Yes, watermelon seeds are safe to eat. Both black and white watermelon seeds can be consumed without harm. The black seeds are mature and fertile, while the white seeds are immature and softer. Eating watermelon seeds will not cause a watermelon to grow inside the stomach, which is a myth.
Watermelon seeds also provide nutritional benefits. They are a good source of protein, fiber, magnesium, iron, and other nutrients important for heart, muscle, and bone health. They contain healthy fats as well and can be eaten raw, roasted, or prepared in other ways to maximize nutrient absorption.
However, overconsumption of watermelon seeds may cause digestive discomfort such as constipation or bloating due to their high insoluble fiber content. Also, because they have fat, eating large amounts could be a concern for some people. Watermelon seeds can pose a choking hazard in children or individuals with swallowing difficulties, so caution is advised.
In summary, watermelon seeds are safe and nutritious when eaten in moderation. Roasting or cooking them can further enhance their digestibility and nutritional benefits.
