Study design. This study was conducted as a crossover study. There was a 14-day washout period between intervention periods I and II. During the intervention period, the subjects were asked to ingest the test food every day and to record their living conditions on the Life Questionnaire. For three days prior to each test day, the subjects were asked to take pictures of all their meals with a camera, and in addition they were asked to measure as much food as possible and take pictures of food labels to record their dietary status. On day 14 of each intervention period, a metabolic test was conducted.
