Now the food science technology behind these plant-based foods has come of age with products designed to closely look, feel, taste and even bleed like the real thing.

Gone are the days when cow’s milk was the only choice at the supermarket. There has been an explosion in recent years of plant-based non-dairy alternative milks. From the very familiar soy milk, we now have almond, coconut, oat, and rice milk plus a host of others joining the party. How well these contender alt-milks stack up against the ‘reference standard’ of cow’s milk is what I’ll be digging into in this podcast.

Welcome to the rapidly moving world of nutritional psychiatry which is uncovering the key links between diet and mental health.

In this podcast, I look at the health merits of organic food and unpick those health and nutrition claims.

In this podcast, I’ll look at the roles o...
