science-backed cancer nutrition advice you can trust
Wondering what to eat after you've been diagnosed with cancer?
If you or someone you know has recently been given a cancer diagnosis, you probably have a lot of questions around food and diet.
What are the best foods to eat if you have cancer?
What shouldn’t you eat during chemotherapy?
How can I eat when I’m being sick?
Is sugar and dairy the enemy?
What about inflammation?
Should you follow a Keto or Vegan diet, or try intermittent fasting during cancer treatment?
The truth is, you’re unlikely to be doing anything that will make your cancer worse, but it’s time to stop the endless Googling.
If you’re looking for legitimate, research-backed diet advice from a registered cancer nutritionist, you’re in the right place
"Nobody within the NHS clinical setting was able to help mum, including the dietetic team, and mum was seriously unwell and failing to thrive. I reached out to Green Light Nutrition who offered an immediate consultation. The dietitian was able to offer clear advice and a protocol to follow. For the first time in months, mum is eating with significantly reduced pain and restoring weight."

Our personalised cancer nutrition advice is focused on adding what’s nourishing – not removing what you love
At Green Light Nutrition, we have specific expertise in managing nutrition for cancer patients, at every stage – and have been selected as oncology provider to King Edward VII hospital in London as well as KIMS cancer centre in Kent.
Whether you’re newly diagnosed, undergoing treatment, living with metastatic disease, or looking to optimise your health post-cancer, our team of cancer specialist dietitians are here to support you every step of the way with advice tailored to your unique needs.
One thing we always stand behind is this: You have enough on your plate, without removing everything you love from your actual dinner plate. That’s why we’ll always aim to add things to support you throughout treatment and recovery, rather than taking away the treats that get you through the day.

"The session with the dietitian was worth every penny, Claire explained all the science behind nutrition during chemotherapy and after, what is important and what to add to your diet. Afterwards I received a detailed report of nutritional advice. Definitely recommend."

“So well informed”
“Jo is fantastic. I started working with her before undergoing the Whipple procedure to remove a tumour from my pancreas, as my digestive system was to change quite drastically. She was so well informed about this procedure and what I'd need in the build up and after. She is thorough, helpful, kind and very quick to respond - always looking to answer questions and find solutions which is invaluable when working alongside the NHS who are brilliant but don't necessarily have the time to investigate complicated problems thoroughly. Would recommend to anyone in need of nutritional advice.”
