Abstract

An appropriate lifestyle and diet of pregnant woman during prenatal development contribute to the proper development of a foetus. Since the third month of pregnancy, physical activity should follow the metabolic needs. In this paper, linear programming has been applied in meal planning according to the guidelines recommended for women aged 19 to 30, with emphasis on nutrient intake during all nine months of pregnancy. Data used as the nutritional composition are based on the seven-day supply, where each day consisted of 4 meals; breakfast, lunch, dinner and snack. Linear optimization was carried out using the LINDO program. The program included 28 variables and 20 constraints; energy, water, proteins, fats, carbohydrates, cholesterol, dietary fi bres, vitamins soluble in fats; A, D, water-soluble vitamins, B1, B2, niacin, B6, folic acid,
B12, C, and minerals; calcium, iron, magnesium, and sodium. The results show that well-balanced, diverse and regular diet can be offered for pregnant woman based on prescribed guidelines providing adequate amounts of nutrients without taking additional supplements. The sensitivity analysis indicated that the menu planning has some limitations regarding the chosen foods in a weekly menu. Especially in the 3rd trimester it is important to include foods rich with folic acid, magnesium and iron.
