Abstract
The present investigation was carried out to formulate a Nutrient Dense Ingredient
Mix (NDIM) and to assess its efficacy in improving the energy and iron status of rural
Punjabi women. After various organoleptic trials the most acceptable combination of NDIM
with semolina (45g) , pearl millet (5g), whole green gram (10g), dried fenugreek leaves (10g),
peanuts (10g), fat (15g) and other functional ingredients (5g) was selected, which was further
subjected to nutritional evaluation. It was revealed that 100g of the cooked NDIM provided
437.4 Kcal of energy, 13.58g protein, 3.62mg iron, 42.39mg calcium, 0.92mg zinc and also
had 69, 72 per cent of in vitro carbohydrate, protein digestibility respectively. To assess the
shelf-life of the formulated mix, various parameters including free fatty acids (% oleic acid),
peroxide value (mcq/kg), total viable count (cfu/g) and organoleptic acceptability were also
determined. All these parameters showed a non-significant (p>0.05) change after 3 months of
storage in air tight glass jars at ambient temperature. Furthermore, the efficacy of developed
mix was tested on adult (18-50 years), undernourished (BMI<18.5 kg/m2) and anemic (Hb<12
g/dl) women. Sixty women from nearby villages of Ludhiana district were selected and
equally divided into control and experimental groups. The experimental group was
supplemented with 100 g of NDIM (the dose was decided based on the gap between energy,
protein and iron intake and RDA of the Indian women received for the last 20 years) daily for
120 days along with nutrition education on a fortnightly basis whereas the subjects from the
control group received no supplementation or nutrition education. Post intervention the
adequacy of nutrients namely energy, protein and iron increased by16.9, 23.9, 16.8 per cent
respectively among the experimental group subjects, resulting in a significant (p<0.05)
increase in the nutritional indices of the selected subjects. The weight, BMI and hemoglobin
of these subjects increased by 2.28 kg, 0.91kg/m2 and 0.68g/dl respectively. The pre and post
assessment of the Knowledge, Attitude and Practice (KAP) score of the control and
experimental group depicted a significant (p<0.05) improvement in the scores of the
experimental group. Thus, it can be concluded that the nutrition intervention in terms of
supplementation along with nutrition education can be an effective tool in improving the
nutritional status of undernourished women.
