Once again, science is wrong



Don't eat butter, wait it is OK to eat butter.

Don't eat salt, wait it is OK to eat butter.

Now, don't drink coffee, wait it is OK to drink coffee.

From MSN:
Your regular cup of joe in the morning might provide an extra jolt to your day, but it luckily won’t do the same to your heart, according to new research published Tuesday in the Journal of the American Heart Association.
The University of California, San Francisco (UCSF) researchers pored through data taken from theCardiovascular Health Study (CHS), one of the largest nationally funded observational studies of risk factors for cardiovascular disease in adults 65 years or older. Randomly selecting 1,388 participants (out of around 6,000 in total), the researchers then attempted to find the relationship, if any, between their regular consumption of caffeinated products such as coffee and the likelihood they experienced either premature atrial contractions (PACs) and premature ventricular contractions (PVCs), ultimately concluding none existed.
Though PACs and PVCs, commonly known as early or extra heartbeats, happen fairly often for no apparent reason and are generally harmless, there is recent evidence showing persistent extra heartbeats can be an indication of worsening circulation woes in the heartand brain. On the flip side, according to the authors, the perception that caffeine consumption can cause an increase of PACs and PVCs was based mostly on old studies that didn’t directly examine that relationship. It’s a perception that’s led organizations as venerated as the American Heart Association to precautiously warn against caffeine for people with a history of extra heartbeats.
We blow billions of dollars on these studies about what "causes" heart disease and cancer, instead of trying to cure them.

  2. To quote the late Paul Harvey: "Coffee is good for you; coffee is bad for you. Take your pick."

  3. I drink too much coffee and have to make up for the loss of salt in the diuresis by eating extra salt.
    I learned from an old patient a while back a cure for leg cramps. Put a pinch of salt under your tongue.
    Used to have a lot of problems with cramps. Rarely do now.

  4. Also, eggs -- that is all of the egg and not just the whites -- are now kind of/sort of OK.

    I haven't had the nerve to eat eggs on a regular basis ever since that news came out, but I am now allowing myself two hard boiled eggs per day once or twice a week.

  5. Well, one does have to know and understand the cause of an illness before one can cure it.

    Funny thing is that if you follow the link to the MSN article and its links to source articles, you cannot tell whether any of the 1400 participants in the clinical survey exhibited a single instance of arrhythmia, in which case the study is little more than a medical student's report on the coffee drinking habits of heart healthy people. It is stated explicitly that people who showed any evidence for heart arrhythmia were excluded from the study sample from the start, so it perhaps comes as no surprise the investigation produced a null result, i.e., it found no correlation between the consumption of caffeine and heart arrhythmia. However, even if the study demonstrates caffeine does not CAUSE arrhythmia, the question remains whether it might make it worse for people who regularly exhibit signs of arrythmia and would be advised to limit the amount of coffee they drink each day.

  7. Perhaps the problem is that a food that affects one person over time will not affect another person the same way? Perhaps by the time we figure out what is incrementally bad for YOU it is too late to do anything about it?

    Can't be that; we have all of these researchers that need to have something to do.
