I congratulate these researchers for looking into realistic options 
involving real food!  We need more of this type of research if we want data to help promote dietary diversification.  It is at least a start.

ABSTRACT
In most developing countries, complementary foods are based on staple cereal 
or root crops. Imported or commercially developed foods generally are not 
used by low-income rural households due to high cost and poor availability.

To improve the quality of children's diets in Southern Ethiopia, two 
complementary foods were formulated based on corn, or on an indigenous root 
crop (Enset ventricosum)product called kocho. Kidney beans and pumpkin pulp 
were used to improve the protein and vitamin A values, respectively. Kidney 
beans and corn were soaked,germinated and lightly roasted before grinding. 
Four formulations of complementary foods were prepared. Two of them were 
traditional corn- or kocho-based, and served as controls. The other two were 
supplemented formulations, and contained either corn:kidney bean:pumpkin 
(CBP) or kocho:kidney bean:pumpkin (KBP). Crude protein and fat, amino acid 
profile,
and carotene content of the corn, kocho, kidney bean, and pumpkin were
determined by standard AOAC methods. The four formulations were evaluated 
for sensory acceptability in Southern Ethiopia by mother and child pairs.

The CBP and KBP formulations had crude protein contents of 14.07 g/100 g and 
13.81 g/100 g, respectively, while the traditional corn and kocho had only 
8.82 g/100 g and 1.46 g/100 g, on a dry weight basis. Adding kidney beans to 
both mixtures improved their essential amino acid profiles, but the need to 
serve the foods as thin porridge for infants created low energy density 
products. The pumpkin in CBP and KBP provided 54 µg RAE per 100 kcal, 
increasing the Vitamin A value of the mixes by 25- and 180-fold, 
respectively. Sensory evaluation of CBP by 30 mother and child pairs, and 
KBP by 28 pairs indicated high acceptability (4.7 - 4.9
on a 5-pt Hedonic scales) of the complementary foods. Acceptability scores 
of CBP and KBP were not significantly different (p > 0.05) from those of the 
traditional corn and kocho formulations. Thus, addition of kidney beans and 
pumpkin is a potential way to increase the nutritive value of traditional 
Ethiopian complementary foods prepared from corn or kocho.
