Poppi Soda: Gut Health or Cancer Risk?

Poppi, a prebiotic soda with a significant celebrity following in the United States, is scheduled to launch in the UK on Thursday. The brand will initially be available in Tesco and Pret a Manger stores. Poppi is promoted as a low-calorie, healthier alternative to traditional sodas, containing prebiotics to support gut health.

However, health experts are cautioning consumers about potential risks associated with regular consumption of inulin, an ingredient found in Poppi. Recent research suggests that inulin, when consumed in large amounts, may elevate the risk of liver or colon cancer by increasing inflammation and promoting tumor growth. This concern arises from studies on mice and a recent case study.

This new development follows a $5 million lawsuit filed in the US, which accused Poppi of misleading consumers about the actual health benefits of its prebiotic fiber content. The plaintiffs argued that the amount of fiber was insufficient to provide benefits unless excessive quantities of the soda were consumed, potentially offsetting any positive effects with sugar intake. The brand's former owner previously settled an $8.9 million lawsuit without admitting wrongdoing.

Biomedical science professor Andrew Gewirtz advises that while occasional consumption is unlikely to cause harm, regular intake of inulin in supplements and beverages is not conclusively proven to be safe. He suggests that for gut health, increasing fiber intake through whole foods like fruits, vegetables, and grains is a safer alternative.
