Brown seaweed provides nutritional benefits and is a good source of iodine, which is necessary for healthy thyroid function, according to Healthline. This salty sea vegetable also provides iron, B-12, folate and riboflavin and can help prevent constipation due to its fiber and magnesium. Because brown seaweed contains these nutrients, consuming it may help boost energy levels, states Healthline.
Brown seaweed may also help fight certain cancers and infections, according to Healthline. Some people believe that brown seaweed can detoxify radiation and provide a miracle cure for cancer, but there is limited scientific evidence to support these claims. However, brown seaweed is a source of fucoidan, which shows potential in eliminating or slowing the advancement of colorectal and breast cancer.
Brown seaweed also contains fucoxanthin, which has been shown to help with weight loss and the reduction of liver fat when combined with pomegranate oil, adds Healthline. However, these nutrients must be taken in the form of supplements to consume a sufficient dose required for these health benefits.
Brown seaweed is an algae that grows in cool ocean waters around the world. It can be eaten raw, cooked or pickled, and is found in many Asian dishes, such as miso soup and salads.
