Despite a reduction in malnutrition in Peru over the past few decades, malnutrition remains prevalent in some areas of the country. Increasing infants’ and toddlers’ consumption of animal-source foods improves their growth and development, and is seen as a significant method of combating malnutrition. The Institute of Nutritional Research (IIN) based in Lima, Peru explored a method of reducing child malnutrition by addressing the consumption of animal-source foods in two districts in Northern Peru, Morrope and Incahuasi. Anthropologists conducted formative research in these areas to explore some of the underlying causes of malnutrition. Through this research, the IIN learned that some of the potential contributing factors to malnutrition are ethnotheories that the consistencies of animalsource foods are not appropriate for young children for fear of that they would cause choking or stomach problems (Bartolini et al 11). Researchers then carried out a pilot study to assess whether a manual food grinder that changes the consistency of animal-source foods has the potential to facilitate caregivers’ providing of more animal-source foods to their children ages 6 to 18 months. An overview of child malnutrition globally and in the region of Incahuasi, a discussion of the importance of animal-source foods in reducing malnutrition, and a summary of the methodology and preliminary results of the grinder household trials conducted in Incahuasi are discussed below.
