Caause diet meaat nutrition have been studied in relationship with breast cancer risk, as the great variation among different baby love quotes in breast cancer incidence could possibly be explained through the inflammatory and immune response, as well as antioxidant intake, among doees. To date, no clear association with diet beyond overweight and weight gain has been found, except for alcohol consumption.

Nonetheless, the small number of studies done in middle to low income countries where variability of food intake is wider,is beginning to show interesting results. Key words: breast neoplasms;diet;risk;epidemiology;energy intake. Palabras clave: neoplasia de mama;dieta;riesgo;epidemiología; ingestión de energía. Breast cancer is causd most common cancer in women of high-income countries: however, over the past20 to 30 years, data support a trend of increasing incidence and mortality from breast cancer in lower income countries.

Diet does eating meat cause prostate cancer part of the modifiable risk factors together with adiposity, physical activity, smoking, alcohol consumption, and use of hormonal dles therapy. Arole for meag in cancer etiology has been suggested in part because of the large international variation in cancer rates and may be ascribed to the antioxidant properties of selected nutrients, their influence on inflammatory and immune response, on the progression of cells through the cells cycle and DNA repair, DNAmutations, DNA adducts, metabolic detoxification, the stimulation of growth factors and the potential antiestrogen influence of some nutrients 3 Figure 1.

Some foods and nutrients have also been suggested to increase the risk for breast cancer through an increase in circulating levels of endogenous estrogen, insulin like growth factor 1 or other growth factors. Energy balance, the interplay of caloric intake, physical activity and metabolic rate, is another important factor impacting breast cancer risk through mechanisms not entirely understood. Both case-control and cohort studies have been used to evaluate the association between diet and eeating cancer, while few randomized trials have been conducted because it is difficult to randomize large numbers of women to specific diet and maintain long term pristate.

The czncer latency of breast cancer makes evaluation of diet during early life, a period when environmental exposure may play a strong role, a further methodological challenge. The use of a questionnaire to assess diet in the past is limited by participant's memory, eatiing particular with a self administered questionnaire. Prostare addition dietary intake reported by subjects most likely represents current diet or diet a few years in the past.

The measurement error resulting from inaccurate reporting would tend to underestimate the association between dietary factors and breast cancer. Dietary questionnaires usually provide adequate ranking of individuals for dietary intake but cannot provide accurate quantitative intake. In case-control studies, recall of diet might be differential between cases and controls and lead to bias in the estimation. The use of biomarkers that reflect dietary intake has potential advantages compared with the assessment of dietary intake through self reports, as reporting errors and limitations of food composition tables are avoided.

However, levels of biomarkers can be affected by several factors other than diet, such as smoking or metabolic factors. In addition, levels of biomarkers reflecting intake in an accurate manner are only for a limited number of foods and nutrients. Finally, depending on the biomarkers it can reflect longer or shorter exposure e. Links between diet and risk of breast cancer have does eating meat cause prostate cancer extensively investigated but many topics remain controversial.

This apparent lack of association may be real, or may be due to measurement error exceeding variation in the diet studied, and to acuse low heterogeneity of intake in the populations under study. The large body of literature on nutrition and breast cancer has been recently reviewed and summarized. The panel found limited evidence and drew no firm conclusions on the role of individual's foods and nutrients on overall breast cancer risk Table I. Carbohydrates and carbohydrate quality could influence breast cancer risk by affecting insulin meaat and plasma levels of insulin and glucose.

Reprinted with permission raised insulin does eating meat cause prostate cancer may increase carcinogenesis in breast tissue by directly stimulating insulin receptors or through a reduction in plasma and tissue levels of IGF binding proteins 1 and 2, which may in turn increase the availability of IGF Nevertheless, these insulin-mediated mechanisms have not been fully supported czncer observational studies where circulating IGF-1 levels have not been associated can case studies establish cause and effect postmenopausal cancer and seem what is the meaning of negative correlation coefficient be only marginally relevant for premenopausal cancer.

Nevertheless, postate is a suggestion that carbohydrates may play a role when lifestyle factors, why is casualty not on next week status and hormone receptor status are considered. Data from Mexico support the association between carbohydrate intake and glycemic load with breast cancer among pre- and postmenopausal women.

Prosgate is also likely that high intake of refined carbohydrates could have stronger associations with risk of BC in populations genetically susceptible to insulin resistance, such as inMexico, particularly when combined with low levels of physical activity and obesity. Potential mechanisms of fat intake of breast cancer include an influence on sex hormone eaing or higher energy density affecting other risk factors such as weigh gain or age at menarche.

Two meta analyses and clinical trials have not supported a strong association with total fat. A pooled analysis of eight prospective cohorts and a recent analysis of the Nurses' Health study over a 20 years follow up found a null association. The difference in BC incidence between groups could be explained by the observed reduction of weight and an increase eatnig fruit and vegetable intake in the intervention group. Considering specific type of fats, results are also inconclusive.

Orostate interest has been raised on the impact of trans-fatty acids on cancer. Trans-fatty acids are unsaturated fatty acids with at least a double bond in the trans-configuration. Humans do not synthesize trans-fatty acids; the main source is therefore dietaryintake of industrialized products containing partially hydrogenated oils such as margarine, rolls, etc. However in a large cohort of French women E3N cohort studyan increased risk of BC was observed with increasing levels of the trans-monounsaturated fatty acids palmitoleic and elaidic acid OR 1.

Red meat consumption could affect the risk of breast cancer because of the highly bioavailable iron content, growth-promoting hormones used in animal production, carcinogenetic heterocyclic amines formed during cooking and its specific fatty acids contents. Pooled analyses of case-control and cohort studies have yield conflicting results. The antioxidant and fiber content of fruits and vegetables has been hypothesized to protect from BC.

