Dr. Preuss is a strong believer and advocate of so-called "syndrome X", which claims that the chronic disorders that are common in the aging population, such as hypertension, diabetes, obesity, and arteriosclerosis, are all associated, at least in part, with disturbances in glucose/insulin metabolism. He believes that the findings in his initial study indicate that maitake D-fraction would favorably influence the glucose/insulin system and help prevent the onset of age related chronic disorders.
