We are exposed to free radicals every day, and they have a role in heart disease and cancer. These damaging free radicals are byproducts of our own body’s metabolism and exposure to sunlight, cigarette smoke and various other carcinogens. Fortunately, they are reduced by antioxidants.
I support natural antioxidants that can be found in wholesome, unprocessed food. I’m generally against any artificial man-made supplements that claim to be antioxidants when a natural antioxidant food source is available. So for me, it is blueberries before blue pills.
High dose supplements rich in beta-carotene, vitamin A, and vitamin E have been associated with health risks. according to Mayo Clinic. There have been no reportable concerns regarding the safety of natural foods high in antioxidants.
So in general, fruits and vegetables along with their juices plus whole grain products, nuts, seeds, herbs and spices are your best sources of antioxidants. They help reduce damaging free radicals that we are naturally exposed to in the environment especially those from bad habits such as too much smoking or sun exposure.
WHAT ARE ANTIOXIDANTS?
Antioxidants are substances that may protect your body’s cells against the effects of free radicals — molecules produced when your body breaks down food or is exposed to tobacco smoke and radiation. Free radicals may play a role in heart disease, cancer and other diseases.
Antioxidants, such as vitamins C and E and carotenoids, may help protect cells from damage caused by free radicals. Other naturally occurring antioxidants include flavonoids, tannins, phenols and lignans. Plant-based foods are the best sources. These include fruits and vegetables and their juices, whole-grain products, nuts, seeds, herbs and spices, and even cocoa.
As a bonus, fruits, vegetables and whole grains high in antioxidants are also typically high in fiber, low in saturated fat and cholesterol, and good sources of vitamins and minerals.
So grab a peach or apple and do something important for your body!
