Amsterdam, Netherlands: Reducing the amount of sugar added to sodas and the size of the packages offered in supermarkets may help us all consume less sugar overall, so lowering the hazards to our health.

Consumers will benefit, but how will manufacturers be impacted? Marketing diet or sugar-free sodas does not result in a rise in the overall turnover of soda producers, according to US research.

This is due to the fact that consumers frequently move between sweet and sugar-free varieties of the same brand. Reducing the size of the soda package does, however, improve the brand's overall sales results. On the basis of data from the US, Jonne Guyt (UvA) and Kristopher Keller (University of North Carolina at Chapel Hill) conducted a recent study in marketing.

Excess sugar consumption is a problem all over the world. It can lead to a number of health issues, including diabetes and cardiovascular disease, resulting in an increased burden on the healthcare system. "Companies like PepsiCo have reduced the sugar content of their products over the years, in addition to marketing their best-known brands in smaller packages ever more frequently. Although this has not reduced the average sugar content, the consumer's sugar intake per product has gone down in absolute terms," Guyt explained.

Soda manufacturers are having to strike a balance between reducing their products' sugar content on the one hand and maintaining or growing their turnover on the other. This can be difficult to achieve if consumers reject less sugary alternatives. Using data from the US, Guyt and Keller investigated whether the sugar content reduction strategies of soda manufacturers had an effect on sales - and if so, under which circumstances.


'While reducing the sugar content of sodas leads to lower sugar consumption, replacing a sugary drink with a new diet or sugar-free version tends not to make a difference to the producer's bottom line', Guyt said, "This is because of brand cannibalisation: the increased sales of the new diet version and the reduced sales of the sugary version of the same drink cancel each other out. Clearly, this is good news for consumers from a health standpoint, but less appealing when it comes to the brands' overall results. They benefit more from selling sugary drinks. However, we found that marketing the new drinks in smaller packages - like what the Americans call 'mini cans' of 7.5 and 8 fl oz (around 240 ml) - does lead to an increase in the brands' overall sales figures. This can be explained by the fact that these packages are as popular among consumers as the larger packages of competing brands that they used to buy. Overall, it is a win-win situation for consumers and producers alike."

'Fun' instead of 'healthy'

Among the other findings was the significant role played by a brand's product strategy. The researchers discovered that sodas with less sugar sold better when they were marketed with an enjoyment claim, such as 'sweetened with sugar', and worse when marketed with a health claim, such as 'no sugar'.

These products also sold better when marketed under the parent brand compared to a subordinate brand. Keller: 'Sugar content reduction efforts are noticeably more effective when not too much attention is drawn to them. Coca-Cola's Zero Sugar product range is a good example of this. In 2021, the range was redesigned to make it look more like "regular" Coca-Cola, as opposed to the Coca-Cola Zero of before.' Smaller packages also work better when marketed as a fun, high-quality alternative instead of a healthier one. Sales figures increase even further when smaller packages are sold as single products rather than as part of a multi-pack.

Not as mini as it sounds

Guyt and Keller analysed sales figures for almost 130,000 newly launched sodas produced by around 80 brands and sold in US supermarkets over a period of 11 years. They enriched the data with information about the sugar content of the various sodas. In addition, they looked at the brands' product strategies: labelling (enjoyment or health claim), branding (parent or subsidiary brand) and packaging format (single product or multi-pack).
