Pulse grower, lupins, vegan nutrition

It can be a challenge to buy British when you're vegan, but Charlotte Smith speaks to Nick Saltmarsh who sources UK-grown beans and pulses. She also finds out about the pros and cons of the vegan diet with Professor Tom Sanders, Emeritus Professor of Nutrition & Dietetics at King's College London.

Simon Roberts from the Ridgeview Wine Estate explains why the humble candle can be the key to a successful vintage, and Sarah Swadling reports on a trial to grow Lupins as an alternative for livestock rations.
