is it possible to find out about diseases earlier?

The answer is yes! That's why blood evaluation techniques were developed - to uncover the potential for disease that, if left untreated, can lead to illness and degenerative disease.

If pre-symptomatic indicators of degenerative disease, caused by dietary, environmental or lifestyle factors, are present in the blood, then the blood scan will find them. Blood evaluation doesn't actually diagnose such diseases, but it rather highlights the potential for disease to develop, and suggests guidelines to encourage improved performance and a return to high levels of wellness.

Professor Denham Harman ("father of the free radical theory of aging") said aging is now understood to be a culmination of oxidative damage which causes the cell to fail. Managing the aging process is a matter of reducing the oxidative damage through lifestyle and diet.
