- The relationships between coffee, tea, and sugar-sweetened carbonated soft drink consumption and colon cancer risk remain unresolved. We investigated prospectively the association between coffee, tea, and sugar-sweetened carbonated soft drink consumption and colon cancer risk in a pooled analysis of primary data from 13 cohort studies. Among 731 441 participants followed for up to 6-20 years, 5604 incident colon cancer case patients were identified. Study-specific relative risks (RRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models and then pooled using a random-effects model. All statistical tests were two-sided. Compared with nonconsumers, the pooled multivariable relative risks were 1.07 (95% CI = 0.89 to 1.30, P-trend = .68) for coffee consumption greater than 1400 g/d (about six 8-oz cups) and 1.28 (95% CI = 1.02 to 1.61, P-trend = .01) for tea consumption greater than 900 g/d (about four 8-oz cups). For sugar-sweetened carbonated soft drink consumption, the pooled multivariable relative risk comparing consumption greater than 550 g/d (about 18 oz) to nonconsumers was 0.94 (95% CI = 0.66 to 1.32, P-trend = .91). No statistically significant between-studies heterogeneity was observed for the highest category of each beverage consumed (P > .20). The observed associations did not differ by sex, smoking status, alcohol consumption, body mass index, physical activity, or tumor site (P > .05). Drinking coffee or sugar-sweetened carbonated soft drinks was not associated with colon cancer risk. However, a modest positive association with higher tea consumption is possible and requires further study.

- Epidemiologic studies of pancreatic cancer risk have reported null or nonsignificant positive associations for obesity, while associations for height have been null. Waist and hip circumference have been evaluated infrequently. A pooled analysis of 14 cohort studies on 846,340 individuals was conducted; 2,135 individuals were diagnosed with pancreatic cancer during follow-up. Study-specific relative risks (RRs) and 95% confidence intervals (CIs) were calculated by Cox proportional hazards models, and then pooled using a random effects model. Compared to individuals with a body mass index (BMI) at baseline between 21-22.9 kg/m(2), pancreatic cancer risk was 47% higher (95% CI:23-75%) among obese (BMI >= 30 kg/m(2)) individuals. A positive association was observed for BMI in early adulthood (pooled multivariate [MV]RR = 1.30, 95%CI = 1.09-1.56 comparing BMI >= 25 kg/m(2) to a BMI between 21 and 22.9 kg/m(2)). Compared to individuals who were not overweight in early adulthood (BMI < 25 kg/m(2)) and not obese at baseline (BMI < 30 kg/m(2)), pancreatic cancer risk was 54% higher (95%CI = 24-93%) for those who were overweight in early adulthood and obese at baseline. We observed a 40% higher risk among individuals who had gained BMI >= 10 kg/m(2) between BMI at baseline and younger ages compared to individuals whose BMI remained stable. Results were either similar or slightly stronger among never smokers. A positive association was observed between waist to hip ratio (WHR) and pancreatic cancer risk (pooled MVRR = 1.35 comparing the highest versus lowest quartile, 95%CI = 1.03-1.78). BMI and WHR were positively associated with pancreatic cancer risk. Maintaining normal body weight may offer a feasible approach to reducing morbidity and mortality from pancreatic cancer.

- Purpose: Our aim was examine the association between black tea consumption and risk of total stroke and stroke types in a prospective study. Methods: A total of 74,961 Swedish women and men who were free of cardiovascular disease and cancer at baseline in 1997 were followed up through December 2008. Tea consumption was assessed with a questionnaire at baseline. Stroke cases were ascertained from the Swedish Hospital Discharge Registry. Results: During a mean follow-up of 10.2 years, we ascertained 4089 cases of first stroke, including 3159 cerebral infarctions, 435 intracerebral hemorrhages, 148 subarachnoid hemorrhages, and 347 unspecified strokes. After adjustment for other risk factors, high tea consumption was associated with a significantly lower risk of total stroke; however, there was no dose response relation (P for trend = .36). Compared with no tea consumption, the multivariable relative risk for four or more cups per day (median, 5) was 0.79 (95% confidence interval [CI], 0.62-0.998). The corresponding relative risks were 0.80 (95% CI, 0.61-1.04) for cerebral infarction and 0.68 (95% Cl, 0.35-1.30) for hemorrhagic stroke. Conclusions: These findings suggest that daily consumption of four or more cups of black tea is inversely associated with risk of stroke. (C) 2013 Elsevier Inc. All rights reserved.

