Dr Marisol Warthon Medina
RNutr (Public Health), PhD in Nutritional Sciences
Research Fellow, UK/Peru
Marisol is a committed nutritionist, initially with interest in animal nutrition in her home country of Peru where she qualified as a Vet. She has been involved in nutrition in one form or another all of her life, with her family's business in Peru being the development and sale of animal food products. She has developed her career in human nutrition since arriving in the UK, presented at conferences in the UK and Europe, with several published papers to her name. She has taken her qualifications in human nutrition to doctorate level, completing her PhD in October 2014. She has worked in Latin America and Europe.

Marisol is particularly interested in micronutrients, especially zinc, which she studied in depth in her PhD thesis, and continued this with her coordination role on the Zinc-Net COST group project. She was overall coordinator for this project between 2014 and 2016. She has been an active member of the Zinc UK special interest group since 2009.
She is interested in public health nutrition and epidemiology, including dietary assessment (part of her BSc dissertation in the elderly, as well as her PhD study, and her recent work at the University of Leeds to develop improved dietary assessment technology), food portion sizes and the link to obesity and diabetes. As part of this she is interested in the application of the adequate diet according to the energy requirement at each stage of human life hence her research in disadvantaged populations at risk of malnutrition across Europe and her PhD empirical study in Peru. She attempts to promote healthy nutrition and lifestyle.
Her interest in nutrition started from her veterinary background of providing and preparing, via software, an adequate diet for each stage of growth in large animals, and from the business of her family in Peru developing and selling animal feeds. Upon arriving in the UK she decided to extend this to studying nutrition in humans.
During her career in the UK, she has developed from being involved purely in the research, to the management of projects, working to get the best out of staff, and coordinating activities so that projects achieve their potential.

From 2018 she is employed at the Quadram Research Institute in Norwich.
Between 2016 and 2018 she was employed at the University of Leeds as a Research Fellow in Nutritional Epidemiology working as Project Manager for the Dietary Assessment Tool Network (DIET@NET) project, funded by the Medical Research Council to improve and innovate in dietary assessment technology. The DIET@NET partnership brings together leading experts in nutritional epidemiology and food composition from 8 UK universities and institutions. The output from this project was the Nutritools website. This website provides best practice guidelines for dietary assessment methods, visibility of the strengths/weaknesses of, and visualisation tools to aid in the selection of, a dietary assessment tool. It also provides the ability to run some dietary assessment tools directly.
Marisol wrote significant parts of the Best Practice Guidelines paper, and coordinated its overall development, as well as publishing it together with related abstracts. She presented work from the Nutritools project at the ISBNPA conference in Canada (2017), and at Instituto de Investigacion Nutricional (IIN) in Peru (2017). She had a secondment to IIN promoting the related nutritional tool myfood24 and establishing links between the organisations (2018). She also spoke at Lund University in Sweden (2018), disseminating information about myfood24 and Nutritools. Finally, she helped to organize the website launch event on the final day of the project, and presented the Best Practice Guidelines and useful links.
Between 2014 and 2016 she worked as Project Coordinator for the Zinc-Net project, funded by COST (European Cooperation in Science and Technology), set up to build a multi-disciplinary platform of all professionals interested in the zinc micronutrient. Her role also involved the organisation of events for the project, such as the November 2014 Zinc-Net meeting in London as well as workshops in Hungary, Turkey, Spain and the Czech Republic. She liaised with researchers at all levels from across Europe and across language barriers, managing the finance of the project, as well as providing end of year financial reports to the COST organisation. In addition, she wrote articles for blogs, for the NHD magazine, and for the EQUATOR network.
Between 2014 and 2015 she performed postdoctoral roles, assisting permanent staff, searching for research funding for research projects, and lecturing.
She completed her PhD in Nutritional Sciences at the University of Central Lancashire (UK). This included performing a study evaluating the impact of micronutrient supplementation during infancy on cognitive and social development in Peruvian pre-school children of lower socio-economical status with reference to zinc and cognition. In order to fulfil this study she developed a research relationship between UCLAN in the UK, and Instituto de Investigacion Nutricional (IIN) in Peru, so as to identify a suitable population, cater for all ethical requirements for Peruvian studies, recruit data collectors, as well as arrange for storage and analysis of blood samples. She subsequently published 2 academic papers relating to this PhD thesis.
Between 2009 and 2012 Marisol worked as a Research Assistant on the EURRECA program (EURopean micronutrient RECommendations Aligned). This program was set up to develop a framework of advice on micronutrients to better inform policy-makers as they formulate precise recommendations in Europe. The EURRECA network was made up of 35 partners in 18 countries within the EU. Marisol's role within this project was to perform data extraction and meta-analysis of selected papers evaluating zinc intake, status and health outcomes for various population groups (adults, elderly, children and adolescents, pregnant/lactating women, and low income migrants), as well as to undertake several systematic reviews.
She wrote and co-authored various papers during this role.
Marisol has a thorough understanding of nutritional composition of foods, with a particular focus on macro and micronutrients, though currently specialising in micronutrients. She also has some experience of psychological testing of cognitive development in children due to her research into the effect of zinc on development in the early years of life. A short overview of (some of) Marisol's skills are shown below
