Omega 3

Someone threw a bottle of Omega-3's at me. 
Don't worry, they were just super-fish-oil injuries.

I had to do a correction a few months back saying that recent data shows that Omega 3 supplements really aren't helpful in preventing heart disease and more information I saw recently relates to that.

There was a good article in the Guardian about the environmental toll the Omega-3 supplement industry takes on the world.  I was surprised but not too surprised to learn that they started harvesting krill instead of anchovies for their oil just because it doesn't make people's breath smell as bad.  Not a great reason to decimate an ecosystem, especially if there's not a good reason to do it.

The main diets shown to go along with heart health are the Mediterranean and Nordic diets, which both stress fruits, vegetables, beans and legumes, whole grains, and fatty fish.  That's kinda where we got the idea the Omega-3's were the secret to heart health but the idea that we can figure out one part of something complex that is supposed to be good for our health continues to be disproven.

Resveratrol in red wine was supposed to be good for us, but it's more complicated than that.

For a while, everyone was taking Vitamin E - now it's not generally advised.

All women going through menopause used to be on hormone replacement therapy, but then we found out things were a little more complicated than that

I think at this point, there is very little reason that anyone should be taking omega-3 supplements.  Eating fatty fish a few times a week, sure.  And also focusing on the other tenets of those diets, mainly eating more fruits, vegetables, and beans/legumes to maintain your body like the well-fish-oiled machine it is.

NSAIDs

Advil and Motrin are ibuprofen, then you have Aleve (naproxen).  Those are the over-the-counter ones.  Prescriptions are Mobic (meloxicam), nabumetone, indomethacin, Toradol (ketorolac), diclofenac, Lodine, and the list goes on.  All of these medications are in a class called non-steroidal anti-inflammatory drugs (NSAIDs). I'm giving you this list because there is mounting evidence that these medications a) don't work as well as we'd thought and b) have some very serious long term side effects we're finding out more about. NSAID's act by reducing the amount of prostaglandins you make in order to reduce inflammation.  However, prostaglandins have a ton of other effects and are involved in the maintenance of just about AIDs and also stronger if they are taken every day and/or around-the-clock.  every other organ system that you have.  The effect is stronger with higher doses of NS NSAID's work best and are best indicated for times when something is r...

Kidney Stones

I've written about this previously , but it's often hard to explain to people what a 10 is on the "1-10" pain scale if they haven't been in that spot before.  For women who have had children, they generally know what a 10 is, but for men it's a little harder.  When I was a medical student on my psychiatry rotation, we had a patient calmly sitting there saying his pain level was at a 10 and our resident, who was an ex-military sniper with a large skull tattoo on his forearm and a crosshair through the eye, calmly leaned forward and asked, "so if I lit you on fire and ran you over with my truck, you could not be in more pain than you are now, correct?"  The patient changed his answer. Getting to the point, a kidney stone is about the close I can come to describing a 10/10 pain to people who haven't gone through childbirth.  The fundamental issue is similar - your body is trying to move a big solid thing through an opening that was not really desig...

Pain

Sorry to be a pain I would say about 90% of the comments I hear from people about their pain threshold is that they think they have a high pain tolerance.  Which is statistically impossible unless I just attract people who have a high pain tolerance. We traditionally ask people to rate their pain on a 1-10/10 scale and while we hear a lot of 9's and 10's, I would say that, having been present for a number of them, a 10/10 would be giving birth to a first child.  For those who haven't experienced that, my old psychiatry resident described it as "so if I lit you on fire and ran you over with my truck, you would not be in any more pain than you are now" (he was also a former Marine sniper which might explain that). But this is pretty pervasive throughout the medical system and got me wondering as to how people's understanding of what their pain threshold was matched up to what it really was.  Fortunately, there were researchers who had a yen to poke peopl...
