The decline in heart disease deaths in the USA since 1970 has fascinated me. I have studied this trend and potential contributors.
All in all, I think its multi-factored between medical advancements, changes in social behaviors like smoking, and environmental.
Some of the changes were so gradual, people forget exactly what it was like living back in 1968 when heart disease peaked at an all time high.
I examine those changes. All positive changes that impact our lives for the better, but are taken for granted by the younger generations because they were not around back then.
Granted it involves theory as its related to heart disease. Many resist outside the box thinking. But these positive changes were real, and heart disease declined hand in hand as these changes occurred. The only remaining question is, did these factors contribute to the decline?View Thread
On the weight issue I can't speak for others, but for myself I find eliminating bread and flour products has a huge impact on losing weight. If I make no other changes, just eliminate bread, off comes the pounds.View Thread
It would also be interesting to know which counties experienced the decline.
Back in 2002 while vacationing in Gulf Shores Alabama, I was stunned to walk into a restaurant to find people smoking. I asked for non-smoking and the host said " We don't have non smoking" The scene reminded me of the 1960's.
Sure enough, In 2002, laws for that area had yet to be passed against smoking in public buildings. They have since been passed and the area has progressed.View Thread
That is good news. One possible contribution may be tighter restrictions on second hand smoke in public places.
I have seen reports that when stricter smoking laws go into effect for a city or county, admissions to local hospitals for chest pain and heart attack notably drop, and the change is recognized almost immediately after the laws are passed.
The world has changed a lot since 1970 when the decline started. It's great to see the decline continue.
People think I'm nuts when I cite modern day central heat and air playing a role in the decline of vascular disease after 1970.
Few people had central air before 1970, if they had A/C at all. The growth of central Air coincides with the decline in heart disease in the US. Of course association doesn't prove causation, but there may be a link.
We know that heart attacks are more likely to occur in extreme temperature conditions, hot or cold. But it may go beyond that.
Central A/C cleans the air. Not just the main dust filter, but thru condensation on the evaporator coil taking out the fine particulate and sending it out the drain pipe in a trickle of water.
Cleaner, dryer, more dense air is inhaled by the occupants, improving artery health.
