Available energy from soft drinks: more than the sum of its parts.
OBJECTIVE
To evaluate the relationship between energy available from sugar-sweetened beverages (SSB) and total energy availability.


METHODS
Ecological study using food availability data from 1976 to 2007 from the database of the Canadian Socio-Economic Information Management System. The average available total daily energy per capita (kJ (kcal)/d per capita) and percentage of energy from SSB (%E/d per capita) were calculated. A regression analysis was performed with average available total daily energy per capita (kJ (kcal)/d per capita) as the outcome and percentage of energy from SSB as the independent variable (%E/d per capita).


METHODS
Canada 1976-2007.


METHODS
None.


RESULTS
Between 1976 and 2007, total available energy increased on average by 669 kJ (160 kcal)/d per capita, and energy from SSB by 155 kJ (37 kcal)/d per capita. Total available energy increased by 434 kJ (104 kcal)/d per capita for a one unit increase in average percentage of energy from SSB.


CONCLUSIONS
Total available energy increased as the contribution of energy available from SSB increased. This increase was larger than that explained by energy availability from SSB alone. Reducing energy from soft drinks may contribute to larger reductions in total energy available for consumption.
