Food makers see the snack in everything

There are no meals anymore, only snacks.

As around-the-clock grazing upends the way people eat, companies are reimagining foods that aren't normally seen as snacks to elbow in on the trend. That means everything including grilled chicken, cereal, chocolate, peanut butter and even Spam are now being marketed as snacks.

Some are trying to jump into the party by playing up protein. Meat processing giant Tyson launched Hillshire Snacking this year with packs of cut-up chicken that people are supposed to grab and eat with their hands (120 calories per pack). Canned meat maker Hormel is testing "Spam Snacks," which are dried chunks of the famous meat in re-sealable bags (220 calories per bag).
