Amazing Antioxidants

The prefix ‘anti’ means against, in opposition to, or corrective in nature. In this case, the ‘anti’ in antioxidant describes the effect these chemicals have against oxidants.  

Oxidants, usually referred to as ‘free radicals’ are produced as a natural by-product of the millions of biochemical processes undertaken by the body every minute. The same life-giving oxygen that supports all the functions of the body creates these harmful by-products which cause cell damage, usually to DNA, fats and proteins.  

Free radicals also enter the body through external influences such as exposure to the sun, pesticides and other kinds of environmental pollution. In addition, their levels are increased by mental and physical stress, the consumption of alcoholic beverages, unhealthy foods, and cigarette smoke. 

In much the same way as oxidation causes rust on cars, oxidation inside the body causes a breakdown of cells. If the amount of free radical oxidation in the body is allowed to rise to an unhealthy level, it can result in extensive damage to cellular components and can accelerate the aging process.  

More importantly, it may contribute to a wide range of degenerative illnesses and reduce the body’s ability to deal with other problems, including cardiovascular malfunction, eye disease, and cancer. 

Additionally, it may result in a compromised immune system, leading to immunological disorders and a lessening of the body’s ability to heal wounds and overcome infections. Some studies indicate possible links to arthritis and similar chronic conditions.  

Antioxidants counter these effects by binding with free radicals before they can cause damage. They then convert them into non-damaging biochemical substances, assisting enormously with the reparation of cellular damage.  

Certain antioxidant enzymes are produced within the body. The most well known of these are catalase, superoxide dismutase and glutathione: 

Catalase converts hydrogen peroxide into water and oxygen.  

Superoxide dismutase breaks antioxidants down into hydrogen peroxide. 

Glutathione is a detoxifying agent, changing the form of toxins so that they are easily eliminated by the body.  

This is a lot of science and proof that we need these vitamins and minerals daily for optimum health and wellness. And yes – carbs are where the antioxidants are! Yet another reason to include the “smart” carbs into your daily nutrition.

Other antioxidants can be consumed through the diet. Some of the better known include the antioxidant vitamins beta-carotene, vitamin B6, vitamin C and vitamin E.  

Minerals such as selenium, zinc, glutathione and co-enzyme Q10 may also have antioxidant properties, and so may flavonoids such as cranberry, some amino acids, plus organic extracts from milk thistle and the tree known as ginkgo biloba.  

A diet rich in fresh fruits and vegetables provides a large supply of these antioxidants, to help eliminate damaging free radicals. The highest concentrations are found in fruits and leafy green vegetables, such as carrots, orange and red peppers, spinach and tomatoes.  

Cooking can destroy some antioxidants and interfere with the body’s ability to absorb them, so eating raw vegetables and fruit, and including sprouts in the diet can help. Steaming vegetables as opposed to frying, microwaving or boiling is also a good idea. 

Antioxidants are best taken in combination, since single antioxidants, such as vitamin E, need other vitamins in order to work as an effective antioxidant. Food and natural supplements may therefore provide the most bioavailable source of antioxidants. Natural products from the rainforests of the world are some of the best sources of natural antioxidants ever found. Fruits like the acai berry are amazing in the health world because of the wide range and high number of antioxidants they contain, making them a perfect source of antioxidants. It’s no wonder that the acai berry has been dubbed one of the top 10 “superfoods” in the world.

EAT ALL THE COLORS!

Antioxidants are all the rage today.  And, justifiably so.  Remember, antioxidants help neutralize free radicals which cause cell damage, which ultimately can lead to diseases of the heart and cancer.  It seems everywhere you go it’s blueberry this and blueberry that.  You have your choice of wild blueberry juice, blueberry-pomegranate juice, blueberry-cranberry juice and so on and so on.  

Now, don’t get me wrong.  I love blueberries.  But, in our rush to embrace the latest antioxidant food craze (blueberries, cranberries, pomegranates) we’re ignoring some very high-antioxidant foods that are probably sitting ignored in our cupboards.

“What?”  You ask, “What could possibly be higher in antioxidants than my beloved wild blueberry?”  Well, how about the small red bean?  That’s right, I said “bean.”  The small red bean actually has more antioxidants per serving size than the wild blueberry.  And the red kidney bean and pinto bean have more antioxidants per serving size than a serving of cultivated blueberries.  

What other foods are high in antioxidants?  For starters, there are artichoke hearts, blackberries, prunes, pecans, spinach, kale, russet potatoes and plums.  And, no, that’s not a mistake.  Russet potatoes are on the list of foods high in antioxidants.  

The truth is, there are many common foods high in antioxidants and you should not just restrict yourself to one particular food source.  Why?  Well, have you ever heard the expression, “eat your colors?”  That refers to the fact that foods are in different color “families” containing different types of antioxidants which have different benefits.  For example, the yellow-orange color family of peaches and nectarines help our immune systems.  The purple-red color family of foods (pomegranates, plums, berries) helps reduce inflammation.  It’s important to eat foods from all color groups to reap the full benefits of antioxidants.

The good news is that you can eat healthy foods high in antioxidants (by eating them raw, cooking them, or juicing them yourself) without having to pay a high price for the “flavor of the month” antioxidant juices being peddled in the supermarkets.  

So, give your blueberries some company at the dinner table.  Invite some beans, spinach, potatoes and artichoke hearts and enjoy your antioxidants!
