What are the benefits and drawbacks of eating raw seaweed

Eating raw seaweed can retain more water-soluble vitamins and minerals, but it may cause gastrointestinal discomfort or a risk of parasitic infections. Seaweed is rich in minerals such as iodine, calcium, iron, and vitamin B12, which are not easily lost when eaten raw. Some people may experience bloating and diarrhea when eating raw seaweed, and marine pollutants may be ingested through raw food. Seaweed, as a type of seaweed food, can retain heat sensitive components such as vitamin B and vitamin C intact without heating treatment. Among them, phycobiliproteins and polysaccharide active substances have certain help in regulating immunity. Raw seaweed has a crispy and tender texture, which can stimulate saliva secretion during chewing and aid in the early stages of digestion. In traditional consumption methods in coastal areas, fresh seaweed is often cold mixed or used as soup ingredients, but it is necessary to ensure that the raw materials come from clean waters.

Seaweed surface may adhere to marine pathogenic bacteria such as Vibrio parahaemolyticus, and there is a risk of infectious diarrhea when eaten raw. Industrialized cultivated seaweed may have residual heavy metals, and long-term consumption can increase the probability of toxin accumulation. Individuals with thyroid dysfunction should be alert to the impact of high concentrations of iodine in raw seaweed on hormone secretion. Some individuals with sensitive constitutions may experience allergic reactions such as skin itching after consumption, which are related to the phycocyanin in seaweed.

It is recommended to choose dried seaweed with organic certification and soak it in diluted salt water before consumption. Daily intake should be controlled within 5 grams of dry weight, combined with citrus fruits rich in vitamin C to promote iron absorption. Special groups such as pregnant women, children and people with weak digestive function should avoid eating raw food. Heating methods such as laver Egg&vegetable soup can ensure safety and nutrition. When persistent abdominal pain or rash occurs, immediately stop eating and seek medical attention.
