Number one answer.....Hydration! No other liquid is as good for the body as water. Lemon water aids in digestion and freshens breath.
The vitamin C protects the body from free radicals, and is believed to lower the risk of stroke and high blood pressure. One study even states that vitamin C helps reduce wrinkles.
Plus lemons have been found to reduce weight gain and reduce insulin resistance in mice.
So it's a win win!
