A Doctor Says Eating This Fruit Twice A Day Can Lower Risk Of Lung And Colon Cancer: Apples

Does an apple a day really keep the doctor away? We can’t say for sure—but according to one doctor, two apples a day might help prevent cancer.

That’s right: according to physician, researcher, and bestselling author Dr. William Li (@drwilliamli on TikTok), eating just two apples a day might help lower your risk of serious diseases, including lung and colon cancer. While apples are already known for their fiber and heart-health benefits, their natural compounds make them even more impressive.

In a recent TikTok video, Dr. Li explains that apples contain potent natural substances that may help prevent cancer. These compounds, particularly quercetin, could actively block cancer-related pathways. Learn more about this advice from Dr. Li below.

According to Dr. Li, the cancer-fighting potential of apples is thanks to a few plant-based compounds that help protect your body. Quercetin, in particular, is powerful flavonoid found in apple skins. This compound offers anti-inflammatory and antioxidant properties.

Dr. Li explains that apples contain “natural substances… like quercetin, one of the natural chemicals, that actually are naturally anti-angiogenic.” Anti-angiogenic compounds help prevent the growth of abnormal blood vessels that feed cancer cells. In other words, they make it harder for tiny, early-stage cancers to develop the blood supply they need to grow.

By eating apples regularly—specifically two a day, according to Dr. Li—you may be giving your body a steady supply of these compounds. Luckily, apples are so easy to incorporate into your daily routine. Add some nut butter for a healthy fat boost and even more benefits!
