Healthy eating doesn’t have to be complicated or expensive. In fact, some of the most powerful foods for your body are the simplest ones you can buy. Fresh vegetables like spinach, broccoli, and carrots supply essential vitamins that keep your immune system strong. Whole grains such as oats and brown rice help maintain steady energy throughout the day. Lean proteins — chicken, fish, beans — support muscle health and keep you full longer. Nuts, seeds, and avocados deliver healthy fats that benefit your heart and brain. Adding these foods to your daily routine can make a noticeable difference in how you feel, without drastic diets or strict rules.
