Despite issues like obesity, the recession and time-strapped lifestyles, Americans are purchasing less portion-controlled packaging, reports Mintel. For instance, just 14% (one in seven) of adults are currently buying pre-measured products. The No. 1 reason for this is convenience, while the No. 2 reason is weight management.

Of the adults that do not buy 100-calorie packs, half say they are just not interested, while a third of people say they prefer measuring out their own food. Another thing keeping consumers away from portion-controlled packs is cost.
