Benefits of eating dulse (red algae) and how much you should consume daily
This seaweed is a great sea vegetable with nutritional value that is better from some land-based plants. Dulse is a great food choice if you care about your health and want to follow a healthy diet.
If you are not familiar with the health benefits of dulse, how much should you eat per day or you want to learn how to prepare it this healthy seaweed, you are at the right place.
We’ve covered all these topics in this article. First, let’s see what is dulse and where it comes from? Is this new or food used for centuries?
What Is Dulse?
Dulse (Palmaria Palmata) is a red algae with leathery fronds (leaves) that grows along the northern coastlines of the Pacific and Atlantic oceans. It is collected by hand by the harvesters plucking it from the rocks at low tide.
The good thing about this red algae is that it is perrenial and when is cut or plucked, new growth appears from the previous season’s leaf.
This sea vegetable Europeans have been eating for more than 1.500 years. It is harvested mainly in Ireland and the shores of the Bay of Fundu in eastern Canada. After picking the seaweed is laid out to the sun to dry for 6-8 hours. If that is not possible, can be stored in seawater for a few days, but it soon deteriorates.
Today we know that dulse is rich with vitamins, minerals, antioxidants, protein, and fiber. It is eaten worldwide, packed for sale in plastic bags, 50 g per bag, broken into flakes or ground into powder for use as seasoning. Dried dulse is often served as a snack in bars (for free) because it induces thirst.
Extremely rich in iodine
One of the major health benefits of dulse is that can play an important role in proper thyroid function.
Dulse seaweed is an iodine-rich sea vegetable with a 30 g serving to provide 110% of the RDI for this compound. Iodine is an essential mineral for the thyroid and it is crucial for the proper function of the thyroid gland. Iodine is so important for the thyroid that is called ” food for the thyroid”.
Iodine also displaces dangerous “halides” such as bromide, chlorine, and fluorine in the thyroid. Except for the thyroid function, iodine also is an antioxidant, protects from radiation, and kills bacteria and fungi.
You should know that if you eat too much dulse you can upset the balance of hormones in your thyroid. So, eat dulse in moderation. People with hypo or hyperthyroidism should probably avoid eating dulse.
Rich source of vitamins
Only 7 gram serving of Dulse seaweed provides around 40% of vitamin A. Vitamin A acts as an antioxidant and prevents free radicals from damaging the tissues of the eye and causing macular degeneration. In Dulse, it is in the form of beta carotene. Vitamin A is also a component of rhodopsin, a protein in the eye that boosts vision in low light conditions.
Eating Dulse is an excellent way for vegans or people who don’t eat animal foods to get sufficient vitamin B-12. A 3.5-ounce portion of fresh dulse contains 6.6 micrograms of vitamin B-12, which is more than 100 percent of the daily value set by the FDA.
This vitamin assists in making new cells and breaking down some fatty acids and amino acids. Also protects nerve cells and encourages their normal growth. Vitamin B-12 deficiency can cause memory loss, dementia, and numbness in the arms and legs. That’s why Dulse is such good food especially for those who are on a vegan or vegetarian diet.
Vitamin C helps our immune system to be stronger. Among many other functions act as antioxidants, neutralizing unstable molecules that can damage cells. Helps with collagen production and white blood cell count.
The superfood dulse contains large amount of dietary fiber. In a 2 ounce of serving you get 16 grams of fiber.
This soluble fiber absorbs water in the digestive system to form a gel-like substance. It helps to soften the stool and bind the substances like cholesterol and sugar, thus preventing or slowing their absorption into the blood.
Seaweed fibers are different from those found in land-based foods. They contain alginic acid also called alginate (polysaccharide substance) which helps to detoxify heavy metals and radioactive isotopes from the body.
Polysaccharides from the seaweed help with liver detoxification and this cleansing action they provide help with healthy-looking skin.
By using dulse in your daily diet you will maintain a healthy bowel movement or digestive process with fiber. This will result in lowering the risk of overweight or suffering from obesity.
Healthier nervous system
If we mention that dulse is rich with polyunsaturated fatty acids, you will probably ask what are they. But if we say that these algae are rich with omega-3 and omega-6 fatty acids, you will know what we are talking about.
These fatty acids are important for our health because they play a major role in the proper function of the nervous system and brain. They also help regulate blood clotting and blood pressure.
The National Institute of Health (NIH) has reported the majority of U.S. diets don’t contain the amount of omega-3 fatty acids needed for overall health and wellness. A healthy diet should consist of roughly two to four times more omega-6 than omega-3 fatty acids. Typical North American diet consists of 11 to 30 times more omega-6 than omega-3 fatty acids, and the result is the rising rate of inflammatory disorders in the U.S.
Opposite of this, the ratio between omega-6 and omega-3 fatty acids in dulse is close to one, which is believed to be optimal.
Packed with valuable minerals
In this list of health benefits of dulse seaweed, we must mention that these red algae are rich in minerals that our body needs for everyday function. A single serving of dulse provides us with magnesium, calcium, potassium, iron, and chromium.
Minerals like calcium and magnesium are essential for strong bones and healthy teeth. Almost half of the body magnesium is stored in the bones where it acts as a cofactor with calcium and vitamin D and strengthens the bone structure and teeth. Important to know for teeth is that teeth can form hard enamel from calcium if magnesium is present.
Because our bodies don’t produce iron it is crucial to include a sufficient amount of iron through our healthy diet. Dulse is a great choice to do that. Iron helps to form and oxygenate our blood cells and hemoglobin. Contributes to normal cognitive function converts food to energy, helps maintain a normal nervous system.
Potassium helps your heart maintain a steady beat and is needed for proper muscle contraction and it is vital for synthesizing proteins and metabolizing carbohydrates.
Healthy tip: Pay attention to the potassium content of salt substitutes, it can be high. High blood potassium levels are dangerous.
If you are a vegetarian dulse is a great substitute for meat to get all the proteins that your body needs for normal function. A 3.5 ounce serving of fresh dulse gives you 21.5 g of protein. According to FDA 21 g is 43% of the daily requirement for protein.
Dulse contains more protein than other seaweeds like konbu (7%), wakame (13%), and winged kelp (18%), but much less than nori (45%).
If we mention that proteins not only help with the creation of new cells, they play a vital role in the repair and maintenance of your body. This is just another thing that shows why eating dulse is beneficial for your health.
How Much Dulse Should I Eat Daily?
A safe recommendation based on the traditional consumption of seaweeds in Japan would amount to a daily intake of 5 g dry weight, corresponding to 30-50 g wet weight depending on the species. Because different seaweeds have different nutritional value another safe recommendation would be to compose these 5 g of dry seaweed, at least averaged over the week by different species. Dulse could be one of them.
Depending on methods of preparation such as soaking, boiling, heating, marinating, the amounts of various compounds in seaweed material, and the medium were are preparing can vary substantially. For example, iodine can seep out during soaking and fatty acids can oxidize during heating treatment.
Scientists from the Danish Veterinary and Food Administration have cautioned that dulse may contain dangerous levels of the neurotoxin kainic acid, which when consumed in large doses may cause brain damage. But research from professor Ole G. Mouritsen from the University of South Denmark shows that dulse contains only small doses of kainic acid.
A person needs to eat 150 kg of fresh dulse in one go to experience the poisoning effect observed in animal studies. “Dulse is – when you observe common-sense rules for freshness and hygiene when handling food – perfectly safe to eat. No person can eat 150 kg in one go” – says Professor Mouritsen.
Important: People with an iodine allergy should not consume seaweed. Also, people who take any medications in case of thyroid disorder should consult with their doctor before consuming dulse seaweed.
