The effect of maternal dietary polyphenol consumption on offspring metabolism.

The early intrauterine environment of mothers during pregnancy significantly affects the metabolic health of their offspring. Existing studies suggest that poor maternal nutrition during pregnancy increases the risk of obesity or diabetes in offspring, so it is highly important to intervene during pregnancy to prevent metabolic disorders in mothers and their offspring. Polyphenols with anti-inflammatory and antioxidant properties are found in many foods and have protective effects on obesity, diabetes, cancer, and cardiovascular disease. Furthermore, recent evidence indicates that maternal dietary polyphenols could be a potential therapy for improving pregnancy outcomes and offspring metabolism. In this review, we discuss the studies and mechanisms of different kinds of maternal dietary polyphenols during pregnancy and lactation in improving the metabolism of offspring, analyze the limitations of the current studies, and propose possible directions of further research, which provide new ideas and directions for reducing metabolic diseases in offspring.
