Dairy experts say bovine colostrum does not contain sex hormones

Hormones are ubiquitous in nature, especially in mammals, and hormones are the key to growth. And let the parents talk about the sexual hormone is sex, because children too much intake of sex hormones, it may lead to precocious puberty, physical and psychological damage to children.

The Ministry of Health on August 16th, 2010 published in its official website "The Question and Answer on Children's Precocious Puberty and Milk Estrogen" pointed out: Precocious puberty in children is a relative concept of time. It means that the age of second sexuality is higher than that of contemporaries. It is too early for people of the same race or ethnic group to have the same sex. For the moment, girls have obvious secondary sexual characteristics before the age of 8 or menarche before the age of 9. A boy with secondary sexual characteristics or a testicular volume of ≥4 ml before age 9 is considered precocious puberty. There are many causes of precocious puberty in children, such as long-term high-protein diets, effects of estrogen-like pollutants in the environment, intake of foods containing sex hormones, frequent contact with sex-related media, intracranial infections, trauma, or tumors. Diseases, various tumors and drugs that secrete sex hormones, all may cause children to become premature.

Liu Peng, director of the National Dairy Engineering Technology Research Center and director of the National Dairy Quality Supervision and Inspection Center, said that when it comes to hormones, many people are either very secretive or alarmist. In fact, it is not necessary to treat the existence of hormones. We should also have a scientific and rational attitude. Liu Peng said that in recent years, we have been paying attention to and studying the hormone problem of bovine colostrum. In 2009, the National Colostrum Collaborative Center led the establishment of the Colostrum Association, followed by bovine colostrum in many regions in Heilongjiang Province. Milk, human milk and bovine colostrum powders were monitored and compared with hormones. The results showed that the content of hormones in bovine colostrum, including estrogen, was not statistically different from that of bovine regular milk. For the same type of hormones, human milk, especially human colostrum, is also higher than bovine regular milk and bovine colostrum. I have seen reports saying that the content of estrogen in bovine colostrum is 5 to 10 times that of cow's normal milk. However, we have not found out the source of it so far.

In other words, all milks, including mother's breast milk, contain more or less hormones. This hormone is endogenous and non-exogenous. Reports have shown that the estradiol content in boxed liquid milk in China is 117-199.3±42.5ng/l, and the progesterone content is 0.49-2.81±0.4ug/l. The estrogen content in human breast milk is reported in the literature. The range of estrogen in human breast milk is 7.9-18.5ug/L, progesterone is 10-40ug/L, infant formula powder is also allowed to exist in small amounts. These hormones are all endogenous and do not affect the development of infants and young children. Affected. Bovine colostrum hormones are also endogenous and soluble in fats. During the production process, they are all removed and improved by degreasing filtration. The hormones do not exist after degreasing. Colostrum has existed in the form of commercialization in China's infant population and has been eaten for more than 20 years. The history of private consumption has been longer, and there have never been events that have adversely affected the health of infants and young children. From the point of view, the food that mammals secrete to pups is the safest, otherwise it is impossible for this species to multiply and survive for a long time, let alone evolve and develop.

The country has always had relevant hormonal tests for bovine colostrum. A food nutrition expert told the author that China's testing standards are consistent with international standards and have the most advanced detection methods in the world. The currently used stable isotope dilution liquid chromatography-tandem mass spectrometry (LC-MS/MS) is a common detection method for animal-derived food hormone residues at home and abroad for confirmation and quantitative determination. This test method was used in China to detect hormones in Olympic foods during the 2008 Beijing Olympics. It is applicable to the determination of androgens, estrogens, progestins, and glucocortisoids in animal-source foods such as milk and beef. Including the body's endogenous sex hormones and exogenous synthetic hormones. Such a high standard of detection can effectively avoid the problem of excessive hormone levels.

As a representative of New Zealand Colostrum, China Sunlight Colostrum Product, represented by China's Excellent Quality, is sent to domestic authorities for sex hormone testing each year.

As is known to all, New Zealand is one of the safest milk sources in the world. New Zealand colostrum is different from other countries in that it originates from naturally stocked pastures. There are leading technologies and processes for raw material collection and production of bovine colostrum products. From ranch to products, there is a strict guarantee and regulation system to ensure the quality of New Zealand bovine colostrum. In New Zealand, there are many studies that have proven that New Zealand bovine colostrum is safe. The National Entry-Exit Inspection and Quarantine Bureau provided relevant reports on the relevant samples provided by Life Sun Colostrum. The results showed that none of the three tests of estriol, ethylene-estradiol, and testosterone were available. Unfavorable sex hormones for your baby.
