We are pleased to announce the next intake of this innovative course, designed for entry to the nutrition and lifestyle medicine profession.

On our Graduate Diploma in Integrative Functional Nutrition, validated by the University of Portsmouth, you will learn how to incorporate the principles of functional medicine and personalised nutrition into your existing clinical practice. 

Created by the Institute for Optimum Nutrition (ION), a long-established and well-respected independent education provider based in Richmond, London, the course is specifically for doctors and allied healthcare professionals (with core sciences), enabling study with fellow health professionals across sectors.

Through the Graduate Diploma in Integrative Functional Nutrition, you will discover in depth perspectives on the role that nutrition and lifestyle plays in human health. The course is practice-focused, with learning centered on case histories and reflection on student-led fieldwork. In each of the nutrition modules, you will explore dietary, nutraceutical and lifestyle approaches for optimising health and test interpretation.

Dr Mayoni Gooneratne, a General Surgeon currently studying with ION, commented: 

I think every doctor has a duty of care to know about nutrition – there’s no getting away from it… So much chronic disease, if you go to the stats, has got such an absolute foothold in nutrition and lifestyle. We can make such a difference.

Why are we not all practising medicine like this? And I get it, I’ve been a surgeon in a busy NHS clinic where you’ve got ten minutes and you’ve been presented with someone with a lump or a bleed and you basically want to exclude cancer. And that is correct, that’s ultimately what the NHS is fantastic at. But all the bits that fall through the net are now being left. We’ve got to take these patients on. And this [course] gives you the tools to do it.
