Seaweed is an excellent source of iodine, a vital trace mineral that plays a critical role in thyroid health. The body doesn’t make iodine on its own, so you need to get it from food sources or supplements.
The health benefits of seaweed include:
1- Improves thyroid function.
Your thyroid plays a crucial role in your overall health, and iodine plays a vital role in its ability to function properly. Insufficient iodine means that your thyroid can’t make enough thyroid hormone (a condition known as hypothyroidism), which regulates many bodily functions, including metabolism. If you don’t get enough iodine, you may develop a goiter, a visible enlargement of your thyroid. Iodine deficiency can also impact children during development, both in the womb and during early childhood
2- Improves gut health
Seaweed has carrageenans, agars, fucoidans, which act as prebiotics, non-digestible fibers that feed the healthy bacteria in your digestive tract. Sulfated polysaccharides (sugars found in seaweed) help to increase the growth of the good bacteria and increase the short-term fatty acids that keep the lining of your gut healthy.
3- Improves heart health.
Some studies show that seaweed intake may help to reduce blood pressure. It may also help to reduce LDL cholesterol and total cholesterol levels. Results of human studies are promising, but more research is needed.
4- Stabilizes blood sugar levels.
Brown seaweed contains fucoxanthin, an antioxidant that gives the vegetable its color. The antioxidant may play a role in helping to improve blood sugar control and reducing your risk of developing type 2 diabetes.
5- May boost your immune health.
Some studies show that seaweed may help to boost your immune system by fighting viruses and preventing them from getting into your system. More studies are needed, however.
6- May reduce cancer risk.
Adding seaweed to your diet may help to reduce your risk of developing certain types of cancer. It may decrease estrogen levels, which may reduce the risk of breast cancer. Again, there are very few human studies available, so more research is necessary.
