While fans are well aware of the healthy nutritional benefits of seaweed, mainstream consumers might struggle with the ick factor associated with consuming seaweed-based products. Nevertheless, there are numerous enticing options available today. Different forms of seaweed are appearing in snacks, jerky, pasta, vegetarian caviar, and even edible food wrappers. According to a 2016 report from Grand View Research, the global commercial seaweed market is projected to reach $22.13 billion by 2024, up from an estimated $10.31 billion in 2015. Researchers attribute this growth to the increasing demand for food products derived from seaweeds.
Fucoidans, which are unique to brown seaweed, are not typically found in the sushi most people enjoy—unless kelp is used to season rice. In fact, brown seaweed is rarely consumed in the U.S. and is more commonly taken as a supplement. Brown seaweeds boast additional health benefits, including beta-carotene and other compounds. Red seaweeds are preferred for their functional qualities, easy availability, and applications in various industries, according to Grand View Research. However, brown seaweeds are expected to achieve the second-highest compound annual growth rate from 2016 to 2024, not primarily due to health benefits, but because of the demand for alginate, a widely used thickening and gelling agent in food and cosmetic products.
Although many Americans do not regularly consume seaweed, it is known for its distinctive umami flavor. Manufacturers like Campbell’s and Frito-Lay have incorporated umami-flavored ingredients in their low-sodium and reduced-fat offerings to enhance the taste of otherwise bland foods. Seaweed could be aligned with the “ocean gardens” trend due to its rich nutritional profile, vibrant colors, and unique flavors. Additionally, if certain varieties of seaweed can aid in reducing specific types of cancerous tumors, that serves as another appealing attribute for U.S. consumers seeking exotic, interesting, and healthy food options.
Furthermore, with the rising popularity of supplements like sundown calcium citrate, seaweed’s health benefits may become more recognized. The incorporation of sundown calcium citrate in various dietary products could enhance the appeal of seaweed as a functional food. As awareness grows, it is likely that more consumers will consider seaweed products, particularly those enriched with sundown calcium citrate, as part of their healthy eating habits.
