Is there research supporting nutritional benefits of antioxidants?
This morning I emailed Vishal:
Is there research supporting nutritional benefits of antioxidants? People hype this as a reason for eating dark chocolate and drinking tea. What are your thoughts?
He responded:
Tons of evidence supporting various antioxidants - both water soluble (i.e. vitamin C) and fat soluble (i.e. vitamin E). The wikipedia articles are informative.
In general though, when clinical trials are done with high doses of antioxidants, there are mixed results: sometimes they seem beneficial, sometimes they seem harmful. And then there are studies done with an antioxidant and another drug in combination (like polyunsaturated fatty acids and coenzyme Q10).
We know that all the most nutritious foods have lots of antioxidants. To see a clinical trial with unfavorable results indicates (to me) that we are missing something, that an antioxidant is not as powerful - and, in certain situations, even harmful - when taken out of the chemical milieu of the plant/animal/food, or when consumed out of proportion to what we “normally” consume. By “normally,” I’m thinking of the way people have lived for the past several thousand years.
(The “harmful” study that comes to mind was one that found a greater risk of a heart attack for people with heart disease taking high dose vitamin E.)
Also, an antioxidant is one class of molecule, and we have unearthed only a handful of them. Some of these “beneficial molecules” we call vitamins, some of these we package as supplements (i.e. Resveratrol <—- you should read about this one). Healthy food is not healthy because, for example, it has alot of antioxidants. Healthy food is healthy because we have found it to promote health, and they happen to have alot of antioxidants….. but there are millions of other molecules that also contribute to the healthful effects of food. We just haven’t studied or discovered them yet.
A link Shal’s recommended reading:
Facebook is killing it with the new design, IMO. The wall / public message is my favorite example where we see individuals advertising themselves.
Myspace comments where bands promoted themselves on other bands’ pages were more blatant, but the new Facebook wall is more interesting than Myspace comments in two ways.
1. On Facebook, rather than promoting my band, I promote myself and my relationship to you, which is more subtle. For example, I may choose to wish you happy birthday publicly via Wall Post rather than via private message. Why? Because I get no social credit for a private message, but I get my face on your real estate when I post on your Wall.
2. Myspace comments are cordoned off into their own section. With the new Facebook redesign, my posts on your wall are mixed into your feed of personal actions, giving my posts on your realestate equal value with the content you publish. This real estate is much, much more valuable than a separate coments section which can be visually turned off like an ad banner.
What other examples of social gestures / personal advertising are interesting? Perhaps tumblr, where I reblog your content into my space—sort of an opposite approach. If you have other examples or thoughts, leave them in the comments.
The new commercial during the Olympics inspired me to go back and find the original Marvin Gaye clip. I remember watching this on TV in 1983. What an incredible year for music.
Thanks again, Mint! This table is really useful and something I’ve actually been looking for. Brilliant company.
I don’t know when this happened, but mint.com now has the ability to export transactions. 2008 taxes will be cake!

Cannot wait to see CC & Jason’s presentation. The slides are looking awesome!
“ I’m not the first person to come up with this idea, far from it. The idea that specific types of carbohydrate foods, rather than carbohydrate in general, are responsible for the diseases of civilization, has been around for at least a century. It was an inescapable conclusion in the time of Weston Price, when anthropologists and field physicians could observe the transitions of native people to Western diets all over the world. This information has gradually faded from our collective consciousness as native cultures have become increasingly rare. The Kitava study is a helpful modern-day reminder.
