Read the detailed description

Study design: A two-year longitudinal effectiveness study Sample selection: Hundred families will be selected for this study, 50 in each group.

For the test group, people/families buying the standardized milk habitually will be identified and offered the study, an ethics approval would be obtained before commencing the study. After a consent is signed, a home visit will be made and family will be given information about the study.

Individuals from families who consume standardized fortified milk + fortified oil will be offered the study. The control group will consist of families consuming unfortified milk and oil. Thus, families habitually consuming unfortified milk and oil (from 'ghanas') will be offered the study.
