In each of our bodies, we have cell damaging activity happening on a daily basis. This is something that neither you nor I can stop from occurring in the body. But it is something we can battle with hydrogen.
A by-product of the ATP production process or fuel generation process in the cell is the creation of oxidative stress. This is a prat of life and can't be helped. When this process goes unchecked, then the body is unable to balance the damage being done on a cellular basis.
It's kind of like if the police decided to go on vacation and never come back, chaos and crime would terrorize the city.... Sadly this happens too often in our bodies where the oxidative stress is left unchecked and able to run rampant in our bodies.
Due to our physiological design, our bodies should be able to fight this naturally. However, We have disrupted and damaged this process to the point of no return in many individuals. With the pollutants in our environments, misunderstood dieting, poor water quality, and excess stress in our lives, cancer and disease is increasingly on the rise.
It's an epidemic.
