The study investigated households’ food nutrition perception at Mazimbu village in Morogoro municipality and the role of food nutrition perception on a household food diversity score. A household food diversity score could be an indicator of many nutrition aspects notably food accessibility and availability. Most previous studies assessing household food diversity especially in Tanzania have not considered the fact that a household may have a poor food diversity score not because of inaccessibility or unavailability but because of wrong food nutrition perception. The study involved 385 households targeting a married or single woman in a household. Households were selected randomly from a list of households provided by the village chairman of Mazimbu Village. Data from the households were collected using questionnaires which contained questions on households’ demographic characteristics, food nutrition perception and food diversity score.
