Objective: Fruit and vegetable intake is inversely associated with cancer risk in many epidemiological studies. Accurate assessment of consumption of these foods is difficult, and biomarkers of intake would overcome several drawbacks of currently used dietary assessment methods. Therefore, we investigated the relation between plasma carotenoids and usual vegetable and fruit intake. Design: Plasma carotenoid concentrations were measured and vegetable, fruit and juice consumption was assessed by a...

The recommendation for fruit and vegetable intake includes eating a certain quantity as well as a variety. The evidence for eating a variety is limited. We examined the association with cancer in a prospective cohort study among 730 Dutch men aged 65-84 yr followed for 10 years, resulting in 138 cancer cases. The quantity of fruits and vegetables was assessed using a dietary history and the variety in intake was based on a food frequency questionnaire. Adherence to the recommended amounts of fru...

Our aim was to examine the relationship between fruit and vegetable consumption and lung cancer mortality in a cohort of European males. Around 1970, dietary intake of Finnish, Italian and Dutch middle-aged men was assessed using a cross-check dietary history. Complete baseline information was available for 3,108 men, of whom 1,578 were baseline smokers. We used Cox proportional hazard analyses to calculate risk estimates for the consumption in country-specific tertiles on lung cancer in smokers...

We examined the role of smoking and diet in the cross-cultural variation in lung-cancer mortality, using aggregated data of the Seven Countries Study, a follow-up study comprising 12,763 middle-aged men in 16 cohorts in Europe, the United States and Japan, which started around 1960. Smoking habits were assessed with a standardised questionnaire. Dietary intake was collected in random sub-samples of each cohort by the dietary record method. Cohort-specific 25-year lung-cancer mortality among all ...

Objective: We quantified the public health benefit of fruits and vegetables on the prevention of cancer and cardiovascular disease (CVD), using currently available human data. Design: We reviewed over 250 observational studies on cancer and CVD. Relative risks (RRs) for high versus low intake of fruits and vegetables were obtained. The preventable proportion of chronic diseases, i.e. the per cent of cases attributable to low consumption of fruits and vegetables, was estimated using three scenari...

Extended Abstract Unquestionably, cigarette smoking is the dominant risk factor for lung cancer. In addition, epidemiological studies consistently show an inverse association between fruit and vegetable consumption and lung cancer risk.1,2,3However, critics point at the possible role of residual confounding by smoking, and suggest that results from cohort studies may be less consistent compared with those from case-control studies.4Therefore, we examined the relationship between plant food consu...

Plant foods are generally considered to be beneficial for health. A higher consumption of fruits, and to a lesser extent vegetables, is consistently associated with a lower risk of stomach cancer. Results on the association between stomach cancer and grain consumption are less clear. We associated plant food consumption with 25-year stomach cancer mortality at population level in the Seven Countries Study. Around 1960,≷12,000 men aged 40-59 years from 7 countries and 16 cohorts were enrolled. In...
