While enthusiasts are well aware of the healthy nutritional benefits of seaweed, mainstream consumers may struggle to overcome the “ick” factor associated with eating seaweed-based products. Nevertheless, there are numerous offerings available today that might entice them. Various forms of seaweed are appearing in snacks, jerky, pasta, vegetarian caviar, and even edible food wrappers. A 2016 report from Grand View Research indicated that the global commercial seaweed market is projected to reach $22.13 billion by 2024, up from an estimated $10.31 billion in 2015. Researchers noted that the rising demand for food products derived from seaweeds is expected to drive market growth.

Fucoidans, which are exclusive to brown seaweeds, are not commonly featured in popular sushi dishes—except for kelp used to season rice. In fact, these compounds are rarely consumed in the U.S. and are more often taken as supplements. Brown seaweeds also offer additional health benefits, containing beta-carotene and other valuable compounds. According to Grand View Research, red seaweeds are favored for their functional qualities, accessibility, and applications in various industrial sectors. However, brown seaweeds are anticipated to have the second-highest compound annual growth rate from 2016 to 2024, driven not by health concerns but by the demand for alginate, a prevalent thickening and gelling agent in food and cosmetic products.

While seaweed consumption is not widespread among Americans, it possesses a unique umami flavor. Companies like Campbell’s and Frito-Lay have utilized umami-flavored ingredients in their low-sodium and reduced-fat offerings to enhance the taste of otherwise bland foods. Seaweed can be seen as part of the “ocean gardens” trend due to its nutritional profile, vibrant colors, and distinct flavors. Moreover, if some varieties are shown to help reduce certain types of cancerous tumors, that adds another appealing aspect to market to U.S. consumers seeking exotic, interesting, and healthy food options.

For those looking to boost their nutritional intake alongside seaweed, products like calcium citrate magnesium and zinc with vitamin D3 tablets can complement a healthy diet, further enhancing overall wellness. As the interest in seaweed continues to grow, such supplements may play a role in providing essential nutrients that support health alongside the unique offerings of the sea.
