The nutrient content presented in this table reflects the increase of 25 % of the initial recipe that occurred after 3 months of the study because of a prolonged drought and food shortage in the study area.
Availability of the snack's Fe and Zn is assumed to be equal to the average availability across the day's intake (9 % and 13 % for Fe and Zn, respectively). If the snack is consumed alone, availability would be higher for the meat snack; available Fe would be ~0·53 mg and available Zn ~1·36 mg.The snack was consumed alone almost all of the time.
This value reflects the amount of vitamin A originally calculated based on the known ingredients using the WorldFood 2 Dietary Assessment Program and analyses of known ingredients by Medallion Laboratories. This value does not include the retinol from the commercial oil added to make snacks isoenergetic. This oil was not labelled as retinol-fortified by the manufacturer (Unilever, East African Industries, Nairobi, Kenya) until some time after the study began.
