Bouhlal and co workers reported that salt had an impact on intake but fat did not. They found that in general food intake increased with salt level, noting that compared with the 'normal' salt levels, a suppression of salt induced a 25 per cent decrease in green bean intake, whereas an addition of salt induced a 15 per cent increase in pasta intake. Contrarily to initial beliefs, the researchers observed no increase in food intake with increasing added sugar level. They said the findings indicate that two to three year old children's food intake may not be affected by its added sugar content.
The study data also showed that preschool children with a higher BMI score consumed more pasta when fat level was higher. The authors said this finding may confirm previous results which highlight fatter children prefer high-fat foods. The researcher said their results imply that fat and sugar addition could be avoided in foods for children without having an impact on palatability, allowing the energy density of children's diet to be limited.
“Furthermore, these findings suggest that there is no need to add salt to pasta which is consumed anyway. On the contrary, salt suppression in vegetables, whose intake is to be promoted, should be considered cautiously,” they said.
