Protective effects of antioxidants
There is growing evidence to support that fact that a diet rich in antioxidants may reduce our risk of chronic disease, and perhaps even cancer. While the data on antioxidants is striking, there is much contraversy as to how we translate this evidence into clinical practice. To gain a better understanding of how antioxidants protect our DNA, we must travel back to Biology 101 to revisit a few basic concepts on cellular function. So bear with me. I promise this will all come together at the end!
What is DNA?
If you are a CSI fan you know that DNA evidence collected at the scene of the crime is used to help identify the bad guys. With the exception of identical twins, each of us have a unique DNA code. DNA (deoxyribose nucleic acid) carries the fundamental building blocks for each person’s genetic makeup and is a component of virtually every cell in the human body. DNA must replicate itself exactly every time a cell divides. Enzymes play a critical role in maintaining the integrity of the chromosomes on the DNA to ensure that the genetic code remains the same every time the cell replicated
Most of us have the false impression that our DNA is fixed, meaning that you are “stuck” with the genes that your ancestors passed down to you. What you may not realize is that genes can be altered, mutated and switched on or off by a variety of factors including; lifestyle choices, free radical oxidation, chemicals and environmental toxins. Similarly, your risk of developing a familial disease can be significantly reduced by creating a healthy internal environment by giving your body the proper vitamins, nutrients and minerals.
