Unhealthy food, often referred to as junk food, typically contains high levels of sugar, salt, and unhealthy fats. These foods are often low in essential nutrients and can lead to various health issues, such as obesity, diabetes, and heart disease. Common examples include fast food, sugary snacks, and processed meals. Many people enjoy junk food for its convenience and taste, but regular consumption can negatively impact overall health. It is important to balance these foods with healthier options, such as fruits, vegetables, and whole grains, to maintain a nutritious diet and support long-term well-being.
