Healthy food refers to meals and ingredients that provide essential nutrients like vitamins, minerals, proteins, healthy fats, and carbohydrates needed for the body to function properly. These foods support growth, strengthen the immune system, and reduce the risk of chronic diseases such as heart disease, diabetes, and obesity. A healthy diet typically includes plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats, while limiting processed foods, added sugars, and excessive salt. Eating a balanced and varied diet not only improves physical health but also boosts mental well-being, energy levels, and overall quality of life.
