It never ceases to amaze me how stridently opposing views are voiced from health and medical professionals inhabiting the same world of healthcare, and who all supposedly must be reading the same research. It simply does not, and never has computed for me how eminently qualified physicians and research scientists can repeatedly state throughout the various media – print, broadcast and social networking – that, for example, there is no science or medical evidence about vitamin C, or that nutritional therapy can be called pseudo-science.

My partner Mike Howell and I launched Positive Health PH Online in 1994, following my setting up of the Cancer and Nutrition database for the then Bristol Cancer Help Centre (BCNH) [now Penny Brohn Cancer Care]. One of the main objectives for Positive Health was to make available to health professionals and individuals seriously interested in non-drug treatments, authoritative information published in the scientific literature across the spectrum of natural / complementary / alternative health approaches.
