A new study looks at how salt sneaks into our snacks, and how much of an impact it has on our lives.

A new study published in the journal Nutrients examined how the contribution of snack foods to sodium intake has changed between 1977 and 2014. The largest increase in sodium intake from snacks was seen in the lowest income group and the lowest education group. Adults and children in the lowest income group went from the lowest sodium intake from snacks to the highest from 1977 to 2014. Salty snack more than doubled during the study period in U.S. adults and increased by 75% in children. Twenty-five percent of sodium intake from snack foods came from grain-based desserts and salty snacks in 2014, with Non-Hispanic Blacks consuming a higher intake of sodium from snacks than other race-ethnic groups. The study found an overall increase in sodium intake from snacking between 1977 and 2014, but noted a declining trend in sodium intake from snacking between the 2003-2006 to 2011-2014 survey periods. The authors noted that their findings have implications for future policy interventions targeting specific demographic subgroups of the US population.
