| Cod Liver Oil Side Effects-high blood pressure? |
In about 5 to 10% of pregnancies, mother develops high blood
pressure (gestational hypertension). Gestational hypertension may
put the health of the mother and infant at risk. At riskier condition
-pre-eclampsia, protein excretion also occurs. [2]
Fish oil or cod liver oil is commonly suggested to pregnant women,
it is beneficial to know what impact that cod liver oil may offer to
the mothers.
In an observational prospective study of 488 pregnant Icelandic
women, researchers estimated the maternal use of cod-liver oil,
foods and other supplements with questionnaires. They found the
odds ratio for developing hypertensive disorders in pregnancy for
women consuming high doses of liquid cod-liver oil was 4.7.
Further, the use of multivitamin supplements without vitamins A
and D in late pregnancy doubled the odds of hypertensive
disorders. [1]
On the other hand, an animal study showed that cod liver oil could
lower blood pressure of Wistar rats. And, its effect on blood
pressure lowering even more pronounced than that of
sunflowerseed oil or partially hydrogenated fish oil!! [3] Probably,
more studies are needed to clarify its effects on our blood
pressure.
