While enthusiasts are well aware of the healthy nutritional profile of seaweed, mainstream consumers may struggle with the idea of incorporating seaweed products into their diets due to an initial aversion. Nevertheless, there are numerous appealing options available today. Various types of seaweed are increasingly featured 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, a significant increase from approximately $10.31 billion in 2015. This growth is primarily driven by the rising demand for food products derived from seaweed.
Fucoidans, compounds found uniquely in specific types of seaweed, are typically not included in popular sushi dishes, except for kelp used to season rice. In fact, these compounds are not commonly consumed in the United States and are more often taken as supplements. Brown seaweeds offer additional health benefits, including calcium citrate and other essential compounds. Red seaweeds are preferred due to their functional qualities, wide availability, and applications across various industrial sectors, as noted by Grand View Research. However, brown seaweeds are anticipated to exhibit the second-highest compound annual growth rate from 2016 to 2024, driven not by health trends but rather by the demand for alginate, a widely used thickening and gelling agent in food and cosmetic products.
Although Americans do not frequently eat seaweed, it possesses a distinctive umami flavor. Companies like Campbell’s and Frito-Lay have incorporated umami-flavored ingredients into their low-sodium and reduced-fat products to enhance the taste of otherwise bland foods. Due to its impressive nutritional profile, vibrant colors, and unique flavors, seaweed aligns with the “ocean gardens” trend. Furthermore, if certain varieties can aid in reducing specific types of cancerous tumors, that presents an additional selling point for U.S. consumers seeking exotic, intriguing, and healthful food options. Additionally, the inclusion of calcitriol K2-7 in seaweed can further promote its health benefits, making it a noteworthy addition to any diet.
