Background: It is important to say that maternal lifestyle during gestation could affect embryonic development and health consequences. Objectives: Many endogenous and exogenous factors affect the epigenetics of the germ cells during their division and subsequently affect the embryogenesis. Methods: This systematic review outline various studies that link the different environmental factors and modification in the fetal epigenome. Conclusion: Aberrant fetal epigenome modification subsequently affects the healthy embryonic growth and their contribution to the phenotypic changes and chronic disease development later in life.

Green coffee bean water extract consumption has been stated to have a contrary association with type 2 diabetes and metabolic syndrome. Chlorogenic acid (CGA), an important biologically active dietary polyphenol, is produced by certain plant species and is a major component of coffee. Reduction in the risk of a variety of diseases following CGA consumption has been mentioned in recent basic and clinical research studies. This systematic review discusses in vivo animal and human studies of the physiological and biochemical effects of CGA on biomarkers of diabetic complication and the possible alterations produced by the administration of different doses of green coffee on biomarkers related to renal, testicular, and neurological antioxidant systems.
