Five Interesting ocean foods

1. Ecklonia cava

Origin: It is a type of brown algae that is common in Japan and Korea. It is harvested from the coastal regions and are a part of traditional Japanese and Korean cuisine.

Key ingredients: Polysaccharides, polyphenols and phlorotannins. Other nutrients include iodine, calcium, niacin, vitamin A, potassium, phosphorus.

Health benefits:

Anti-inflammatory: This species of brown algae exhibit anti-inflammatory properties due to the presence of the polysaccharide component. The polysaccharide component of this algae was found to decrease the production of nitric oxide which is critical in the inflammatory conditions. One study showed that the polysaccharides extracts from the fermented ecklonia cava exhibited anti-inflammatory properties by down regulating the pro-inflammatory reactions in the body. (1)

Anti-bacterial: The Japanese included plenty of this brown algae in their traditional food owing to its potent anti-bacterial effect. A study showed that ecklonia cava demonstrated potent anti-bacterial activity against two strains of bacteria staphylococcus aureus and salmonella(2)

Potent antioxidant: The phlorotannins and the polyphenol components in ecklonia cava exhibit antioxidant effect against reactive oxygen species and oxidative stress. A recent 2011 study revealed that a specific natural antioxidantive compound pyrogallol-phloroglucinol-6,6′-bieckol (PPB) isolated from the algae effectively inhibited the DNA damage caused by the free radicals (3).

2. Nori

Origin: It is a type of seaweed from a red algae that belongs to the genus Porphyra. It is an integral part of Japanese cuisine and is consumed fresh or as dried sheets in sushi preparations. The Japanese traditionally value Nori for its health effects of longevity and well-being.

Decreases blood cholesterol: Nori is rich in the aminoacid taurine, the compound that is responsible for  preventing gallstones in liver by controlling blood cholesterol levels. The water soluble dietary fiber galactan, is responsible for decreasing the high blood cholesterol levels(4).

Improves heart health: The high levels of the essential fatty acid EPA, presence of the beneficial compounds porphyosins and betaines help in preventing blood clot and are significant in maintaining heart health. The presence of all essential aminoacids is considered as one of the factors for the profound heart health benefits of Nori.

Beneficial as a diabetic dietary supplement: Most diabetics are nutritionally deficient in minerals such as selenium and copper which play a role in glucose metabolism. Including nori as part of diabetic effect may eliminate fatigue and acts as a good food supplement.

3. Arame

Health benefits:

Immune support: The nutrients present in Arame form the essential raw material for the immune building. They nourish the immune system and aids in its optimal function.

Anti-cancer effect: The compound pheophytin from Arame was identified to exhibit anti-cancer effect. The presence of lignans, a class of polyphenolic compound demonstrates antioxidant effect and deter the development of certain types of cancer.

4. Dulse

Origin: It is a type of reddish-brown sea weed and grows in the northern coasts of Atlantic and Pacific ocean. It is a part of traditional Japanese cuisine for more than hundred years. The Dulse has a strong odour and taste in its fresh form.

Health benefits:

Aids in weight loss: Dulse is a low calorie, nutrient-dense food. It is high in protein and fiber content. The fiber rich component adds bulk to the diet which stimulate the hunger pangs at a slower rate. The enzymes also help in the digestion and decrease the risk of gastro-intestinal disorders such as constipation.

High nutritional value: The nutritional profile of Dulse is diverse and is an important source for vitamin B12, C, B and A. The nutrients in Dulse helps enhance the activity of the immune system. ?Promotes thyroid health: It is naturally rich source of iodine and helps to maintain thyroid. It is also a good source of  other trace minerals that are required for optimal secretion of hormones and promotes hormonal health.

Sea vegetables can also be a healthy replacement for some common ingredients in our every day cuisine. The dried or powdered form of these vegetables can be used as a replacement for table salt or artificial seasoning for soups. Sea vegetables do not require cooking, however some of them need to be soaked in water for about 10 minutes prior to adding to the dishes. Ocean vegetables not only add taste to the cuisine but also support health.
