Sometimes I (almost) envy mice, rats, and yeast - it seems that almost any aging research we carry out on them doubles their lifespan and returns semi-senescent (say, a human equivalent of about 60 years of age - not thinking of anyone in particular, of course) to youthful vigor. It now appears that dramatic anti-aging results are associated with dietary ingestion of buckyballs, more properly known as C-60 fullerene.

A recent French study looking for chronic toxicity resulting from ingesting buckyballs dissolved in olive oil found that 10 month old rats who ingested the human equivalent of a tenth of a gram of C-60 buckyballs (which in technical grades cost less than US$10/gram) several times a week showed extended lifespans instead of toxic effects.

All C-60-treated rats survived to at least 59 months, with the oldest surviving to 66 months. The control group lived for periods ranging from 17 months to 37 months, while an additional group fed only the extra olive oil lived for periods of 36 to 57 months. For the curious, the olive oil dosage was equivalent to a person adding about eight tablespoons of uncooked olive oil to their daily diet without compensating for the additional calories. Similar results have been reported for mammals held in a state of semi-starvation, but that is obviously not a pleasant lifestyle.

All fullerenes are susceptible to clumping when dissolved in oil, so the preparation of the olive-oil/C-60 solution is rather lengthy. In these tests, 50 mg of C-60 buckyballs were added to 10 ml of virgin olive oil. These were stirred for two weeks at ambient temperatures with no incident light. Following the stirring, the solutions were centrifuged at 5,000 g for an hour. The fluid was separated from the precipitate, and was then passed through a 0.25 micron filter. The resulting liquid contained 0.8 mg/ml of C-60 buckyballs.

The results beg the question - what is going on here? Is the life extension just for those lucky rats again, or is there a mechanism that might transfer over to humans? The study was aimed at discovering if a diet of buckyballs has any toxic effects, and the good news is that no toxicity was found. The buckyballs did move throughout the body (including the brain and central nervous system), and even enter individual cells. The ingested C-60 had an elimination half-life from blood of about 10 hours, so was essentially fully eliminated from the body within two days. It is not clear from the report if the C-60 was eliminated from intracellular fluid on that time scale.

Specific studies of the effect of C-60 buckyballs on oxidative stress in the rats were performed by studying the effects of carbon tetrachloride (CCl4) injection. Carbon tetrachloride is well known to be poisonous to rats, being highly hepatotoxic (toxic to the liver). It is also associated with delirium and intoxication such as is experienced in the abuse of solvents.

Rats which had been pretreated by water, by olive oil, and by olive oil containing C-60 buckyballs all showed typical signs of intoxication within a few minutes of CCl4 injection. However, while intoxication persisted in the water and olive oil groups for 24 hours, the olive oil and C-60 group emerged from intoxication after only five hours.

In rats experiencing the pretreatment, but unexposed to carbon tetrachloride, autopsy revealed essentially normal livers. In those given a CCl4 injection, however, the livers from rats pretreated with water or olive oil showed important damage - a great deal of inflammation as well as large necrotic areas (dying or dead tissue). In contrast, the livers from rats pretreated with olive oil and C-60 buckyballs showed little damage or CCl4-induced cell death. Biochemical markers of liver damage showed far less elevation in the rats pretreated with olive oil and C-60.

It does appear there is a real physiological effect on metabolic processes, and that oxidative stress in particular is significantly reduced in rats by chronic oral ingestion of an olive oil/C-60 solution. As oxidative stress is one of the factors usually associated with aging, there may well be a reasonable mechanism for the lifespan extension, especially if excess oxidation within individual cells is prevented by intracellular buckyballs. Will people react to a treatment of this sort with lifespans of 180-200 years? Only time will tell.

The research was recently published in the journal Biomaterials

Much more in depth article than the one I previously read. Wonder where I can get ahold of C-60 buckyballs...

Seems like the mice fed only on olive oil, did quite well; while those having added buckyballs, survived only a couple of weeks more. Is this an add for health giving properties of olive oil? Perhaps I should buy some shares!

Toys"r"us in their secret military biochemicals section between the lego and hotwheels ;D rats sometimes react to things that dont work in humans and many strange things make rats live longer like a stress study i read about that mice who were shouted at daily for ten minutes had shorter lifespans and the ones who were given 10min of classical music lived much longer than the control group. Maybe shouting/music does have a real world human effect. So il take you to toys"r"us and il check on you every decade. What i want to see is human cell culture tests or was their goal to extend rat lives?

^ Their goal as stated above was to try and determine any toxicity effects. They weren't expecting the life extension as far as I understand.

re: "The ingested C-60 had an elimination half-life from blood of about 10 hours, so was essentially fully eliminated from the body within two days. It is not clear from the report if the C-60 was eliminated from intracellular fluid on that time scale." This is an absurd conclusion, unsupported by any of this 'quasi'-experimental presentation. Such trash-science has no place other than in the Journal of Ludicrous Conclusions. J.A., M.D.

tkj: this is not a scientific publication. Gizmag is targeted at the general public. The message is: "the elimination half life from blood plasma is short, so if it diffused freely inside the body, it would be greatly reduced in 2 days, but we don't now if it stays inside the cells". And as I see it, the message is clear. For a more thorough interpretation your quouted paragraph, change "body" for "plasma". For criticizing the conclusions, please read the paper.

"This is an absurd conclusion, unsupported by any of this 'quasi'-experimental presentation. Such trash-science has no place other than in the Journal of Ludicrous Conclusions. J.A., M.D. " Gizmag.com rewrites to make it easier to read for the laymen ( J.A., M.D.'s out there) , it’s not meant to be your new medical journal. Read past a gizmag.com article (editing) and get to the original source.

@Thunderbird4 - The exact quote was... "Similar results have been reported for mammals held in a state of semi-starvation." It has been well established that a longterm severely calorie-restricted diet in humans results in cells entering a protective state that extends human life for a decade or two. Olive oil consumption has been noted to have many beneficial effects but not nearly as dramatic as the life-extending effects of a semi-starvation diet. Therefore, consuming larger than average amounts of olive oil is probably good for you but will not give you the results close to what this article is presenting for the buckyball+olive oil mixture for rats. This article didn't reveal it, but I suspect the rats were probably on a semi-starvation/buckyball+olive oil diet.

All of which begs the question: do humans need to live longer?

Interesting. Buckyballs are also a byproduct of a smoky acetylene torch. I wonder if welders who use acetylene rigs would breathe them in, and would that lengthen their lives? But that effect of olive oil really needs to be broadcast everywhere!
