Dulse (aka. Red Seaweed; Palmaria palmata) is a red algae that grows in the northern hemisphere on coasts of the Atlantic and Pacific Oceans.
Dulse attaches itself to rocks or other seabed features by its holdfast (as opposed to roots used by true plants).
It develops fronds that are variable but like flat leathery blades which expand upward almost 2 feet with divided segments.
Dulse has been consumed as a food or snack in many cultures for thousands of years, and in some cultures is an important part of their cuisine. In Iceland it is an important dietary fiber source. It has also been used as a fodder for animals.
Dulse is rich in certain vitamins, and contains Omega-3 and Omega-6 fatty acids, fiber, protein, as well as is packed with minerals and trace minerals.
It is a good source of iodine, which is needed in the diet.
Dulse can be consumed fresh, but it is often sun dried and sometimes processed into smaller cuts, powders or flakes.
Dulse is used in many dishes, for example, in Iceland it is fried into chips and served with cheese, and in Ireland it is used to make white soda bread.
It is also useful in recipes as a flavor enhancer, adding a umami taste to dishes. There is even a strain of Dulse that is reported to taste like bacon! The extract of Dulse is considered GRAS in the US.
Dulse also has a long history of use as a traditional medicine in several cultures—especially as a medicinal food.
It is used for promoting healthy bones (by supplying minerals needed for the bone matrix), for thyroid health due to its content of iodine, for digestion (due to the fiber), vision (vitamin A), cardiovascular health and the immune system.
Dulse is also thought to have soothing and nourishing properties when applied topically to skin.
In exciting new research, mycosporine-like amino acids have been found to show potential for photoprotection and use in natural sunscreens and anti-aging formulas.
Through scientific investigation, Dulse has exhibited activities such as antioxidant, anti-inflammatory, and inhibition of neutrophil activation.
