Cancer is a leading cause of
death in many western cultures, second only to heart disease. A wide array of
research bodies exist to provide solid evidence that this killer disease is
largely promoted by poor lifestyle habits, especially diet. Medical researchers
have long known that there is a definite connection between cancer and the fat
soluble vitamin E. Some studies have concluded a positive relationship between
the two, while others vilify vitamin E as a cancer progenitor.
Researchers at the Center for
Cancer Prevention Research at Rutgers University have published the result of a
study in the journal
Cancer Prevention Research that
demonstrates that vitamin E from dietary sources has a profound effect on
cancer development and progression. The scientists have found that two forms of
vitamin E, gamma and delta-tocopherols found in soybean, canola and corn oils
as well as nuts do prevent colon, lung, breast and prostate cancers.
Vitamin E from Nuts, Seeds and their Oils Provide Broad-Spectrum Protection
against Cancer
Researchers know that in the
past, studies have shown an increased risk of cancer and decrease in bone
density with vitamin E from supplements. Unfortunately, those studies either
used a synthetic form of the vitamin known as dl-alpha- tocopherol or they did
not specify the form of vitamin E used. Vitamin E exists in a variety of forms
called tocotrienols and tocopherols which occur in natural balance in many nuts,
seeds and their cold-pressed oils.
The Rutgers study author, Dr.
Chung S. Yang and his team conducted studies on animals that examined
associated risk for developing colon, lung, breast and prostate cancer. The
scientists found that the forms of vitamin E in vegetable oils, gamma and
delta-tocopherols, prevent cancer formation and growth in animal models.
Vitamin E from Natural Foods Sources and Full-Spectrum Supplementation Promotes
a Cancer-Free Lifestyle
Dr. Yang commented
“When animals are exposed to
cancer-causing substances, the group that was fed these tocopherols in their
diet had fewer and smaller tumors… when cancer cells were injected into mice
these tocopherols also slowed down the development of tumors.” Researchers
noted that studies conducted using the synthetic mono-isomer form of vitamin E commonly
used in inexpensive multi-vitamins (dl-alpha- tocopherol ) not only did not
prevent prostate cancer, but its use significantly increased the risk of this
disease among healthy men.
This study demonstrates the
importance of consuming vitamin E from natural food sources such as nuts, seeds
and their oils to benefit from the full spectrum of tocotrienols and
tocopherols, specifically the gamma and delta isomers. Dr. Yang concluded “For people who think that they need to take
vitamin E supplements, taking a mixture of vitamin E that resembles what is in
our diet would be the most prudent supplement to take.” One to two servings
of nuts, seeds or oil extracts daily (or a natural food-based supplement) are
sufficient to provide the full benefits of all vitamin E isomers shown to
significantly lower cancer risk.
