It is considered that fruit and vegetable (F&V) protect against oesophagus and gastric cancer (GC). However, 2 recent meta-analyses suggest that the strength of association on GC seems to be weaker for vegetables than for fruit and weaker in cohort than in case-control studies. No evidence exists from cohort studies about adenocarcinoma of oesophagus (ACO).(More)
OBJECTIVE This meta-analysis aims to quantitatively synthesize all studies that examine the association between adherence to a Mediterranean diet and risk of stroke, depression, cognitive impairment, and Parkinson disease. METHODS Potentially eligible publications were those providing effect estimates of relative risk (RR) for the association between(More)
Overall dietary patterns have been associated with health and longevity. We used principal component (PC) and cluster analyses to identify the prevailing dietary patterns of 99 744 participants, aged 60 years or older, living in nine European countries and participating in the European Prospective Investigation into Cancer and Nutrition (EPIC-Elderly(More)
BACKGROUND Premature mortality from cardiovascular diseases could be prevented by the effective control of hypertension. Nationwide data for the status of hypertension in the adult Greek population are not available. METHODS In the context of the Greek component of the European Prospective Investigation into Cancer and nutrition (EPIC), 26 913 volunteers,(More)
BACKGROUND Dietary factors are thought to have an important role in gastric and esophageal carcinogenesis, but evidence from cohort studies for such a role is lacking. We examined the risks of gastric cancer and esophageal adenocarcinoma associated with meat consumption within the European Prospective Investigation Into Cancer and Nutrition (EPIC) cohort.(More)
BACKGROUND Inflammation is an important component of carcinogenesis but little research has been conducted on whether inflammation markers can be predictive of cancer risk in humans. METHODS We analyzed C-reactive protein (CRP), a marker of inflammation, in plasma samples of 496 cases of cancer and 996 controls selected among participants in a prospective(More)
BACKGROUND Dietary supplement use is increasing, but there are few comparable data on supplement intakes and how they affect the nutrition and health of European consumers. The aim of this study was to describe the use of dietary supplements in subsamples of the 10 countries participating in the European Prospective Investigation into Cancer and Nutrition(More)
OBJECTIVE We have evaluated the effects on mortality of habitual low carbohydrate-high-protein diets that are thought to contribute to weight control. DESIGN Cohort investigation. SETTING Adult Greek population. SUBJECTS METHODS: Follow-up was performed from 1993 to 2003 in the context of the Greek component of the European Prospective Investigation(More)
OBJECTIVE To examine the relationship between body mass index (BMI) and waist-hip ratio (WHR) with serum levels of insulin-like growth factor-I (IGF-I), and its binding protein (IGFBP)-3. DESIGN Cross-sectional study on 2139 women participating in a case-control study on breast cancer and endogenous hormones. Data on lifestyle and reproductive factors(More)
BACKGROUND Previous studies suggest that high plasma concentrations of carotenoids, retinol, or tocopherols may reduce the risk of prostate cancer. OBJECTIVE We aimed to examine the associations between plasma concentrations of 7 carotenoids, retinol, alpha-tocopherol, and gamma-tocopherol and prostate cancer risk. DESIGN A total of 137,001 men in 8(More)