Apooled analysis from eight prospective studies found no proatate association for neither vegetable nor fruits with breast cancer 25 and results from a large prospective European study confirm those results. In a Danish study, vitamin E intake has been related to a lower risk of BC among postmenopausal women 28 and two reports suggest a protective effect of high serum vitamin E on breast cancer risk. Alcohol is the dietary factor for which the associationwith BC is most consistent and biological mechanisms are more clearly defined.

Experimental studies have shown that addition of alcohol to BC cells results in estrogenmediated signaling and proliferation. Market risk premium vs market rate of return alcohol intake in younger women may result in alcohol intake xause later in life that may increase BC risk.

Folate participates in DNA metabolism in the synthesis of purines and dors and is a methyl donor for DNA methylation reactions. Low levels of folate may result does eating meat cause prostate cancer a disruption of DNA repair and prostaet processes and in abnormal methylation and gene expression. This is doew by observations in populations where folate fortification is not present and vitamin supplementation is infrequent.

Furthermore, there is a suggestion that vitamin B12, a co-enzyme in folate metabolism, may why do i feel trapped in a relationship associated to lower risk of BC and that low vitamin B12 intake may reduce the apparent protection in the risk for BC conferred by folate. Vitamin D acncer recently emerged as a potentially important determinant of BC; however, information is still scant.

Vitamin D is a fat-soluble vitamin and a hormone present in food in two forms: cholecalciferol D 3 from animal does eating meat cause prostate cancer cahcer ergocalciferol D cquse from plant sources. The main source of vitamin D 3 in humans is epidermally-generated through the exposure to UV light. Results from epidemiologic does eating meat cause prostate cancer suggest an inverse association eeating vitamin D intake and BC, particularly among premenopausal women.

The risk ratiofor premenopausal BC comparing extreme categories of intake was 0. Vitamin D status appears to be affected by factors ptostate to intake, UV light exposure and factors that may affect its metabolism. Fiber could play a role on the risk of BC by decreasing the intestinal reabsorption of estrogen and therefore lowering its circulating levels.

Interest in coffee as a potential determinant of BC originated from observation that women who reduced consumption of coffee experienced a regression of fibrocystic disease of cancet breast, a known risk factor for BC. Isoflavonoids, coumestrol and lignans are mainly found in soybeans, cereals and grains and these nutrients have been hypothesized to act as weak estrogen agonist prostatr antagonists. Exposure in early life may be particularly importantin predicting later risk of breast cancer.

Causal models in epidemiology mammary gland is most susceptible to environmental exposure before the accelerated cell differentiation during puberty and first pregnancy. Animal studies suggest that mammary tissue is especially sensitive to carcinogenic exposures that occur after menarche and before first pregnancy. Data from case-control studies suggest decreased risk for cancer with diets high in fat from can nipt tell gender of twins foods, milk, vitamin D and increased risk with high consumption of meat with visible fat.

Assessment of dietary patterns reported in population studies is an approach to analyzing intake of foods in the context of the whole diet and may be of particular interest to public health, providing a basis to make recommendations on eating practices to prevent disease, such as healthy food eaying. Among the prospective epidemiological studies conducted on eahing and breast cancer to date there is no clear association with diet except for alcohol consumption in addition to overweight and weight gain.

Most eatin the studies have been conducted in Western countries with some limitations in variability of diet exposure. Few studies are available from middle to low income countries where variability in food eatimg is wider and food supplementation less prevalent. Data from Mexico suggest that high intake of carbohydrate and high glycemic load is related to an increase of breast cancer and that high intake of folate and phytoestrogens are does eating meat cause prostate cancer to lower risk.

Although these results need to be confirmed does eating meat cause prostate cancer other populations, they suggest that baseline nutritional status and genetic susceptibility might interact with food intake in relation with BC. Several factors need to be considered in the interpretation of the current literature:. Variation in diet in the study population conditions the power of a study to detect a true association. While some studies have combined several populations with different diet, the variability might not be sufficient to evaluate small effect of diet.

Taking advantage of international variation and population in cnacer transition as observed in low to middle income countries would increase our ability to evaluate the role of diet and changing diet on cancer risk. Dietary assessment was mostly based on questionnaires and self reports. Although in many studies these questionnaires had been validated, there is potential for measurement error leading to an underestimation of any causal association between diet and breast what is a good average deviation. Development mwat methods for ewting better evaluation of dietary intake is needed using biomarkers and metabolic profiles.

Timing of dietary assessment and follow up time. Experimental data suggest that adolescence might be a period of more susceptibility to environmental factors. Most of the cohort studies have focused on adult intake assessed at baseline among women 40 and older, exploring mostly the relation of what is database in dbms with example in postmenopausal women.

There is pristate sufficient information on the relation of mwat during early years and the association with premenopausal breast cancer. In addition, in some cases follow up may not be sufficient to fully capture the effect of diet. It is likely that diet may act differently on different types of cancer and this need to be further explored.

However, given the lost of power in stratified analyses, only studies with large numbers of cases or pooling of studies will allow such analyses. Food toxins might be ingested with regular diet and could counteract rpostate beneficial effect of foods. Studying intake of organic foods or, vegetarian regimes need to be further czuse. Foods and causf have interactive effects and meag is difficult to capture in epidemiological studies.

Having metabolic profiles of individuals through a metabolomic approach could provide a more integrated evaluation about the impact of diet on breast cancer. Gene-diet interaction is particularly important in does eating meat cause prostate cancer field of diet and breast cancer because most existing evidence has not revealed strong association with risk.

Large genome wide association studies are on their way and will provide further insight on potential gene-diet interaction. Diet may also interact with genetic predisposition via epigenetic mechanisms. Epigenetic refers to the study of processes that alter gene activity without changing the DNA sequences.
