Analysis
A $60B Vote of Confidence
The functional drinks market is a rapidly growing industry, with a global value of £115bn and predicted to reach £230bn by 2030. This growth is driven by consumers seeking healthier alternatives to traditional soft drinks. Functional drinks are marketed as having various physiological and cognitive benefits, such as improved mental clarity, energy, and even beauty. However, can these drinks really deliver on their promises?
Why Cursor?
To investigate this, we taste-tested a selection of functional drinks, including electrolyte lemonades, probiotic fizzy pops, and energy drinks. We also spoke to consultant dietitian Sophie Medlin, who works at City Dietitians. According to Medlin, functional drinks can serve a useful purpose, but they should not be relied upon as a primary source of nutrition. "They do offer more than other regular soft drinks do," she says. "But would I encourage people to start drinking them? No. When I'm working with patients, sometimes functional drinks can help get them off less healthy things they already drink, like colas."
The Road Ahead
The functional drinks market is expected to continue growing, with new products and ingredients emerging all the time. However, it's essential for consumers to be aware of the potential risks and limitations of these drinks. As Medlin notes, "Health claims on foods, drinks, and supplements are tightly controlled in the UK, and some brands have already got into trouble with the Advertising Standards Authority." By understanding what functional drinks can really do, consumers can make informed choices and avoid falling prey to exaggerated marketing claims.
