The Association between the Preservative Agents in Foods and the Risk of Breast Cancer.

In the etiology of breast malignancy, dietary habits and lifestyle-related risk factors in the coherence of cancer prevention guidelines, e.g., WCRF/AICR is well documented. In addition, the consumption of staple food products rich in carbohydrate as major calorie resources such as potato, bread, and ready-to-eat cereals are partly object to having roles in breast tumorigenesis. In this review, the possible associations of preservatives and nutritive risk factors of staple foods in dietary patterns with breast cancer development based on the experimental and observational cohort-based studies were discussed. In this regard, the influence kinetics of insulin, insulin-like growth factor-1, and insulin-activated AMPK/Akt pathway on sorts of starch and protein is a concerning biologic concept in promoting the risk of tumorigenesis. Hence, Akt-dependent controlled proliferation, induced apoptosis, and controlled oxidative stress in specific condition could be concentrated as the preventive strategies. Although preservatives such as sorbate, benzoate, and nitrate are considered Generally Recognized as Safe, there are some issues concerning the safety of their applications, including the possibility of allergies and immunosuppressive effects from benzoate, the formation of carcinogenic nitrosamines from nitrites, and interaction sorbate with nitrite in the stomach which consequently can be resulted in the production of a series of genotoxic compounds.
