Diet sodas drag down US soda's performance; Pepsi takes back No. 2 spot from Diet Coke

Americans bought less soda for the tenth straight year in 2014, with diet sodas shrinking more than their sugary counterparts, according to a report released Thursday.

An annual report by the industry tracker Beverage Digest found that overall soda volume slipped 0.9 percent last year, moderating from the decline of 3 percent the previous year.

And the poor performance of diet sodas in particular led to a shake-up in the top 10 U.S. soda rankings; even though people bought less Pepsi, it managed to regain the No. 2 spot from Diet Coke, which suffered an even steeper decline. Diet Coke had knocked Pepsi off the No. 2 spot in 2010.

Coke remained by far the most popular soda in the U.S.
