The aim was to investigate the effects of a conventional and an unconventional fast food meal on postprandial metabolism in normal- and in overweight subjects.
Methods: Twenty-five healthy volunteers (21-39yrs) participated in this randomized, dietary cross-over study and received two test meals (matched in energy and energy giving nutrients) after an overnight fast with one week between test days. The conventional fast food meal was a hamburger meal (hamburger, bacon, cola drink), the unconventional fast food was a salmonburger meal (fiber rich sourdough ryebread, salat with vinegar, orange juice). Blood samples were taken before the meal and several times after and analyzed for glucose, insulin, blood lipids and high sensitive c-reactive protein (hsCRP).
Results: Postprandial increases in glucose and insulin were 44% lower after the unconventional meal (P0.001 and P=0.003, respectively). The relative differences between meals were more pronounced in overweight participants than in normal weight participants. Postprandial changes in blood lipids and hsCRP were small and not different between meals.
Conclusion: Unconventional fast food which contains rye sourdough bread, salmon, vineagar and vegetables, has around 44% less effect on blood insulin and glucose prostprandially compared to conventional fast food matched in energy and energy giving nutrients. The relative differences between meals are more pronounced in overweight and obese participants as compared to normal weight participants. Thus, a conscious choice might help to control postprandial increases in blood glucose and -insulin.
