I presume that
the natural uptake by trees of selenium is what is thought here to be the
biological pathway that lowers cancer risk.
In the event it is also clear that a nut will supply any trace nutrients
that we need and eating ample nuts is clearly indicated.
It is also clear
that the market for nut meats and flours is ready to explode as consumption of
wheat is driven down. This may well be
the greatest food revolution and it is surprisingly easy to accomplish.
As I have
pointed out in this blog, growing tree lines two or more combine swathes apart
allows well-spaced trees for optimal productivity and a minimal reduction in
natural crop loss if any in fact because of natural fertilization. It also solves the pollination issue as well
with a natural nursery for wild bees as well always close by.
Large Scale
Study Shows Nuts Decrease Cancer Risk By More Than One-Third
November 21, 2013
Writing in Nature’s British Journal of Cancer, the
team behind the new analysis reported that consumption of nuts – including tree
nuts such as almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine
nuts, pistachios and walnuts – was found to be inversely associated with risk
of pancreatic cancer, independent of other potential risk factors for
pancreatic cancer.
The data, from a large-scale prospective study,
investigated the association between nut consumption and risk of pancreatic
cancer in more than 75,000 women who took part in the Nurses’ Health Study, and
had no previous history of cancer.”Frequent nut consumption is inversely
associated with risk of pancreatic cancer in this large prospective cohort of
women, independent of other potential risk factors for pancreatic cancer,”
explained the research team – led by Dr Ying Bao of Brigham and Women’s
Hospital and Harvard Medical School.
The body uses selenium to make “selenoproteins”,
which work like antioxidants preventing damage to cells. There is a growing
body of evidence to show it has a key role in health.
Bao and colleagues found that women who consumed a
one-ounce serving of nuts two or more times per week had a 35% lower risk of
pancreatic cancer when compared to those who largely abstained from nuts.
“This reduction in risk was independent of
established or suspected risk factors for pancreatic cancer including age,
height, obesity, physical activity, smoking, diabetes and dietary factors,”
said Bao.
Soil in the U.S. has higher levels of selenium due
both to different geological conditions and the fact that it’s generally more
alkaline, allowing better uptake of nutrients by plants.
Earlier this year, in a paper published in The
Lancet, she detailed selenium’s links to everything from enhanced fertility and
thyroid function to preventing plaque build-up in the arteries, regulating
blood pressure and reducing cancer risk.
Study Details
Bao and colleagues analysed data from 75,680 women
in the Nurses’ Health Study, and examined the association between nut
consumption and pancreatic cancer risk. Nut consumption was assessed at
baseline and updated every 2 to 4 years.
During the follow up, the team documented 466
incident cases of pancreatic cancer.
After adjusting for age, height, smoking, physical
activity, and total energy intake, women who consumed a 28-g (1oz) serving size
of nuts twice per week experienced a significantly lower risk of pancreatic
cancer, said Bao and colleagues – noting a relative risk of 0.65 compared to
those who did not eat nuts.
“The results did not appreciably change after
further adjustment for body mass index (BMI) and history of diabetes mellitus,”
the team added – noting that the inverse association persisted within strata
defined by BMI, physical activity, smoking, and intakes of red meat, fruits,
and vegetables.
