Good news!! Antioxidants are the natural defense system in our body.
What does the term Free Radical mean?
Without getting too scientific, oxygen molecules that split into single atoms have no paired electron. These solo atoms, known as free radicals, can bind with other electrons. There are many types of free radicals. However, too many unstable free radicals is called Oxidative Stress, which ultimately damages our DNA and may promote disease.
Symptoms of Oxidative Stress
There is not an actual “disease” called Oxidative stress but some of the recognized symptoms include fatigue, headaches, noise sensitivity, memory loss and brain fog, muscle and joint pain, 
wrinkles and gray hair, vision trouble and decreased immunity.
What are some examples of free radicals?
Sugary drinks, processed foods and meats, and excess chips and desserts are some examples of foods. However, environmental pollutants, pesticides, cigarette smoke, some medicines, and even “weekend warrior exercise” are also examples of free radicals.
Changing our Choices
Most of us are apt to choose high in the free radical choices and low in anti-inflammatory, antioxidant selections. Let’s change this. Antioxidants include fruits and berries with deep colors, including cherries, dark green leafy lettuce, and sweet potatoes, Turmeric, cinnamon, ginger, and green tea also have natural antioxidants, as do some treats such as vanilla beans, dark chocolate, and red wine. Plant-heavy diets can also promote gut, brain, heart, and mouth health. If you decide to boost oral health through dark chocolate and red wine, do so in moderation.
So, skip the chips, and pass the berries!
