New research suggests vitamin D may help reduce the risk of colorectal cancer. A study published in the journal Nutrients analyzed data from 50 studies on vitamin D and colorectal cancer. The analysis found that women with the highest vitamin D intake had a 58% lower risk of colorectal cancer compared to those with the lowest intake. This research further confirms that maintaining optimal vitamin D levels is essential for our health.
