About this event

  • Date and time Mon 13 May 2024 from 6:00pm to 8:15pm
  • Location Royal Society of Medicine
  • Organised by Public Engagement Programme, The Howard Foundation

Join us for the 2024 Howard Foundation lecture, focusing on age-related macular degeneration and dementia. The lecture will be delivered by Professor John Nolan, Howard Chair in Human Nutrition and Director of the Nutrition Research Centre Ireland. Following the lecture, you are invited to join us for a reception to network, relax, and enjoy a refreshing drink in the RSMs iconic glass atrium.   

Age-related macular degeneration (AMD) is a multifactorial disease of the retina characterised by a spectrum of degenerative changes at the macula, ultimately leading to central vision impairment. Alzheimer’s disease is also a complex multifactorial neurodegenerative disease resulting in abnormalities in cognition, behaviour and day-to-day function. Given the growing and ageing world population, the number of people living with AMD and Alzheimer’s disease continues to rise worldwide. The aetiopathogenesis of these conditions involves oxidative-stress-induced inflammation at the retina and brain, respectively.  

Carotenoids are a group of over 700 naturally occurring nutritional pigments, synthesised by plants, algae, and photosynthetic bacteria. Humans consume circa 50 carotenoids from diet, and only 20 have been identified in the human body (in blood, and fatty tissues and organs, e.g. retina and brain). 

Exponential increases in the prevalence of AMD and Alzheimer’s disease, combined with limited treatment options for both conditions, are driving the need for interventions to ameliorate symptoms and improve the quality of life in patients living with these conditions. 

In this lecture, Professor Nolan will explain how targeted and safe nutritional supplementation of the eye and brain, offers a holistic management option for AMD and Alzheimer’s disease. Moreover, this lecture will underline the need for early intervention using these nutritional formulations, to enhance the health and quality of life of the general population, while preventing the onset of these life-destroying age-related diseases of the eye and brain. 

By attending, you will:

  • Appreciate the extent of age-related macular degeneration and dementia across the UK, their consequences and costs
  • Gain an overview of the nature of carotenoids, their sources in nature and foods for humans and their biological role
  • Understand variation in the distribution of carotenoids and focus on their role in the eye and brain
  • Learn about the experimental evidence for supplementation with carotenoids in macular disease and dementia, the need for further work and next steps in translation into practice
  • Identify the problems with early detection tools: contrast sensitivity and early dementia screening

The RSM would like to thank The Howard Foundation for their support of this event. 

Dr Alan Howard (1929-2020)

Born in Norwich in 1929, Alan Howard won a scholarship to Downing College Cambridge in 1948, gaining his MA and PhD in 1955. He spent over 70 years connected with Downing as a student, researcher, teacher, and benefactor. 

Dr Howard became a leading scientist in the fields of atherosclerosis, obesity and, latterly, nutrition. He published extensively, was a writer and editor of books and journals, and organiser of international conferences. 

He is most widely known as the inventor of a very low-calorie diet, known as the Cambridge Diet; the result of many years of research and clinical trials in the 1960s and 1970s. This became a patented formula that sold widely in America and Europe in the 1980s and continues to flourish today through the company he founded, now known as Cambridge Weightplan. 

For the final 20 years of his life, Dr Howard led research into the role of macular carotenoids on vision and memory, latterly working with the Waterford Institute of Technology in Ireland. 

In 1982 he created an English charitable trust, the Howard Foundation, which has supported an annual lecture at the Royal Society of Medicine and numerous scientific research projects. The Foundation has also donated generously to Downing College, enabling the construction of three buildings including a magnificent neoclassical theatre. His son Jon, and daughter Julie, lawyer and dietitian respectively, continue to run the Howard Foundation alongside two other Trustees. 

Dr Howard died aged 91 in June 2020. His legacy continues with both the work of the Howard Foundation and BON, the Brain and Optical Nutrition network of scientists.

Speaker's biography

Professor John Nolan has dedicated his career to understanding the impact of nutrition on eye and brain health. Hailing from Carrick-on-Suir, Ireland, his journey began with a science degree at Waterford Institute of Technology, followed by a PhD and a Fulbright Scholarship at the Medical College of Georgia.


Returning to Ireland, Professor Nolan established the Macular Pigment Research Group, spending 18 years unlocking the secrets of nutritional pigments for eye health. His ground-breaking work led to the discovery that meso-zeaxanthin, combined with lutein and zeaxanthin, could enhance vision and potentially offer protection against age-related macular degeneration, a leading cause of blindness. This crucial finding was further solidified by the Central Retinal Enrichment Supplementation Trials (CREST), funded by the prestigious European Research Council Starting Grant.


Driven by a desire to expand his impact, Professor Nolan founded the Nutrition Research Centre Ireland, in 2016. This multidisciplinary team delves into the link between nutrition, lifestyle, and human well-being, currently focusing on identifying key nutrients for cognitive function and brain health. Their ultimate goal? Reducing the risk of Alzheimer's disease.
