anticarcinogens การใช้

• The report also called for more research on natural anticarcinogens.
• The committee pointed out that little was known about the interaction of carcinogens and anticarcinogens in foods.
• Anticarcinogens that may help prevent cancer can also be found in many food especially fruits and vegetable.
• Three years later, the National Research Council is much more cautious in its study, " Carcinogens and Anticarcinogens in the Human Diet ."
• In addition to substances naturally present in cows'milk fat, Parodi noted that dairy cows extracted other potential anticarcinogens from their feed and transferred them to milk.
• Studies of different groups of people with different diets have strongly suggested that in a diet rich in fruits and vegetables, anticarcinogens are far more influential than natural and synthetic carcinogens.
• In theory, anticarcinogens may act via different mechanisms including enhancement of natural defences against cancer, deactivation of carcinogens, and blocking the mechanisms by which carcinogens act ( such as free radical damage to DNA ).
• For example, broccoli contains arsenic, a carcinogen, and chlorogenic acid, which is converted in the body to caffeic acid, but it also has anticarcinogens : vitamin C, sulforaphane, indole and other isothiocyanates.
• It is however often difficult to identify the specific components in diet that serve to increase or decrease cancer risk since many food, such as beef steak and broccoli, contain low concentrations of both carcinogens and anticarcinogens.
• It is also able to conjugate major classes of drugs such as analgesics ( morphine ), carboxylic nonsteroidal anti-inflammatory drugs ( ketoprofen ), and anticarcinogens ( " all-trans " retinoic acid ) . which has analgesic effects less potent than morphine.
• The report, " Carcinogens and Anticarcinogens in the Human Diet, " based on an exhaustive review of scientific reports and other relevant information, said that about a third of the 1.35 million new cancer cases in the nation each year could be traced to diet, but probably not to natural or synthetic chemicals in significant numbers.
