In this episode we explore how agricultural systems shape human and planetary health.

We are joined by Professor Amir Kassam, a globally recognised expert in conservation agriculture (CA), whose work has helped advance sustainable farming systems worldwide. Professor Kassam explains the scientific foundations of CA and how it differs from the increasingly popular concept of regenerative agriculture.

Drawing on his contributions to global food systems discussions, including work aligned with the EAT-Lancet Commission, we examine how agriculture must operate within planetary boundaries to safeguard soil, water, biodiversity, climate stability, and ultimately public health.

For healthcare professionals, this episode reframes prevention at a systems level, highlighting agriculture as an upstream determinant of health. If we are serious about sustainable diets and long-term wellbeing, we must also consider how food is grown.

This week on the Nutshell , Daisy and Clare discuss whether paying more for organic produce pays off in terms of health benefits. There are lots of things to think about from pesticide burden to the nutrient values in the foods themselves. But with ever rising food bills, should you prioritise organic, or can we afford not to?

From fears around hormone disruption, thyroid health, breast cancer, fertility, and even feminising effects in men, soy has been surrounded by controversy for many years.

Yet at the same time, populations consuming soy regularly tend to have lower rates of chronic disease and longer life expectancy. So what does the totality of the scientific evidence actually say?

To answer that question we’re joined by Dr Mark Messina, one of the world’s leading researchers on soya foods and health.

Dr Messina is Director of Nutrition Science and Research at the Soy Nutrition Institute (SNI) Global. He has dedicated his career to studying the health effects of soya foods and has published over 125 articles and book chapters over his three decades of work in the field.

In this deep dive we will distinguish the scientific evidence from pervasive online misconceptions and examine what the current research indicates about soya's effects on cardiovascular health, cancer risk, endocrine function, and well being.
