What are the benefits and drawbacks of seaweed

Seaweed is rich in various nutrients, and moderate consumption can help supplement iodine, dietary fiber, and vitamins. However, excessive intake may cause excessive iodine intake or gastrointestinal discomfort.

1. Effect

Seaweed is rich in iodine, which helps maintain normal thyroid function and prevent thyroid enlargement. The dietary fiber in seaweed can promote gastrointestinal peristalsis, aid digestion, and prevent constipation. Seaweed also contains various vitamins, such as vitamin A, vitamin B family, and vitamin C, which help enhance immunity and improve skin health. Seaweed has a high protein content and contains various essential amino acids, making it suitable as a source of plant protein. The polysaccharides in seaweed have a certain antioxidant effect, which helps to delay aging.

II. Disadvantages

Seaweed has a high iodine content, and long-term excessive consumption may lead to excessive iodine intake, causing thyroid dysfunction. Some people may have allergic reactions to the algal protein in seaweed, resulting in skin itching or digestive problems. Seaweed has a high purine content, and gout patients should control their consumption to avoid worsening symptoms. Seaweed may have residual marine pollutants on its surface, and long-term ingestion in large quantities may pose potential health risks. Seaweed has a harder texture and weaker gastrointestinal function. Consuming it in large quantities may cause bloating or discomfort.

It is recommended to consume seaweed 2-3 times a week, with no more than 10 grams of dry weight per time. Thyroid disease patients should adjust their intake of seaweed under the guidance of a doctor. When choosing seaweed, attention should be paid to whether the product has passed safety testing and avoid purchasing products from unknown sources. Seaweed can be used in various cooking methods such as soup, vegetable mixing, or rice wrapping, and can be paired with other ingredients to balance nutrition. If discomfort occurs after consumption, it should be stopped promptly and a doctor's opinion should be consulted.
