Abstract. Khariri, Andriani L. 2020. The predominance of non-communicable diseases and unhealthy eating patterns. Pros Sem Nas Masy Biodiv Indon 6: 624-627. Indonesia in the last decade has a double burden, namely infectious and non-communicable diseases. This is related to the slow decline in the incidence of infectious diseases and even tends to persist, but on the other hand the incidence of non-communicable diseases is moving fast enough and more dominating its impact. The World Health Organization (WHO) reports that nearly two-thirds of deaths worldwide are caused by non-communicable diseases. The mortality rate due to non-communicable diseases is expected to continue to increase worldwide with the largest increases occurring in low and middle-income countries. The main risk factors for non-communicable diseases include unhealthy community dietary behavior. This paper examines several types of non-communicable diseases that are affected due to unbalanced and unhealthy consumption behavior as a risk factor. In the results of the Basic Health Research (Riskesdas), several non-communicable diseases found a high prevalence such as stroke, hypertension, diabetes mellitus, heart disease, cancer and chronic kidney failure. In the list of diseases that are the highest causes of death in Indonesia, non-communicable diseases dominate the treats, whereas infectious diseases are only tuberculosis, which still plays the second highest cause of death after stroke. The burden faced by the Indonesian people in tackling health problems is increasing with the existence of an epidemiological transition marked by a shift in causes of death for all ages from infectious diseases to non-communicable diseases.
