Why is Don trying to correlate this study with PH?
It all sounds a bit vague and correlation does not prove causation. As was brought up by a number of members, there are many other factors that need to be taken into account.
The Alaskan Eskimo population has the highest incidence of degenerative joint disease, while the Pecos Indian population experienced the least. This was explained by the possibility of less continuous stress among the latter (Jurmain 1991).
Here's the study:
Comparative osteological analysis of the knee, hip, shoulder, and elbow joints of 789 individuals from four human skeletal populations (Black and White Americans, Pueblo Indians, and Alaskan Eskimos) indicates that age of onset, frequency, and location of degenerative changes are directly related to the nature and degree of environmentally associated stress, as reflected by the variable life styles of the populations sampled
Functional stress, when constant and severe in nature, becomes the primary focus of degenerative disease, but other background contributing agents such as age, sex, and hormonal influence must not be ignored
There's certainly nothing in there that shown a high meat consumption causes osteoporosis.
It's just as much a stretch of the facts as his tubers argument.
The "Seven Deadly Sins"
• Grains (wheat/rice/oats etc) . . . . . • Dairy (milk/yogurt/butter/cheese etc) . . . . .• Nightshades (peppers/tomato/eggplant etc)
• Tubers (potato/arrowroot etc) . . . • Modernly palatable (cashews/olives etc) . . . • Refined foods (salt/sugars etc )
• Legumes (soy/beans/peas etc)
