Artificial antioxidants; an artificial 'safety net'

The goliaths of the health food industry are awfully adept at exploiting buzz words and trendy ingredients to make their product seem superior to the competition and antioxidants top the charts. Their rise to power and ubiquitous presence is a product of mastering the various challenges associated with processing, packaging and marketing food; not necessarily because they result in a product that is truly healthful. In interest of shelf life, cost per unit, mouth feel, and taste, many of the natural nutrients found in a food’s primary ingredients are stripped away and lost during production.

 

Enter the world of fortification. By replacing lost nutrients with artificial modifiers such as antioxidants and fiber, food producers can have their cake and eat it too. Furthermore, supplement companies are quick to point out that the American diet is devoid of many important antioxidants that are necessary additives. The problem with this approach is that antioxidants are needed in a proper balance to perform properly. Moreover, numerous clinical studies have shown that artificial variants of these essential nutrients do not function in the same way as their natural counterparts.

 

Let’s look at a downright free-radical-eradicator like vitamin E. Studies have repeatedly demonstrated that when consumed in high quantities through whole foods, vitamin E greatly improves overall coronary function and decreases the risk of having a heart attack. However, a study published in the American Journal of Clinical Nutrition (Liu et al., 2003) found a huge disparity between natural and artificial vitamin E. The study found absolutely no improvement with the same levels of supplemental vitamin E on heart and artery function. A large meta-analysis performed by Miller et al. (2004) at John Hopkins University concluded that supplemental vitamin E may lead to an increase in all-cause mortality. These are just two studies of many that have shown either the negligible or harmful effects of artificial antioxidants.

 

Now let’s take a step back and look at the impact of these studies. The American Heart Association released an official statement after the review of several studies concluding that “using dietary supplements of antioxidants to prevent cardiovascular disease should not be recommended.” The US National Cancer Institute has looked very closely at the effects of artificial antioxidant supplements and issued statements recommending against their usage advising that they be consumed through fruits and vegetables instead.

 

The largest examination of supplemental antioxidant studies to date was performed at the Copenhagen University Hospital in Denmark where they looked at studies involving over 200,000 participants. Their conclusions were that both artificial vitamin A and E do not provide health benifits.

 

These findings have been hotly debated with strong opinions on both sides of the argument. My stance has always been to get your antioxidants from natural sources such as fruits and vegetables. In addition to containing large amounts of antioxidants they are filled with fiber, polyphenols and other phytonutrients that work in perfect harmony with your body. Besides, I have yet to read a study that highlights the possible dangers of antioxidants in organic produce.
