Oxidative Stress and its effect on us

Recently I stumbled upon an interesting topic on Oxidative Stress. I shall copy and paste the information here so you can have a better understanding on the subject matter:

“In the cytoplasm of the 60 trillion cells in your body, there are in each cell hundreds of mitochondria, organelles that take the food you eat and the oxygen you breath and produce the energy your body must have (ATP). Mitochondria have their own DNA distinct from nuclear DNA, and damage to mitochondrial DNA may be a major cause of aging. As oxidative phosphorylation and glycolysis produce ATP, the mitochondria use an electron transport chain. This process is imperfect and results in charged particles, atoms or molecules that have an unpaired electron in the outer ring. These dangerous free radicals include reactive oxygen species, such as hydrogen peroxide, hydroxyl and superoxide, as well as reactive nitrogen species. Because they are charged they are highly reactive and can damage lipids and cell membranes, proteins and enzymes and DNA. The great majority of free radicals are generated in the mitochondria but there are many other processes that can generate them.

To defuse these dangerous free radicals, the body has built in defense mechanisms, including endogenous anti-oxidants superoxide dismutase, catalase and glutathione. In addition our diet is an important source of antioxidants to counter free radicals. There are thousands of antioxidants, and fruits and vegetable are loaded with them (Diet: CRON). Most of the time our endogenous and dietary antioxidants combined can control the free radicals and minimize any damage.”

So it only makes more sense that diet is crucial to ones’ health and skin condition. It is sometimes very difficult to keep up with your goals and have enough discipline to make sure you’re following the most beneficial diet you have created for yourself. While it’s alright to play cheat once in a while, I think it requires much self-discipline and correction overtime to stick with a standard diet that you have created for yourself eventually.

For instance, I dined out at a Chinese restaurant today and I made a mistake of stuffing myself to full. It is an act absolutely discouraged because I have learnt that it is considered toxic to your body if you eat a 100% full meal, or in other words, feeling a 100% full after your meal is not recommended to anyone who wishes to be healthy.

So I have made a mistake, perhaps it is a good thing to have a blog and keep myself reminded of the process and mistakes I will or shall make throughout the period.
