Overview

As part of our transition to sustainable healthy diets, there is increasing emphasis to diversify dietary protein intakes with greater consumption of plant based proteins encouraged rather than animal sources. Much emphasis has been placed on potential nutritional considerations, however, the potential for inadvertent food safety risks arises. This PhD will examine the potential for such risks following increased consumption of plant based diets.

We need to transform our current food system if we are to feed the rapidly expanding global population whilst maintaining planetary health. More specifically, there is an urgent need to diversify the foods that currently contribute to our populations’ dietary intakes, particularly for protein. Much focus has centred upon the impact of implementing a protein transition, whether through dietary modelling studies or single randomised controlled trials. However, the focus is predominately on environmental and/or nutritional outcomes rather than considerations relating to food safety. The ongoing DAERA/DAFM funded-projects ‘Protein-I’ and ‘SuHe’ are, respectively, examining the impacts of diversifying dietary protein intakes using a food systems approach (Protein I) and of adopting more Sustainable Healthy Eating Dietary Guidelines (SuHe). In parallel, Mycotox-I (DAFM/DAERA funded) is examining the potential of dietary exposure of mycotoxins in cereals, specifically oats. However, potential trade-offs with respect to intakes of chemicals present in food (either added intentionally or present as contaminants) following such dietary change is unknown. The present PhD will build on the collaborations and data gathered within Protein-I, SuHe and Mycotox-I and will utilise national food consumption databases to examine if there are trade-offs with respect to intakes of such chemicals. Following a thorough literature search to identify candidate chemicals, and in consultation with key policy makers, a series of exposure assessments and dietary modelling will be completed to examine the potential impacts of such a shift in total dietary intakes in target food chemicals and for key population groups e.g. children. Examples of candidate food chemicals could include use of food additives in plant based meat or dairy alternatives, or toxins such as mycotoxins potentially present in cereal products or anti-nutrients. The impact of such a shift on total dietary intakes and in comparison to relevant health based guidance values will be assessed.

The overall PhD aims to align with, and build upon ongoing funded projects focusing on nutritional and/or environmental outcomes to also consider food chemical considerations of relevance to policy makers and regulators.

Skills/experience required: 2.1 or higher primary degree in relevant area (e.g. Nutrition, Biomedical Science, Human Biology). Good mathematical skills. Experience in dietary assessment methods and/or dataset management would be an advantage but not essential.
