According to Dr. Greger, the founder of nutritionfacts.org, there is some actual evidence pointing towards the healthy benefits of dates and its ability to prevent colon cancer. Dates have been proven to hold powerful medicinal properties, and some studies have suggested that dates contain potent anti-cancerous nutrients. This comes down to a few different factors, but some of them are the high levels of prebiotics that dates contain. This contributes to good gut flora, which is really important to avoid cancer. Furthermore, some studies have shown that dates could help to minimize cancer growth down to half.
