Passage: Read the given passage and answer the questions that follow. Food is essential for life, providing the necessary nutrients that fuel our bodies and support growth, repair and overall health. Proper nutrition is crucial for preventing illness, maintaining a healthy weight, and enhancing cognitive function. There are two main types of food: healthy food and junk food. Healthy foods are nutrient-rich, naturally sourced and unprocessed, providing essential vitamins, minerals, fibre, proteins and healthy fats for overall well-being. Healthy foods enhance immunity, support organ health and supply lasting energy through fibre and protein. In contrast, junk foods are nutrient-poor and highly processed, and contain artificial additives and preservatives, leading to quick energy spikes followed by fatigue and overeating. Diets rich in healthy foods benefit mental health, mood and cognitive function, while regular junk food consumption has been linked to increased anxiety, depression and poorer mental well- being. Choosing healthy foods promotes sustained energy and a balanced mind and body. It is better to eat healthy food instead of junk food because nutritious foods are essential for overall well-being, while junk food offers little nutritional value and can lead to long-term health issues like obesity and heart disease. Question: What is the main idea of the given passage?
