Low salt diet may not be good for your heart

Another example of expert advice becoming dubious...

WEDNESDAY, June 4 (HealthDay News) — Surprising new research suggests that a diet low in salt may be worse for your heart than eating lots of salt, but don't start eating potato chips just yet.

"No one should run out and buy a salt shaker to try to improve their cardiovascular health. But we think it's reasonable to say that different people have different needs," said study author Dr. Hillel W. Cohen, an associate professor of epidemiology and population health at Albert Einstein College of Medicine of Yeshiva University.
The study, published online in the Journal of General Internal Medicine, doesn't confirm that a low-salt diet itself is bad for the heart. But it does say that people who eat the least salt suffer from the highest rates of death from cardiac disease.
"Our findings suggest that one cannot simply assume, without evidence, that lower salt diets 'can't hurt,' " Cohen said.

Finally, the FDA Warns about Mercury Fillings

NEWS ITEM: Silver-colored metal dental fillings contain mercury that may cause health problems in pregnant women, children and fetuses, the Food and Drug Administration said today after settling a related lawsuit.

COMMENT: It's about time! Health advocacy groups and holistic dentists have been saying this for years. Unfortunately, the American Dental Association has tried to silence the protests because they fear that lawsuits will follow.

Even worse, having the fillings removed carries hazards because mercury is released when the old metal is drilled out.

I had my silver fillings removed over ten years ago, a few at a time. The dentist worked carefully, using a dental dam and administering oxygen to that I wouldn't breathe in too much mercury. I still got really ill though, and didn't feel well for several months.

Warning about CFL Light bulbs

Parents and others should read the Maine Compact Fluorescent Lamp Breakage Study Report. It's from the State of Maine; their waste management bureau did extensive tests on breakage of compact flourescent lightbulbs. They still recommend using the bulbs, although after reading the warnings, I don't understand why.

After cleaning up a broken bulb, tests show "all types of flooring surfaces tested can retain mercury sources even when visibly clean."

Never vacuum up pieces of a broken CFL bulb. "Vacuuming tends to mix the air within the room such that the one foot and five foot heights are similar immediately after vacuuming. A vacuum can become contaminated by mercury such that it cannot be easily decontaminated."

Mercury is dangerous. So what do you put a broken CFL in? Turns out that plastic bags won't do; use a glass jar.
