New, Large-Scale Study Links Dairy to Parkinson’s Disease

Numerous studies* going back several years have found an association between dairy consumption and a higher incidence of Parkinson’s disease. Now “Intake of dairy foods and risk of Parkinson disease”, a new study published this week in Neurology, the Official Journal of the American Academy of Neurology, has gone further, concluding that there is, in fact, a greater risk of developing Parkinson’s in individuals who consume three or more servings of some dairy products per day over those individuals who consume less than a single serving per day.

The large-scale study, conducted through the Harvard University T.H. Chan School of Public Health in conjunction with the National Institutes of Health and published June 7, 2017 found specifically

  1. Consuming at least three servings of low-fat dairy a day is associated with a greater risk of developing Parkinson’s disease compared to consuming less than one serving a day, and
  2. Drinking more than one serving of low-fat or skim milk per day is associated with a greater risk of developing Parkinson’s disease compared to drinking less than one serving per week

The study, as described by researcher Katherine C. Hughes, ScD, of the Harvard Chan School of

Carnivores or Herbivores – Do Humans Need Meat?

Any vegan or vegetarian, or meat-eater seeking information can find what seems to be scientific-based and scholarly authority for either side of the argument as to whether humans are or are not natural carnivores and thus require the consumption of meat in order to attain and maintain good health. While the traditional view, espoused by generations of meat-consuming scientists, anthropologists and meat-industry purveyors, is that meat provides essentials to human health and that this is supported by the inescapable existence of numerous anatomical traits, this belief is susceptible to many valid arguments that mitigate against its validity.

Those espousing the natural carnivore argument cite both anatomical arguments and those based on evolution, as well as the chemical needs of the human body. The best evidence for a meat-based diet, they argue, includes such allegations as the presence of human teeth that include incisors and canines designed for biting and tearing and ripping flesh, and molars designed for chewing. They even argue that animals with this type of diversity in their mouths are “built” to be omnivores. They also allege that our closest relatives, along side whom we developed from common ancestors, are the chimpanzees. Chimpanzees are, of course, carnivores,

and thus, the argument goes, so must be humans. Physiologically speaking however, chimps are stronger and faster, have larger incisors, and overall are significantly better predators than are humans, but the analogy is still commonly made. And don’t forget that while your average chimp loves a good steak, their primary diet is, in truth, composed more of vegetables, Continue reading
