What Makes a Food a Superfood?
While the term "superfood" is often used for marketing, it’s generally understood to refer to foods with a very high nutritional density.

Including a variety of these foods in your diet can support your health in numerous ways, from reducing inflammation to boosting immunity. The key is to think of them as power-packed components of a balanced diet, not magic cures.

Relying too heavily on a single food can be detrimental, and a balanced, diverse diet is what truly promotes long-term health. Remember that all fruits, vegetables, whole grains, and legumes offer valuable nutrients. Filling your plate with a rainbow of unprocessed foods is the most effective strategy for a healthy diet, with superfoods simply being an extra powerful component.
