A no-nonsense, evidence-based guide, just for you

Navigating all the information around diet and cancer can be overwhelming. There’s a lot of confusing stuff out there and we know you probably don’t have the time or energy to digest it all. So we’ve created this guide to everything you might be asking about how what you put into your body affects it during treatment and beyond.

We ran a survey and found that 43% of our community consult the Internet for advice or information on nutrition and 20% refer to social media, 45% said they feel social media makes them confused about what to eat, and less than half said they felt comfortable discussing their diet with their oncology team.

We’ve included the latest research and unpacked controversial topics in a balanced way offering you all the information you need to make decisions that work for you. A huge thank you to our expert contributors; Dr Hazel Wallace, Dr Ailsa Sita Lumsden, Dani Binnington, Camilla Ferraro, Monika Siemicka, Sarah Dixon and Alice May Purkiss.

You never expect to get diagnosed with cancer, let alone when you’re in your 20s or 30s. When it does happen, it understandably shakes every aspect of your world. You don’t need me to tell you how much of a shock a cancer diagnosis can be, how hard treatments are, how difficult recovery can be, or how much it can change the way you feel about yourself and your body. Finding some sense of normality is key at such a turbulent time.

If there’s one thing that remains totally constant throughout your treatment and recovery, it’s the need to give your body the support necessary to deal with all of the treatments and stresses that are being thrown at you. Food can play an important role here. But the internet, and of course social media, is the modern-day equivalent of the Wild, Wild West – full of misinformation, dubious claims, and conflicting advice. When we asked, 45% of you said that social media makes you confused about what to eat. So, how do you know what to trust and what to listen to? It’s a minefield, but hopefully, we can help with that.

"When I came on board as a Trekstock Ambassador, I realised there was a need for a nutrition resource that was available specifically for people going through cancer treatment and recovery. So Trekstock and I brought together a group of doctors, dietitians, patients, and members of the Trekstock community to create a no-nonsense, evidence-based, and easy-to-follow nutrition booklet to help support you."

I promise this is not another prescription and we invite you to dip in and out of it whenever you feel the need to. Remember, dealing with cancer is enough pressure for anyone, so try to be as kind as possible to yourself when you’re thinking about what to eat. Food should be a pleasure as well as something to fuel your body with, so enjoy what you’re eating when you can, and don’t beat yourself up if you’re not eating what you think you ‘should’.

I hope you find this resource, and some of the further notes we’ve included in the back, empowering and helpful.

Happy eating,

Dr Hazel Wallace @TheFoodMedic
