alcohol, and tea represent a risk against gastrointestinal cancer. Highly educated people are more conscious of the crucial role of prevention. In addition, nutrients were significantly associated with colorectal and gastric cancer. The findings suggest that lifestyle is associated with a risk of gastrointestinal cancer. Moreover, higher intake of nutrients from foods was observed more in cases with colorectal and gastric cancer than controls.
