Making Smart Food Choices to Reduce Cancer Risk
As we begin the new year, many people might be thinking about improving their diet and overall health.

While there’s a lot of conflicting nutrition information online, the evidence-based answer that a diet rich in plant-based foods can help reduce your cancer risk.
A plant-based diet doesn’t mean you have to become vegetarian or give up all animal products. It means making fruits, vegetables, whole grains, beans and other plant foods the focus of your meals, while treating meat and dairy as supporting players.
Here’s what you need to know about eating for cancer prevention:
- Plant foods are powerful cancer fighters. They contain natural compounds called phytochemicals and antioxidants that work together to keep our cells healthy and protect them from damage. Colorful fruits and vegetables are especially rich in these protective compounds.
- A plant-based diet helps maintain a healthy weight. Excess body weight increases risk for several types of cancer, and plant foods are naturally low in calories and high in fiber while being filling and satisfying.
- You don’t have to give up meat entirely. This approach is flexible – you can still enjoy lean proteins like chicken, fish, eggs and low-fat dairy. The key is to fill most of your plate with plant foods first.
The most important thing to remember is that you don’t have to make perfect choices all the time. Even small improvements to your diet can help reduce your cancer risk over time. Here are some simple, small changes that can make a difference:
