“…The analysis of the FFQ shows that women with breast cancer reported a lower daily consumption of red meat, although the difference was not statistically significant. This finding is not consistent with other studies in the literature which found high consumption of red meat as associated with a higher risk of breast cancer, possibly due to the high content of saturated fat in this food [9,42,43]. In Brazil, other case-control studies have found a significant association between high consumption of red meat and breast cancer [44,45].…”

“…Dietary and lifestyle factors may have an important role in the development of breast cancer (2)(3)(4) , among which Ca intake has been suggested as a potential protective factor in mounting experimental research (5)(6)(7)(8)(9)(10) and several observational studies (11)(12)(13) . A metaanalysis by Chen et al (14) involving six prospective cohorts and nine case-control studies suggested a significant inverse association between Ca intake and risk of breast cancer, with a summary relative risk (RR) of 0·81 (95 % CI 0·72, 0·90) for the highest compared with the lowest intake of Ca, with a significant publication bias.…”

Calcium intake and breast cancer risk: meta-analysis of prospective cohort studies

Findings from observational studies have suggested a possible relation between Ca and breast cancer risk. However, the results of these studies are inconclusive, and the dose-response relationship between Ca intake and risk of breast cancer remains to be determined. A meta-analysis of prospective studies was conducted to address these issues. PubMed and Embase databases were searched for relevant studies concerning the association between Ca intake and breast cancer up to March 2016. The summary relative risks (RR) with 95 % CI were calculated with a random-effects model. The final analysis included eleven prospective cohort studies involving 26 606 cases and 872 895 participants. The overall RR of breast cancer for high v. low intake of Ca was 0·92 (95 % CI 0·85, 0·99), with moderate heterogeneity (P = 0·026, I 2 = 44·2 %). In the subgroup analysis, the inverse association appeared stronger for premenopausal breast cancer (RR 0·75; 95 % CI 0·59, 0·96) than for postmenopausal breast cancer (RR 0·94; 95 % CI 0·87, 1·01). Dose-response analysis revealed that each 300 mg/d increase in Ca intake was associated with 2 % (RR 0·98; 95 % CI 0·96, 0·99), 8 % (RR 0·92; 95 % CI 0·87, 0·98) and 2 % (RR 0·98; 95 % CI 0·97, 0·99) reduction in the risk of total, premenopausal and postmenopausal breast cancer, respectively. Our findings suggest an inverse dose-response association between Ca intake and risk of breast cancer.

“…Vegetables and their products were not taken as meals by cohort of subjects and controls, but rather as parts of meals in which carbohydrates is a predominant portion. Although, vegetables have been shown to be associated with lower risk of breast cancer by providing high-fibre diets, low in energy and fat (Chang et al, 2017;Catsburg et al, 2015;Mourouti et al, 2015;Lelièvre and Weaver, 2013), there is no consensus about their ultimate value nevertheless studies have found the consumption of soy products associated with a lower risk for breast cancer (Wu et al, 1998;Greenwald, 2002). Aside from this, there is also no consensus as regard to their value when it comes to breast cancer risk.…”

The aetiopathogenesis of cancer has been linked to life behaviour in a significant percentage of cases. Overweight, sedentary lifestyle, smoking and the excessive use of alcohol have been shown to play important roles. This study is aimed at determining the effect of life behavioural patterns and diets in the incidence of breast cancer in Nigerians population. A prospective case-controlled study of 125 breast cancer patients and 89 normal were recruited in Obafemi Awolowo University Teaching Hospital Complex, (OAUTHC), Ile-Ife, Nigeria. Questionnaire was administered to determine life behavioural patterns and nutritional habits. The variables on nutrition items were pooled to form 23 aggregate variables renamed "total variables" and exposure to endogenous estrogens was calculated. The means age in the patient and control groups were 45.9±10.4 and 44.5±15.2 years, respectively. A significantly higher number of patients in the breast cancer group had at least one previous abortion compared to the control group. The two groups have similar contraceptive use history and mean body mass index (BMI). 14 derived variables on univariate analysis were found to be significant, but only four (menarche [p = 0.002], "total beans" [p = 0.003], "total oils" [p = 0.021] and alcohol intake [p = 0.034]) reached statistical significance when subjected to multivariate regression analysis. Most were premenopausal but onsets of menarche were significantly higher among breast cancer patients. The onset of menarche, intake of beans, oils and alcohol may play a role in the incidence of breast cancer.

Abstract: Adherence to a plant-based diet that limits red meat intake may be associated with reduced risk of breast cancer, particularly in postmenopausal women.
