Top 5 Cancer Fighting Foods

To be clear, no food has the ability to kill cancer completely. However, there are many ‘cancer-fighting foods’ that can lower your risk of cancer. Most ‘cancer-fighting’ foods contain phytochemicals. These are chemicals found in plants that help prevent chronic diseases, like cancer. I’ve included a list of five of the top “cancer-fighting” foods, as well as three foods you should stay away from.


5 Foods That Help Prevent Cancer
  • Examples: Blueberries, blackberries, raspberries, strawberries
  • Rich in vitamins C & K, minerals, dietary fiber, elegiac acid, antioxidants, polyphenols, and manganese.
  • Cancers they fight: skin, bladder, lung, breast, esophageal.
  • Studies show that blueberries can prevent the growth of breast cancer tumors. Another study showed that blackberries lowers the chance for colon cancer. 
  • Pro tips: berries are an easy addition to yogurt, smoothies, and cereals!

Cruciferous Vegetables

Stay Away From

There are certain foods that can actually increase your chance of cancer. Steer clear of these foods when you’re putting together your weekly grocery list!

Processed Meat

These include hot dogs, bacon and most meats found at the deli counter. Steer clear- these all have compounds that can cause cancer! The World Health Organization says that processed meat is classified as a carcinogen.

The article states, “Twenty-two experts from 10 countries reviewed more than 800 studies to reach their conclusions. They found that eating 50 grams of processed meat every day increased the risk of colorectal cancer by 18%. That’s the equivalent of about 4 strips of bacon or 1 hot dog. For red meat, there was evidence of increased risk of colorectal, pancreatic, and prostate cancer.

Red Meat

Let me clarify- red meat is OK when eaten sparingly. This means no more than 18 ounces of cooked red meat per week. Still craving meat? Healthier alternatives include lean chicken, fish, or plant-based protein. Here is an easy plant-based recipe you can try adding into your meal rotation!


The less alcohol, the better. However, it is nice to have a drink every now and again. As a rule, women should limit themselves to one drink per day, and men should limit their alcohol to two drinks a day, at most. 

If you are considering making some changes to your lifestyle, remember drastic changes don’t necessarily always mean long-lasting changes. A good rule to live by is: everything in moderation.
