James Gallagher reports from the UK, one of the wealthiest countries in the world, where food prices are rising at the fastest rate for 45 years and millions are turning to charity to feed themselves and their families.

He visits the charities which help people to continue to eat and cook healthy food and hears from Professor Sir Michael Marmot from University College London, who has spent a lifetime researching the consequences of inequality and poverty. Food insecurity, he tells James, damages the health of children and adults.
