Sea vegetables and edible seaweeds make their menu debut

Seaweed Consumption on the Rise

If you run a foodservice business and want to know what’s trending in the industry and what is expected to increasingly appear on 2019 restaurant menus everywhere, it’s time to learn all about the seaweed, aka sea vegetables. Recent Nation’s Restaurant News headlines reveal that seaweed is experiencing a tide of popularity, while James Griffen, an associate professor at Johnson & Wales University, reports that consumption of seaweed is growing 7% annually in the United States – and for good reason. Bursting with a rich array of nutrients and associated with multiple scientifically proven health benefits, the growing appetite for sea vegetables such as nori, kombu, and wakame is not expected to wane anytime soon.

What are Sea Vegetables?

So, what exactly are sea vegetables and how can you add seaweeds to your recipes and menus? Neither plant nor animal, sea vegetables are classified under a group known as algae. Also referred to as edible seaweed, they grow in marine salt waters as well as fresh water lakes and seas and are commonly found on coral reefs or in rocky landscapes. While relatively new to the Western palate, seaweed varieties have been a staple of Japanese diets for millennium. Remarkably, while some types of sea vegetables require soaking for 5-10 minutes before adding them to your recipes or dishes, most require no cooking or sautéeing whatsoever. Due to growing demand, while once available only in specialty shops and health food stores, you can now increasingly find seaweed varieties in local supermarkets and grocery stores as well.

Types of Edible Seaweed

Seaweeds are categorized into three main groups, based on color:

  • Green Seaweed: Rich in chlorophyll; found in dark leafy greens and other green vegetables
  • Red Seaweed: Especially high in carotenoids; known to have anti-inflammatory properties
  • Brown Seaweed: Formidable source of iodine; popularly referred to as ‘kelp’

Seaweed and Sea Vegetables: Health Benefits

Seaweed and its edible members, sea vegetables, have quickly earned a ‘superfood’ status due the extensive health benefits they offer. Their most important contribution is the wealthy dose of iodine provided, which is an essential ingredient for thyroid and hormonal health. In addition, they contain a wide variety of essential minerals such as calcium, copper, magnesium, and iron. Sea vegetables also alkalize the blood, helping balance internal pH levels, and they draw toxins and harmful chemicals out of the body. And if all these have not whet your appetite for a mouthful of edible seaweed, you may want to start adding sea vegetables to your diet for their beauty benefits, which include improving the appearance and condition of your skin, hair, and nails.

Here is a breakdown of some additional nutritional qualities of seaweeds and their effect on the human body:

  • Rich in chlorophyll, which nourishes red blood cells, helps cleanse and detoxify, and helps prevent certain types of cancer
  • Good source of antioxidants and Vitamin C, boosting immunity and helping with iron absorption
  • Good source of protein
  • High in B vitamins, boosting energy levels and relieving stress
  • Rich in polysaccharides called fucoidans, which are known to have immune-boosting, anti-inflammatory, and cancer-preventing properties
  • A significant source of compounds that are said to have anti-breast cancer and anti-colon cancer effects
  • Rich source of natural salt, making them a great alternative to commercial table salt
  • Promote the growth of healthy hair and help maintain the skin’s youthful elasticity

Seaweed and Sea Vegetables: Health Benefits

History of Sea Vegetables

Archeologists trace the consumption of sea vegetables to ancient Japanese and Chinese cultures many millennia ago, when they were first considered a delicacy fit for royalty and honored guests and where they gradually became more widely consumed. Additional Asian countries with a long history of seaweed consumption include Malaysia, Korea, and Vietnam, while multiple coastal countries and regions located near water have also been including sea vegetables in their diets since ancient times. These include the Pacific Islands, coastal South America, Iceland, New Zealand, Norway, Scotland, and Ireland.

Surplus production of seaweed led to the beginning of exports to Europe, France, and eventually to the United States and elsewhere, where acceptance of seaweed products as human food and cultivation of sea products has been slow in coming. Today, investments in the equipment and expertise necessary for edible seaweed cultivation have expanded outside of Asia, however Japan continues to dominate and corner the market on production.

