Which seaweed to eat

It can be eaten raw or can be cooked in stews and soups, some people even make risotto out of it. It can also be made into a type of fritter by chopping finely, boiling for half an hour, mixing with grated cheese and oatmeal before forming into patties and frying. It can vary in colour from olive green through reddish brown to almost black and typically about 40cm in length though fronds can grow up to 1m long.

While this is most commonly used as a food in Japan, interest in the West is growing, as, being a thyroid stimulant, some experts think it could counter obesity by increasing the metabolic rate. Typically it is stored dried and makes a very nutritious tea as well as being used in soups particularly Japanese-style noodle soups and can be added to any soup or stew as a flavouring.

It grows profusely just under the water at low tide and can spread over a very wide area. They are brown seaweeds, with elongated, branched, fronds that can grow to 1. It also dries well for later use. It is extremely useful in that it provides the umami flavour making any dish more moreish and can speed up cooking times in, for example bean stews as it softens the beans and thickens the stew at the same time. Common kelp becomes translucent, tender and very tasty after extended boiling.

Samphire grows in cracks in the rock in cliffs or on stoney ground above the tide mark — its fleshy leaves are rich in iodine and can be used principally to flavour soups or salads.

Drain and serve on warm plates with melted butter. This is a cabbage-like plant growing close to the sea in shingle or shingle and sand. This was very popular in the 19th Century and commercial demand actually depleted numbers quite dramatically. Early spring is the best time to pick — the young leaves, stalks and broccoli-like flower heads are all edible but become a bit tough and bitter later in the year.

Treat sea kale pretty much like purple sprouting broccoli — wash well and cut away any tough stalks, steam or boil in salted water for minutes until tender then toss in butter and season with black pepper and sea salt. Now this is the mother of all spinach! The ancestor of our cultivated forms of beet from Swiss chard to beetroot. The thick, leathery leaves are even more succulent than those of cultivated spinach varieties; leaves can be picked all spring and summer from about late March.

Here's what you need to know. We asked some of our inspectors to share with us the ingredient they love the most and why. Everything you wanted to know about Chesapeake blue crab season, but were afraid to ask.

Global English. Dining In 2 minutes 16 May Edible seaweed is a vegetable of the sea, a food source for ocean life and humans who consume it in its many forms. Nutritionally speaking, seaweed has the unique ability to absorb concentrated amounts of iodine from the ocean which a human body cannot produce by itself, but requires for healthy thyroid functions.

Seaweed is also an excellent source of micronutrients including folate, calcium, magnesium, zinc, iron and selenium. Low-calorie and nutrient-dense, edible seaweed has long been harvested and consumed in Asian cuisines, particularly those of Japan and Korea. An essential part of many familiar Japanese dishes from miso soup to sushi rolls, the different varieties of seaweed are more commonly known around the world by their Japanese names.

What kind of seaweed goes into the sheets of seasoned crispy seaweed snacks we love so much? What kind of seaweed makes agar-agar jelly? Which algae is known as the green caviar? We check out six common varieties of seaweed and their food applications. Nori Also known as zicai in Chinese or gim in Korean, nori is perhaps the most recognisable seaweed on this list. The red seaweed usually comes pressed into thin dried sheets that are dark green or black which we eat as a snack or use to make sushi rolls.

Dried or toasted nori sheets absorb moisture easily from the air and should be stored in air-tight containers with a desiccant to prevent it from turning soft.

Kombu A member of the kelp family, kombu is the integral ingredient for making dashi , a clear but flavourful stock that is the cornerstone of Japanese cuisine. This brown seaweed is usually sold dry in in wide strips and reconstituted for dashi, shabu-shabu broth and as a seasoning for sushi rice. A powdered form of kombu is also used to make a Japanese tea called kombucha , not to be mistaken for the trendy fermented probiotic drink of the same name.

Umibudo Sea grapes are one of the few seaweed varieties sold fresh rather than dried to preserve the tiny clusters of bubble-like leaves that grow on long stems. Like caviar, the tiny pearls burst in the mouth when eaten and release the brininess of the sea. Blanching and shocking them in cold water removes the extra salt and in Okinawa they are often enjoyed raw with soya sauce.

According to the study in Marine Drugs , a high amount of dietary fiber delays stomach emptying. As a result, the stomach may not send signals of hunger to the brain for a longer time, which may help prevent overeating. As the same study notes, high-fiber foods such as algae may also reduce levels of cholesterol in the blood.

These soluble fibers bind to bile acids or salts in the body. The body then uses cholesterol to replace these elements, which may result in a decrease of total cholesterol by up to 18 percent. Many types of algae also have high levels of antioxidants, which may also support heart health over time. Most seaweed contains high levels, and a person may consume too much if they eat a lot of seaweed over an extended period.

While many people can handle high levels of iodine, some are more vulnerable to its effects, which can include thyroid dysfunction. A resulting condition could cause symptoms such as weight gain or swelling and tightness around the neck. Anyone experiencing these symptoms should stop consuming iodine and see their doctor for a full evaluation. Another common concern involves heavy metals. Seaweed absorbs minerals and nutrients from the sea. If the surrounding water contains these metals, the seaweed will absorb them as well.

A study in Chemosphere found that in edible seaweed, levels of the toxic metals aluminum, cadmium, and lead are generally very low. Also, a study in Scientific Reports investigated 10 potentially dangerous metals in seaweed and came to a similar conclusion, though the authors called for more research into other metals. While levels may be low, toxic metals may build up over time in a person who eats seaweed every day.

Though the general risk is low, it may be a good idea to ensure that seaweed is organic and derived from a high-quality source. Adding seaweed to the diet can be very simple. The big sheets of dried nori used in sushi also make a great substitution for tortillas or bread, and they can make delicious wraps.

Also, many companies produce roasted seaweed with a little oil and salt, which can be a perfect way to satisfy a salty craving. Toasted seaweed or seaweed flakes can be a great topping for grains such as rice or quinoa and may help reduce the amount of salt or soy sauce a person needs. Seaweed is a welcome addition to most diets. The flavor can boost a variety of recipes, the nutrient content can support a healthful diet, and people can often use seaweed blends in place of salt.

For some people, however, it is a good idea to avoid seaweed. Anyone taking thyroid medications should talk to their doctor before adding seaweed to the diet. Hypothyroidism is when the thyroid gland is not making enough hormones for good health. Symptoms can progress slowly and be vague and hard to identify.
