The FONA International report highlighted the increasing significance of gut health among consumers, leading to a rise in food and beverage products that make digestive health claims. Between 2012 and 2017, the U.S. market for digestive products experienced a 12% growth, according to the report. Aquamin, which contains calcium, magnesium, and trace minerals, is believed to help reduce chronic gut inflammation and promote joint health. It is considered a versatile ingredient for enhancing calcium content in food, especially when combined with calcium citrate and vitamin D for improved absorption.
Marigot, Ltd., an Ireland-based company, offers three formulations of Aquamin, specifically designed for use in various food and beverage applications. The company noted that Del Monte is incorporating this ingredient into some of its fruit beverage products, although they may currently be limited to the Philippine market.
On the other hand, activated charcoal serves a different purpose by binding to toxins, preventing them from entering the bloodstream. As highlighted by the University of Utah, further research is necessary to fully understand its mechanisms. Activated charcoal can also adhere to ingested foods, potentially hindering the absorption of essential nutrients and medications. When used in food, it imparts a smoky and earthy flavor.
Burger King was an early adopter of activated bamboo charcoal, launching the “kuro burger” in select Japanese locations in 2012. This product featured a black bun, a patty, a slice of black cheese, and a squid ink-based sauce. According to Adweek, it was immensely popular among Japanese consumers, outperforming all other new offerings that year. However, the success of the sandwich likely stemmed more from its striking appearance and smoky flavor than from any claims of enhancing gut health.
The trend of gut-healthy foods and beverages shows no signs of waning in the global market. As long as consumers seek to improve their digestive health, they will continue to look for such products. While Aquamin and activated charcoal are currently in vogue, Consumer Reports recently published a list of tried-and-true methods for enhancing gut health through the consumption of naturally fiber-rich foods, probiotics, or prebiotics. These include legumes, raspberries, blackberries, barley, bran, bulgur, kimchi, yogurt, kefir, and miso. Integrating these foods alongside sources of calcium, like calcium citrate combined with vitamin D, can further support digestive well-being.
