More than 14million meals are expected to be served during the Games across 40 locations.

The food on offer to visitors will fit into two main themes - British and international.

British food will reflect the multicultural mix of flavours and foods enjoyed across the country, and regional products will be celebrated, including sourdough bread from Tower Hamlets made in a traditional brick oven lined with peat from the Thames.

There will also be a range of international dishes on offer.

The London Organising Committee of the Olympic and Paralympic Games (LOCOG) said there would be a focus on affordability, with food and drinks for a family of four costing under £40.

In line with London 2012’s sustainability commitments, all fruit, vegetables and cereals are Red Tractor accredited, British and seasonal where available.

All dairy, beef, lamb, pork and poultry is also Red Tractor accredited as a minimum.

Bananas, tea, coffee, sugar and white and rose wine are Fairtrade or ethically sourced and traditional cheeses are British. Eggs are British Lion mark free range and all chocolate sold is Fairtrade or ethically sourced.

London 2012 commercial partners Coca-Cola, McDonald’s, Cadbury Nature Valley and Heineken will also be supplying food and drink and will provide the only branded products on sale.

London 2012 also aims to become the first ever Zero Waste Games. LOCOG has partnered with the Waste and Resources Action Programme (WRAP) to improve packaging and recycling and during the Games event waste from public areas will be channelled into three waste streams - recycling; food and compostable packaging; non-recyclables.

LOCOG chief executive Paul Deighton said: “We want everyone who attends the Games this summer to have a fantastic experience and central to this is the food and drink that’s available.

“We have gone to great lengths to find top quality, tasty food that celebrates the best of Britain. We believe that our prices are more than comparable to those found at other major sporting events which because of their temporary nature are often more expensive than the high street.

“We are proud that the catering and industry has been quick to adopt the standards of our Food Vision, leaving a stronger and sustainable industry as a legacy of the Games.”

LOCOG is also responsible for feeding more than 15,000 athletes across both the Olympic and Paralympic Games. Over the course of the Games they will be served 1.2million meals, comprising of 1,300 different types of dishes.

On the busiest day, more than 65,000 meals will be served to athletes.

The main dining room seats more than 5,000 athletes and consists of four zones including British, European, Mediterranean, African and Caribbean dishes and caters for special diets such as halal, kosher, low salt and allergens.
