In particular, for low-income people it is of interest which alternative diet form rich in Ca leads to the lowest additional costs. This study aims to calculate the additional costs of lactose-reduced diets and to show which of different options represent the most cost-effective alternative within a lactose-reduced diet.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980021002779_as2\"><jats:title>Design:<\/jats:title><jats:p>Using linear programming, food baskets with different lactose contents were calculated and were compared to a basic model, reflecting a normal diet without a limitation of lactose. By comparing the costs and the composition of the food baskets, recommendations for a lactose-reduced diet were derived.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980021002779_as3\"><jats:title>Setting:<\/jats:title><jats:p>Germany.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980021002779_as4\"><jats:title>Participants:<\/jats:title><jats:p>A consumer panel dataset representative for Germany is used for the calculations.

It was found that the greatest adjustments due to lactose reduction could be observed within the dairy product group. In this group, with a rising lactose limit, normal milk was increasingly replaced by lactose-free milk.<\/jats:p><\/jats:sec><jats:sec id=\"S1368980021002779_as6\"><jats:title>Conclusion:<\/jats:title><jats:p>It was shown that a lactose-reduced diet is generally associated with higher food costs.
