Fast food can be prepared and served quickly and includes items like burgers, pizza, fries, and donuts. While fast food is convenient and affordable, it often has little nutritional value and is high in fat, sugar, salt, and calories. The meat used in fast food comes from animals fed an unnatural diet and the high levels of unhealthy ingredients in fast food can increase risks of diseases like obesity, diabetes, cancer, heart disease, and hypertension. While fast food tastes good, it lacks fiber and healthy fats that the body needs, so consumption should be limited to maintain a balanced diet and health.
