The Truth Behind the 99% Water Myth
The idea that a fruit is composed of 99% water is a common misconception, often found in popular puzzles and internet discussions rather than actual nutritional data. The reality is that while some fruits come remarkably close to this figure, none reach the 99% mark. The highest water content belongs to the cucumber, which, though often used culinarily as a vegetable, is botanically classified as a fruit because it develops from a flower's ovary and contains seeds. With a water content reaching up to 97%, the cucumber is an outstanding choice for natural hydration. This dispels the notion of a 99% water fruit while highlighting genuinely hydrating and nutrient-rich options.
