Dulse (palmaria palmata), a protein-rich red seaweed, could become a new protein source to compete with current protein crops like soybeans, according to scientists at Ireland’s Teagasc Food Research Centre. Dulse harvested from October to January usually has the highest protein content.
This functional food also contributes levels of essential amino acids such as leucine, valine and methionine, similar to those contained in legumes like peas or beans. It may even help protect against cardiovascular disease. The agriculture and food development authority reports that for the first time, researchers have identified a renin-inhibitory peptide in dulse that helps to reduce high blood pressure, like ACE-1 inhibitors commonly used in therapy.
