The energy density of foods is largely determined by their water
and fat contents (Drewnowski, 1998). In our study, fat- and/or
sugar-reduced biscuits did not exceed a 5% energy density reduction,
except for C Biscuits in which the percentages of reduction of
energy density ranged from 6% for the (S-) to 19% for the (FS)
variant (Table 1). This moderate impact on energy density emphasises
that efforts to reduce sugar and fat content made by the food
industry are limited. Thus, these efforts must be followed by
numerous industries and on several different products to succeed
in reducing the mean energy density of the diet of the entire
population.
