It was nice to see some research done on the effects of a fathers diet on conception. This was a rat study looking at folic acid levels in fathers and birth defect rates in offspring. The less folic acid in the father’s diets, the more birth defects. Paternal diet and health is very important in conception and health of children. I will caution as always however not to supplement with high levels of folic acid unless you know your genetic MTHFR status. Folic acid may be dangerous for some people with certain differences in this gene. A simple blood test can tell you if folic acid is safe for you or if you need a pre-methylated form of the vitamin to improve you detoxification processes, and prevent many common diseases like Alzheimer’s, diabetes, and depression.
