Flavoured water brand Nuva is set to kick off a poster campaign in light of the government’s Childhood Obesity Plan.

The month-long push aims to highlight the lack of added sugar and sweeteners in the brand’s products, and comes after the government announced details of its soft drink sugar levy in August.

Featuring a woman ‘showering’ in sugar, the poster’s strapline reads, “Nat doesn’t know how much sugar, sweetener or preservatives are in her drinks. Do you?”

Part of a £525,000 drive, the ad will feature on London buses and will be supported by sampling and social media activity from October.

“Too much sugar can be detrimental to the health of the British people, particularly children, who are consuming far too many hidden sugars. Much of this is coming from the soft drinks we choose,” said Nuva co-founder Gemma Pond.

“Even healthier options such as reduced-sugar drinks can contain the equivalent of five sugar cubes in a small 500ml bottle. Our drinks are completely sugar-free and come in a variety of flavours.”
