When you are pregnant, you may be required to make some changes to your diet. If you are a fan of seaweed, you might wonder 'is it okay to eat seaweed during pregnancy' or can you eat seaweed regularly? There are some types of seaweed that you can safely consume during pregnancy. This article will provide you with this information. 

1. Seaweed and its classification

Seaweed has made its way into the superfood category due to its abundant health benefits. Seaweed is also considered a natural remedy for many ailments. It is commonly used in many Asian dishes in both fresh and dried forms. In addition to its many culinary benefits, seaweed is also rich in nutrients such as vitamins, minerals, proteins, and fiber. Belonging to the algae family, seaweed typically comes in red, brown, and green varieties. The red type is often used to make sushi (nori), the brown type includes many popular varieties such as kelp, wakame, hijiki, and arame, which are often used to make soups and stews due to their chewy texture, and the green type is often used to make salads and soups. Can pregnant women eat seaweed? Most types of seaweed are safe to consume during pregnancy; however, you should talk to your doctor before making any major dietary changes or adding seaweed to your daily diet.

2. The nutritional value of seaweed

The nutritional value of seaweed is calculated based on 10 grams or two tablespoons of fresh Wakame seaweed. Fresh wakame:

  • Carbohydrates: 0.9 grams
  • Proteins: 0.3 grams
  • Vitamin A: 35.0 IU
  • Vitamin C: 0.3 mg
  • Calcium: 14.0 mg
  • Magnesium: 10.5 mg
  • Potassium: 4.9 mg
  • Phosphorus: 8.1 mg
  • Sodium: 85.3 mg

Iodine

Brown seaweed has an extremely high iodine content and can be an important source of this nutrient during pregnancy as long as the expectant mother does not consume too much. The recommended daily intake of iodine during pregnancy is 220 micrograms. Many pregnant women, even those without clear deficiency symptoms, receive less than this amount each day. One gram of seaweed contains between 16 and 2,984 micrograms per serving, with brown seaweed having the highest amount. One serving of brown seaweed per week is considered a safe amount for pregnant women. Because green and red seaweeds have much lower iodine content, you don't need to limit their consumption to once a week as long as you consume them in moderation as part of an overall healthy diet.

4. Health risks associated with eating seaweed during pregnancy

Can pregnant women eat seaweed? Seaweed contains many important nutrients, but it is crucial to limit your intake or consume it in moderation. If seaweed is consumed in excess of the necessary amount, it can lead to potential complications during pregnancy. This may be due to seaweed having a high iodine content, and excessive iodine in the body can interfere with the normal functioning of the thyroid gland. Seaweed can also cause various medical complications during pregnancy and may even harm your fetus. The recommended daily dosage of seaweed is about 220 micrograms, and you should limit yourself to one serving per week. However, this may be true in the case of brown seaweed, but brown seaweed has a higher iodine content compared to green or red seaweed. Therefore, you may not be required to limit your consumption of green or red seaweed to one serving per week. However, you should talk to your doctor before adding seaweed to your diet during pregnancy.
