Alkaline water – water with a higher-than-neutral pH level – is getting a lot of attention these days. Alkaline water can be supplemented with minerals and treated to “ionize” it, or make it more basic, as opposed to neutral or acidic. Proponents of alkaline water tout its health benefits as an antioxidant and detoxifier that helps to regulate the body’s pH levels, boosting energy and metabolism, speeding healing, slowing aging and guarding against chronic disease. However, there’s limited scientific evidence that shows alkaline water delivers these benefits. In fact, the body naturally works to maintain a neutral pH level of 7.0, as the ph levels of blood and most body fluids are around 7.0.
Scientists are still working to understand how much the pH of foods in our diet influences health. Overall, you can help your body function optimally by avoiding processed foods and sticking to a diet of vegetables, fruits, whole grains and high-quality proteins. Drinking plenty of water is also very important, but it doesn't need to be alkaline.
