Rutgers Study: Vitamin E in Diet
Protects Against Many Cancers
But the Vitamin E in commonly used
supplements doesn't provide the same benefits.
Next time you need to choose between vegetable
oil and margarine in that favorite recipe, think about your health and reach for
the oil, and add those dark green leafy vegetables.
While the question of whether vitamin E prevents or promotes cancer has been
widely debated in scientific journals and in the news media, scientists at the
Center for Cancer Prevention Research at Rutgers Ernest Mario School of
Pharmacy, and the Cancer Institute of New Jersey, believe 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.
are studies suggesting that vitamin E (supplementation) actually increases the risk of cancer and
decreases bone density," says Chung S. Yang, director of the center. "Our
message is that the vitamin E form of gamma-tocopherols, the most abundant form
of vitamin E in the American diet, and delta-tocopherols, also found in
vegetable oils, are beneficial in preventing cancers while the form of vitamin
E, alpha-tocopherol, the most commonly used in vitamin E supplements, has no
Yang and his colleagues summarized their
findings recently in Cancer Prevention Research, a journal of the American
Association for Cancer Research. In a Commentary, "Does Vitamin E Prevent or
Promote Cancer?" the Rutgers scientists discuss animal studies done at Rutgers
as well as human epidemiological studies that have examined the connection
between vitamin E and cancer. Yang says Rutgers scientists conducting animal
studies for colon, lung, breast and prostate cancer found that the forms of
vitamin E in vegetable oils, gamma and delta-tocopherols, prevent cancer
formation and growth in animal models.
"When animals are exposed to cancer-causing
substances, the group that was fed these tocopherols in their diet had fewer and
smaller tumors," Yang says. "When cancer cells were injected into mice
these tocopherols also slowed down the development of tumors."
In researching colon cancer, Yang pointed to
another recently published paper in Cancer Prevention Research, indicating that
the delta-tocopherol form of vitamin E was more effective than other forms of
vitamin E in suppressing the development of colon cancer in rats. This is good
news for cancer research. Recently, in one of the largest prostate cancer
clinical trials in the United States and Canada, scientists found that the most
commonly used form of vitamin E supplements, alpha-tocopherol, not only did not
prevent prostate cancer, but its use significantly increased the risk of this
disease among healthy men.
This is why, Yang says, it is important to
distinguish between the different forms of vitamin E and conduct more research
on its cancer preventive and other biological effects.
"For people who think that they need to take
vitamin E supplements," Yang says, "taking a mixture of vitamin E that resembles
what is in our diet would be the most prudent supplement to take."
"mixture of vitamin E that resembles what is in
our diet" perfectly describes Juice Plus+.
So, it's no surprise that the University of Texas MD
Anderson Cancer Center, Houston, TX recently published a Juice Plus+ study in the March 2012 issue of the
Gynecologic Oncology Journal.
This is the 24th Juice Plus+
study to be published and clearly demonstrates the nutritional benefits of adding Juice Plus+ capsules and the
Plus+ Complete whole-food based drink mix to a healthy diet for ovarian cancer patients. To learn more about the published
