Reminder to get back into hydroponics or some home scale growing of at least leafy greens.
A lot of people who eat this produce and don't take any supplements are healthy and doing fine. If the nutrient levels have really fallen so much, then, how come malnutrition isn't an epidemic?

Malnutrition isn't as visible as obesity though, you can be a fat fuck and still malnourished in some aspects, but if you're already fighting high blood pressure and diabetes these issues are way down your list of problems. It can be very subtle like micro gut health, teeth health, long term bone health, children not growing as tall as they could, &c.
Virtually no metrics are going in the right direction in the US when it comes to nutrition: https://globalnutritionreport.org/resources/nutrition-profil...

Earlier quoted context omitted.
It does mention those reasons and others, however all those reasons directly contradict the article's next point "If all you care about is nutrient content, SPEED is the only factor that matters". Seems like all these other factors should matter too! Surely not every farm is equal in these respects...
> Seems like all these other factors should matter too! The way I read it was that there are some minerals that are no longer there to begin with because they're simply not in the soil. For nutrients (like vitamin C) created as part of the growing process, speed is the only factor that matters. So yes, it does matter but unless you have a way of knowing which farm(s) the produce came from and what their soil mineral…
That's exactly the problem, fertilisers don't necessarily fully replenish the soil in every single micro nutrient so if you cultivate corn on the same parcel for 60 years you might very well have completely depleted the soil of some of them
You can grow very nice fruits and veggies on NPK fertilisers alone without caring for any of the other nutrients, nobody buys tomatoes because they're nutritious, we buy them because they're big and red. And that's why most taste like water and have no nutritional values today
From article “Side note on frozen produce: The post above is about fresh produce only. A potentially appealing alternative may be buying frozen produce, which on average has equal or higher nutritional content than fresh. This is because frozen produce is picked at peak ripeness then frozen shortly after, locking in most of the nutrients at the expense of appearance/texture/flavor.”
I read that high temperatures degrade some nutrients (vite ?), not all at the same speed/temp. What about frozen? I’m happy to know most of the nutrients handle it, is there known exceptions?
Freezing generally means lowered rate of chemical reactions, water no longer flows, etc. So it makes logical sense that freezing keeps the nutrients intact.
> That means it had been a year since the apples he bought were actually picked I've been saying for a while that instead of focusing on "best by" dates, food suppliers should be forced to put on the harvest or manufactured date. "Fresh" Apples being sold after a year is nothing compared to how old some of the food you by in the freezer, or boxed section. Manufacturers and store owners are the ones that benefit the m…
Supplementation with ascorbic acid in shelf-stable tablet form seems like a reasonable compromise.
> If you walk into a booth and that vendor is selling over 5 types of produce, there's no way they all ripened at the same time. This makes me think this person simply has no idea how growing food works at all.
Vitamin C sufficiency is very important to humanity, and freshly picked produce very expensive. Vitamin C seems to be largely unique among nutrients in how fragile it is, being destroyed with any significant storage or cooking. Supplementation with ascorbic acid in shelf-stable tablet form seems like a reasonable compromise.
While one can get enough vitamin C from one red bell pepper per day or from one or two kiwi fruits, depending on size, where I live, in Europe, the equivalent amount of pure powder of ascorbic acid is more than ten times cheaper. It also does not need frequent shopping.
