Impact of a transition to diets from sustainable sources on micronutrient intakes and status
type: CreativeWork
description: Background: A global transition to diets from sustainable sources is required for planetary health. This transition will result in greater reliance on plant-based protein sources coupled with reductions in animal source foods. The evidence base underpinning the formulation of nutrition policy lacks data on the feasibility, safety and effectiveness of translating sustainable dietary guidelines into practice in the population, which could pose risks to nutrition for large sectors, including females of reproductive age and children. Objective: The aim of this thesis was to explore of the impact of a transition to diets from sustainable sources on micronutrient (MN) intakes and status. Objectives were to systematically review the existing evidence assessing the impact of following environmentally protective diets on MN intakes and status (Chapter 2); design and conduct a first-of-its-kind dietary intervention trial of an environmentally protective diet (Chapter 3); assess the impact of the intervention on MN intakes (Chapter 4) and status (Chapter 5); and explore the potential for dietary modelling to assist the development of MN adequate diets from sustainable sources (Chapter 6). Methods: PRISMA guidelines were followed to conduct a systematic literature review (SLR) of studies reporting MN and environmental outcomes, searching seven databases from January 2011 to October 2022 (Chapter 2). Chapters 3 to 5 describe a 12-week, three-centre, single-blind, parallel, randomised controlled trial (RCT) among 355 healthy participants aged 18-64 years, known as MyPlanetDiet. The intervention provided participants with personalised dietary advice based on their dietary habits, in line with sustainable healthy principles (intervention arm) or dietary guidance based on the Irish and Northern Irish healthy eating guidelines (control arm). Outcomes included changes in dietary environmental impacts, energy, protein, MN intakes, the prevalence of inadequate intakes and changes in MN …
