Why? First, the water content in an apple is just under 90%. Just like so many fruits and vegetables.
Secondly, the fiber in the apple helps retain hydration in your body.
Finally, and perhaps the most important, the water inside the apple is a different kind of water, structured and energized by photosynthesis.
And the different kind of water in the apple will make the water in the bottle of water work better too. An apple is Nature’s answer to plastic water bottles. Best packaging on the planet!
