Certain dietary patterns may be related to the risk of CVD. We hypothesised that a plant-centred dietary pattern would be associated with a reduced risk of first myocardial infarction (MI). A case–control study of Norwegian men and postmenopausal women (age 45–75 years) was performed. A FFQ was administered, generally within 3 d after incident MI (n106 cases). Controls (n105) were frequency matched on sex, age and geographic location. On the FFQ, 190 items were categorised into thirty-five food groups and ana priorihealthy diet pattern score was created. We estimated OR using logistic regression with adjustment for energy intake, family history of heart disease, marital status, current smoking, education and age. Among food groups, the risk of MI was significantly higher persdof butter and margarine (OR 1·66 (95 % CI 1·12, 2·46)), and lower persdof tomatoes (OR 0·53 (95 % CI 0·35, 0·79)), high-fat fish (OR 0·57 (95 % CI 0·38, 0·86)), wine (OR 0·58 (95 % CI 0·41, 0·83)), salad (OR 0·59 (95 % CI 0·40, 0·87)), wholegrain breakfast cereals (OR 0·64 (95 % CI 0·45, 0·90)), cruciferous vegetables (OR 0·66 (95 % CI 0·47, 0·93)) and non-hydrogenated vegetable oil (OR 0·68 (95 % CI 0·49, 0·95)). An abundance of cases were found to have a lowa priorihealthy diet pattern score. A dietary pattern emphasising nutrient-rich plant foods and high-fat fish and low intransfatty acids was associated with decreased risk of MI among Norwegians.

OBJECTIVE: To analyze the association between dietary patterns and oral cancer. METHODS: The study, part of a Latin American multicenter hospital-based case-control study, was conducted in São Paulo, Southeastern Brazil, between November 1998 and March 2002 and included 366 incident cases of oral cancer and 469 controls, frequency-matched with cases by sex and age. Dietary data were collected using a food frequency questionnaire. The risk associated with the intake of food groups defined a posteriori, through factor analysis (called factors), was assessed. The first factor, labeled "prudent," was characterized by the intake of vegetables, fruit, cheese, and poultry. The second factor, "traditional," consisted of the intake of rice, pasta, pulses, and meat. The third factor, "snacks," was characterized as the intake of bread, butter, salami, cheese, cakes, and desserts. The fourth, "monotonous," was inversely associated with the intake of fruit, vegetables and most other food items. Factor scores for each component retained were calculated for cases and controls. After categorization of factor scores into tertiles according to the distribution of controls, odds ratios and 95% confidence intervals were calculated using unconditional multiple logistic regression. RESULTS: "Traditional" factor showed an inverse association with cancer (OR=0.51; 95% CI: 0.32; 0.81, p-value for trend 0.14), whereas "monotonous" was positively associated with the outcome (OR=1.78; 95% CI: 1.78; 2.85, p-value for trend <0.001). CONCLUSIONS: The study data suggest that the traditional Brazilian diet, consisting of rice and beans plus moderate amounts of meat, may confer protection against oral cancer, independently of any other risk factors such as alcohol intake and smoking.

AbstractPrevious studies have indicated that some food items and nutrients are associated with uric acid metabolism in humans. However, little is known about the role of dietary patterns in hyperuricaemia. We designed this case–control study to evaluate the associations between dietary patterns and newly diagnosed hyperuricaemia in Chinese adults. A total of 1422 cases and 1422 controls were generated from 14 538 participants using the 1:1 ratio propensity score matching methods. Dietary intake was assessed using a validated self-administered FFQ. Dietary patterns were derived by factor analysis. Hyperuricaemia was defined as concentrations of serum uric acid higher than 7 mg/dl (416·5 μmol/l) for men and 6 mg/dl (357 μmol/l) for women. Three dietary patterns were derived by factor analysis: sweet pattern; vegetable pattern; animal foods pattern. The animal foods pattern characterised by higher intake of an animal organ, seafood and processed meat products was associated with higher prevalence of newly diagnosed hyperuricaemia (Pfor trend<0·01) after adjustment. Compared with the participants in the lowest quartile of the animal foods pattern, the OR of newly diagnosed hyperuricaemia in the highest quartile was 1·50 (95 % CI 1·20, 1·87). The other two dietary patterns were not associated with the prevalence of newly diagnosed hyperuricaemia after adjustment. In conclusion, a diet rich in animal organ, seafood and processed meat products is associated with higher prevalence of newly diagnosed hyperuricaemia in a Chinese population. Further cohort studies and randomised controlled trials are required to clarify these findings.

AbstractBreast cancer is the most diagnosed cancer among women worldwide. Studies regarding diet and blood levels of vitamins and minerals in the breast cancer aetiology are limited and the results are inconclusive. We investigated the association between serum vitamin-mineral profiles (V-MPs) and breast cancer (BC) risk with including dietary patterns (DPs) and use of supplements. This case-control study involved 420 women aged 40–79 years from north-eastern Poland, including 190 newly-diagnosed breast cancer cases. The serum concentrations of vitamins (folate, cobalamin, 25(OH) vitamin D) and minerals (iron, calcium, magnesium) were marked in 129 post-menopausal women (82 controls, 47 cases) using an immune-analyser Cobas e411 and a Cobas Integra 400plus auto-analyser (Roche Diagnostics®), respectively. A posteriori V-MPs were derived with a Principal Component Analysis (PCA). Three PCA-driven DPs: ‘Non-Healthy’, ‘Prudent’, and ‘Margarine and Sweetened Dairy’ were described previously. A logistic regression analysis was performed. The odds ratios (ORs) and 95% confidence interval (95% CI) were calculated. Two serum V-MPs were identified. The ‘Folate-Cobalamin-Vitamin D’ profile was loaded heavily by the folate (factor loading 0.82), cobalamin (0.81) and vitamin D (0.49). The ‘Iron-Calcium’ profile was loaded heavily by the iron (0.81) and calcium (0.77). The ‘Magnesium-vitamin D’ profile was loaded heavily by the magnesium (0.92) and vitamin D (0.39). The risk of BC was lower by 88% (OR: 0.12; 95%Cl: 0.02–0.88; p < 0.05) in the upper tertile of the serum ‘Iron-Calcium’ profile compared to the bottom tertile. The risk of BC was lower by 67% (OR: 0.33; 95%Cl: 0.11–0.97; p < 0.05) at the level of serum 25(OH) vitamin D ≥ 24.6 ng/mL and lower by 68% (OR: 0.32; 95%Cl: 0.11–0.91; p < 0.05) at the level of serum calcium ≥ 9.6 mg/dL. There was the inverse association of the serum ‘Magnesium-Vitamin D’ profile with the risk of BC, which disappeared after adjustment for DPs. No significant association between BC risk and the serum ‘Folate-Cobalamin-Vitamin D’ profile and also folate, cobalamin, iron or magnesium considered separately was revealed. These findings highlight that the higher-adequate serum concentrations of both iron and calcium as well as close-to-adequate concentrations of calcium and vitamin D considered separately may protect against breast cancer among postmenopausal women, independently of dietary patterns and use of supplements. Therefore, women should be screened for blood concentrations of multiple vitamins and minerals in the breast cancer prevention.
