Professor Tim Spector, epidemiologist and founder of Zoe Health, advises shoppers to rethink their salad choices to improve gut health and potentially reduce the risk of diabetes and cancer. His simple but powerful tip? Swap common iceberg lettuce for more colourful, bitter-tasting greens packed with polyphenols.
Polyphenols are beneficial plant compounds known for their antioxidant and anti-inflammatory effects. Unlike iceberg lettuce, which contains almost no polyphenols and offers little nutritional value, varieties like lollo rosso—a curly, red Italian lettuce—have up to 300 times more antioxidant potential.
“Polyphenols act as rocket fuel for your gut microbes, promoting the growth of beneficial bacteria,” explains Prof Spector. He recommends choosing darker, purple leaves and mixing different types of greens to increase the diversity of your gut microbiome, which supports overall health.

Zoe Health highlights that polyphenols may help regulate blood sugar levels, lowering the risk of type 2 diabetes, as well as reducing heart disease risk and offering cancer protection. Other polyphenol-rich foods to include in your shopping basket are colourful fruits, vegetables, nuts, and dark chocolate.
While ongoing research is needed to determine the safety and effectiveness of polyphenol supplements, incorporating a variety of colourful, whole foods remains the best way to benefit from these natural compounds.
Next time you plan meals, consider adding onions to your gravy or snacking on almonds with fruit and dark chocolate. These small dietary changes may support better blood sugar control and improve gut health, making a big difference in your long-term well-being.
