We have a conventional belief that Vitamin D and calcium along with maintaining the bone health in elderly people also prevent the development of cancer. But a recent study has claimed that Vitamin D and calcium no doubt prevent bone fractures although they are not helpful in preventing cancer. Some of the previous researches claimed that Vitamin D and calcium together are capable of fighting cancer. But recently some of the researchers have rejected the previous view.
Dr. Michael Pollak, the head of the cancer prevention at McGill University in Montreal, Canada, although did not take part in the aforementioned study has mentioned that the findings of the study has shown that all the micronutrients are quite disappointing. He has also declared Vitamin D, the best micronutrient to be disappointing in the same way.
The new report has been appeared in the Annals of Internal Medicine. The mentioned work has combined total 19 previous studies about the health benefits of Vitamin D with or without calcium. The time duration of the studies varied from 7 months to 7 years. The total 19 studies involved a few thousand participants to ten thousand participants. A very small number of studies among them showed that women who took vitamin D and calcium together got protection against cancer but most of those studies showed no benefit.
In the last month a study regarding almost the same topic was published in the Journal of Clinical Endocrinology and Metabolism. The study was conducted over some elderly people taking 800 IU of vitamin D daily. After some years of study the researchers found that 32 out of 100 people who took the vitamin D and calcium died during the study and 33 out of 100 people who did not took vitamin D and calcium also died.
Although the study findings are not included in the aforementioned work, Chang the lead researcher of the work has claimed that Vitamin D and calcium together do not make any difference to cancer development.
