Apple A Day Boosts Immunity

That old saying, 'An apple a day keeps the doctor away' was put to the test by University of Illinois researchers looking to pinpoint the fruit's healthy mechanism. They fed two groups of lab mice low-fat diets. One group's food was rich in soluble fiber while the other group's diet emphasized insoluble fiber. Just 6 weeks later, scientists introduced an illness to both groups. The soluble fiber eaters got only half as sick and recovered in half the time it took the insoluble fiber-fed rodents to get well. Results will be published in the May 2010 edition of the journal Brain, Behavior & Immunity.

True Strength Moment: The soluble fiber found in apples, whole grain oats and nuts increases production of an anti-inflammatory protein known as interleukin-4. As a result, immune cells are able to speed our recovery from infections. Get your fair share of soluble fiber so you can keep working harder, longer and stronger toward achieving impressive goals.
