Poor food choices are just one factor that causes our blood to lose an alkaline balance. Stress, anxiety, depression, sleep deprivation, and pollution can also contribute to a highly acidic pH level. A consistent alkaline-acid balanced diet will slowly correct these disturbances. I have seen many quickly improve their health situation with this awareness and a few simple changes. I follow this balance pretty closely because I believe it keeps me healthy and helps compensate for the stress in my life as well as the pollutants in my environment.
