Recent research shows lead contributes to dementia. Lead gets stored
in the
bones throughout life and when the bones start to breakdown in later
life,
the lead is released together with the calcium. This was shown
graphically
in the US government NHANES 3 study where the mid-life peak of lead
was
just as high as the childhood peak, especially in men. Lead follows
calcium
into and out of the bones. A child's lead level reflects the
environment's,
an adult level reflects their intake plus what their bones are
releasing.
Adults do digest lead less efficiently than children.

Research in Canada shows blood lead levels of men correlate with
poorer
cognitive (mental) function. Prof Needleman et al in the US have shown
that
bone lead (a measure of lifetime lead dose) in women correlates with
poorer
cotgnitive function. Prof Needleman did much of the research showing
the
harmful effects of lead on children. Now, the US has universal
screening
wwith blood tests for children in most areas.

Lead competes with calcium in calcium channel enzymes, where lead is
1,000
more times as potent (protein kinase C- a critical nerve enzyme).

A paleo diet keeps your bones strong, keeping the calcium AND the lead
locked safely way.

Does apolipoprotein E have any interaction with calcium?
