While enthusiasts are well aware of the healthy nutritional benefits of seaweed, mainstream consumers may struggle to overcome the initial aversion associated with consuming seaweed-based products. Nevertheless, a variety of enticing options are now available to attract them. Different forms of seaweed are increasingly featured in snacks, jerky, pasta, vegetarian caviar, and even edible food wrappers. A report from Grand View Research in 2016 indicated that the global commercial seaweed market is projected to reach $22.13 billion by 2024, a significant increase from approximately $10.31 billion in 2015. The rising demand for food products derived from seaweed is anticipated to drive this market growth.
Fucoidans, which are only found in brown seaweed, are not commonly included in popular sushi dishes—except for the kelp used to flavor rice. In fact, these compounds are rarely consumed in the U.S. and are more often taken as dietary supplements.

Meanwhile, red seaweeds are preferred for their functional properties, ease of access, and applications in various industries, as reported by Grand View Research.
