Certain cruciferous plants, such as mustard, horseradish, watercress, and radishes, being digested in the stomach of people and some herbivores in the presence of pepsin, hydrochloric acid and a particular frequency of electromagnetic sine wave from high tension electric lines have a specific protein altered to a different shape. 

These altered proteins may be inside people or may be ingested in meat from contaminated herbivores. They are not digestible. They invade cells and take over the protein manufacturing machinery of the cell to reproduce themselves. They weaken the function of the cell but do not kill it.

Infected cells divide at 111% of the normal rate. Infected tissues become less effective as the percentage of cells with altered proteins increases.
