Vitamin D is extremely important for the body as it is responsible for calcium absorption, it is an immune system regulator and it is also believed to help reduce the risk of developing Multiple Sclerosis. One can get Vitamin D by exposing oneself to the sun or by eating Vitamin D fortified foods or eggs and fatty fish.
The study that revealed that Vitamin D helps to fight colorectal cancer was published in Gut and it is one of the many studies that have associated Vitamin D with the immune system’s response to cancerous cells inside the human body.
The third most common cancer in the US and the fourth worldwide is colorectal cancer. The CDC revealed that in 2011, 51,783 people died from colorectal cancer. The link between vitamin D and colorectal cancer isn’t new, but this study in particular has cemented the belief that Vitamin D helps to fight against colorectal cancer.
Senior author Dr. Shuji Ogino said:
People with high levels of vitamin D in their bloodstream have a lower overall risk of developing colorectal cancer. Laboratory research suggests that vitamin D boosts immune system function by activating T cells that recognize and attack cancer cells.
The scientists wanted to determine if indeed there was a way to determine if Vitamin D and colorectal cancer were connected. Were people with high levels of Vitamin D less likely to get colorectal cancer?
In order to answer this question, the researchers analyzed data from around 170,000 patients. Out of those 942 participants were selected: 624 did not have colorectal cancer and 318 did. Every single patient had a blood sample on record from before they had developed the illness. The scientists tested the blood sample for a substance the liver produced from Vitamin D.
The results showed that people with high amounts of that particular substance were less likely to develop colorectal cancer.
Dr. Ogino said that their study is the first study to clearly show the effect of Vitamin D on cancer cells, thus supporting all those lab discoveries that showed Vitamin D can raise the body’s defenses against cancer.
