Ihab is a Registered Nutritionist (Public Health) who has expertise in planning, implementing and evaluating sustainable nutrition-sensitive intervention programmes at population level. Ihab has developed an independent academic research career that underpins the pivotal role of nutrition science in modulating complications of global chronic diseases through tailored functional recipes (TFRs). These innovative TFRs are optimised using locally produced food ingredients which are formulated into meals to nourish vulnerable populations and ascertain their optimum health. 

Dr Tewfik is the Programme Leader Human Nutrition (UG-programe), Division of Food, Nutrition and Public Health, University of Westminster. In addition to his PhD from London SouthBank University, Ihab holds Master of Public Health (MPH) and Doctorate of Public Health (DrPH) in Nutrition Department, University of Alexandria. 

Dr Tewfik’s research theme: “Local Food for Global Health”. The ultimate strategy of this research theme is to optimise tailored functional recipes (TFRs) / model meals to modulate global chronic disease. These functional food recipes are not limited to the elimination of undernutrition (macronutrient) but extend to the design and engineering of food that transcends disease prevention by improving availability of micronutrients, increasing biological functions and promoting sustainable health.

These TFRs draw from the growing evidence-based science linking diet to disease epidemiology and links it to ethnobotany, consumer specific dietary preferences and advances in food technology to develop model meals that seek to attenuate/manage a variety of public health concerns.

Ihab's research team has invented and optimised a range of nutrition-sensitive interventions as means to: 

1. Prevent disease, e.g. Ghana project (2013-17):  In Ghana, our public health nutrition strategy targeted ‘Ghana schools feeding programme’ as channel for improving future generation in Ghana. The S-Cool meals which were based on the TFR concept, aimed to develop functional foods recipes for school feeding programmes by employing indigenous food processing methods to improve bioavailability/bioactivity of micronutrients from local agricultural produce without compromising palatability. This nutrition sensitive approach has significantly improved the nutrition status of the school children in Ghana and is considered as viable alternative for ensuring food security and balanced/appropriate nutrition intervention that is well qualified for the long-term strategy.  

2. Modulating and improving the quality of life of terminally ill patients such as those with end stage cancer, e.g. India project (2012-16): In India, we applied the TFR concept to enhance quality of life in advanced cancer patients receiving comprehensive palliative care. We have developed iATTA meal which when combined with tailored nutrition counselling has significantly improved quality of life and stabilise body fat in female cancer cachexia patients receiving comprehensive palliative treatment.

3. Disease management as in the case of HIV/AIDSe.g. Nigeria project (2011-present): In Nigeria, we examined the concept of Tailored Functional Recipe (TFR) to delay the progression of HIV to AIDS. We have developed the Amtewa meal. With adequate physical activity level, Ametwa meal boosted individual’s immune system and sustained optimal quality of life among people living with HIV.

During his 6-month sabbatical (Jan-June2017) at Harvard School of Public Health, Department of Global Health and Population at GHP-HSPH, Ihab has identified and drafted research proposals with scientific team at GHP-HSPH on the following points:

1. To develop the ‘Sustainability Plan’ of the HIV/AIDS public health nutrition intervention in Nigeria.            

2. To formalise and develop the feasibility study for the dissemination of a HIV meal to enhance the immune system of People Living with HIV in Monkole Hospital, Kinshasa, Democratic Republic of Congo.            

In addition to publishing key joint-research outputs as starting point of long-term research team-building.            

 

Ihab’s other research focuses included:

The relationship between the obesogenic environment and health outcomes of individual and population. His work embraces the effects of nutritional exposure during childhood and risk factors for later non-communicable diseases (NCDs) especially in developing countries experiencing economic and nutritional transition. Ihab’s research includes population interventions to improve opportunity for health during early life, and methods for the scaling-up intervention programmes to achieve community level impact. 

Ihab has also collaborated with the American University in Beirut (AUB) through a public health nutritional intervention which aimed to assess the effectiveness of public health nutrition intervention designed to enhance healthy eating and life style modification among Lebanese Polycystic ovary syndrome (PCOs). This intervention has significantly raised patients' nutritional awareness, and enhanced their healthy lifestyle which was reflected by weight reduction and resumption of their reproductive function.

As Fellow of the Royal Society of Public Health (FRSPH), Ihab has been at the forefront of promoting Global public health intervention programmes and in particular among vulnerable group. Ihab’s international research agenda expanded to 11 research projects with UNICEF-UN in aspects of public health nutrition intervention. Nationally, he has carried out three Food Standards Agency (FSA) projects on food safety and one on Biomarkers for predicting breast radiotherapy induced side-effect funded by the National Cancer Research Institute – UK. Ihab has published extensively in international peer reviewed journals (so far over 56 publications). Ihab has worked as international consultant to support capacity building for healthcare workforces in developing countries and has participated in training activities in Africa and Asia.  He is a regular invited speaker on several workshops, CPD and short-training courses and he is key team member to develop international public health education programmes to communicate relevant competencies. Ihab is collaborating with many universities in UK, EU, Middle East. Asia and Africa, on aspects related to knowledge exchange and public health nutrition intervention programmes that employ dietary diversification and behavioral modification approaches. Between 1992 and 2010 he was instrumental in developing the public health nutrition programme at the University of Alexandria, where he fulfilled Associate Professorship at the department of Nutrition.

Editorial-ship: Ihab is currently serving on a number of editorial boards of international renowned scientific journal, he is also the Editor-in-Chief of the International Journal of Food, Nutrition and Public Health – UK.
