Genes are not destiny! Environmental influences, including nutrition, stress and emotions, can modify those genes, without changing their basic blueprint. And those modifications, epigeneticists have discovered, can be passed on to future generations, as surely as DNA blueprints are passed on via the Double Helix.
Bruce H. Lipton, The Biology of Belief

Dr. Harold D. Foster spent 25 years developing a geographical approach to identifying the causes of diseases. This has shown that environmental variables, frequently minerals, play key roles in the development and diffusion of illness. Biochemical analysis of such spatially significant variables can then be explored to develop novel potential solutions.
This approach is based on tailored "orthomolecular compounds," which treat diseases or abnormalities resulting from chemical imbalances or deficiencies by restoring optimum levels of substances in the body, such as vitamins and minerals. This rebalances the body's natural, optimal functioning state and can prevent the onset of a disease or effectively reverse its symptoms.
This approach effectively repairs the damage caused by the disease and also corrects the underlying biochemistry of the body, which has permitted the disease to develop.
