[The effect of energy density and viscosity of porridges on the energy intake of infants].
It has been known for at least 25 years that high energy density and low viscosity are desirable attributes of complementary foods. However, the effects of increasing energy density and reducing viscosity of gruels on infant energy intake have only been studied in the last 10 years. Works published between 1986 and 1992 were carried out with infants randomly selected in urban slums or rural areas in India and Tanzania. When gruels are given in a single meal, all of them showed higher energy intake with both high energy-dense and low viscosity gruels. But these studies do not give information about the effects of these gruels on daily energy intake from gruels and on total daily energy intake when they are given with feeding frequencies corresponding to traditional weaning practices. Works published since 1992 were conducted among infants suffering from or recovering from acute diarrhoea or severe malnutrition. A positive effect of increasing energy density of gruels was observed not only on energy intake from gruels but also on total energy intake. On the other hand, effectiveness of reducing viscosity was not clearly demonstrated. Further studies are required, particularly to identify the conditions for which high energy dense gruels prepared from bulk-reduced starchy staples are able to significantly improve infant energy intake.
