Watermelon seeds are small, oval-shaped seeds found in the center of watermelon fruits. While they are often discarded, they are edible and can be roasted and eaten as a snack, similar to pumpkin seeds. Watermelon seeds are a good source of protein, healthy fats, vitamins, and minerals like magnesium, iron, and zinc. They have a mild, nutty flavor and can add a crunchy texture to dishes or be enjoyed on their own. However, they should be eaten in moderation as they can be high in calories.
