If you’ve ever made a fruit salad, you
probably know that squeezing lemon juice onto the apples, pears, and
bananas will keep the fruit from turning brown. This brown color
happens because of a process called oxidation—a reaction between the
oxygen molecules in the air and the molecules in the substance the air
meets.
A similar type of reaction happens inside your body all the time.
Substances called oxidants, or free radicals, react with your cells,
harming healthy tissue, weakening immunological functioning, speeding up
the aging process, and contributing to chronic degenerative diseases.
These free radicals are formed through normal body processes, as well as
through environmental exposure to the sun, pollution, cigarette smoke,
too much stress, and the intake of alcoholic beverages and unhealthy
food. Antioxidants
are substances that work like that lemon juice on the fruit, protecting
healthy tissue by destroying free radicals before they do any damage.
Antioxidants are believed to play a role in helping to fight and prevent
cancer, heart disease, Alzheimer’s disease, and other chronic
conditions.
So how do you get these magical antioxidants to work for you? Not surprisingly, a healthy diet full of a variety of fruits and vegetables will do the trick. But are all fruits and vegetables created equally when it comes to antioxidant benefits? Not necessarily!
