From the Guidelines

Consuming seaweed sheets may help reduce inflammation in the body due to their rich content of anti-inflammatory compounds, including omega-3 fatty acids, which have been shown to reduce inflammation and improve cardiovascular health 1. The potential anti-inflammatory effects of seaweed sheets are attributed to their unique bioactive substances, including fucoidan, fucoxanthin, and various polyphenols, which have demonstrated anti-inflammatory properties in scientific studies. Some key points to consider when consuming seaweed sheets for their potential anti-inflammatory benefits include:

  • Seaweeds are good sources of omega-3 fatty acids, which are well-known for their anti-inflammatory effects 1.
  • A Mediterranean-style diet, which includes foods with antioxidant and anti-inflammatory properties, has been shown to lower the risk of developing rheumatoid arthritis, a condition characterized by joint pain and inflammation 1.
  • Consuming about 5-10 grams (typically 1-2 sheets) of nori, wakame, or kombu seaweed several times per week as part of a balanced diet may provide potential anti-inflammatory benefits. However, it is essential to note that seaweed should be viewed as a complementary approach rather than a primary treatment for inflammatory conditions. Additionally, people with thyroid disorders should consume seaweed in moderation due to its high iodine content, and those on blood-thinning medications should consult their healthcare provider as seaweed may enhance the effects of these medications. Overall, incorporating seaweed sheets into a balanced diet may be a useful adjunct to other anti-inflammatory strategies, but it is crucial to prioritize a comprehensive approach to managing inflammation and overall health.

From the Research

Seaweed Sheets and Inflammation

  • Seaweed sheets, commonly used in sushi, are a rich source of omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) 2, 3.
  • These fatty acids have been shown to have anti-inflammatory properties, which can help reduce inflammation in the body 2, 3, 4, 5, 6.
  • The anti-inflammatory effects of omega-3 fatty acids are thought to be due to their ability to inhibit the production of pro-inflammatory cytokines and eicosanoids, as well as their ability to promote the production of anti-inflammatory mediators 2, 3.

Benefits of Omega-3 Fatty Acids

  • Omega-3 fatty acids have been shown to have numerous health benefits, including reducing the risk of chronic diseases such as cardiovascular disease, cancer, and autoimmune disorders 3, 6.
  • They have also been shown to improve symptoms of rheumatoid arthritis, systemic lupus erythematosus, and multiple sclerosis 3.
  • Additionally, omega-3 fatty acids have been found to have anti-aging effects, improving cognitive function, and reducing the risk of age-related diseases such as Alzheimer's and Parkinson's 3, 5.

Seaweed Sheets as a Source of Omega-3 Fatty Acids

  • While seaweed sheets are a rich source of omega-3 fatty acids, it is essential to note that the amount of omega-3s in seaweed sheets can vary depending on the type of seaweed and the processing methods used.
  • However, consuming seaweed sheets as part of a balanced diet may help support overall health and reduce inflammation in the body 2, 3, 4, 5, 6.
