A new study by experts from Harvard University of America found that people who took vitamin D supplements on a daily basis may be less likely to develop advanced cancer and even fatal cancer, and researchers found that people who taking pills daily were 17% less likely to develop advanced cancer. % And those of a healthy weight would likely have benefited, with a 38% risk reduction.
According to the British newspaper “Daily Mail”, researcher Dr. Paulette Chandler, primary care physician and epidemiologist at Brigham and Women’s Hospital in Boston at Harvard University, said: “Vitamin D supplement is readily and cheap. available and has been used and studied for decades and the results we have achieved, especially the strong risk reduction seen in For individuals of normal weight, provides new insights into the relationship between vitamin D and advanced cancer. “
More than 25,000 people participated in the study, which lasted more than five years.
Participants included men aged 50 or older and women aged 55 or older who did not have cancer at the start of the study.
The test subjects were divided into four groups: the first group took a daily dose of vitamin D and omega-3s. The second group took vitamin D in addition to a placebo, while the third group took omega-3s in addition to a placebo, while the fourth group took only placebo drugs..
Initial results showed no statistical differences in overall cancer rates, but a decrease in cancer-related deaths was observed..
In their secondary analysis, Dr. Chandler and colleagues assessed the risk of developing advanced cancer – advanced stage and metastatic forms of the disease – among participants who took or did not take vitamin D supplements during the study..
They also looked at whether an individual’s BMI played a role.
Among the participants, 1,617 people were diagnosed with invasive cancer – such as breast, prostate, colon, rectal and lung cancer – over the next five years..
Of those who received vitamin D, 226 were diagnosed with advanced-stage cancer, compared with 274 who received a placebo..
Of those with a healthy weight who took vitamin D, 58 people were diagnosed with advanced cancer compared with 96 people who took the placebo..
The team said they found no association between omega-3 fatty acid supplementation and advanced cancer.
Researchers believe that obesity and associated inflammation may reduce the effectiveness of vitamin D..
Dr Chandler said: “ Our findings, along with the results of previous studies, support the ongoing evaluation of vitamin D supplementation for the prevention of metastatic cancer, a biologically plausible link..
Further studies focusing on cancer patients and investigating the role of BMI are warranted.
Like Harvard University, most vitamin D and cancer research shows a link between people getting enough vitamin and have lower rates of disease, less severe cancers, and a reduced risk of dying from the disease.
In laboratory studies, putting vitamin D against cancer cells has been shown to reduce their growth and prevent them from multiplying and spreading..
