Intervention. The intervention was a daily snack resembling local street
foods such as samosas and fritters, prepared fresh each day and fried in
sunflower oil. Treatment snacks contained leafy green vegetables in fresh
(;30 g) or dried (;7.5 g) form, full-fat milk powder (12–16 g), and dried
fruits (4–60 g) (Supplemental Tables 1 and 2). Control snacks were made
from low-micronutrient vegetables such as potato and onion. To avoid
monotony, we created multiple recipes from these foods (Supplemental
Table 3). On average, treatment snacks contained 10–23% of the WHO/
FAO recommended Reference Nutrient Intake for b-carotene, riboflavin,
folate, vitamin B-12, calcium, and iron; they contained 0.69 MJ energy
and 6.4 g protein, compared with 0.37 MJ and 2.4 g in control snacks
(Supplemental Table 2) (19, 20).
