Vitamin D Slashes Colorectal Cancer Risk by 58 Percent: Study Finds
A recent study published in the journal Nutrients has revealed that adequate intake of vitamin D may reduce the risk of developing colorectal cancer by up to 58%. This significant finding adds to growing evidence suggesting that vitamin D, known primarily for its role in bone health and immune function, also plays a crucial role in cancer prevention.
Colorectal cancer, which includes both colon and rectal cancer, remains one of the most common types of cancer worldwide. Researchers have increasingly turned their attention to nutritional factors in cancer prevention, with vitamin D emerging as a leading candidate due to its widespread effects on immunity and inflammation.
In the Nutrients study, scientists analyzed data from 50 studies involving individuals with colorectal cancer, those deficient in vitamin D, and those taking supplements. The analysis found a clear link between low vitamin D levels and an increased risk of colorectal cancer. Researchers found that those with the highest dietary intake of vitamin D (80 ng/mL) had a 25% decrease in colorectal cancer risk compared to those with the lowest amount (10 ng/mL). The findings are consistent with previous large-scale studies.
