1776 Scientific Belief

I like keeping up on the latest pronouncements from science. Because science is always updating. One thing that a lot of folks--- especially those who like to see the world in immutable black and white terms---don't get is that science is never totally right. It's always changing and updating as new facts come it. Facts actually change based on available information.
It's beliefs that are hard to change.
Like recently, the Mayo clinic reported that too much exercise is bad. Marathoners and anyone that puts in more than an hour of intense aerobic activity a day have a heightened risk of irregular heartbeat, clogged arteries, and scarring.
As in everything, moderation is key.
Just like I've always believed.
And now it seems that whole thing about salt being bad for your heart is wrong. In fact, if you restrict yourself to the super low doses recommend by the FDA, you may actually damage you heart.
How could that happen? How could they be so wrong? From science based on the fact that high salt temporarily increases blood pressure because it causes fluids to accumulate in your system and your kidneys briefly overwork to deal with it. But there was never any follow-up proof to determine if that became a chronic condition.
Oops.
It also turns out our obesity epidemic isn't caused by high fat food. It's caused by too much sugar being used in low fat food to replace the flavor lost when removing the fat. The extra sugar in our system is converted to bad fat surrounding our internal organs and causes heart disease and clogged arteries.
Since the bulk of that sugar comes from high fructose corn syrup these days my sister Merry pointed our we should call it corn-ary heart disease.
I believe I agree with her.
America, ya gotta love it.
