I see that I've been remiss in adding to this description of the great plague of 2020. Let me try and catch up with what is happening and what the future in the short term might hold.
The data are still unclear as to what is really going on. Was the lock down a good thing? Hard to say and how would you measure it? The official numbers in re the viral deaths are hopelessly jumbled. So the concept of All Cause Mortality is the one number that is probably useful.
I was not familiar with the ACM until lately. Oh, Barb has bandied it about a few times but it didn't really register with me as to its usefulness. Then I got into some of the science being done around low carb diets and sodium intake and other factors. Then the proverbial light went on. In the area of epidemiology you can seek to assign weight to a variable by looking at ACM. You group your data and then screen for something. For example you look at sodium intake. You hopefully are able to measure the actual amount of sodium ingested for a group, then subdivide the group by intake amount and over time you see who lives the longest.
There are problems with a lot of this kind of thing. For example did you measure the actual intake, are the subgroups similar enough to draw conclusions, an issue might be that in one group they all smoked and in another alcohol consumption was very high or low of just different? If you can't control these other things then you can't in good faith conclude that the mortality is due to sodium intake.
What you see with these studies is a U shaped curve with mortality on the Y axis and intake of sodium on X axis. Your mortality is high if you have not enough sodium and lower if you have the proper amount and tending to climb as you have too much. The bottom of a U curve can drop below the 1.0 line, which is the probability of death being "average." If it drops below 1.0 then you could conclude that a certain amount of the sodium would be protective of life.
Sodium is an interesting one and I didn't choose it randomly. We've been told about the horrors of salt for a long time by our health betters. They still sell low sodium this and that at the grocery. I understand that excess sodium intake will cause blood pressure to rise a bit and if that's a problem, then low sodium stuff may be useful and important. But the ACM curve for sodium is quite interesting. If you get none, you die. Sodium is used for a lot of basic bodily functions and without it, it's certain death. So the low sodium intake area of the ACM curve is quite steep. The it lowers quite dramatically as the intake approaches 4.0 grams per day. Note that this is still more than the recommended daily amount which I think is about 2.5 grams per day. Now you might wonder how steeply the curve rises as sodium intake increases. If you eat 4.5 are you much worse off? How about 7.0 -- three times the recommended amount? The actual curve, estimated, is a very small rise as the intake increases. Basically as long as you get to 4.0, any excess is not a big problem, certainly less than not eating enough.
I just looked at a video where a doctor mentioned that there was a doctor doing research in the 60s and 70s, gave rats about 100 times the amount a person might eat, found out blood pressure was up and published.
Sadly, the federal government was looking to help folks out about this time and Sen. McGovern, see previous posts, thought the rat data was directly of value when applied to humans. So that's where the US recommended amount came from. It seems to be complete crap at this point, but this stuff changes slowly if at all.
If you are eating very few carbs then this is important to you as a lack of insulin will cause the body to dump salt. One of the reasons that starting a keto diet will cause rapid weight loss is this, the salt goes and then excess water goes too. This is not always a good thing as you still need the sodium and when on Keto, you are encouraged to be busy with the salt shaker.
I seem to have gone well off the rails here. But we were talking about Covid data and it does apply somewhat. The news is full of officials who are classifying any death with Covid as a death caused by Covid. Rampant rumor abound as to federal payments for Covid health issues, etc. It seems there is financial motivation to do that. Ok, fine, I understand monetizing death, but it does make it more difficult to craft future public policy if the data are polluted. But the ACM will really determine if the virus caused a lot of excess deaths or not. I did see a graph for Sweden which showed about 47,000 deaths as of June 5. The average deaths for Sweden in a year about about 90,000. It looks like they are above the curve a bit. I suspect that more deaths occur in winter than summer, so there may be excess deaths there. Sweden did not lock down to the extent of other countries. It might have been a better response, but it is easily apples and oranges - Stockholm is not New York, for example. But certainly there are not three times the deaths in Sweden than in a usual year.
This is getting long and I'm not sure I have a point to make, but the above stuff has been running through my head while sitting the recliner and wishing for more general access to the world. Pickleball is back on! Yeah! And I've been getting lots of golf in. My life is back to normal for the most part. We are still cooking a lot. The grocery bill is huge, but the restaurant bill is tiny. The food is better, but we have more kitchen duties. We have worked out a routine, so the cooking and cleanup is not a big deal. The dishwasher is getting a workout, however.
