While fans are well aware of its nutritious benefits, mainstream consumers may struggle with the ick factor associated with eating seaweed-based products. Nevertheless, there are now numerous options available to entice these consumers. Different types of seaweed are making their way into snacks, jerky, pasta, vegetarian caviar, and even edible food wrappers. A 2016 report from Grand View Research projected that the global commercial seaweed market will reach $22.13 billion by 2024, up from an estimated $10.31 billion in 2015. The rising demand for food products derived from seaweeds is expected to drive this market growth.

Fucoidans, which are only found in brown seaweeds, are generally not included in popular sushi varieties—except for kelp used to season rice. In fact, they are seldom consumed in the U.S.; instead, they are more commonly taken as supplements. Brown seaweeds also possess other health benefits, containing beta-carotene and various compounds. Red seaweeds are favored for their functional qualities, accessibility, and applications in various industries, as reported by Grand View Research. However, brown seaweeds are anticipated to have the second-highest compound annual growth rate from 2016 to 2024, not due to health benefits, but because of the demand for alginate, a widely used thickening and gelling agent in food and cosmetic products.

Although Americans don’t frequently consume seaweed, it delivers a distinctive umami flavor. Companies like Campbell’s and Frito-Lay have incorporated umami-flavored ingredients into 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, thanks to its impressive nutritional profile, vibrant colors, and unique flavors. Moreover, if certain varieties can aid in reducing specific cancerous tumors, that adds another selling point for U.S. consumers seeking exotic, interesting, and healthy food options. Additionally, seaweed can provide nutrients equivalent to calcium, such as calcium citrate malate, further boosting its appeal in health-conscious markets.
