Various factors including genetic background, familial history cancer, race and ethnicity, smocking, alcohol consumption, relative body weight, lifestyle and environmental factors have been proposed as main contributors for cancer incidence. Dietary patterns and food components are considered as main modifiable risk factors for development of cancer. Several studies showed that dietary intake of macro and micronutrients as well as various food groups including fruits and vegetables, phytochemical-rich foods, dairy and meat products may be related to the risk of cancer. Protective effects of some dietary patterns such as prudent/healthy pattern, plant-based and Mediterranean diet, and some food groups such as fruits and vegetables, whole grains, nuts and fish meat against the development of cancer has been reported. On the other hand, such dietary pattern including Western dietary pattern and higher consumption of processed foods, fast foods and unhealthy snacks, refined grains, saturated and trans fats have been known as risk for development of cancer. The proposed special issue "American Journal of Life Sciences" could be contains research articles as well as review articles regarding the diet, nutrition and food science and the risk of cancer.

Abstract: Objective: Epidemiologic data do not provide consistent evidence for an association between consumption of meat and breast cancer risk. We conducted a hospital-based case-control study during April and July 2010 among Iranian women to investigate associations between dietary meat intake, its types and breast cancer risk. Methods: One-hundred consecutively recruited cases with newly diagnosed breast cancer were frequency matched to 175 controls by age. Dietary intake was assessed by using a validated semi-quantitative food frequency questionnaire. Odds ratios and 95% confidence interval were obtained by using multiple logistic regression models adjusted for various potentially confounding variables. Results: The mean age of participant was 46.2±8.9 and 45.9±9.4 y in cases and controls, respectively. After adjustment of potential confounders, no association was found between total meat intake and the odds of breast cancer, but the risk of breast cancer in the forth quartile of red meat intake, compared with first quartile, significantly increased (OR=2.43, 95% CI=1.11-5.32). Consumption of poultry > 212 g/week significantly decreased the risk of breast cancer. Higher intake of fish meat decreased the odds of breast cancer (P for trend<0.05), whereas higher intake of processed meat was accompanied with increased the risk of breast cancer (P for trend<0.05). Conclusion: We found a positive association between dietary intake of red meat and processed meat products with the odds of breast cancer, as well as protective effects of fish and poultry intake with breast cancer.Abstract: Objective: Epidemiologic data do not provide consistent evidence for an association between consumption of meat and breast cancer risk.

Abstract: There is growing evidence that healthy dietary patterns including Mediterranean, prudent, traditional and plant-food based dietary patterns could have favorable effects in breast cancer prevention but there are inconsistencies in this regard. In the current study we reviewed the current evidences in relation to healthy dietary patterns and the risk of breast cancer. Both positive and negative association between Mediterranean dietary pattern and scores as well as prudent and traditional diet and breast cancer risk were observed in case-control and cohort studies. These conflicting findings might be explained by several issue including different dietary assessment methods, different definitions of Mediterranean dietary pattern and score, measurement errors, race differences, and potential confounding variables adjusted in the models. The healthy dietary patterns with high loading of fruits, vegetables, whole grains and legumes had been mainly accompanied with a considerable reduced risk of breast cancer in different races. It should be noted that menopausal and tumor's hormone receptor status, as well as body mass index of women had determinant role in the association of healthy dietary patterns and breast cancer risk. Protective effects of healthy dietary patterns against breast cancer were mainly observed in women with normal body weight (BMI<25 kg/m2). Further studies are required to clear the associations of dietary patterns and breast cancer risk.Abstract: There is growing evidence that healthy dietary patterns including Mediterranean, prudent, traditional and plant-food based dietary patterns could have favorable effects in breast cancer prevention but there are inconsistencies in this regard.
