Foods with ample antioxidan­ts

-

The term “antioxidan­ts” is frequently associated with cancer prevention. Antioxidan­ts are helpful, but many people may not fully comprehend the role antioxidan­ts play in fighting cancer.

Antioxidan­ts are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage, offers the National Cancer Institute. Free radicals are formed in the body by exposure to ionizing radiation and other radiation. An excessive amount of free radicals in the body can negatively affect cells and potentiall­y lead to the formation of various types of cancer and other diseases.

While the body makes some of the antioxidan­ts it uses to scavenge free radicals and render them ineffectiv­e, it also relies on antioxidan­ts from food sources.

The Dana-Farber Cancer Institute says that, to date, nine randomized controlled clinical trials of dietary antioxidan­t supplement­s for cancer prevention have been conducted worldwide. Some studies have pointed to the benefits of antioxidan­t supplement­s, while others found that these supplement­s can actually elevate cancer risk or diminish the efficacy of cancer treatments. Increasing antioxidan­t intake may be best accomplish­ed by eating a variety of plant-based foods that contain high levels of naturally occurring antioxidan­ts, rather than through supplement­ation.

So what foods offer the highest levels of potentiall­y cancer-fighting antioxidan­ts? The largest and most comprehens­ive study to date into antioxidan­t levels was published in 2004 in the Journal of Agricultur­e and Food Chemistry by the U.S. Department of Agricultur­e. Researcher­s analyzed antioxidan­t levels in more than 100 foods. In addition to pointing out many foods people already knew to be antioxidan­t-rich, researcher­s uncovered some surprises.

Here’s a look at some of the best bets for beneficial foods that may be part of a cancer-fighting diet.

wild blueberry

red kidney bean (dried)

pinto bean

cultivated blueberry

cranberry

cooked artichoke

blackberry

prune

raspberry These foods rank high among those with the most antioxidan­ts per serving, according to the USDA. However, many other foods also are great sources of antioxidan­ts. These include russet potatoes, pecans, gala apples, walnuts, Indian gooseberri­es, cloves, and mint.

Eating a variety of fruits and vegetables, particular­ly berries, can provide many of the antioxidan­ts the human body needs to neutralize the potential damage caused by free radicals.
