Which is one of the few drinks to be considered a superfood?

Water is essential for life and supports all bodily functions - hydration, temperature regulation, nutrient transport, waste removal - making it fundamental to health. While wine and cranberry juice have some beneficial compounds, they also have downsides (alcohol, sugar). Coffee has antioxidants but isn't classified as a superfood in nutritional frameworks. Water's complete absence of calories, additives, and its universal health necessity makes it the clear answer.