- Objective: To investigate the association between chocolate consumption and risk of stroke in men and conduct a meta-analysis to summarize available evidence from prospective studies of chocolate consumption and stroke. Methods: We prospectively followed 37,103 men in the Cohort of Swedish Men. Chocolate consumption was assessed at baseline using a food-frequency questionnaire. Cases of first stroke were ascertained from the Swedish Hospital Discharge Registry. For the meta-analysis, pertinent studies were identified by searching the PubMed and EMBASE databases through January 13, 2012. Study-specific results were combined using a random-effects model. Results: During 10.2 years of follow-up, we ascertained 1,995 incident stroke cases, including 1,511 cerebral infarctions, 321 hemorrhagic strokes, and 163 unspecified strokes. High chocolate consumption was associated with a lower risk of stroke. The multivariable relative risk of stroke comparing the highest quartile of chocolate consumption (median 62.9 g/week) with the lowest quartile (median 0 g/week) was 0.83 (95% CI 0.70-0.99). The association did not differ by stroke subtypes. In a meta-analysis of 5 studies, with a total of 4,260 stroke cases, the overall relative risk of stroke for the highest vs lowest category of chocolate consumption was 0.81 (95% CI 0.73-0.90), without heterogeneity among studies (p = 0.47). Conclusion: These findings suggest that moderate chocolate consumption may lower the risk of stroke. Neurology (R) 2012;79:1223-1229

- Background and Purpose-Coffee consumption has been inconsistently associated with stroke incidence and mortality in previous studies. We investigated the association between coffee consumption and stroke incidence in the Swedish Mammography Cohort. Methods-We prospectively followed of 34 670 women without a history of cardiovascular disease or cancer at baseline in 1997. Coffee consumption was assessed in 1997 using a self-administered questionnaire. Incident stroke cases were ascertained from the Swedish Hospital Discharge Registry. Results-During a mean follow-up of 10.4 years, we ascertained 1680 stroke events, including 1310 cerebral infarctions, 154 intracerebral hemorrhages, 79 subarachnoid hemorrhages, and 137 unspecified strokes. After adjustment for other risk factors, coffee consumption was associated with a statistically significant lower risk of total stroke, cerebral infarction, and subarachnoid hemorrhage but not intracerebral hemorrhage. The multivariable relative risks of total stroke across categories of coffee consumption (< 1 cup/ day, 1 to 2 cups/day, 3 to 4 cups/day, and >= 5 cups/day) were 1.00, 0.78 (95% CI, 0.66 to 0.91), 0.75 (95% CI, 0.64 to 0.88), and 0.77 (95% CI, 0.63 to 0.92, respectively; P for trend=0.02). The association between coffee consumption and cerebral infarction was not modified by smoking status, body mass index, history of diabetes or hypertension, or alcohol consumption. Conclusions-These findings suggest that low or no coffee consumption is associated with an increased risk of stroke in women. (Stroke. 2011;42:908-912.)

- Background and Purpose-Epidemiological studies of the associations of low-fat dairy and specific dairy food consumption with risk of stroke are sparse. Our aim was to examine the association between consumption of total, low-fat, full-fat, and specific dairy foods and risk of stroke in a prospective cohort study. Methods-We followed 74 961 Swedish women and men who were free from cardiovascular disease and cancer and who completed a 96-item food frequency questionnaire in 1997. Incident cases of stroke were ascertained from the Swedish Hospital Discharge Registry. Results-During a mean follow-up of 10.2 years, we ascertained 4089 cases of stroke, including 3159 cerebral infarctions, 583 hemorrhagic strokes, and 347 unspecified strokes. Consumption of low-fat dairy foods was inversely associated with risk of total stroke (P for trend=0.03) and cerebral infarction (P for trend=0.03). The multivariable relative risks for the highest compared with the lowest quintile of low-fat dairy consumption were 0.88 (95% CI, 0.80-0.97) for total stroke and 0.87 (95% CI, 0.78-0.98) for cerebral infarction. Consumption of total dairy, full-fat dairy, milk, sour milk/yogurt, cheese, and cream/creme fraiche was not associated with stroke risk. Conclusions-These results suggest that low-fat dairy consumption is inversely associated with the risk of stroke. (Stroke. 2012;43:1775-1780.)

