Maternal nutrition is very important for the wellbeing of pregnant women, childbirth, and lactating women, which are crucial and meant for the wellbeing of a mother and newborn baby. This narrative review discusses nutritional malpractices, motivational drivers, and their consequences typically from Ethiopian pregnant women’s context. Different studies (regarding less of study design and type) done among pregnant women (aged 15–49 years) by considering pregnancy-related outcomes and timing of nutritional malpractices were included mostly. Accordingly, taboos of healthy diets, craving for unhealthy foods (sweet, fat, raw, and salty/spicy foods), and nonfood items (soil, coffee residue, stone, and ash) were practiced majorly by the women. The birth difficulty, fetal head plastering, fetus discoloration, fetus burns, abortion, and abdominal cramp are the primary drivers of taboos of healthy diets. Hormonal change and social and nutrient-seeking behavior are the most prevalent drivers to the consumption of unhealthy foods. Additionally, personal interest, flavor, and color of items are important motivators to practice pica. Such pica practice hurts nutrient intake, absorption of iron/zinc, abdominal health, and diarrhea occurrence. Food taboos are high predictors of health disorders, such as intrauterine growth restriction, infection, bleeding, preeclampsia, stillbirth, early birth, low birth weight, retarded development of cognitive, and anemia. Craving and eating unhealthy foods were interconnected with chronic disease development (hypertension, diabetes, heart disease, and cancer), discomforts, preterm labor, preeclampsia, and intrauterine growth restriction in women. Additionally, it is also associated with stillbirth, low birth weight, obesity, birth defect/deficit, hypertension, cancer, diabetes, metabolic syndrome, renal disease, decreased fetal growth, behavioral change, heart failure, and poor cognitive development in the infant. Overall, these nutritional malpractices are significantly associated with many argumentative pregnancies as well as developmental consequences leading to the direction of infant and maternal mortality and morbidity. Therefore, urgent implementation of health and nutrition education programs considering food misconceptions and beliefs regarding pregnancy and use of ground-breaking ways to play down the negative and maximize potential positive dietary effects designed by the government of Ethiopia could also serve as a long-term solution to the problem.
