Some 'fattening' diets boosted cancer immunotherapy in mice

Researchers co-led by Daniela Quail of McGill's Goodman Cancer Institute found that certain diets linked to weight gain made immune checkpoint inhibitor drugs work better in mice, apparently through effects on gut bacteria. Published in Nature, the study suggests the foods that feed gut microbes can shape treatment response. The team stresses patients should not adopt obesity-promoting diets based on this.
