Oxidation is something that most of us see in life — when we leave some iron out and it rusts – that is oxidation. There is a theory that the stress of oxidation leads to many diseases including heart disease, cancer, and even aging. As a result, there has been a rush of studies examining the role of anti-oxidants and to see if diets rich in anti-oxidants will show a decrease in those disease.
But before we rush to buy the latest anti-oxidant capsule, berry, fish, or whatever – think about some of the things that are positive about oxidants. Ok – yes, you need the oxidants to wash your clothes. Nothing like some oxy-clean to whiten the stains. But, the body uses oxidation in a variety of ways that are useful.
When a bacteria is encountered by white blood cells (poly morphonuclear leukocytes) they use oxidation to destroy the microbe. When the body encounters a cell that isn’t behaving quite right – oxidation is used to get rid of it.
The gray hair so many color– it is gray because of the “bleaching” effect of anti-oxidants. Ok- maybe that isn’t a great example, but it does provide protection for the scalp – in spite of whatever toxic materials people put on their head to make it pretty.
Then there is the matter of ingesting the anti-oxidant. Did you ever wonder how long it takes the stomach to inactivate it? About a nano-second. So you are eating something you think is good for you – -and in a nano-second is inactivated by your wonderful stomach trying to protect you from doing yourself harm.
We have a balance in our bodies– those things that can help us- oxidation against bacteria and cancer – -can harm us if it runs wild. Just like our immune system can turn against us.
So before you buy the Pom-Wow, drink it because you like it – not because it might help you.
You want your body to oxidize some things (my hair, now the true platinum color) – you want to kill invading bacteria, cells that go wild (unlike the teenage daughter who wants to go to Mexico for spring break – although oxidizing the boys in Mexico might be a good thing).
Want to learn more nerdy stuff about anti-oxidants– well, I could do that, but it is Saturday morning and I am a bit tired. Suffice to say – here are a few simple facts:
(a) oxidation is a part of the cycle of life and if we don’t have it basic chemical process that keep us alive will not work
(b) oxidation is good for your bodies protection
(c) people who sell you this fad stuff are usually in some pyramid scheme, or not giving you all the facts
(d) most of the anti-oxidants you ingest will not survive past your stomach and if they could you may change the balance of your body in a way that you would not intend
(e) all of the studies done so far show that the addition of anti-oxidants do not have a beneficial effect for your heart, to prevent cancer, or to increase lifespan.
So, if you like Pom-wow – drink it. But don’t think you really need it otherwise. I like Pom-Wow, but I also like red wine. I wonder if the cops will stop me for driving under the influence of anti-oxidants?
