Life expectancy rise in rich countries slows down: took 30 years to prove

> The decline in the United States is driven by increasing numbers of deaths because of conditions such as diabetes and heart disease in people aged roughly 40 to 60.

People are asking if we should be surprised by the headline but are missing this. As suggested in the article by the researchers, there is something dragging down the average since the 2010s. Not even hitting the general expectation of ~75 years. We don’t have solid answers yet, only theories.

So yes, generally while going up against the process of aging is going to create barriers (eg can we get to 130 years old), we are also failing to raise the baseline which is the bigger issue that people might not grasp when it comes to “life expectancy rates”.

> We don’t have solid answers yet, only theories.

The exact quote you gave had a pretty solid answer, certainly not just "theories".

That's not what I meant. A solid answer as to why those conditions are happening, not the fact that they are happening at all.

We have research on what can affect heart health, like what things might be linked to it, such as smoking and alcohol. We also know genetics plays a huge role.

So we don't actually have solid answers, actionable answers as to the rise of heart health issues. Look at this analysis[1] regarding how dietary guidelines specifically for fats (saturated, trans) have very little substantial evidence supporting it. Yet this gets repeated by the average person, that fats are the ultimate evil you must avoid. In another study[2] we find that reducing your fat intake still resulted in the same rates of mortality as those who ate more. This is also why more in the space are shifting away from these sort of claims ("only eat x amount of saturated fat per day") and more to general food composition (eg who cares if a fish has saturated fats, eat the fish with vegetables).

It's quite challenging to figure out, everyone has their theories. All I'm saying is we don't actually have the answers yet.

Nestle ? McDonalds ? Burger King ?

Insane prices for insulin?

edit: you really think insulin prices don't have an effect on the lifespans of diabetics?
