Fathers 'need to think about diet just as much as mothers'
Sarah Kimmins says their findings suggest that fathers need to think about what they eat, smoke and drink just as much as mothers do, as their lifestyle choices could impact future generations.
And she notes that although folate is added to many foods, fathers who have diets that are high in fat or who are obese may be unable to metabolize folate in the same way as those who have sufficient levels of the vitamin.
"People who live in the Canadian North or in other parts of the world where there is food insecurity may also be particularly at risk for folate deficiency. And we now know that this information will be passed on from the father to the embryo with consequences that may be quite serious."
The researchers say that the next steps from this research will be to collaborate with professionals at a fertility clinic in order to further investigate how a man's diet and weight could impact their child's health. Last year, Medical News Today reported on a study suggesting that a father's occupation may be linked to the risk of birth defects in their infants.

Yes, research suggests that paternal diet quality—particularly regarding folate intake and obesity—can impact fetal development and potentially increase the risk of birth defects. A father's lifestyle choices, including diet, smoking, and alcohol consumption, may influence genetic expression that is passed to the embryo, with potentially serious health consequences for the child.
What role does folate play in male fertility and fetal health?
Folate is essential for proper DNA synthesis and methylation, processes that are critical for healthy fetal development. Men with obesity or high-fat diets may have difficulty metabolizing folate effectively, even when the vitamin is added to foods, which can impact embryonic health and increase birth defect risk.
How does paternal obesity affect pregnancy outcomes?
Paternal obesity may impair folate metabolism and nutrient absorption, which can negatively impact sperm health and embryonic development. Research indicates that overweight or obese fathers may pass on metabolic vulnerabilities to their children that affect long-term health outcomes.
Should men take prenatal vitamins or folate supplements before trying to conceive?
While the American Society for Reproductive Medicine (ASRM) emphasizes the importance of male preconception health, specific supplement recommendations should be discussed with your fertility specialist or primary care physician. Generally, men can meet folate needs through a balanced diet rich in leafy greens, legumes, and fortified grains, though supplementation may be beneficial for those at risk of deficiency.
What paternal lifestyle factors should I address before conception?
The FDA and fertility experts recommend that men optimize their health before conception by maintaining a healthy weight, eating a nutrient-rich diet, avoiding smoking and excessive alcohol, and managing stress. These preconception lifestyle changes can improve sperm quality and potentially reduce the risk of birth defects and long-term health issues in offspring.
Are there specific dietary guidelines for men planning to father children?
While formal paternal preconception nutrition guidelines are still emerging, experts recommend a diet rich in antioxidants, vitamins (especially folate, B12, and vitamin C), minerals, and lean proteins to support sperm health. Men should focus on whole foods, limit processed foods high in saturated fats, and maintain a healthy BMI, as these factors directly influence reproductive health.
Does health insurance cover male fertility evaluations or preconception counseling?
Coverage varies significantly by insurance plan and state; some plans cover fertility evaluations while others do not unless infertility is already diagnosed. Contact your health insurance provider directly or consult with an American fertility clinic, as they can often help navigate insurance coverage options for male preconception health assessments.
