Dear bushra

For several years we've been telling you about the advantages of selenium - a
naturally occurring mineral with powerful antioxidant properties. In e-alerts
we've told you about studies that have shown how a sufficient selenium intake
may lower the risk of prostate, breast, colorectal and lung cancers.

Now a US study from Indiana University Cancer Centre and Indiana University
School of Medicine has explored the theory that selenium activates an important
tumour-suppressing gene called p53. Scientists estimate that the p53 gene is
mutated in as much as 70% of all cancers.

In experiments performed on human lung cancer cells, the Indiana researchers
used selenomethionine, the major component of selenium, to treat cells that
contained p53 genes, and other cells that were deficient in p53. Results showed
conclusively that selenomethionine not only activated the p53 protein, but also
protected cells containing p53. Based on these findings, the researchers
speculate that selenium therapy may act as a cancer preventive by enhancing the
vitality of p53 genes. When the p53 genes function properly, cells are more
likely to repair the DNA damage that may promote cancer.

Selenium - the versatile antioxidant
**************************************************

In addition to its excellent cancer-fighting abilities, many studies have shown
that selenium's antioxidant properties may also fight autoimmune disorders and
help increase insulin efficiency. Other research has concluded that it may be
able to stop viruses from mutating and becoming more potent. US HSI Panelist Dr
Martin Milner, has used selenium for many years in his cancer protocol to reduce
the complications from chemotherapy and to increase general longevity.

Clearly, the importance of selenium in our diets can't be overstated. Plant
foods are the major dietary sources, but the amount of it in any plant depends
on the selenium content of the soil it's grown in. For instance, soils on the
high plains of North America have high amounts of selenium, while the soil in
much of China contains low amounts. Soils in the UK and Europe generally also
have low levels. So while garlic tends to contain good amounts of this mineral,
the amounts vary depending on the soil the garlic is grown in.

Selenium intake in the UK has fallen over the last 25 years and this is largely
due to the reduction in the import of high selenium wheat from North America.
The UK reference nutrient intake (RNI) for selenium is 75 and 60 ug/day for
adult males and females respectively.

Some countries experiencing a similar decline, have brought in special measures.
For example in Finland an agricultural fertilisation programme has been
implemented in order to raise cereal selenium concentrations and boost dietary
intakes. Since this programme was implemented in 1985, the selenium intake in
Finland has more than tripled and the prevalence of coronary heart disease and
some forms of cancer has fallen.

The UK reference nutrient intake (RNI) for selenium is 75 and 60 mcg/day for
adult males and females respectively. The Brazil nut is the undisputed champ,
with one ounce containing as much as 840 micrograms (mcg) - well over the
government recommended daily intake. Bread, fish, meat and eggs are also good
food sources. However, Dr. Martin L. Smith, the author of the Indiana study,
noted that the average diet probably falls short of 50 mcg per day. Furthermore,
Dr. Smith believes that in order to reap the cancer preventive qualities of
selenium, intake needs to be around 200 mcg per day.

In other words, if you can't or don't want to add a quarter ounce of Brazil nuts
to your daily diet, you might want to add selenium to your supplement regimen.
But you should also be aware that too much can be toxic. By too much, I mean an
intake of more than 2,500 mcg per day. So if you currently take a multi-vitamin,
check to see if you're already getting some amount of selenium. You may be
getting enough, but the chances that you're getting near a dangerous dose are
extremely slim.[/align]
