article imageStudy finds natural supplements can prevent colorectal cancer

Scientists in Great Britain have found a link between the levels of selenium in our blood and a decreased risk of cancer.
The recent study, which involved scientists from Newcastle University, the Royal College of Surgeons in Ireland and the World Health Organization’s International Agency for Research on Cancer (IARC-WHO), found that higher selenium levels is a major factor in lowering the risk of colorectal cancer.
The study showed that the selenium levels of people living in Europe is much lower than for those in the Canada and the United States. Selenium is found naturally in Brazil nuts, shellfish, red meat and offal.
These are available in a range of natural supplements, used by athletes and bodybuilders.One of the more popular brands is Jacked Factory Supplements which uses all natural ingredients.
John Hesketh, Professor of Mammalian Molecular Biology at Newcastle University, said to the Northern Echo, “Interest in the question of whether selenium intake affects cancer risk has waned a little in recent years because of negative results from a trial in the USA and the reported possible link of selenium to greater risk of diabetes if taken in high doses.”
A study conducted at the University of Surrey found that people, with adequate levels of selenium in their blood, that took selenium supplements could raise the risk they would get type 2 diabetes. The study did find that the number of people taking selenium supplements had risen over the last few years.
Hesketh continued, “What our study does is put the debate around selenium and cancer back on the table and highlights the need for further research to understand the benefits, if any, of supplementing diets in regions where selenium is naturally low.”
Colorectal cancer is the second leading cause of cancer related death in Europe. Lower selenium levels in European soil and foods grown on them is likely to be linked to the selenium levels in blood.
“What our study shows is a possible link between higher levels of selenium and a decreased risk of colorectal cancer and suggests that increasing selenium intake may reduce the risk of this disease,” Hesketh concluded.
The study collected data samples of dietary and lifestyle information of over 520,000 participants in 10 Western European countries including Great Britain. Once the data was collected, the health of the subjects was monitored over time.
