BACKGROUND Red meat and processed meat have been associated with carcinogenesis at several anatomic sites, but no prospective study has examined meat intake in relation to a range of malignancies. We investigated whether red or processed meat intake increases cancer risk at a variety of sites. METHODS AND FINDINGS The National Institutes of Health(More)
Although the relation between red and processed meat intake and colorectal cancer has been reported in several epidemiologic studies, very few investigated the potential mechanisms. This study examined multiple potential mechanisms in a large U.S. prospective cohort with a detailed questionnaire on meat type and meat cooking methods linked to databases for(More)
This study examined the cardiovascular mechanisms governing differential blood pressure changes during the emotions of joy, sadness, fear, and anger. Heart rate, blood pressure, stroke volume, peripheral vascular resistance, cardiac output, and indices of myocardial contractility were measured during fear, anger, joy, sadness, physical action, and neutral(More)
Animal studies have shown that dietary intake of benzo[a]pyrene (BaP), a polycyclic aromatic hydrocarbon (PAH), causes increased levels of tumors at several sites, particularly in the upper gastrointestinal tract. However, the role of dietary intake of BaP and cancer in humans is not clear. We created a BaP database of selected food products that could be(More)
Dietary guidelines advise consumers to limit intake of red meat and choose lean protein sources, such as poultry and fish. Poultry consumption has been steadily increasing in the United States, but the effect on cancer risk remains unclear. In a large U.S. cohort, we prospectively investigated poultry and fish intake and cancer risk across a range of(More)
CONTEXT Consumption of red and processed meat has been associated with colorectal cancer in many but not all epidemiological studies; few studies have examined risk in relation to long-term meat intake or the association of meat with rectal cancer. OBJECTIVE To examine the relationship between recent and long-term meat consumption and the risk of incident(More)
Fruit and vegetable intake has been linked to bladder cancer risk; however, evidence for other foods or specific dietary factors is inconclusive. The association between diet and bladder cancer risk was evaluated among 912 incident bladder cancer cases and 873 controls in Spain. Data were consistent with a reduced bladder cancer risk associated with high(More)
A case-control study of colorectal cancer, consisting of 157 cases and 380 controls matched by sex, ethnicity, decade of age and county of residence was performed to explore the associations between environmental exposure, metabolic polymorphisms and cancer risk. Participants were required to provide a blood sample, undergo caffeine phenotyping and complete(More)
OBJECTIVES Red and processed meats could increase cancer risk through several potential mechanisms involving iron, heterocyclic amines, polycyclic aromatic hydrocarbons, and N-nitroso compounds. Although there have been multiple studies of meat and colorectal cancer, other gastrointestinal malignancies are understudied. METHODS We estimated hazard ratios(More)
OBJECTIVES No previous study has concurrently assessed the associations between meat intake, meat-cooking methods and doneness levels, meat mutagens (heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons), heme iron, and nitrite from meat and colorectal adenoma in asymptomatic women undergoing colonoscopy. METHODS Of the 807 eligible women in a(More)
