ABSTRACT
All that happens in the maternal organism during pregnancy can have a decisive impact on the future of the child. Many diseases that cause premature death originate during the fetal and infant period (Barker 1990, 1992). Up to now, it has generally been believed that genetic and possibly pathological factors determine most of the characteristics of the offspring. Less attention was paid to natural factors within physiological conditions, namely diet and physical activity during pregnancy and their in uence on the offspring. Experiences from previous historical periods and different societies have importance at present, in spite of the fact that scienti c studies could hardly be conducted previously. At present, they cannot be repeated, because of changes in the environment and way of life.
