ABSTRACT
Such observations would be quite dif cult to make in the human species-not only because assessments during the whole life span to con rm or not such conclusions cannot be realized, but also because humans are genetically very different; it would not be possible to change only one condition in a completely homogeneous group during a longer lifespan. Conclusions from an experimental model using laboratory animals cannot be transferred to humans, but they at least provide a stimulus and orientation with regard to the possible biological consequences of early dietary manipulations later in life.
