Nutrition and the placenta.
PLACENTAL HEALTH /// This temporary organ is one of the least understood miracles of pregnancy. The nutrients your baby receives, stress signals, thyroid hormone levels, and even the (pre-birth) transfer of microbes is dependent upon the placenta.
In my weekly research time, I came across a really interesting review article that explores the current (albeit limited) data on the placenta and how it may play a role in fetal brain development.
I can’t say the article had any directive takeaways that I can pass on to you (like” you need x amount of this nutrient to ensure x”—research is very rarely that clear), but it did help me appreciate just how crucial the placenta is to positive pregnancy outcomes.
From the article: “The placenta is not only a passive supplier of nutrients for the fetal brain but an active brain architect too; by the integration nutrient and prenatal stress signals into chromatin changes at specific gestational time windows; the placenta becomes involved in the structural designs and functional inter-neuronal connections of the developing brain, which may possibly determine the personality and the health status of the fetus and future adult.”
So far our understanding of the placenta is that its function is, at least to some degree, influenced by maternal nutrition. Genetic expression can shift in the placenta in response to poor nutrition (like calorie or protein restriction), which then affects the nutrient transfer/metabolic signals to baby and ultimately impacts brain development.
