    A customer packs groceries into his car outside of a Costco store on March 6, 2014 in Richmond, California.

    Shoppers who opt for warehouse clubs like Costco and Walmart over traditional grocery stores are buying food with more fat, sugar and sodium, according to a new study.

    People are turning to mass-merchandise retailers to buy their food along with other essentially bulk items like a 30-pack of toilet paper and clothes, according to the American Journal of Preventative Medicine study published this week.

    Packaged foods at these wholesale retailers are usually filled with more calories, sugar, sodium and saturated fats than packaged foods from grocery stores, the study found.
