According to the USDA website, www.usda.gov, chocolate and cocoa powder contain “hefty quantities of natural antioxidants called flavonoids…..antioxidants are thought to be effective in helping to prevent cancer, heart disease, and stroke.”

How do anti-oxidants help us?   “Anti”-oxidants counteract the negative effects of oxidation on our bodies.  Oxidation damages cells and tissues.  What is oxidation, you ask?

Here’s a simple example that you’re familiar with.  Think of a slice of apple turning brown shortly after you cut it.  This is discoloring demonstrates the damage that oxidation causes on the cells of the apple.  If instead of leaving the slice out in the open air, you dip immediately in some lemon juice, the brown oxidative damage slows w-a-y down.  In this case the lemon juice is the antioxidant.

Our bodies are naturally good at fighting oxidation but it becomes more difficult as we grow older.  Eating foods high in antioxidants can give our aging bodies a boost.  Research has shown that red and purple colored fruits and vegetables are rich in antioxidants, but chocolate and cocoa are among the highest in antioxidant power!

Researchers measure the effectiveness of foods containing antioxidants.  Here is a handy chart of the top five foods packing a punch.

Foods High in Antioxidants   ORAC Score*
 Unprocessed Cacao Bean    26,000
 Goji Berries    25,300
 Acai Berries    18,000
 Dark Chocolate    13,120
 Black Raspberries     7,700

* Note that numbers will vary based on sample and other factors, but generally the order remains the same.

By the way, milk chocolate comes in a little lower, with an ORAC score of 6,740.

Some studies suggest that we should eat between 3,000 to 5,000 ORAC units a day, while the average person only takes in about 1,200 ORAC units per day.

You know what that means, don’t you?  EAT MORE CHOCOLATE.  You don’t have to tell me twice!

cuoadminChocolate Milk for Exercise Recovery

By Jeffrey Kirk on June 5, 2009 | Comments (0)

Research shows that chocolate milk might be just as good as sports drinks to help athletes recover from intense exercise.  This information comes out of a small study from James Madison University in Virginia as presented at the annual meeting of the American College of Sports Medicine.
 
I like to ride my bicycle for hours at a time and have often enjoyed a glass of chocolate milk upon my return.  My logic was that the milk contained some protein so it’s probably a good thing for muscles.  Milk also contains fluid for rehydration, as well as minerals like calcium and magnesium, electrolytes such as sodium and potassium, and carbohydrates including lactose.  These are all good for recovery after exercise and occur naturally in milk.
 
During the reported study 13 soccer players were given either low-fat chocolate milk or a high-carbohydrate sports drink.  Then researchers measured blood levels of creatine kinase, an indicator of muscle breakdown.  The players who drank the chocolate milk had lower levels of this chemical, indicating less muscle damage.  Furthermore, based on measurements of players subjective reporting, there was no difference between milk and the sports drink as far as tiredness, muscle soreness, and muscle strength.
 
OK, the study was small, with only 13 players, but I think this clearly points out an alternative to expensive sports drinks.  And, this is especially good news for chocolate lovers who can now claim that their chocolate milk is a good part of their exercise program!
