SOJA y CANCER: artículos USA
1. Investigadores del Hospital Infantil y el Centro de Investigación de Okland en Estados Unidos han identificado una nueva clase de agentes terapéuticos que se encuentran de forma natural en la soja que previenen y posiblemente sirvan para tratar el cáncer de colon. Los resultados de su trabajo se publican en la revista 'Cancer Research'.Los 'sphingadienes' (SD) son moléculas de lípidos naturales que se encuentran en la soja y que la investigación muestra que podrían ser claves en la lucha contra el cáncer de colon.Posteriores investigaciones indicaron que los niveles elevados de SDs en realidad inducían la muerte de células mutantes en la mosca, revelando que eran componentes citotóxicos (tóxicos para las células).Beneficios de la soja
* Por su aporte en isoflavonas (fitoestrógenos) regula el flujo de hormonas femeninas, reduciendo los sofocos de la menopausia y la pérdida de minerales en los huesos.
* Regula la tasa de azúcar en la sangre, siendo aconsejada en diabéticos.
* Previene problemas del corazón y del sistema circulatorio.
* Reduce el colesterol gracias a su aporte en Lecitina e isoflavonas.
* Excelente fuente de proteínas, la cual se convierte en un complemento idóneo en dietas vegetarianas.
* Preventiva de cáncer de próstata.
2.Según investigadores/as del Georgetown University Medical Center quienes publicaron su estudio en el British Journal of Cancer.Las evidencias en estudios de animales y humanos a favor del uso del genisteinCáncer. El genistein es un químico potente que se encuentra en la soja, y puede llegar a ser una protección contra el desarrollo del Cáncer de mama. Es especialmente beneficioso para la prevención del Cáncer de mama si es consumido durante la pubertad.
Según dijo Leena Hilakivi-Clarke, investigadora del grupo y oncóloga, es de vital importancia el prevenir desde la juventud con esta comida bioactiva, y que cuando se den cuenta por qué es así podrán incluso llegar a una cura, y no sólo a la prevención.

Dietary fat and breast cancer-Dieta grasa diaria y cancer de pecho
Annu Rev Nutr. 2000;20:221-48.

Abstract
One of the most often studied associations in epidemiology is dietary fat and breast cancer risk. That migrants from low-risk countries increase their risk on immigrating to higher-risk countries suggests that some modifiable lifestyle or environmental factor is responsible for the development of breast cancer. Although early international correlational studies and experimental animals studies support dietary fat as a risk factor for breast cancer, more recent data from case-control studies and cohort studies have been equivocal, thus the analytical data do not support a strong positive association. The conflicting results from analytic studies may be due to methodologic issues associated with study design, dietary assessment tools, measurement error, improper statistical analyses, and a lack of heterogeneity in fat intake among the study population. Moreover, current dietary questionnaires may be inadequate in capturing true dietary intakes or capturing the risk with exposure during earlier periods of a woman's life. Although two large clinical trials investigating the fat/breast cancer relationships issue are underway, researchers are generally skeptical at their ability to detect an independent association between fat and breast cancer risk. Further epidemiologic studies using current methodology may not prove to be fruitful in generating definitive answers to shed light on this controversial issue. In addition, rather than concentrating on dietary fat, researchers should focus on diets that are not only low in saturated fat, but also high in fruit and vegetable consumption. Researchers should take advantage of advances in molecular and genetic technology for a different perspective in examining the issue. For example, markers of susceptibility to breast cancer that can detect women at higher risk for breast cancer may be helpful in clarifying the role of dietary fat. More comprehensive and multiple approaches to studying dietary factors and breast cancer are recommended.

Consumption of dairy products and the risk of breast cancer: a review of the literature.
Consumption of dairy products and the risk of breast cancer: a review of the literature.

Abstract
Differences in eating patterns and breast cancer rates across countries suggest that several dietary components, including dairy products, could affect breast cancer risk. However, dairy products are a diverse food group in terms of the factors that could potentially influence risk. Some dairy products, such as whole milk and many types of cheese, have a relatively high saturated fat content, which may increase risk. Moreover, milk products may contain contaminants such as pesticides, which have carcinogenic potential, and growth factors such as insulin-like growth factor I, which have been shown to promote breast cancer cell growth. In contrast, the calcium and vitamin D contents of dairy products have been hypothesized to reduce breast cancer risk. We reviewed the current epidemiologic literature on the relation between dairy product intakes and breast cancer risk, focusing primarily on the results of cohort and case-control studies. Most of the studies reviewed showed no consistent pattern of increased or decreased breast cancer risk with a high consumption of dairy products as a whole or when broken down into high-fat and low-fat dairy products, milk, cheese, or butter. Measurement error may have attenuated any modest association with dairy products. The available epidemiologic evidence does not support a strong association between the consumption of milk or other dairy products and breast cancer risk.

Abstract
EPIC is a prospective multi-center study coordinated by the International Agency for Research on Cancer (IARC) operating under the WHO which commenced in 1993 with the collecting of data and blood samples at twenty-three centers in ten European countries (Germany, Denmark, Spain, France, Greece, the Netherlands, Italy, Norway, the United Kingdom and Sweden). In Spain, this study was conducted in five geographic areas (Asturias, Granada, Guipuzcoa, Murcia and Navarre). This study included a total of 519,978 individuals (366,521 of whom were females), blood samples for laboratory analysis being available for a total of 385,719 of these individuals. To date, a total of 24,195 incident cancer cases have been identified. The results of the food intake comparison among the twenty-three European centers were published in 2002, in a European Nutrition journal supplement. The initial EPIC results concerning the relationship between diet and cancer show the intake of fiber, fruits and vegetables to have an effect on protect against colon and rectal cancer, the intake of fruits to have an effect on protect against lung cancer and the intake of fruits and vegetables on the upper digestive tract, whilst a high intake of fruits and vegetables has been shown to have no effect on prostate cancer. Using a seven-day diary for evaluating saturated fat intake, a high intake of saturated fats has been shown to increase the risk of breast cancer.
