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 drug therapy.
