Along with a sandwich, a piece of fruit and a packet of crisps, it has for decades been a staple in children's lunchboxes.
But over the past year cheesy triangles and Babybels are surging in popularity among adults seeking out healthy snacks which do not contain high levels of sugar.
Over the same period volume sales of sweet biscuits have fallen slightly, industry data shows.
According to the Grocer magazine snack cheeses have for the first time evolved from a children's traditional lunchbox staple to an established adult snack.
Data from analysts at Kantar Worldpanel show sales of mini portions of cheese are up £9.2 million in value this year, with volumes up 7.2 per cent.
It is a major turnaround compared to 2017 when the future of the sector looked bleak, losing a hefty 49 million snacking occasions.
2018 has also been a strong year for cheese overall, with value sales up 3.7 per cent, adding a total of £104.1 million to the £2.88 billion category.
It comes as the UK's most popular cheese brands Babybel and Laughing Cow have been actively targeting adults this year through celebrities and social media influences like Scarlett Moffatt and Stacey Soloman.
Gaelle Vernet, group brand manager at Bel UK, which owns Babybel and Laughing Cow, said "Consumers are looking for lower sugar snacks but they don't want to compromise on taste.
"Cheese is benefiting from consumers seeking out healthy snacking options with 54 per cent associating cheese with being a source of calcium and 38 per cent regarding it as a good source of protein."
