Can eating food from old plants and animals shorten lifespan?

Interesting, thanks for sharing!
Interesting, but it is unclear if it is actionable. Most of the food people eat is very young. Probably the oldest food normally eaten is beef from cattle that is 30-42 months at slaughter. Venison from a hunt might be older.
Oxidation damage during storage may be more important.

What about fruit/vegetable?
Right, most vegetables are young, and sprouts youngest, but what about new growth like apples on an old tree? Perrenials like asparagus? This question opens up a can of worms.

Is it because there’s more weirdly-oxidized or Michael adducts or peroxidized lipids on proteins? (do proteins accumulate more macromolecular damage than lipids?) Can plants survive with a higher percent of oxidized lipids than animals?
THIS says NOTHING ABOUT PLANTS
There are people who eat mainly food from their own gardens, who harvest only just before consuming, running from the garden to the kitchen to minimize loss of nutrients. You can do this when you settle down and get a house. Don’t do what I did and get an extremely shady lot so that you can keep your A/C bills low because nothing edible will grow there.
If you have to buy your own food there will always be some question as to its freshness.
I tend to get produce twice a week when I can but I don’t worry about how long it’s been on the shelf or in transport. If I did, I’d be a basket case.
