Wait - this does not sound very scientific, @sciam.
"The level of every nutrient in almost every kind of food has fallen between 10 and 100 percent"

This is complete bullshit,
@sciam. You might mean certain minerals, such as copper, but I bet that main nutrients such as protein, carbohydrates etc have remained remarkably the same.6 replies 20 retweets 119 likesShow this thread -
Let's trace this back. The citation in the
@sciam article links to an article on EcoFarming Daily, which links to this 2007 paper about mineral changes (note: not nutrient changes):https://journals.sagepub.com/doi/10.1177/026010600701900205 …6 replies 5 retweets 66 likesShow this thread -
This 2007 paper looked at mineral levels in main food items such as meat and milk and vegetables. Copper appears to be the one that decreased a lot in food items from 1940 to 2002.

But,
@puddleg pointed out in his earlier tweet that copper was used as a fungicide in the 1940, but not as much in 2002.3 replies 4 retweets 62 likesShow this thread -
One could also argue that measurements of minerals in 1940 might have been done by a different method than in 2002. I did not investigate if methods were really different, though. Just my late night 2 cents.

There's been research on this in the past - it's almost impossible to compare the early estimates of mineral density with modern ones, and doing so in this context is risible https://www.sciencedirect.com/science/article/pii/S0889157516302113 …

Replying to @GidMK @MicrobiomDigest and
The old literature even has errors. Fe content of spinach famous for years via Popeye, had an order of magnitude error I recall from memory. Twitter check my memory on this
