Selenium that changed the world

Selenium-one of the most important trace elements in the world

"Selenium is one of the most important trace elements in human body."Selenium supplementation can reduce the incidence and mortality of cancer.With the further development of life science,biological scientists have proved that selenium is a rare anticancer element through a large number of scientific research and clinical practice,so people call selenium the king of anticancer.

From 1969 to 1971,Shamberger et al.,after a series of epidemiological investigations,clinical experiments and studies,pointed out that the incidence of cancer was high in low-selenium areas and people with low blood selenium,especially in digestive tract and breast cancer.

From 1985 to 1991,Chinese and American researchers conducted two randomized,double-blind,placebo-controlled population intervention trials in Lin County,Henan Province,which has the highest incidence of esophageal and cardia cancer in the world and a population with nutrient deficiencies.The results showed that supplementation ofβ-carotene,vitamin E and selenium yeast could reduce the total mortality rate by 9%and the total cancer mortality rate by 13%,especially the gastric cancer mortality rate by 20%.

From 1983 to 1996,Professor Clark of the"Arizona Cancer Center"of the University of Arizona conducted a large-scale controlled trial on 1312 cancer patients for 13 years.The results showed that the mortality rate of cancer decreased by 50%when 200 micrograms selenium was added daily,and selenium was very obvious in the prevention and treatment of prostate cancer,lung cancer and rectal cancer.Among those without cancer,the overall rate fell by 37 percent.This ground-breaking study,called the"MILESTONE of Selenium in CANCER Prevention"study,has strongly stimulated the international community to pay attention to the research and application of selenium.

Passwater famous American medical writers in this passage summarizes the professor Clark's experiment results:"a clinical study results show that selenium can make half the death rate from cancer,this is a strictly scientific standard clinical trials in humans,rather than the animal experiment was carried out in the laboratory and epidemiological studies.Since selenium levels in foods vary greatly,the only reliable way to get a protective dose of selenium is to take a selenium supplement at a known dose,which is what was used in the clinical study.

The trial yielded consistent results on cancer incidence and mortality at six of the seven sites.At a time when more and more people are becoming interested in selenium for cancer prevention,Professor LarryC Clark,director of the Epidemiology Research Group at the University of Arizona Cancer Center,and his colleagues conducted a landmark cancer nutritional prevention trial.Dr.David Alberts,Director of the Cancer Prevention Unit at the Arizona Cancer Center,commented,"There is no doubt that Dr.Clark's contribution to the use of selenium as a cancer prevention agent will have an impact on the field for decades to come."

In 1996,following Clark's pioneering selenium trial,two large population trials were started and are under way in various countries to test the theory that selenium reduces cancer.One of these,the PREISE trial,was designed to see if the results of the Clark1312 trial could be replicated and to test the theory that selenium supplementation in the general population could reduce the overall incidence of cancer.It was a randomized,double-blind,placebo-controlled cancer prevention trial involving 52,500 participants from five countries:the United States,the United Kingdom,Denmark,Sweden,and Finland.It was also called the"Selenium will Change the World"test.

The other is the SELECT trial,in which more than 32,000 people will be enrolled to see if selenium and vitamin E can prevent a higher risk of prostate cancer.

The scientific and medical circles have been working hard to fight cancer,among which the biggest harvest is the new discovery of selenium.It had been overlooked in previous studies until now,when scientists discovered its light.This light makes selenium the most dazzling star of trace elements.Selenium,which has been unknown for many years,is presented to the world with the posture of coming out of the sky.

American FAMOUS SELENIUM EXPERT,Combs OF Cornell UNIVERSITY PROFESSOR WRITES AN ARTICLE TO STATE FOR MANY TIMES,CURRENT SELENIUM INTAKE STANDARD IS FROM SATISFY HUMAN BODY BASIC PHYSIOLOGY NEEDS TO CONSIDER,BUT INSUFFICIENT AT PREVENT CANCER,PREVENT DISEASE,IF CONSIDER FROM THE Angle OF PREVENT CANCER PREVENT DISEASE,IT IS NECESSARY TO FURTHER IMPROVE THE STANDARD AND INTAKE.That means the vast majority of the world's population needs selenium supplements.

Selenium will change the world

Medical miracles have been changing the world for years.A single drop of vaccinia vaccine saved mankind from smallpox epidemics;The use of antibiotics has saved millions of lives around the world.The discovery of vitamins and hormones has greatly improved human health and quality of life.Many incurable diseases have been conquered by new technologies and drugs.Preventive medicine has freed human beings from the entanglement of diseases.Human life expectancy is increasing,all of which are attributed to the contribution of medicine.No one can deny that every new discovery in medicine is changing the world.

Could selenium,as a nutrient,surpass this miracle?If Clark's results are replicated around the world,it would mean that selenium supplementation could protect 37 percent of the world's population from cancer.And among those who already get cancer,half will avoid death.At a time when war,hunger and natural disasters threaten human life,is there anything more valuable to human beings than overcoming disease and extending life span?If selenium can do that,it stands to reason that selenium can change the world!
