Interpretive Summary: Madagascar, with over 25 million people living in an area the size of France, is at a nutritional crossroads. Micronutrient-poor staples, especially rice, roots, and tubers, comprise nearly 80% of the Malagasy diet by weight. Here, we used dietary records sampled daily over the course of nearly one year to comprehensively characterize the consumption patterns of Malagasy people living in two localities of northeastern Madagascar. We compared the results of these daily dietary records to three commonly used food security and nutritional measurement indicators, the Household Dietary Diversity Score (HDDS), the Food Consumption Score (FCS), and the 24-hour recall. HDDS and FCS confirm the high diversity of the diet, but generally fail to predict nutrient intake accurately. 24-hour recalls can predict true nutrient intake but only after exhaustive survey effort. Despite the diverse diet, when comparing household intake of a wide range of nutrients relative to estimated average requirements, adjusted for the demographic structure of each family, we found pronounced deficiencies. Malnutrition in Madagascar is multi-dimensional, indicating the need for more detailed biomedical and socio-economic research on the patterns and determinants of nutrient deficiency and sufficiency.
