Extra virgin olive oil has similar activity to ibuprofen
Extra-virgin
.
A recent study has shown that oleocanthal, a component of extra-virgin olive oil, has an
anti inflammatory profile and potency 'strikingly'
anti-inflammatory
strikingly similar to the nonsteroidal anti
antiinflammatory drug ibuprofen. Although the two molecules are structurally dissimilar, they
both produce a strong stinging sensation in the throat, and inhibit the same cyclooxygenase (COX) enzymes in the prostaglandin biosynthesis pathway.
Phenol compounds in newly pressed olive oils contribute to a unique balance of
flavours. One, an aldehyde derivative of deacetoxy-ligstroside aglycone (oleocanthal),

seems that this similar perception also indicates a shared pharmacological activity.
Oleocanthal acts as a natural anti-inflammatory compound with a potency and profile
very like that of ibuprofen. Is it coincidence that some of the health benefits claimed for a
Mediterranean diet, rich in olive oil, overlap with those attributed to NSAIDs?

Biologists have therefore been hoping to find some chemical or drug that would mimic caloric
restriction in people by tripping the same genetic circuitry that a reduced-calorie diet does and
provide the gain without the pain. Dr. Sinclair and his chief co
co-author,
author, Dr. Konrad T. Howitz
of Biomol Research Laboratories in Plymouth Meeting, Pa., say they have succeeded in
finding a class of drugs that mimic caloric restriction in two standard laboratory organisms,
yeast and fruit flies. Mice and humans have counterpart genes that are assumed to work in a
similar way, though this remains to be proved.
The new development has roused the enthusiasm of many biologists who study aging because
caloric restriction,, the pprocess supposedly
pp y mimicked byy the chemicals,, is the one intervention
known to increase longevity in laboratory animals. A calorically restricted diet -- including all
necessary nutrients but 30 percent fewer calories than usual -- has been found to extend the
life span of rodents by 30 to 50 percent. Scientists hope, but do not yet know, that the same
will be true in people.

research, plans to start a mouse study later in the year.

Initially non‐toxic to the body's normal cells,
Salvestrols, become activated inside human cancer cells by an enzyme, CYP1B1.
The activated Salvestrols, then cause the cancer cells to stop ,

This specificity of action is possible because CYP1B1 is an intrinsic component of cancer cells and occurs in
all of the wide range of different types of cancer that
have been studied to date,
but is to all intents and purposes absent from normal cells.
Olives are also a good source of Salvestrols. Several herbs

CYP1B1 protein is over‐expressed in
human tumours and is not specific to any
human tumours and is not specific to any
particular type of cancer – it seems to be
a feature of all cancer cells.

Leptin is produced in and secreted by the Adipocyte. It enters circulation and travels to the central nervous system where it acts on circulation
and travels to the central nervous system where it acts on
the hypothalamus to decrease the excretion of Neuropeptide Y. This serves to down regulate Neuropeptide Y causing a decrease in hunger, increase in activity, and increase in Thermogenesis, reducing energy storage and fat accumulation.
