Certain diets linked to obesity may improve cancer immunotherapy in mice

Scientists have discovered that some diets typically associated with obesity can improve the effectiveness of cancer immunotherapy in mice, according to ScienceDaily Health.

The research, co-led by Daniela Quail at the Rosalind & Morris Goodman Cancer Institute, suggests that the interaction between diet and gut bacteria plays a crucial role in how the immune system responds to cancer treatment.

The study focused on immune checkpoint inhibitors, a common immunotherapy that helps the immune system recognize and attack cancer cells, and found that certain 'unhealthy' diets enhanced treatment response.

These findings challenge the traditional view that only healthy diets support cancer treatment, highlighting a complex relationship between nutrition and therapy outcomes.

However, the researchers caution that these results should not be taken as advice for cancer patients to adopt obesogenic diets, as excess weight carries other health risks.
