[]: Today, you drink milk? if you answered "Yes", your risk of cancer has increased, some of the latest research data will tell you, this is why.
Before, people think that is a weaning the baby to drink, and without security, soft drinks, adults will not cause harm. But in the past 10 years, scientists through in vitro testing and (adult) human testing found that the milk can substantially increase adult males suffer from prostate cancer risk, while for women, drinking milk may be suffering from breast and ovarian cancer. Milk and cancer links? what scientists think that the carcinogenic factors may be the milk of hormones, growth factors and other bioactive chemicals.
United States Cancer Institute scientists in a new study, also found some evidence. Timothy · where Costa (Veenstra) and colleagues from shopping malls to buy 15 kinds of milk, the analysis found that actually contains 15 female hormone: the female hormone ketone (estrone), estradiol (estradiol) and the other 13 types of the metabolism of the female hormone derivatives.
Typically, the secretion of hormones in the human body is to regulate the physiological functions, they like the band Commander, regulation of the gene expression to open or to terminate. However, if the body contains a hormone (not the body's own production), it may interfere with the functions of the human body.
Estrogens may promote tumor growth, particularly in the prostate — surprisingly, even very low estrogen concentrations, can also play a role. Estrogen concentrations in different kinds of milk-what changes, what chemicals will form the estrogens?
United States Cancer Institute scientists in research to answer the above questions (related research will be published in the latest issue of the journal of chromatography B Bulletin). They found that the full-fat milk contains a minimum of estrogens, concentration in about 2%, skimmed milk and cream in the concentration is higher.
In most of the chemical structure, estrogens are some change has occurred, the biological activity of all. However, this does not mean that the female hormones in milk does not have an impact on the human body — sometimes, these hormones will change to their original form. Scientists also pointed out that, unlike with biological activity of hormones, hormone changes occur in the human body in longer, thus sufficient time from gastrointestinal tract into the blood circulation. Where Costa research team confirmed that the altered half-life of female hormones than indeed change has been prolonged.
United States Cancer Institute of Toxicology home xuxia (Xia Xu) said: "in General, skimmed milk low estrogens in the original, but other forms of female hormones is relatively more. In particular, 2-hydroxy estrone (2-hydroxyestron), female hormone derivatives, the substance of the reactivity of the highest, most powerful carcinogens. "In all milk, skimmed milk of 2-hydroxy estrone concentrations ranked second, behind only the cream.
