The New Nutritional Trend with High Nutritional Value but also Potential Risks

Seaweed, a nutritional trend gaining traction, offers a wealth of nutrients and health benefits, but also carries potential risks. Traditionally consumed in Asian countries like Japan and Korea, but also in Ireland and Iceland, seaweed is rich in minerals, vitamins, fiber, and essential fatty acids, such as omega-3s. The nutritional profile of seaweed varies depending on the type, but generally it is low in fat and calories. Nori is rich in protein, kelp in iodine, sea lettuce in iron, and wakame in calcium. They also contain fiber that aids digestion and vitamins A, B, C, D, E, and K. Fucoidan, a fiber found in seaweed, has been shown to boost the immune system, reduce inflammation, and lower blood pressure. However, due to the high iodine content, seaweed should be consumed with caution by individuals with thyroid problems or those taking medication. It is recommended to consume seaweed from all three groups (green, red, and brown) to maximize benefits. However, excessive consumption can cause health problems, so moderation and expert advice are important.
