These foods are low in unhealthy fats, added sugars, and sodium while being rich in fiber, antioxidants, and essential nutrients.
Below, we’ve curated a list of the top 25 healthiest foods, ranked based on their nutrient density, versatility, and contributions to a balanced diet. Each food is backed by USDA data and includes practical tips for adding it to your meals.
