Seaweed intake and risk of cardiovascular disease: the Japan Public Health Center-based Prospective (JPHC) Study.

Following a high seaweed diet may diminish the risk of developing cardiovascular diseases, including ischemic heart disease.

​This study assessed the consumption of seaweed in relation to the occurrence of stroke and cardiovascular disease. With the aid of validated food frequency questionnaires, researchers collected and analyzed data on the seaweed intake levels of over 90,000 Japanese men and women. The relative risk of developing cardiovascular disease and stroke was ascertained in all the participants in this study. 

Researchers noted that regular ingestion of seaweeds brightened an individual's chances of evading cardiovascular diseases, including ischemic heart disease. However, frequent consumption of seaweeds was found to have no significant effect on stroke risk in this study. Evidence from this study support the inclusion of seaweeds in a heart healthy diet.
