Prof. Dr. Yukie Niwa graduated from the Faculty of Medicine of the top Japanese University, Kyoto University in 1962. He holds a Ph.D in medicine and is the Director of the Niwa Institute of Immunology. He is also the director of Tosashimizu Hospital and Chairman of JAPAN SOD Education Association.

Dr. Niwa has been involved in clinical research into oxygen radicals and SOD for many years both in Japan and internationally. He is now recognized as a world authority in this field. Dr.Niwa uses plants and grains from nature to develop his own low-motecular antioxidants, including SOD-action like foods and organic anti-cancer medicines and has been extremely successful in the treatment of various diseases including cancer with these products at his hospital. He had written a number of books in Japanese and two in English ("Free Radicals invite Death" & "Drugs Do Not Cure Disease"), are now available here

Oxygen radicals are produced in our body system to fight against viruses and bacteria which happened to enter into our body. Due to a number of factors such as environmental pollution, chemicals, stress under modern-day lifestyle etc, more oxygen radicals may be produced than necessary. These excess oxygen radicals(also called free radicals), if not neutralized, could cause a number of problems including attacking the body's own cells, resulting in the cells attacked to become cancerous or combine with lipids (fats and oil) forming lipid peroxices which cause blockages and thinning of the inner walls of the blood vesseis.

in fact, 90% of modern day illnesses are caused directly or indirectly by excess oxygen radicals and lipid peroxides. These illnesses range from minor problems like prema-ture ageing, wrinkles, age spots, pigmentation of skin and more serious illnesses such as high blood pressure, cataracts, to dreadful illnesses including diabetes, heart attacks, strokes and cancer. Most scientific researches concluded that for human body body, ageing process is the ultimate cumulative effects of long-term destruction of body cells by excess oxygen radicals.

An enzyme, Super Oxide Dismutase(SOD), is produced by cells in the body to neutralize these excess oxygen radicals. This is the workings of our body's immune system. Ideally, the SOD produced in our bodies should neutralize all the excess oxygen radicals. That would be perfect but is not always the case and especially so if one is not in good health or as one ages and more so for those whose age is 40 years old and above. This explains why as one gets older, the likelihood of illness increases, due to the lower SOD induction capacity (the ability of the body to increase SOD as free radicals increase) of the human body. That is SOD induced human body.
