Anti-Cancer Foods

At some point you have probably read a reference to “super foods” that can be eaten to help prevent cancer. However, most nutrition and cancer experts will tell you that no single food will prevent cancer.

Foods — and humans — are complex. Foods contain many chemicals. And, our interaction with the food we eat is not a simple, purified version of a chemical mixing with cells in a test tube.

“There are food groups and some specific foods that probably lower the risk of cancer,” says McLeod Oncologist Dr. Rommel Lu. “And, some elements in food can convincingly lower the risk of a specific type of cancer.”

ANTI-CANCER FOODS & SUBSTANCES

ANTIOXIDANTS are compounds that can block chemicals in the body, called free radicals, which damage cells and can lead to cancer. Foods that are high in antioxidants include:

  • Blueberries (rank among the most powerful antioxidant fruits)
  • Apples
  • Coffee
  • Tomatoes
  • Beans
  • Dark, Green Leafy Vegetables, such as spinach, kale and romaine or arugula lettuce.

SULFORAPHANE appears to impair cancer stem cells. The following vegetables contain this component:

  • Broccoli and broccoli sprouts
  • Brussels sprouts
  • Cabbage

RESERVATROL can, at best, cause cancer cells to self-destruct or slow their growth.

  • Grape skins, particularly red grapes, contain this substance.

Some foods reportedly help prevent specific types of cancer:

  • Whole grains (bread, pasta, cereal) and food with high fiber can lower the risk of colon cancer.
  • Fish can reduce the risk of colon cancer by a third, if it’s eaten for one meal a day.
  • Foods with strong flavor (onions, garlic) contain chemicals that seem to accelerate repair of damaged DNA and neutralize cancer-causing elements.

FOODS TO AVOID

Research shows there are some foods that can increase your risk of cancer.  Among those “bad” foods are:

  • Red Meat, especially if it’s well done or charred.
  • Processed meats, such as hot dogs, bacon, sausage, salami and pepperoni.  Eating a lot of processed meat will increase your risk of stomach, pancreatic and colon cancer.
  • Potato chips and French Fries may contain a cancer-causing substance formed when foods are heated to high temperatures.

FINAL THOUGHT

Although researchers point out the benefits of certain foods, eating any one food isn’t likely to have a huge impact on your cancer prevention efforts.

A healthy diet, one that includes many of the anti-cancer foods, is the best way to keep your body and cells healthy.

An apple a day — along with some fish, nuts, whole grains, onions, grapes and broccoli – can help keep the doctor away.
