Professor John Nolan recently joined Karl Henry on The Real Health Podcast to discuss the important connection between nutrition, eye health and brain health.

During the conversation, John explored the role of carotenoids and the importance of colourful foods in supporting long-term health, as well as how targeted nutrition may help support vision and cognitive function as we age.

John also spoke about his new documentary, A Vision for Vision, which follows more than 20 years of research into the relationship between nutrition, vision and brain health.

The conversation also covered what consumers should consider when choosing supplements, including the importance of scientific evidence, product quality and independent batch testing.
