New study: "Association Between Myocardial Infarction and Fractures: An Emerging Phenomenon."
Most interesting is this, quote:
...substantial temporal variations were noted (
1979 to 1989: hazard ratio, 0.81 ...
1990 to 1999: hazard ratio, 1.47 ...
2000 to 2006: hazard ratio, 1.73 ...
Trends were similar regardless of age, sex or fracture site. Conversely, the overall hazard ratio for death in MI cases versus controls did not change materially...
The only obvious factor that was different in the first decade (blue - less osteoporosis following a MI event) as opposed to the second and third decade of the study (red - more osteoporosis!) is the common usage of statin drugs! Perhaps a popularity of the low fat high carbohydrate diets in treating MI patients (the so-called AHA diet) may be another factor distinguishing the red from the blue decades.
Another recent study found on Dr.McDougall forum, linking bone underdevelopment with malnutrition, in this case a lack of dairy products:
Thin Bones Seen In Boys with Autism and Autism Spectrum Disorder
The boys in the study who were on a casein-free [READ DAIRY-FREE (added by H.)] diet had the thinnest bones. In fact, the 9 boys who were on a casein-free diet had bones that were 20 percent thinner than normal for children their age. Boys who were not on a casein-free diet showed a 10 percent decrease in bone thickness when compared to boys with normal bone development.
The study authors wrote that bone development of children on casein-free diets should be monitored very carefully. They noted that studies of casein-free diets had not proven the diets to be effective in treating the symptoms of autism or ASD.
As a side note from my own experience. It reminds me that a nurse examining children at my school in the Eastern Europe, 1960-ties (I was around 12) told us that many, about a half had unusually thin but long bones in their hands and different elbow joints, as compared with the medical reference books that she used. Those children had normal food intake, were rather well fed. I always wondered what was causing the difference and that the same factor affecting bone development may have also affected the risk of autism! What was that factor? We didn't eat breakfast cereals nor drank pop. We ate a high carb medium fat diet not much different from that of the 1930-ties or before. Definitely more sugar - sugar became very cheap in the 1960-ties, and margarine became the new "health" "food" of the day plus vegetable oils became a popular cooking fat substitute in the 1970-ties. Sugar was very expensive before WWII in Poland due to special sugar tax, then became completely unavailable during German occupation 1939-1945 and then became cheap afterwards. What else other than sugar could have done the damage?
