We studied how antioxidants, particularly vitamin C, relate to reflux esophagitis and esophageal adenocarcinoma, aiming to uncover potential protective effects. Through a case-control approach involving groups with reflux esophagitis, Barrett's esophagus, and esophageal adenocarcinoma, we assessed the dietary intake of antioxidants and their relationship with these conditions.
Our findings revealed that a higher overall antioxidant intake was linked to a reduced risk of esophageal adenocarcinoma. Specifically, individuals with the highest vitamin C intake had a significantly lower risk of developing this type of cancer. However, while vitamin C also appeared to reduce the risk of reflux esophagitis, we found no strong connection between vitamin C and Barrett's esophagus, nor with other antioxidants such as vitamin E, carotenoids, zinc, copper, or selenium.
This suggests that while antioxidants could play a role in lowering the risk of esophageal adenocarcinoma, they might be more influential in terms of progression rather than initiating reflux conditions. Overall, our study highlights the potential significance of dietary vitamin C in addressing reflux issues but points out limitations when it comes to other forms of esophageal disorders.