Guide to Popular Types of Sea Vegetables

There are countless seaweed varieties in the natural world! Here is some practical information about the most popular types of edible seaweed and how your restaurant or catering service can incorporate sea vegetables into your existing menus and favorite recipes.

Nori: Out of all the sea vegetables, nori is among the best known, made famous for its role in making sushi rolls. Naturally dark black-purple in color that turns phosphorescent green when toasted, nori is available in sheets, flakes, or powder, toasted and pre-toasted. To make vegan sushi rolls in your restaurant, simply wrap cooked rice and your favorite veggies in sheets of nori. Delicious with the addition of a homemade dip or served with tamari or avocado slices. For a finishing touch, you can also serve with a crispy, salty nori snack (like a potato chip).

Hijiki: Traditionally used in Chinese medicine to promote beautiful lush hair locks (aka healthy hair growth), hijiki is packed with minerals that give it its dark black appearance. But don’t let looks scare you, in addition to its being a natural beauty aid, hijiki is also a salad-friendly seaweed. Some of the ways to enjoy hijiki is rinsed, drained, and mixed with sautéed tofu, carrots, or mushrooms. For another great serving idea and easy recipe, combine soaked hijiki with shredded carrots and ginger. Toss with some soy sauce and a dab of olive oil – and voila!

Kombu: A dried sea vegetable dark in color, kombu increases the flavor of other foods and is often added to soups. Alternatively, you can add strips or slices of kombu (softened by soaking in water) to assorted salads, vegetable dishes, and grains.

Wakame: Resembling kombu in appearance and usage, wakame is a popular ingredient in making Japanese miso soup. You can also soften wakame by soaking it in water and adding it, drained and chopped, to your favorite grain and salad recipes. And if you are a chef who is always hungry for new ingredient information, here is some culinary trivia for you to savor: In macrobiotic cooking, miso soup is consumed in the morning as a means of getting the body ready for the day ahead. Add in some tofu and wakame, and enjoy a protein-packed, nutrient-rich breakfast!

Guide to Popular Types of Sea Vegetables

Arame: Part of the kelp family and known for its sweetness and mild flavor, arame is a wiry sea vegetable sold in thin strips and is used similarly to wakame. For example, you can substitute arami for wakame in soups and other dishes. Dried arame can also be rehydrated by soaking in water and draining, and you can add arame strips to stir fries and salads.

Word to the seaweed wise: If sea vegetables are new to your customers’ palates, arame is a great way to begin due to its sweet taste and crispy natural texture. Simply toss some arame into a green salad, and you instantly have a new delicious, mineral- and protein-rich recipe!

Kelp: A popular brown edible algae, kelp grows in nutrient-rich ocean waters, giving it its notably high iodine, vitamin, and mineral content. Healthwise, kelp is said to especially boost thyroid function, the digestive system, the prostate, and the pancreas. As a natural beauty aid, the minerals in kelp contribute to youthfulness and splendor while they prevent hair loss, dry skin, and brittle nails.

Typically sold in flake form, a growing number of restaurants keep a container of kelp flakes or kelp seasoning on their customers’ tables, right next to the traditional salt and pepper shakers. And for another great seaweed recipe idea, try your chef’s hand at preparing kelp noodles, which are not only nutrient rich but also a gluten-free and low-carb alternative for your customers on restricted diets. Kelp noodles can be added to soups, stir-fries, and salads, or for a spicier rendition, toss with some Thai peanut sauce or other Asian sauce.

Agar: Also known as agar-agar, this sea vegetable is fast becoming a secret ingredient in mouth-watering, sweet, sugar-free desserts! Remarkably, while agar is naturally odorless and flavorless, it can be used as a vegan alternative to gelatin (i.e. in custard and pudding recipes) as it shares the same consistency when soaked, and also adds a healthy dose of collagen. Alternatively, you can add agar to savory dishes to help create a thicker gravy base.

Dulse: Looking for a ready-to-eat seaweed with a salty, slightly sweet taste and chewy texture? Then consider adding reddish-brown dulse to your menus, as it not only requires no soaking or cooking, but it comes naturally loaded with iron and protein. (It is also said to contribute to thick, shiny hair!)
