Downloads From King Arthur to Indiana Jones, tales of the hunt for the Holy Grail are legion. The mystical artefact, which made its first appearance in a late 12th century poem by Chrétien de Troyes and which Robert de Boron subsequently claimed was Jesus Christ’s drinking vessel from the Last Supper, has since made countless appearances in literature, art, music, TV shows, movies and even video games. But it continues to prove elusive – much like the most sought after treasure of the food world, the ultimate healthy snack. Indeed, the Holy Grail of snacking – a product that doesn’t pile on the pounds, boosts wellbeing, keeps you fuller for longer and delivers on indulgence – has turned into something of a quest for suppliers.

From April 2022, those items will face strict advertising restrictions under plans confirmed in the Queen’s Speech this week.
