The Lancet 2012


"Tina is one of our most valued speakers in the Life Advice programme at LEH. She is hugely knowledgeable and highly approachable, and our pupils find her talks practical and positive, crammed full as they are of useful information and suggestions. Tina's mission is to help our teenagers to understand the importance of nutrition and the crucial role it plays in their cognition and well-being and, as a teacher and mother, I can think of no more important lesson, particularly during adolescence and in examination seasons".

“Tina has been working with Emanuel for a number of years, her talks are invaluable to our school pupils. Nutrition remains an important and relevant topic for young people. They have so many questions and are enthusiastic to learn and understand about the importance of nutrition in fuelling the bodies and brains and enabling them to live a happy and healthy lifestyle. Tina’s presentations are fantastic, she has excellent subject knowledge and delivers this is in a sensitive and relatable way for pupils. She creates an environment in which pupils feel safe to ask sensitive questions and pupils have thoroughly enjoyed trying out her recipes and smoothies before exams. I can also recommend her books, they are a must have for any school library or teenage gift.”

Laura Fitzgibbon, PSHE, Emanuel School

“The Nutrition Guru has been a regular visitor to Epsom College over the last 7 years, providing sensible, sane advice; easy to follow and not too radical in terms of encouraging young people (and teachers!) to make informed choices about their eating habits. There’s no finger-wagging nor shaming when offering a balanced approach to healthy living and matching it to the busy lifestyles we all lead makes it feel real, relatable, and doable no matter what age group they address. We would wholeheartedly recommend the company to speak at your school, coupled with top quality, eye-catching resources to be used in lessons or as posters and hand-outs and her book Eat Well and Feel Great - the Teenager’s Guide to Nutrition & Health”.

Helen Keevil Head of PSHE


Diet and nutrition can give the competitive edge in both academic and sporting performance

In an ever growing competitive environment where see so many young people and children struggling at school, research shows that diet and lifestyle can influence every aspect of a child's and can truly make the biggest difference to their;
