Effect of Micronutrient-Fortified Malt on Body Iron Stores and Growth in Infants with Cleft Lip and Palate: A Randomized Controlled Trial
This randomized controlled trial demonstrates that providing micronutrient-fortified malt to infants with cleft lip and palate significantly improves their iron status and short-term weight gain, although it does not fully reverse chronic long-term growth deficits.

For many infants, the first year of life is a time of rapid transformation, where the body grows and the brain develops at a pace that demands a constant, rich supply of fuel. When a baby is born with a cleft lip or palate, a gap in the roof of the mouth or the lip itself, this natural process faces a significant hurdle. The physical structure makes it difficult to create the suction needed for breastfeeding or bottle-feeding, often leading to missed meals, slower weight gain, and a higher risk of infection. Because of these feeding challenges, these children are particularly vulnerable to a hidden form of hunger: a lack of essential vitamins and minerals in their diet. One of the most critical missing pieces is iron, a mineral that acts as the body's oxygen carrier. Without enough iron, a child can become anemic, leaving them too weak to undergo the corrective surgery needed to fix their cleft. The question facing doctors and nutritionists has long been whether a specific type of dietary support could bridge this gap, helping these infants build up their strength and iron reserves just in time for their operations.
A team of researchers in India set out to test a practical solution for this problem. They focused on a group of infants between five and seven months old who had been diagnosed with cleft lip and palate. These children were preparing for their first major surgery to repair the lip, but they needed to reach a certain level of health before they could proceed. The researchers recruited nearly one hundred mother-infant pairs and divided them into two groups. One group received the standard care they would normally get, which included advice on how to feed their babies and a basic, unfortified malt powder to mix with their food. The other group received a similar amount of malt powder, but this version had been specially enriched with iron, zinc, and vitamin C. The goal was to see if this extra boost of nutrients, given daily over a six-month period, could improve the babies' blood health and growth before they returned for their second surgery to repair the palate.
The results of this six-month journey revealed a clear difference in the blood health of the two groups. By the time the infants were ready for their palate surgery, the children who had received the fortified malt showed a marked improvement in their iron status. Their blood contained significantly higher levels of hemoglobin, the protein that carries oxygen, and their bodies held more iron in storage compared to the group that received the standard malt. The researchers measured these changes by drawing blood at the start of the study and again at the end, finding that the fortified group had successfully built up their iron stores. In contrast, the group receiving the standard diet saw their iron levels drop slightly over the same period. While the fortified group did not completely eliminate the risk of anemia, the rate of iron deficiency was lower in that group, suggesting that the nutrient boost was working to protect the children's health.
Beyond the blood tests, the study also looked at how the children were growing. The researchers measured the infants' weight, length, and head circumference to track their physical development. The results here were more mixed. The children in the fortified group did gain a bit more weight relative to their age compared to the control group, indicating a short-term improvement in their nutritional status. However, the study found that the long-term growth deficits, such as being shorter than expected for their age, persisted in both groups. This suggests that while the fortified food helped the children recover from immediate nutritional gaps and build up their iron, it could not fully reverse the deeper, long-term growth delays that often accompany cleft conditions. The researchers noted that factors like recurrent infections and the inherent challenges of the deformity itself likely play a larger role in long-term height than diet alone.
The study also examined whether this nutritional support helped the children get to the operating room on schedule. The hope was that better-nourished infants would be ready for surgery sooner, avoiding delays that can happen when a child is too weak or anemic to undergo the procedure. While the fortified group did show better health markers, the timing of their surgery did not differ significantly from the control group. Both groups had a similar number of children who underwent the palate repair on time and those whose surgeries were delayed. This indicates that while the fortified malt successfully improved the children's iron levels and short-term weight, the decision to delay surgery is influenced by many factors beyond just iron status, such as other illnesses or logistical issues.
Ultimately, the research demonstrates that adding a specific blend of micronutrients to the diet of infants with cleft lip and palate can effectively improve their iron stores and prepare them better for surgery. The fortified malt acted as a targeted supplement, filling the nutritional void that often exists in the diets of these vulnerable children. It did not, however, solve every aspect of their growth challenges, highlighting that while nutrition is a powerful tool, it works best as part of a broader care plan. The findings suggest that integrating such nutrient-dense, locally acceptable foods into routine care could be a vital step in ensuring these infants are strong and healthy enough to undergo the life-changing repairs they need.
