This is one of the reasons we recommend eating lots of whole foods. Insufficient protein intake and insufficient vitamin sources increases your risk of pre-eclampsia. But the good news is you can change!
As I continue on this PE post series, I'm going to jump into talking about individual nutrients, how they function, and the correlation to PE risk. Starting, of course, with Vitamin A....one of the most villainized nutrients in prenatal nutrition.
A 2016 study found that dietary intake of antioxidants was lower in those with preeclampsia, including vitamin A
A meta-analysis from 2022 found enough evidence to support the connection between vitamin A deficiency and preeclampsia.
A study published in 2023 set out to determine whether vitamin E or vitamin A was associated with a decreased risk. Prior to this study, other studies had correlated lower levels of both VA and VE with preeclampsia risk. Few studies had looked into which of the two was associated with the decreased risk. This particular study found a stronger correlation between vitamin A deficiency and the risk of preeclampsia as compared to vitamin E deficiency.
50% of American adults do not consume the current vitamin A recommendations in their diet. According to the WHO, 15% of pregnant women worldwide are truly deficient.
Vitamin A is crucial to the early development of the placenta (as we've discussed, this is where the foundation for preeclampsia starts). Trophoblast cells have receptors for vitamin A.
Add all of this to its need for RBC production, and thyroid function....
