Vitamin A supplements are linked to lung cancer

0

A recent study has found a “causal” link between vitamin A intake and lung cancer. This is not the first time that vitamin A, also known as retinol, has been linked to cancer. However, until this study, researchers had not found an association with lung cancer.

The researchers used a Mendelian randomization (MR) method, which examines the cause-and-effect relationship between risk factors and outcomes from a genetic perspective.

The researchers found that high vitamin A intake increased the risk of squamous cell carcinoma and adenocarcinoma of the lung, two common types of lung cancer. The results showed that higher dietary retinol intake was causally associated with lung cancer, total squamous cell carcinoma of the lung, and adenocarcinoma of the lung. Dietary retinol intake has an adverse effect on lung cancer, and carotene may increase the risk of adenocarcinoma.

This highlights the importance of identifying the underlying mechanisms of dietary antioxidant vitamins in lung cancer and provides an important health message that dietary antioxidant vitamin intake may not be necessary to prevent lung cancer. It also provides a basis for future research.

More research is needed before conclusions can be drawn. Vitamin A has previously been linked to prostate cancer.
