Title: A Two-centre, Randomised, Single-blind, Parallel Group Controlled Trial, Testing the Growth Promoting Effect of Long-term Complementary Feeding of Infants With Different Doses and Formulations of Lipid-based Nutrient Supplements (LNS)
Brief Summary: The use of lipid-based nutrients (LNS), such as Nutributter or fortified spread (FS), have been associated with improved growth and development outcomes among infants in Ghana and Malawi. Modified versions of such supplements have been developed to improve their nutrient density and quality and to lower their costs. Such modified products have proven acceptable to infants and their guardians in Malawi and Ghana. In the present trial, the investigator aim to identify the lowest growth-promoting daily dose of modified LNS. Additionally, the investigators will test a hypothesis that LNS that does not contain milk promotes growth as well as milk-containing LNS when given for 12 months at a 10-40 g daily dose to 6-18 month old infants in rural Malawi.
