Can you eat your way to living longer?
Kathryn's guest Luigi Fontana can provide some crucial insights into which foods can help prevent age-related diseases.
He's a professor of medicine and nutrition who's based at the University of Sydney and is recognised as a leading expert on longevity.
He's written three books: First - The Path to Longevity: How to reach 100 with the health and stamina of a 40-year old; then the Manual of Health Longevity and Wellbeing: A Three-Step Plan.
His latest is Plant Power: The Essential Plant Food Guide to Enrich Your Health.
It's aimed, he says, at answering some of the most common questions he gets from people he knows - what should they be eating to maximise their health?
As well as explaining the science behind plant-based food benefits, and advice on incorporating it into your diet - it's also chock-full of recipes.
