Human diet planning is generally carried out by selecting the food items or groups of food items to be used in the diet and then calculating the composition.
If nutrient quantities do not reach the desired nutritional requirements, foods are exchanged or quantities altered and the composition recalculated.
Iterations are repeated until a suitable diet is obtained.
This procedure is cumbersome and slow and often leads to compromises in composition of the final diets.
A computerized model, planning diets for humans at minimum cost while supplying all nutritional requirements, maintaining nutrient relationships and preserving eating practices is presented.
This is based on a mixed-integer linear-programming algorithm.
