Red Wine Can Prevent Stroke (in Mice)

According to Reuters, scientists from Johns Hopkins University fed mice resveratrol (a compound found in red grape skins and seeds) before inducing stroke-like damage. Animals suffered less brain damage than similarly damaged mice who were not treated with resveratrol.

Red wine contains approximately 5 mg/L of resveratrol, whilst white wine has much less - the reason being that red wine is fermented with the skins, allowing the wine to absorb the resveratrol, whereas white wine is fermented after the skin has been removed (source: Wikipedia)

It has not been sufficiently proven that red wine has a protective effect against stroke in humans but this does not stop people from buying resveratrol capsules on the Internet.

According to researchers, you have to drink about 2 glasses of wine in order to consume the "required" amount of resveratrol. Currently, the content of the food supplements is not FDA-regulated, which means that those resveratrol capsules you bought on the web for $ 30 may not contain resveratrol at all.

Doubt on Anti-Aging Molecule as Resveratrol Trial Is Halted


  1. For teetotalers, I wonder if plain old red grapes are a good substitute...

  2. A glass of wine every night. It's all good.

  3. assuming a glass is about 200 ml, two glasses will just be equiv to 2 mg resveratrol. that's 10x more than those supplements claim to have!

    brad, according to this article from linus pauling insitute, red grapes are supposedly ok, as are boiled peanuts.

  4. Awesome post! Have you had a chance to watch 60 Minutes, Fox News, Oprah or Barbra Walters segments last weekend about it?

    Basically, it shows promise in mice. For mice, has shown major health improvements including blood sugar control. Keep in mind that 6 out of 10 major drug successes in mice - fail in humans. But the limited human trials showed promise and there are some patients that claim it helps. However, this could be the 'placebo effect,' and only empirical data under controlled experiments can tell for sure. It will take a few years for these clinical trials to conclude.

    You can get supplements of the extract right now. While it is safe, it is not guaranteed to work. Before making a decision, you should watch all the videos. Here's the a recap from all the trustworthy shows:

    I did some research and learned the following: You can only get 1-2mgs of it in a single bottle of wine. So, white, it's a good excuse to drink wine, but you really won't get much benefit. There are resveratrol supplements on the market - but many do not have the required strength and they don't work for everyone. The only way to know for sure is to try the supplements. Hope you find this interesting... its a future hope for the fountain of youth and treatments (not cures) for countless diseases.
