Introduction
In the UK, there is a threefold higher incidence of type 2 diabetes in UK African and Caribbean (AfC) communities, compared to the general population. And ethnic inequalities in type 2 diabetes treatment and outcomes have been documented. And so addressing these inequalities is an urgent healthcare priority in the UK.
Differences in outcomes relate to physiological differences as well as pragmatic issues and structural barriers. Professor Louise Goff has done pioneering work in relation to both aspects.
Prof. Goff’s research has highlighted ethnic differences in type 2 diabetes pathophysiology between those in UK African and Caribbean groups and white Europeans. This means that typical screening for diabetes may not be as useful for AfC communities, in addition to treatments not being as appropriate.
In addition, there are noted differences in engagement with diabetes education services and self-management advice. This may be due to the fact that the delivery of information is not culturally relevant to those in AfC communities. And so diabetes structured education programs have been found to be less successful in people from minority ethnic groups.
Prof. Goff has attempted to address this by developing a culturally tailored self-management education and support program for type 2 diabetes in black-British adults. This program, called the Healthy Eating and Active Lifestyles for Diabetes (HEAL-D) program, has initially been trialed with local Black African and Caribbean communities and healthcare providers in South London.
In this episode, Prof. Goff discusses the ethnic differences in diabetes pathophysiology and the other factors underlying the inequalities in diabetes outcomes in black African and Caribbean communities.

Prof. Goff is an academic dietitian leading an inter-disciplinary programme of research focused on tackling ethnic inequalities in type 2 diabetes.
She has worked extensively with UK African and Caribbean communities spanning a broad range of research, from understanding ethnic differences in the biological mechanisms by which diabetes develops in African and Caribbean groups, through to improving cultural competency of healthcare professionals.
Prof. Goff has developed the Healthy Eating & Active Lifestyles for Diabetes (‘HEAL-D’) programme of research, looking at the feasibility of a culturally tailored diabetes self-management education and support programme for adults of African and Caribbean heritage.
Based on the success of the pilot trial research, Prof. Goff has been funded to conduct a 4-year multicentre randomised controlled trial evaluation of HEAL-D. The trial will begin in August 2023 and run in London, Manchester and Birmingham.
In addition to this, Prof. Goff is also continuing to actively investigate ethnic distinctions in the pathophysiology of type 2 diabetes in people of African heritage. This work uses highly sophisticated methods to assess beta-cell function, tissue-specific sites of insulin resistance and magnetic resonance imaging and spectroscopy to investigate ectopic fat deposition.

#180: Jason Gill, PhD – Role of Ethnicity in Cardio-Metabolic Disease Risk
- University of Glasgow researcher Dr. Jason Gill discusses some of his work looking at differences in adequate physical activity levels, fitness and BMI targets for different ethnic groups, and how this influences diabetes and other cardio-metabolic disease risk.
- His research has looked at why certain population groups (particularly South Asians) appear to be particularly susceptible to the adverse effects of a `Westernizedʼ lifestyle, and how lifestyle interventions can modulate this excess risk.

#405: Adrian Brown, PhD – Dietary Strategies in Type 2 Diabetes
- Dr Adrian Brown is a NIHR Lecturer and Research Fellow in the Centre of Obesity Research at University College London.
- In this episode we discussed the factors that influence the ability to be able to achieve remission and which dietary interventions can potentially achieve remission. You can find this episode here.
#331: Prof. Roy Taylor – Diabetes Remission, Very-low Calorie Diets & the Twin Cycle Hypothesis
- Roy Taylor is Professor of Medicine and Metabolism at the University of Newcastle in the UK.
- Since publishing his “twin cycle” hypothesis of type 2 diabetes in 2008, Prof. Taylor has published several fascinating studies with potentially large implications for the potential to put diabetes into remission;the Counterpoint Study, the Counterbalance study and the DiRECT study. All of which are discussed in this episode. You can find this episode here.

- In this episode, we discussed a range of big questions including:
- Type 2 diabetes as a progressive disease
- Relationship between insulin resistance and decline in beta-cell function
- Can type 2 diabetes be reversed? Remission vs. reversal
