Human Health Benefits of Dulse (Palmaria palmata)

Some of the most important human health benefits of dulse include its ability to improve vision, protect the immune system, build bone health, improve the thyroid gland, increase growth and repair, optimize the gastrointestinal system, lower blood pressure, strengthen the brain and nervous system, and boost circulation.

This nutrient-rich form of red alga has been an important food source for more than a thousand years in various parts of the world. It primarily grows on the northern coasts of the world’s major oceans, and is readily available in many areas. Dulse, scientifically known as Palmaria palmataconsists of a short stem (stipe) and broad red-tinted fronds (leaves) that are somewhat thick and leathery in texture. All variations of this red alga contain a rich mixture of minerals, although some grow faster than others, and have various flavors depending on geographic location. Most times, the alga can be picked by hand from the shoreline, and then dried, fried, chopped, or ground for various culinary and medicinal uses.


Dulse is used to flavor soups and salads, used as an herb for flavor (particularly certain varieties that taste vaguely of bacon when fried), and as a side to meat dishes. Palmaria palmata is the most widely used variety, but there are others that can be found in more exotic locales or in export shops. It is very similar to seaweed in many ways, but tends to have more fiber and protein. It is also said by many to be more flavorful, and is a popular snack food. The wealth of nutrients makes this an incredibly good food to add to your diet, so let’s take a closer look at the many health benefits of this seaweed.


Human Health Benefits of Dulse

Build Strong Bones: 

There is a wealth of minerals found in this alga, including calcium, magnesium, and iron, all of which contribute to bone mineral density. If you’re concerned about developing osteoporosis, then ensuring that you have enough calcium in your diet is crucial for long-term health. Those minerals can also help protect joints and tissues, helping to keep you stronger into your old age.


Lower Blood Pressure: 

Potassium is another of the essential minerals found in high supply within dulse. It is well known as a vasodilator, meaning that it can help reduce the strain and damage to blood vessels and arteries caused by high blood pressure. Helping to lower blood pressure also protects against atherosclerosis, coronary heart disease, strokes, and heart attacks. Potassium can also help increase blood flow to the brain and capillaries, making this alga a bit of a “brain” food as well!


Improve Vision: 

The high levels of vitamin A found in dulse make it an ideal solution for vision problems. Vitamin A acts as an antioxidant and prevents free radicals from damaging the tissues of the eye and causing macular degeneration. Vitamin A can also slow the development of cataracts, acting as an all-around vision booster.


Boost the Immune System: 

Keeping the immune system in working order is crucial for overall health, and vitamin C is one of the easiest and most readily accessible ways to do that. Dulse is rich in vitamin C, helping the body increase its white blood cell count and contributing to growth and repair, through its important role in collagen production.


Thyroid Gland Health: 

Although many people forget that iodine is a key part of dietary health, when you thyroid gland begins to act up, a lack of iodine is usually the explanation. Dulse’s high iodine content can keep your thyroid gland behaving normally, helping to regulate many different hormonal interactions within the body. Thyroid disorders can be disastrous to quality of life, so proper iodine intake is more important than you think!


Digestive Aid: 

Similar to seaweed, dulse is very high in dietary fiber, meaning that adding it to one’s diet helps to regulate digestive processes, particularly for people suffering from constipation or diarrhea. The dietary fiber bulks up the stool and stimulates peristaltic motion, while also reducing inflammation and symptoms like bloating and cramping.


Strengthen Brain and Nervous System: 

What many people don’t know is that polyunsaturated fatty acids are not only important for heart health, but also for the functioning of your brain and nervous system. Studies have linked high levels of omega-3 fatty acids (found in good concentrations in dulse) with improved brain and activity and nervous system function.


Circulation Improvement: 

There is a huge amount of iron found in dulse, as in seaweed, and given iron’s role in the production of hemoglobin, adding this type of seaweed to your diet will aid in circulation. Having an appropriate level of iron in the blood staves off anemia, with its unpleasant symptoms of stomach and headaches, cognitive issues, and overall weakness.


Antioxidant Support: 

Many of the vitamins and minerals found in dulse, both alone and in conjunction, provide a huge amount of antioxidant support against free radicals. This means greater preventing of chronic disease and cancer prevention for those enjoying this miraculously nutritious and delicious plant!


Final Word of Warning: 

The only component of dulse with potential dangers attached to it is iodine, as ingesting too much can be toxic and disrupt your thyroid gland as much as having too little. Therefore, as with all things, consume it in moderation, and discuss any major dietary changes with a trained medical professional or dietitian.
