Why Might Vegetarians Have Less HPV?
"Why Might Vegetarians
Have Less HPV?" Cervical cancer is now considered a
sexually transmitted disease, originally suspected as such
as it was supposedly found less in nuns and
more in prostitutes, but now we have DNA fingerprinting
proof that virtually all cervical cancer is caused by a sexually transmitted virus,
human papilloma virus, which also causes cancers of the penis,
vagina, vulva, and throat.
HPV is considered a necessary,
but not sufficient cause of cancer. Most young women contract HPV,
but most don't get cervical cancer, because their immune systems
are able to clear out the virus. 70% of women clear the infection within
1 year and more than 90% within 2 years before the virus can
cause cancer, unless you're immuno-
compromised or something. Well, if that's the case, may
maybe those with particularly strong immune systems
might clear the virus even faster. That's what may be behind this new
study that found that vegetarian women appear to have significantly
lower infection rates with HPV.
It's one of many studies reporting
that vegetarians have lower risk of HPV infection thought to be because of the presence of more fruits
and vegetables in their diet, which are rich sources of
all sorts of good phytonutrients. So for example, if you take a bunch
of women with cancer-causing strains of HPV infecting
their cervix and follow them out,
and retest at 3 months, and then 9 months, while analyzing
their diets, what do you find? Higher levels of vegetable
consumption may cut the risk of HPV
persistence in half, double one's likelihood of clearing this
potentially cancer-causing infection. And "higher" levels just meant
like 2 or more servings a day! What do antioxidants in plants
have to do with viral diseases? Different antioxidants affect
different viruses in different ways, but against HPV…don't you know that electrophoretic
mobility super shift assays showed "irrespective of enhanced c-fos
expression, c-jun was phosphorylated and became primarily
heterodimerized with fra-1", "which was also induced
after PDTC incubation"…I mean duh! I had to read this
paper like 5 times! Long story short: antioxidants
appear to suppress the activation of critical segments
of the virus' DNA.
Maybe that's why smearing green tea
on genital warts – also caused by HPV – has been found so effective
in clearing them. In terms of preventing cervical cancer:
through their role as antioxidants, pytonutrients like lutein, found
in dark green leafy vegetables; and lycopene, the red pigment in
tomatoes, may decrease viral load, thereby decreasing persistence
and progression to disease. Whereas the protective associations
may be due to their antioxidant properties. They have all sorts of other wonderful
effects, so who knows… who cares! Bottom line: "higher
consumption of vegetables may decrease risk
of HPV persistence," which may help explain
why this 2013 study found vegan women
have significantly lower rates of all female cancers combined,
including cancer of the cervix.
