Supplementation of diets with alpha-tocopherol reduces serum concentrations of gamma- and delta-tocopherol
Seeds from Japan and China had a 10% greater delta-tocopherol
concentration, while seeds from Korea had a 7% higher gamma-tocopherol concentration.
Washington, Apr 24 ( ANI ): 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, according to a new study.
The combination of gamma-tocopherol and other forms of E (e.g., delta-tocopherol
and gamma-tocotrienol) performed even better than gammatocopherol alone.
It has gained tremendous popularity in recent years, since medical research confirmed the nutritional benefits of walnuts--supporting the Chinese view of walnuts as a "brain food." Walnuts are also the best source of delta-tocopherol
With respect to vitamin E, the SELECT trial used pure alpha-tocopherol, whereas vitamin E occurs in food in 4 different forms (alpha-, beta-, gamma-, and delta-tocopherol
Combining gamma with other forms of E (e.g., delta-tocopherol
, gamma-tocotrienol) was even better at blocking cancer than gamma-tocopherol alone.
gamma-, beta-, or delta-tocopherol
, plus a flavonoid and lactoferrin.
Vitamin E, in the form of gamma-and delta-tocopherol
, specifically scavenges reactive nitrogen species.
