Un nuevo mundo a explorar si hablamos de los Tocotrienols: http://www.palmnutraceuticals.com/vite.htm
In order to have 50 mg equivalent of tocotrienols, one has to consume about 81 g of crude palm oil, 345 g of rice bran oil or ranging from one to three kg of cereals/grains per day. A recent study indicates that fruits and vegetables contain very little tocotrienols and even larger daily consumption is needed in order to achieve 50 mg equivalent of tocotrienols. Even at that large quantity of food intake, the bioavailability of tocotrienols is expected to be depressed significantly by the presence of tocopherols.
Tocotrienols are essential for chemoprevention of degenerative diseases. Currently perceived “balance diet” is unachievable, in terms of tocotrienols.
Global annual production of palm oil exceeds 40 million tons whereas that for rice bran oil is only 3 million tons, out of which 2 million tons are unsuitable for human consumption. Therefore palm oil is the best and most reliable natural source for tocotrienols. Although palm oil is the best natural source for tocotrienol, it contains too high α-tocopherol, causing the tocotrienol-rich fraction extracted from palm oil to be far from ideal. However, appropriate processing technology can reduce the α-tocopherol content in tocotrienol-rich fraction.
Down-regulation of telomerase activity in DLD-1 human colorectal adenocarcinoma cells by tocotrienol : http://www.sciencedirect.com/science/ar … 1X06015658
The telomerase lengthening in normal cells and shortening in cancer cells appears to be attributed more to delta tocotrienols.
However, the bulk of the anticancer action of tocotrienols is attributed more to gamma tocotrienols.
The National Cancer Institute studied 29,000 Finnish men for 5 to 8 years, all long-term smokers and older than 50, and gave some of them vitamin E and beta-carotene, and some of them nothing. The results?Those who took vitamins and supplements were more likely to die from lung cancer or heart disease.
