Abstract: A food storage and nutrition management system including a primary container having which defines a volume for storing a plurality of secondary containers smaller than the primary container. The secondary containers store food items and include a bottom side and an upper rim and are sized and configured such that when placed in the primary container, the upper rims of the secondary containers are substantially co-planar. A container lid sealing closes the primary container and includes a resilient gasket on its underside. Lids are also provided for the secondary containers when used outside the primary container. The gasket is configured to engage the upper rims of the secondary containers regardless of the configuration in which the secondary containers are placed in the primary container. The gasket partially compresses at the upper rims of the secondary containers to form a substantially air tight seal between each of the secondary containers.
