Nickel - An Essential Nutrient For Red Blood Cell Health

Nickel is a relatively new addition to the micromineral family. Its
exact role in humans is unclear but the available research suggests
that it helps the body absorb iron, produce red blood cells and much
more. In this article I will be discussing this nutrient in greater
detail and providing you with a summary of its main functions, the
best food sources, the recommended daily allowances (RDAs) and the
potentially adverse effects of consuming too much or too little.1)
DISCOVERY:Awareness of nickel dates back to ancient times. However,
when early miners came across this element they were confused by it
because it was very similar to existing metals (such as copper) but
reacted differently when exposed to heat. This confusion was cleared
up in 1751 when the Swedish mineralogist Axel Fredrik Cronstedt
studied these metal ores and recognised that nickel was a new
element.2) FUNCTION:There is relatively little research available on
the effect nickel has on humans. However, it is believed to have a
number of roles in the human body which include activating certain
enzymes, helping the body absorb iron, promoting healthy metabolism
and supporting the production of certain hormones. On top of this
nickel is thought to assist in the production of red blood cells, keep
your skin healthy, promote good bone structure and support optimal
growth.3) RDA:Since there is little research available on nickel no
RDA has been established. However, most sources suggest that consuming
0.1 milligrams (mg) per day is adequate and consuming up to 100mg per
day is safe.4) FOOD SOURCES:There is only limited research available
on the concentration of nickel in foods. However, almonds, brown
beans, chickpeas, hazelnuts, oats and walnuts are all considered rich
sources of this nutrient.5) OVERDOSE SYMPTOMS:Overdosing on nickel
from diet alone is almost impossible. However, inhalation of nickel
fumes can lead to an overdose for which the symptoms include high
blood pressure, an increased lung cancer risk, an increased risk of
infection, reduced bone development, a reduced growth rate and skin
rashes. Approximately 10% of the UK population are thought to be
allergic to nickel and these people may experience the same negative
symptoms listed above even when consuming low amounts of this
nutrient.6) DEFICIENCY SYMPTOMS:Failing to consume enough nickel is
very rare because it is required in such small amounts and currently
there are no negative symptoms associated with deficiency.
