Dietary patterns and breast cancer risk, prognosis, and quality of life: A systematic review

Abstract

BackgroundStatistics indicate that the morbidity of breast cancer is increasing globally, and its (overall figures) incidence has now surpassed that of lung cancer for the first time. The relation between a whole dietary pattern, rather than of a single food or nutrient, and breast cancer (BC) should be examined for findings to capture the complexities of diet and the potential for synergism between dietary components. Hence, the effects of dietary patterns on breast cancer have recently attracted increasing attention.ObjectiveTo systematically review the effects of dietary patterns on breast cancer risk, prognosis, and quality of life in survivors.MethodsThis systematic review was conducted following PRISMA guidelines and was registered in PROSPERO. Data from Ovid, China Biomedical Literature Database, Wanfang Data Knowledge Service Platform, CNKI, PubMed, Weipu, The Cochrane Library, Duxiu Data, ProQuest, Embase, Web of Science, and Scopus Database were retrieved and evaluated.ResultsA total of 47 studies that investigated the association between eating patterns and breast cancer were identified. Ten studies evaluated the effect of the model on treatment outcome and prognosis of breast cancer and two cross-sectional studies examined the influence of dietary patterns on quality of life. The resulting favorable dietary patterns were shown to regulate metabolic biomarkers, antioxidants, anti-inflammatory agents, and protective genes, and inhibit cell proliferation and invasion.ConclusionNumerous studies have examined the effects of healthy eating, plant-based, anti-inflammation, low-fat, and other favorable dietary patterns in relation to breast cancer. However, few studies reported significant associations and the studies had limitations, suggesting that the current findings should be interpreted with caution.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, CRD4202 2350171.

Adherence to Diet Quality Indices and Breast Cancer Risk in the Italian ORDET Cohort

“…Our results of a null association between adherence to the DASH diet and breast cancer risk are not in line with the results of two systematic reviews [36,37], showing how greater adherence to the DASH dietary model was inversely associated with the risk of developing breast cancer [38]. This may be due to the fact that the DASH diet has traditionally been studied for the American population, whose eating habits and dietary survey and assessment tools are different from those used in this study.…”

Male Breast Cancer: Current Scenario and Future Perspectives

“…Several studies have reported that eating more dietary fiber from various sources including whole grains, pulses, vegetables, and fruits can supply essential nutrients and antioxidants that bolster overall health and not only reduce the risk of BC in men but also improve the overall survival (OS) rate. 48 ‐ 51 Incorporation of a diverse array of colors with a wide spectrum of essential nutrients could ensure prevention of BC. 52 Lean proteins sourced from poultry, fish, beans, lentils, and tofu provide essential amino acids necessary for cellular repair and maintenance.…”
