Relationship between nutrition and reproduction

BACKGROUND: Recently, the relationship between nutrition and reproduction is being studied. In particular, when older women receive reproductive treatment, egg aging causes greater problems than organic factors. METHODS: This study investigated the relationship between nutrition and reproduction with a focus on factors that cause aging, including oxidation, glycation, and chronic inflammation. A large volume of data concerning each nutrient's relationship with reproductive medicine was collected from a number of observational studies. MAIN FINDINGS: The results showed that refined carbohydrates should be avoided and care should be taken to achieve proper intake of omega‐3 fatty acids. Folic acid and vitamin D were also effective. For men, antioxidant measures are especially effective. The effects of antioxidants are related to insulin resistance, which causes chronic inflammation. CONCLUSION: Recent research has shown that rather than meal content, meal intervals are more important for improving insulin resistance. Future research should examine lifestyle‐related nutrition factors and their relationships to reproductive treatment.
