February is Cancer Prevention Awareness Month. Here at the Abramson Cancer Center, we are committed to providing outstanding comprehensive cancer care and cancer information including ways to prevent cancer. Further, cancer researchers at Penn are at the forefront of learning new ways to prevent and detect cancer.

In this article, dietitian Carly Roop, RD, discusses foods that can lower your risk of lung cancer. Carly is a registered dietitian at the Joan Karnell Cancer Center (JKCC). She provides nutrition education and support to patients while addressing nutrition-related side effects from chemotherapy and radiation.

What is the healthiest thing to eat when trying to prevent lung cancer?

When thinking about cancer prevention, many people want to know, "What is the healthiest thing to eat?" 

The American Institute of Cancer Research found compelling evidence that a diet high in fruit can lower lung cancer risk as much as 36% of those U.S. lung cancer cases not caused by tobacco. The AICR recommends eating at least 5 servings of a variety of fruits and vegetables every day!

This may seem hard to do, but the AICR makes it easy by suggesting you rethink your plate.

As a dietitian, my mantra is food first; there is convincing evidence that high-dose supplements of beta-carotene can actually increase lung cancer risk. Therefore, it is better to get your beta-carotene from vegetables such as carrots, pumpkin, and sweet potato.

In the food form, the phytochemical beta-carotene neutralizes free radicals, which may damage cells. The anti-cancer compounds found in cabbage and kale such as indole-3-carbinoles and isothiocyanates have also been linked to a lower incidence of lung cancer.

Sauerkraut anyone?
