Free Radicals and Antioxydants!

I was going to make a long, thought out post about this but it pretty much cover it. Just so you know, when it attacks fats, you need those. (I am going to assume that everyone here has taken 7th grade science) Your cell membrane (plasma membrane) is made of fats - so no fats = death. That is why they are called "essential fats".

Moreover, this is the leading cause of cancer and aging, and worse there is no way to prevent it - just "treat" it.

As far as controvercy goes, this just like aliens. Everyone wants all the scientists to be wrong, but they are not - THERE IS NO (good)DEBATE IN THE SCIENTIFIC FIELD AS TO THE EXISTENCE AND FUNCTION OF FREE RADICALS!

Unfortionatly, this article does not go into great detail, so if any further questions arise I will answer them to the best of my ability.

Skimmed through, didn't really see what was new about any of this. Everyone knows free radicals exist as far as I know. Is there really some debate about this, as even the most nutrition-retarded people I've talked to have heard of them. Or am I missing the point?

[Origional]

There are two reasons for this post:

1) to make those not aware of it aware

2) to provide techniques for treatment

Your post fails so hard. I'm not even going to bother reading what you linked, but I can tell you a few things about your seventh grade science "facts".

i) Your cell membrane is composed of phospholipids (fatty tails! ZOMG), cholesterol, and a SHITLOAD of protein. About as much protein as phospholipids and cholesterol, actually! Who'da thunk it? Cholesterol is a component of "fat" to most people, so I suppose you could be right if you went by that definition. Fat is used by the body for joint support, insulation, storage of vitamins, minerals, energy and a shit load of other things.

Certain fats are called ESSENTIAL because your body can't make them. Ever heard of alpha linoleic acid or arachidonic acid? Your body needs them, and you can't make them.

Anyway, free radicals? They exist. The ones that are responsible for mtDNA (mitochondrial) and nuclear DNA damage are generated from the very oxygen we breathe (google ROS or reactive oxygen species if you don't know what I'm talking about). Not to mention when our body starts tossing its chemicals at the shit we ingest today. Take home point: free radicals exist. Get over it.

free radicals are bad

eat fruit/vegs/honey to reduce them

This article : tl;dr

Next time please read my full post before responding (I am thanking you in advance and will not answer if you don't).

Quite simply, there purpose of this post is to (1) educate the people that have not heard of it. This is just on a basic level, as I posted earlier I would be willing to go into more detail. I know that quite a lot of people out there have not heard of it. This post was meant to fill that basic information gap.

(2) This was meant to explain antioxidants. I know many people have heard of them - but, again I feel that there is a lack of true knowledge on the subject.

(3) To provide a means of means of treating free radicals through the use of antioxidants.

RIGHT NOW I AM GOING TO SAY THIS: THOSE WERE THE ONLY REASONS FOR CREATIONS OF THIS THREAD.

Now, the added footnotes (the only thing that you evidently read) were my own ideas made to supplement theoriginal article. Thus, one can concur that your comments are not directly related to the original article.

Just as a thought, how can good intentioned advice with sound information be a fail?

Alpha linolenic acid, not alpha linoleic acid which does not exist, is merely a plant form of eicosapentaenoic acid, the actual fatty acid required by the body.

The few people who haven't heard of free radicals would be better off educated on other matters more, such as why they shouldn't shove donuts down their throats. Only people who are completely retarded in regard to nutrition haven't heard of free radicals, and free radicals are the least of their worries.

I read your post only, Origional. Not the shitty article that came with it.

Alpha linolenic acid, not alpha linoleic acid which does not exist, is merely a plant form of eicosapentaenoic acid, the actual fatty acid required by the body.

Alpha linoleic acid doesn't exist? It does, and is a part of membrane structure, just as alpha linolenic acid is as well. As for EPA, oh gods I don't think either of us want to get into a huge EFA discussion xD. Well, I certainly don't haha so touché good sir.

Sorry to disappoint.

They're not called essential fats because cellular membranes are made of fats. That is what they're made of, but EFAs are called that because it is essential to get them directly in the diet because they cannot be synthesized from other fats. They are the lowest fats which all other fats can be created from, or something like that. How much we actually need any of them specifically, is not totally known.

Cellular membranes can be composed of non-essential fatty acids too. Including saturated fats. Actually, if you have too many EFAs (polyunsaturates) in your membranes, it needs cholesterol to help stabilize the membrane or it will be too loose, cholesterol is the condom that EFA-based membrane sluts need. Never mind I just noticed someone else already wrote that...

But anyway, free radicals don't usually float around in your body for too long. They react, they damage you, and it might cause a free radical chain reaction or something as it goes through a chain of molecules slowly stabilizing or something.

Antioxidants don't so much fix the problem as if you have them there ahead of time, free radicals damage them instead of damaging your living tissue. It's better for a toxin to kill a vitamin E molecule than it is to kill your cell membrane or start creating plaque in your brain or arteries t cause Alzheimer's or atherosclerosis.

yaya

I did not post this so that the enlightened would tear it apart. I posted it so that the majority of TT members who do not know about it would.

I see... well... too bad...
Preventing oxidation may have earned antioxidants their name, but we now know these substances do more than disable free radicals. Antioxidants also help reduce inflammation, keep arteries flexible, and preserve the genetic material every cell contains to prevent mutation.

This is from the article. It's a stupid statement. Disabling free radicals is all an antioxidant does (in its role as an antioxidant).

Free radicals occur in inflammation, free radicals damage genetic material, and free radicals can degrade arterial lining reducing its flexibility.

So, all those 'extra benefits' they brag about are merely a side effect of reducing free radicals. That's the whole fucking point.

Now, some free radicals also serve roles as vitamins or something, like how many vitamins are also antioxidants, so they may have mentioned that...
