Giving you the green light to enjoy food again
Right now, you might be feeling at a loss for how to best support yourself through long-term health issues that just won’t seem to go away. Whether you’re struggling with persistent digestive symptoms, the side effects of cancer treatment, or women’s health conditions like endometriosis, food may feel like more of a problem than a pleasure right now.
You’ve likely spent hours researching online, listening to advice from well-meaning friends, or even following restrictive diets that left you confused and a little bit miserable.
The good news is, we can support you. Our team of experts are here to change the way you think about food and health – so you can find relief, regain confidence and rediscover the joy of eating.
Hi, I’m Jo Cunningham, the founder of Green Light Nutrition.
Like many of my clients, my relationship with food hasn’t always been easy.
My own battle with IBS led me down a rabbit hole of bad advice, misinformation and expensive “specialists”. Having paid for pricey food intolerance tests through a nutritionist, and being “diagnosed” with multiple food intolerances I got curious into the validity of the tests, which I discovered were completely ineffective – not to mention scientifically unproven!
That experience opened my eyes to the vast differences in nutrition qualifications and the importance of evidence-based practice. So I decided to retrain as a Registered Dietitian – the gold standard in nutrition professionals.
In addition to my own digestive issues, I lost my dad to oesophageal cancer in my early twenties. Watching him go through treatment, I saw first-hand how much fear and uncertainty surrounded his food choices – and how little expert nutrition support was available to help him on the NHS.
Green Light Nutrition exists to stop the misinformation and give you a space for honest, science-backed nutrition advice that doesn’t just focus on what you shouldn’t eat. We’re here to help you find clarity, confidence and joy in eating – without unnecessary restrictions or endless guesswork.
A knowledgeable team of trusted experts, by your side.
While my personal journey brought me here, Green Light Nutrition isn’t just about me.
I’m proud to work alongside a team of expert dietitians, each specialising in either oncology or digestive health – or both!
Whether you’re navigating cancer treatment or looking for relief from debilitating conditions, like IBS, PCOS or endometriosis, you’ll have the opportunity to work with someone who understands your specific needs and has the expertise to guide you.
Together, we provide personalised, science-backed advice tailored to your unique circumstances. Our approach isn’t about telling you what you can’t eat – it’s about exploring everything you can enjoy, so food becomes a source of comfort and connection again.

The Green Light Approach:
Focusing on what you can enjoy
So much of what’s out there – online, in well-meaning advice from friends, and even from some nutrition professionals – leaves people feeling confused, restricted and defeated.
That’s not how we work. At Green Light Nutrition, we:
Focus on what you can add, not take away. Food is meant to be enjoyed. We start by building a foundation of nourishing, diverse options tailored to your needs, only recommending restrictions when absolutely necessary.
Prioritise science over fads. Our advice is grounded in the latest research, ensuring it’s not just effective but also safe.
Take a holistic view. We consider not just your symptoms, but your lifestyle, goals and emotional wellbeing to create strategies that truly work for you.
Work with other healthcare professionals (where necessary) to provide you with connected, supportive treatment and come up with a protocol together.
Whether it’s helping you feel more confident eating out, managing treatment side effects or simply finding relief from years of discomfort, we’re here to guide you every step of the way.
