Heirloom vegetables grow more slowly and spoil much more quickly than modern crops. This is because modern crops have less nutritional value - https://jeroenvanbaar.substack.com/p/data-dispatch-4-the-falling-nutritional
That article recommends eating a better diet. Sure. Seems a bit idealist. Here's some more actionable advice: everyone should take a multivitamin and magnesium glycinate. If you live somewhere that gets a winter take vitamin D too.
I'm speaking from experience here, I used to get sick every winter and my skin would get so dry it would crack and bleed. Take your vitamins.
Partially true but probably the least important ill of the modern age
far more important is the bioaccumulation of pesticides and heavy metals and plastics
and obviously the bioweapons being directly administered into the alveoli
also stress uses up energy and micronutrients faster, this is way more important IMO than vegetables being 10% less nutritious (veggies and fruits are still the healthiest and least degraded thing since the before-fore times)