- Background: Whether intakes of dietary fat and cholesterol are associated with risk of stroke remain unclear. We examined the associations between intakes of total fat, specific types of fat, and cholesterol and risk of stroke in a prospective cohort of women. Methods: The study population consisted of 34,670 women, aged 49-83 years, in the Swedish Mammography Cohort who were free of cardiovascular disease and completed a food-frequency questionnaire in 1997. Cox proportional hazard regression models were used to estimate relative risks (RR) with 95% confidence intervals (CI). Results: During a mean follow-up of 10.4 years, we ascertained 1680 stroke events, including 1310 cerebral infarctions, 233 hemorrhagic strokes, and 137 unspecified strokes. After adjustment for other stroke risk factors, intake of long-chain omega-3 polyunsaturated fatty acids (PUFA) was inversely associated with risk of total stroke. The multivariable RR of total stroke for the highest compared with the lowest quintile of long-chain omega-3 PUFA intake was 0.84 (95% CI, 0.72-0.99; P for trend = 0.04). Dietary cholesterol was positively associated with risk of total stroke (highest versus lowest quintile: RR = 1.20; 95% CI, 1.00-1.44; P for trend = 0.01) and cerebral infarction (corresponding RR = 1.29; 95% CI, 1.05-1.58; P for trend = 0.004). Total fat, saturated fat, monounsaturated fat, polyunsaturated fat, alpha-linolenic acid, and omega-6 PUFA intakes were not associated with stroke. Conclusions: These findings suggest that intake of long-chain omega-3 PUFAs is inversely associated with risk of stroke, whereas dietary cholesterol is positively associated with risk.

- Background: A high protein intake may reduce the risk of stroke but epidemiologic data on protein intake in relation to stroke risk are limited and inconsistent. Our objective was to test the hypothesis that protein intake would be inversely associated with risk of stroke. Methods and results: We conducted a population-based prospective cohort study consisting of 34,670 Swedish women who were free of cardiovascular disease and cancer in 1997. Diet was assessed with a food-frequency questionnaire. Incident cases of stroke were ascertained from the Swedish Hospital Discharge Registry. We estimated relative risks (RR) with 95% confidence intervals (CI) using Cox proportional hazard regression model. During 10.4 years of follow-up, 1680 stroke events were identified, including 1310 cerebral infarctions, 154 intracerebral hemorrhages, 79 subarachnoid hemorrhages, and 137 unspecified strokes. Intake of total and animal protein, but not vegetable protein, was statistically significantly inversely associated with risk of total stroke and cerebral infarction after adjustment for other risk factors for stroke. The multivariable RRs of total stroke for the highest versus lowest quintile of intake were 0.74 (95% CI: 0.61, 0.91; P for trend = 0.006) for total protein and 0.71 (95% CI: 0.57, 0.88; P for trend = 0.01) for animal protein. The associations were stronger in women with a history of hypertension (RR of total stroke = 0.56; 95% CI: 0.40, 0.78 for highest versus lowest quintile of total protein). Conclusion: These findings suggest that dietary protein intake is inversely associated with risk of stroke in women with hypertension. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

- Background: Epidemiologic studies of fish consumption in relation to risk of stroke have yielded inconsistent results. Objective: In this study, we examined the association between fish consumption and stroke incidence in women. Design: We analyzed data from a population-based prospective cohort of 34,670 women in the Swedish Mammography Cohort who were free of cardiovascular disease and cancer at baseline. Information on fish consumption was obtained by a self-administered questionnaire in 1997. Incident cases of stroke were ascertained from the Swedish Hospital Discharge Registry. We used Cox proportional hazards regression to estimate relative risks (RRs) and 95% CIs. Results: Over a mean follow-up of 10.4 y, we ascertained 1680 incident cases of stroke, including 1310 cerebral infarctions, 233 hemorrhagic strokes, and 137 unspecified strokes. Fish consumption was significantly inversely associated with risk of total stroke but not with cerebral infarction or hemorrhagic stroke. Compared with women in the lowest quintile of fish consumption (< 1.0 serving of fish/wk), the multivariable RR of total stroke for women in the highest quintile (> 3.0 servings of fish/wk) was 0.84 (95% CI: 0.71, 0.98; P for trend = 0.049). Consumption of lean fish but not of other fish types was inversely associated with risk of stroke. The multivariable RR of total stroke was 0.67 (95% CI: 0.49, 0.93; P for trend = 0.07) for >= 3 servings of lean fish/wk compared with that for no consumption. Conclusion: These results suggest that the consumption of fish, especially of lean fish, may reduce risk of stroke in women. This trial was registered at clinicaltrials.gov as NCT01127698. Am J Clin Nutr 2011;93:487-93.
