Anticancer diet, lifestyle and supplements with Integrative Oncologist Professor Robert Thomas

Up to 40% of cancers are attributable to modifiable risk factors, including diet, obesity, alcohol, tobacco use, and physical inactivity. The World Cancer Research Fund estimates that about 1 in 3 cancer cases in high-income countries could be prevented by healthier diets, maintaining a healthy weight, and regular physical activity.

But even with the best intentions, there’s a lot of confusion around lifestyle and cancer. One day it’s red meat, the next it’s microwaves. We hear about them in headlines, social media posts or passed around in conversation, which can make it really hard to know what matters most.

I’m joined today by Professor Robert Thomas, an NHS oncologist and researcher who’s spent decades studying how lifestyle (from food and movement to gut health and supplements) affects cancer risk and recovery.
