Consumers are being urged to make buying Fairtrade products part of their shopping habit.
Damian Lewis made a film about producers in Bolivia
The Fairtrade Foundation has launched a campaign to build on the 40% increase in sales of Fairtrade goods last year.
Actor Damian Lewis travelled to Bolivia - one of the poorest countries in South America - to see how privatisation has affected producers.
The foundation said people like those the Band of Brothers star met could be helped by more people buying Fairtrade.
The actor travelled to Bolivia with Christian Aid to see for himself the impact of free market economic policies on everyday life.
Bolivia's new president Evo Morales said last week the free-market model does not work in the country, and the partial privatisation of basic services and natural resources should be reversed.
The Fairtrade Foundation said it hoped to see a 50% rise in the coming year on last year's £100m fair food sales in the UK.
The foundation says that around 1,500 Fairtrade products from Africa, the Caribbean, Asia and Latin America are available in UK shops.
But a study by TNS Omnimas for the foundation, found the majority of shoppers tend to stick to old habits when picking produce.
"So many people in the UK are won over by the idea of Fairtrade and want to shop with respect," said Harriet Lamb, Executive Director of the Fairtrade Foundation.
"Our challenge now is to make it easy to get the Fairtrade habit and switch to buying Fairtrade certified goods."
Silver Kasoro-Atwoki, a tea producer from Uganda, said Fairtrade had allowed his company to switch to better agricultural techniques.
"We have opened new access roads to benefit all in the community, assisted in providing primary healthcare through construction of health clinics and added a new block to the local secondary school," he said.
"Fairtrade is significantly contributing towards the social improvement of our community and providing a better future for our youngsters."
Damian Lewis' trip is being shown on the charity channel Community Channel.
