Increased SSB consumption world-wide can be attributed to successful
marketing, low cost, increased portion sizes, and high availability.
To induce sales and impulse purchases, retail establishments use price
discounts and locate products in check-out aisles, in ‘special displays’,
and at the end of aisles.
The price of SSBs has not kept up with inflation, for decades
remaining consistently below the consumer price index.Low-income
households purchase more SSBs and at lower prices than higher-income
households.And SSBs cost less in relation to other goods in
developing countries than in industrial countries.
