Java - the good and bad

So I get a newsletter from once a week in my inbox. This morning's edition tells me that a recent study claims that drinking coffee can make you live longer. This is great news to me, but it also listed some caveats... Here is the article:
Healthy or Not, Here I Come!
Over the years, research has produced mixed results on the health benefits of coffee. But a recent study was a win for the earthy brew. Heavy java drinkers (2 or more cups per day) experienced a modest decrease in all-cause mortality, including death from heart disease. We can probably credit the antioxidant-rich beans used to brew the stuff. In fact, Americans drink so much coffee that it’s one of our top sources of antioxidants. Here’s more good news about coffee.

Reality Check
So what are the caveats for coffee drinking? There are only a few. If you are sensitive to caffeine, you don’t need to be told not to be a java junkie. And unfiltered coffee can raise blood fats, so use paper filters and ditch the French press. Although it remains to be seen if coffee has a long-term impact on blood pressure, we know it can cause a temporary spike, so go easy if you have high blood pressure. And -- as always -- do everything in moderation. A pot-a-day habit probably doesn’t do anyone any favors. Check this RealAge article for more benefits of the brew.
Is anyone else bummed about the advice to ditch the French press? I just got mine about 6 months ago and I love it! I no longer have a coffee machine sitting out on my counter (replaced by an espresso machine - mmhmm!) and I like that I can easily tuck it away in a cabinet. So what are blood fats anyway? I wiki'd the term and here is what I got...
Blood lipids (or blood fats) are lipids in the blood, either free or bound to other molecules. They are mostly transported in a protein capsule[citation needed], and the density of the lipids and type of protein determines the fate of the particle and its influence on metabolism. The concentration of blood lipids depends on intake and excretion from the intestine, and uptake and secretion from cells. Blood lipids are mainly fatty acids and cholesterol. Hyperlipidemia is the presence of elevated or abnormal levels of lipids and/or lipoproteins in the blood, and is a major risk factor for cardiovascular disease.
Well crap. Now I'm thinking maybe I should dig out my coffee maker from the donation pile... at least for the times that I'm on a coffee kick (vs. espresso).
