The best medicine is ready for prime time

The cover issue of the Journal Science (arguably one of the best scientific journals) was on “Disease Prevention.” It features vegetables and fruits.
 
In my opinion, when the journal Science speaks, it is time to listen.
 
Hard to believe, but I have had intelligent, successful doctors tell me that there is no evidence that nutrition plays a role in health. Perhaps a few years ago that mind-boggling statement could have been argued, just because the data, and history thereof, have been dismissed, and at times suppressed, by those who stand to gain the most from keeping people ignorant about food being the best medicine. Today, the weight of evidence is so overwhelming that any opposition reveals profound ignorance, and perhaps protection of gains and turf.
 
Let me borrow from Dr. Jeffrey Bland’s excellent FMU notes:
 
“Industrialized food has not helped: Cultural and other biases have distorted the historical record, leading to conclusions which test many current health policy assumptions about a steady improvement in British nutrition since the nineteenth century.
 
As these papers show, the urban mid-Victorians, including the working classes, ate a notably good diet, including significant amounts of vegetables and fruit, which enabled a life expectancy matching that of today. We follow the example of George Rosen (a public health practitioner, and in his time editor of the American Journal of Public Health and Journal of the History of Medicine, among others), in believing that a historical dimension is essential to a sound perspective in public health today.” He continues in part three of the series: “Where our previous two papers documented the volume and variety of the mid-Victorian diet, this final paper reveals that the mid-Victorian diet conferred extremely significant protection against the major degenerative diseases, even amongst those who, because of their extremely limited incomes, might be considered to be significantly undernourished and so vulnerable to such afflictions.”
 
“The Incidence of cardiovascular disease and cancer were relatively rare observations. Rather the trend in Victorian England was to carry on almost fully functional until the end of life, with the majority of people succumbing to overwhelming infection or—in many cases—fire. Dr. Clayton attributes the reduced incidence of degenerative disease in Victorian England to a combination of several factors:
 
1. Consumption of traditional foods, including heirloom varieties of fruits and vegetables with many bitter and aromatic notes. Also, they were not consuming any processed foods apart from the very basics: bread, butter, cheese. Fish was a common source of protein. All together, the intake of phytonutrients (flavonoids, phenolic compounds, carotenoids,xanothophylls, methyl group donors, cyanogens, etc.) is estimated to be two to three times higher than today.
 
2. With a very small upper and middle class, most everybody else in that era is blue collar, and working manually with their hands. No portable fuels were available other that coal and wood, and the internal combustion engine was yet to be invented. With no laborsaving technology available, there was a huge difference in the level of physical activity then. Dr. Clayton suggests individuals were better muscled than they are today, and as a result their muscles were far more effective, resulting in the slim to thin Victorian phenotype commonly seen in photographs of the era.
 
3. Incidence of cancer in the Victorian era was lower than today and peak age of onset for those who did present with cancer was noted to be in early middle age. Dr. Clayton suggests this demonstrated that cancer was not age-related in such a nutritionally protected population, but rather became manifest only in individuals who were truly genetically vulnerable.

    Hi. I'm Manoa Torres, I'm 28 and I live in Chile.

    In my country does not exist an institution where I could study Netural Medicine or Naturopathy, so I would like to know if I could study with ypu from here. What do I need to do to make this possible?

    Regards!!
