I'm going to live forever

Oh yes, yes I am:

Larger quantities of coffee seem to be especially helpful in diabetes prevention. In a report that combined statistical data from many studies, researchers found that people who drank four to six cups of coffee a day had a 28 percent reduced risk compared with people who drank two or fewer. Those who drank more than six had a 35 percent risk reduction.

Some studies show that cardiovascular risk also decreases with coffee consumption. Using data on more than 27,000 women ages 55 to 69 in the Iowa Women’s Health Study who were followed for 15 years, Norwegian researchers found that women who drank one to three cups a day reduced their risk of cardiovascular disease by 24 percent compared with those drinking no coffee at all.

But as the quantity increased, the benefit decreased. At more than six cups a day, the risk was not significantly reduced. Still, after controlling for age, smoking and alcohol consumption, women who drank one to five cups a day — caffeinated or decaffeinated — reduced their risk of death from all causes during the study by 15 to 19 percent compared with those who drank none.

The findings, which appeared in May in The American Journal of Clinical Nutrition, suggest that antioxidants in coffee may dampen inflammation, reducing the risk of disorders related to it, like cardiovascular disease. Several compounds in coffee may contribute to its antioxidant capacity, including phenols, volatile aroma compounds and oxazoles that are efficiently absorbed.

In another analysis, published in July in the same journal, researchers found that a typical serving of coffee contains more antioxidants than typical servings of grape juice, blueberries, raspberries and oranges.

“We were surprised to learn that coffee quantitatively is the major contributor of antioxidants in the diet both in Norway and in the U.S.A.,” said Rune Blomhoff, the senior author of both studies and a professor of nutrition at the University of Oslo.

These same anti-inflammatory properties may explain why coffee appears to decrease the risk of alcohol-related cirrhosis and liver cancer. This effect was first observed in 1992. Recent studies,published in June in The Archives of Internal Medicine, confirmed the finding.

HT to Feministe.

OTOH, the correlations between increased caffeine consumption and increased rates of depression are fascinating. I keep hoping somebody will have the courage to do some science around that one, but I have so far been disappointed.

What level of consumption do you have to get to for the depression to kick in? This could explain a lot about academics. :P

Seriously though, I have long limited myself to one cup a day with two exceptions: Sunday, when I have 2-2 1/2 cups (the size of my French press) and I allow myself an extra cup during the break of my 3 hour grad seminar (one semester per year).

The reason is, once time I stopped off to go beach camping in Mexico on my way back from Brazil. I thought I was going to die, and that I had dengue fever or something until a friend diagnosed me with caffeine withdrawal. It was miserable. In Brazil I had been drinking like 10 espressos a day. With lots of sugar. And in Mexico, we were doing the "pay some guy a buck to hang our hammocks between two trees" thing, and only had water to drink. Really, aside from the time I got the Yellow Fever vaccine when I already had the flu, it may have been the most painful whole body experience I've ever had (worse than have pieces ground out of my wrist).
