Adrian Chiles talks to Larissa Pelham, Head of Emergency Food Security and Livelihoods for Oxfam, about how charities seek to eradicate malnourishment in the Third World, by working with local food producers.

It's well known that TV and radio presenter Adrian Chiles loves football. What's less well known is his real passion: food, both eating and cooking it. Adrian believes in the power of food to change lives, to improve society and to bring people together.

At this year's Bristol Food Connections festival, he recorded two editions of One to One in front of an audience with guests who have extraordinary life changing food stories to tell.

Larissa Pelham has spent most of her career trying to ensure that all people, at all times, have physical and economic access to sufficient, safe and nutritious food, that's the definition of food security, but she explains the difficulties of doing this in areas of political unrest or natural disaster.

She also discusses with Adrian the effect her work has had on her own attitude to food and eating.
