Packs of soda spur more consumption
New York city attempted to ban the sale of oversized sugary drinks, but a new study published in the journal PLOS ONE questions how effective that approach may have been be in actually reducing the overall consumption of the calorie-laden beverages.
To gauge how much soda consumers are likely to buy when presented with different size and packaging options, researchers from the University of California, San Diego, presented three different menu options to 100 undergraduate students. The first menu offered 16, 24, or 32 ounce sized individual drinks with a meal. The second offered a 16 oz. drink, bundles of two 12 oz. drinks or two 16 oz. drinks with a meal. The third menu offered only individual 16 oz. drinks with a meal.
When the volunteers made their selections, researchers found that more soda was purchased and consumed from the menu that offered packs of 12 oz. or 16 oz. drinks than from the menu that offered individual sodas of different sizes.
This research suggests banning large-sized sodas may inadvertently prompt people to consume more soda than before.
