A bit about me...

I have been delivering expert, evidence-based nutritional advice for over 15 years. I work with both individuals and the food industry. I have supported businesses such as North Yorkshire County Council, Compass Group and PepsiCo; and helped individuals with issues as diverse as behaviour based nutrition and weight management to fertility and menopause support.

I have a special interest in the microbiome and nutrigenomics; two areas that I feel will revolutionise the way we eat for health in the next decade.

I have a Bachelor of Science degree in Clinical Nutrition, a certificate in Nutrigenomics from the Dieticians of Canada, I am a Registered Nutrition Professional for the Early Years Nutrition Partnership and a Registered Nutritionist with the Association for Nutrition (RNutr). The Association for Nutrition holds the only register of qualified nutritionists recognised by Public Health England, NHS Choices and NHS Careers.

Personally, my passions are (roughly in this order, but that can change depending on my mood!) my family, my friends, my dog, nature and fitness. I also get a real buzz out of helping folk to become the best versions of themselves by making better choices about food and nutrition.

A qualified nutritionist

If you are looking for a qualified nutritionist, always check they have the quality mark post-nominal letters RNutr or ANutr after their name.  These letters can only be used by nutritionists on the UK voluntary Register of Nutritionists (UKVRN), which is upheld by the Association for Nutrition, and is the ONLY register of qualified nutritionists recognised by Public Health England, NHS Choices and NHS Careers.

Nutritionists with the letters RNutr or ANutr have met the rigorously applied standards for scientifically sound evidence-based nutrition and its use in practice.
