Entrepreneurial brothers believe they've found the the key to indulging on ice cream without putting on the pounds after they were inspired by wild superfoods in Brazil.

Founder Charlie Thuillier and brother Harry's Oppo ice creams have been picked up by Kensington's flagship Wholefoods and Waitroses across west London after they smashed their crowdfunding target.

"The idea first came when they decided to break the world record for the longest distance travelled by kite buggy unsupported," said a spokesperson for Oppo.

"Whilst out there, they realised that with no previous experience of kite buggies and the nearest airport being miles away, they began to drag their buggies across the sand.

"They quickly ran out of food - Charlie lost 8kg in just two weeks - and had no choice but to try coconuts and other wild foods.

"It was whilst they did this, that they realised indulgent food could be healthy, but still delicious and they decided to give ice cream making a go."

Charlie quit his job in 2012 to found the brand and after months of mishaps, flavour tasting and the occasional triumphant moment, Oppo was launched.

Since then, the company has seen a string of successes which includes reaching the finals of the World Food Innovation Awards for Best New Business.

But after winning Startup of the Year, the brothers were invited to fly with Prime Minister David Cameron to Italy to represent small British businesses and meet the Italian Prime Minister.

"It was a real triumph for them" said marketing manager Plum Turner.

"Using lesser known ingredients such as Baobab, Spirulina and Salted Caramel with Lucuma, it has been such a trial and error process.

"But they have been really open about what they put into their products and that's really important to them and the people who are noticing their ice creams."
