Can Pregnant Women Eat Seaweed?
With its tempting health benefits, seaweed may sound like an ideal food to be consumed during pregnancy, considering the amount of nutrients that it has to offer. However, it is best to limit its consumption during pregnancy, and have a talk with your healthcare provider regarding the ideal dosage to be followed for the same.
According to the Food Standards Australia New Zealand, pregnant women must limit their consumption of seaweed to not more than one serving per week. This is because seaweed tends to contain unnaturally high amounts of iodine, which could be potentially dangerous if consumed during pregnancy.
Iodine is an important nutrient that the body needs to function properly, but if taken in excess, it could have a negative impact on the functioning of the thyroid gland. It has been found that pregnant women who consumed excess of seaweed during pregnancy had babies that were ill.
It is therefore best to stick to moderate consumption of seaweed in pregnancy, so that the excess iodine can be rapidly excreted from the body. (2)
And yes, seaweed, when consumed in the right amount, could actually be helpful during pregnancy. Thanks to its high iodine content, seaweed could prove to be extremely helpful in preventing neurological impairment in the developing baby, and could positively affect the baby’s reading ability later in life. (3)
Infact, a study conducted on Japanese women has revealed that the consumption of seaweed when pregnant could reduce the risk of depressive symptoms in women to a considerable extent. (4)
Possible Health Risks Associated With Seaweed
Seaweed is a small sized package of many nutrients, some of them in quantities that exceed our daily recommended intake. This is why, consumption of seaweed on a regular basis could prove to be harmful, particularly for pregnant women.
According to Medline Plus, seaweed, owing to its high concentration of iodine, could be harmful for pregnant women. (5)
Seaweed is often used as a supplement and is believed to improve breast milk supply in lactating women, but daily intake could cause abnormally high levels of iodine in the body, which may in turn, affect the thyroid gland of both the mother and the baby, possibly even causing hypothyroidism in newborn babies. (6)
What’s more, a study has also pointed out to a strong association between the consumption of seaweed and a risk of thyroid cancer in women. (7)
