healthy choice but are we really? abc s becky worley has the story. reporter: snack, workout fuel or meal replacement. americans spent $1.2 billion on bars last year. i think that it s an easy go-to, especially a mom on the run. i choose them as a snack because they re convenient. reporter: earlier this year the fda told kind bars to stop using the word healthy, because that term s reserved for foods relatively low in fat, but no kind bars have less than 4 grams of fat, and some have 16 grams. so the issue with bars is that, really they are full of sugar, fat and salt. reporter: but really how full? we looked at popular bars and picked two that were more than 200 calories. that s a lot of calories. reporter: then we asked nutritionist maya feller to analyze them. first, the larabar. what s a comparable equivalent snack? so i took this larabar and i looked at the nutrition facts label. i looked at the total fat.
