  abstract = {{B}ackground {D}uring pregnancy, the diet of a mother-to-be should be adapted to meet increases in nutrient requirements. {W}e analyzed the theoretical efficiency and acceptability of different types of tailored dietary changes for pregnant women. {M}ethods {T}he nutrient adequacy of the diet was evaluated using the {PAND}iet score, by comparing the nutrient intakes of 344 non-pregnant premenopausal women (18-44y) with dietary reference intakes for the first trimester of pregnancy. {S}imulations were performed to evaluate the theoretical efficiency of three types of ten successive tailored dietary changes in improving nutrient adequacy, with graded difficulty in implementation. {T}he acceptability (declared intention to use in the diet) of most efficient dietary changes was evaluated during an online randomized study including 115 {F}rench pregnant women (22-41y). {R}esults {M}odifying the amount consumed of foods (type-1) did not modify the food repertoire and resulted in the smallest theoretical efficiency (increase in the {PAND}iet score of 9.8 +/- 0.2 points), but changes were the most acceptable (probability of the intention to use: 0.30-0.78). {C}onversely, replacing food items by items from the same group or eaten at the same time (type-3) broadened the food repertoire (3.6 +/- 1.3 food subgroups added) and resulted in the greatest theoretical efficiency (+23.9 +/- 0.3) but changes were the least acceptable (0.07-0-23). {R}eplacing food items within the same subgroup (type-2) slightly broadened the food repertoire (+8.0 +/- 1.3 foods) and resulted in moderate theoretical efficiency (+14.8 +/- 0.2) and intermediate acceptability (0.11-0.35). {C}onclusion {A} clear trade-off exists between the theoretical efficiency and acceptability of dietary changes, with a graded broadening of the food repertoire.},
