Which is the cream of the crop for your health and the planet?

The supermarket shelves are fairly bulging with plant-based options for people who either prefer not to drink cow's milk or can't for health reasons like an allergy. Some have been around for a while - like soy, almond and the current best-seller in the UK, oat - but there are newer additions to consider like hazelnut, hemp and a drink made from dried peas.

Listener Sian wants to know if these milk alternatives are better for her health and the environment than cow's milk. Do they give you the same nutritional benefits? And what's the carbon footprint of each, and how do they compare to the production of cow's milk?
