From the nori used for wrapping sushi and the green variety found in salads to chewy brown seaweed used in soups, read on to find out which types of seaweeds are safe, when and how to eat them, as well as, how much seaweed you can eat safely when pregnant.
Consumption of seaweed is generally considered safe during pregnancy. Even though seaweeds can have many nutritional benefits for pregnant women, some types of seaweed should only be eaten in moderation.
As an aside, certain seaweeds such as hijiki and kombu contain traces of arsenic (source: IJMS) but, again, these are usually not in high enough levels to be of concern during pregnancy, though you may choose to avoid them.
When you become pregnant, many foods are suddenly off limits. Fortunately for seaweed lovers, some types of seaweed are suitable to consume in moderation during pregnancy. In fact, seaweed can provide high levels of nutrients that are essential for fetal development and maternal health.
All forms of seaweed contain high concentrations of nutrients that can help a developing baby grow and thrive. The iron in seaweed is highly bioavailable because of the high vitamin C content also present in these sea vegetables. Vitamin C helps the body absorb and use iron. Seaweed is also a good source of omega-3 fatty acids, which are necessary for fetal brain development. Other nutrients present in seaweed include folate, choline, calcium, vitamin B12 and vitamin K. Seaweed is also a good source of fiber, which can help reduce constipation and improve digestive function during pregnancy.
Brown seaweed is extremely high in iodine, and can be a good source of this important nutrient during pregnancy as long as the pregnant mother does not consume too much. The recommended daily intake of iodine during pregnancy is 220 micrograms, according to the National Institutes of Health Office of Dietary Supplements. Many pregnant women, even those who show no symptoms of an obvious deficiency, get less than this amount. One gram of seaweed contains between 16 and 2,984 micrograms per serving, with brown seaweed containing the highest amounts. One serving of brown seaweed per week is a safe amount for pregnant women, according to Food Standards Australia New Zealand. Because green and red seaweed have much lower levels of iodine, you do not need to limit your consumption of them to once a week as long as you consume them in moderation as part of an overall healthy diet.
Try boosting your intake of wholegrains with some oats for breakfast, a wholegrain sandwich or wrap for lunch, whole grain crackers for a snack and some brown rice and quinoa with dinner. The goal is to reach 48 grams of wholegrains daily, read more about how to reach this on the Grains & Legumes Nutrition Council website.
It's probably fair to say that for lots of people reading this, seaweed isn't a regular staple of their diet. While it's consumed around the world in many coastal cities and particularly in Asian cuisine, many of us wouldn't ordinarily come across seaweed in food except when it's used to wrap up sushi rolls or flavour rice crackers.
Not that these recommendations apply to every species of seaweed. Some species contain large amounts of iodine, and one, hijiki, contains arsenic. The researchers also advise people to never eat any seaweed that washes up on the shore. But for the right variants, when procured safely, a small amount daily could be a flavoursome boost to a healthy diet.

In recent years, seaweed has emerged as a superfood and has gained importance as a dietary supplement. But, you may not be sure of the safety of seaweed during pregnancy. Pregnant women should exercise caution while consuming it because it can have adverse effects on the growth of the fetus if taken in excess.
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 best to stick to minimal consumption of seaweed during pregnancy, if at all. Also, rather than taking supplements and buying risk to your health, you can get minimal necessary iodine from seaweed consumption.
Seaweed is a good source of antioxidants, vitamin C, omega-3 fatty acids, and fiber. You may consider eating seaweed during pregnancy due to its nutritional value and beneficial effects on digestion and fetal brain development. However, due to its high iodine content and potential adverse effects on the thyroid gland, moderation is advisable to consume seaweed. But, one cannot rule out heavy metal contamination in seaweed, so it is best to include it in your pregnancy diet after consulting a doctor or a nutritionist.
Seaweeds are a great source of nutrients essential for the mother and the growing baby when consumed in moderation. In this infographic, we shed light on the most common types of edible seaweeds and the various benefits they offer.
Fresh seaweed from the ocean is definitely dangerous for dogs. If your dog finds dried seaweed on the beach, do not let them eat it. Wild seaweed shrinks in the sun but when your dog eats it, it expands in the digestive system, which could cause fatal blockages.
Good nutrition during pregnancy can help to keep you and your developing baby healthy. Your need for certain nutrients (such as iron, iodine and folate) increases when you are pregnant. A varied diet that includes the right amount of healthy foods from the 5 food groups generally provides our bodies with the vitamins and minerals it needs each day. However, pregnant women may need to take vitamin or mineral supplements during pregnancy (such as folate and vitamin D).
Folate (known as folic acid when added to foods) is a B-group vitamin found in a variety of foods. Folic acid helps protect against neural tube defects in the developing foetus. It is important for pregnant women to make sure they are receiving enough of this important vitamin. For women who are planning a pregnancy, and during the first 3 months of pregnancy, a daily folic acid supplement of 500 micrograms is recommended, as well as eating foods that are naturally rich in folate or are fortified with folic acid.
Overall, there is lack of data regarding seaweed availability and consumption in the British diet, with limited consumer knowledge on the product(s) . There is potential for seaweed to act as a functional food and ingredient , relative to its role as a rich source of iodine , its antimicrobial properties against mainly Gram negative microorganisms  and satiating properties when included in food products such as beverages, breakfast bars and pizza [11,12], and use in low sodium salts. The role of seaweed as a rich source of iodine is particularly relevant in the UK, where recent surveys have highlighted insufficiency in different groups of the population [13,14,15,16], with iodine being an essential component of thyroid hormones, which are essential for neurodevelopment in utero and after birth [17,18].
The main dietary sources of iodine in the UK are dairy products, mainly milk, and seafood. However, fish consumption is low in the British population and milk consumption is decreasing . In 2007, 130 countries and almost 70% of the world population were using iodised salt , according to WHO recommendations for universal salt iodisation . However, in the UK, there is no prophylaxis, the availability of iodine rich salt in the market is very low , compounded by low awareness about iodine importance in pregnancy and poor knowledge of iodine-rich foods . Recent coverage in the UK media also advocated for a seaweed-based diet, in response to low iodine intake in the population, which is potentially harmful, since it may lead to over-exposure to the nutrient .
Exposure to excess iodine can lead to formation of a goiter, hypothyroidism or hyperthyroidism and iodism in case of chronic exposure. Large (excessive) iodine intake can inhibit the formation of thyroid hormones and increase plasma TSH, a phenomenon known as the Wolff-Chaikoff effect, which is transient. In vulnerable groups with autoimmune thyroid disease, excessive iodine intake can also lead to thyroiditis, sensitivity reactions, and papillary thyroid cancer [10,40,41]. There was however no direct association between seaweed consumption and thyroid cancer when healthy Japanese women were studied . The present study identified a range of products (n = 26) which could provide higher iodine intake than the TUL of 600 μg/ day , raising the concern of the safety of these products consumption in a regular basis. 2b1af7f3a8
