> eat food, mostly plants, not too much.

If the state of physics was "stuff falls, heat sticks around, light goes fast" I think it'd be fair to describe that as "abysmal".

Something being simple doesn't mean it's incomplete or wrong.

Health/nutrition is a spectrum but no one will tell you to eat a bag of chips a day and rinse your mouth with coke

Of course it's incomplete. Any explanation of nutrition that doesn't include mention of at least calories, macronutrients and micronutrients isn't useful for understanding what's actually going on or being able to make an effective nutrition plan.

There are hundreds and hundreds of studies linking ultra processed food to all kind of health issues, and not a single one linking ultra processed food to any kind of benefits, not a single one praising their nutritious values.

The only benefits ever listed are shelf life, convenience, better margins for the producers, etc.

> praising their nutritious values [...] The only benefits ever listed are shelf life, convenience

Availability is the most important value of nutrition, above all else. I expect your comment was made having more nuance, but that just highlights the importance of a clear definition. Without it we are left to guess at what it is you mean.

Sustenance is a health benefit. Shelf life is a health benefit. Convenience is a health benefit.

If you have options when choosing food, a framework that helps you choose the better option is useful. The history of food production is mostly centered around developing options that provide, as a baseline, the three advantages you casually dismiss.

> Shelf life is a health benefit.

Then why don't we pickle or ferment things anymore ? Ah right because it's not as profitable.

Listening to you guys it seems like Americans in the 80s were starving and we should praise microwave meals for saving us from extinction.

Funny, you left out "curing" from that list.

All three preservation techniques are practiced today as they have been since antiquity. It is not clear to me where food so preserved are likely to fall on the processed / ultra-processed spectrum...

Microwave meals go back to the 1950s. If anything the standard American diet was worse in the 1980s. The idea of "health food" was only starting to go mainstream.

The state of physics for most human bodies is "avoid things that are too hot/cold, electricity and heavy things requiere more energy to move, things fall when thrown up"

With those kind of basic ideas you can mostly survive and figure your way around. No one needs to check spin on electrons when living their day to day. Or the mass of a neutron star versus a blackhole

Similarly, nutrition science can be extremely specific about gut microbiome compositions and its effect in regulating specific hormones and so on. But most humans just need the guidelines of dont over eat, have mostly fish/legumes and veggies and be active (strength training and regular walks) to have a healthy life.

no one needs to know the exact frequency and voltage of your plug to be taught to not stick your giners on the wall, and no one needs to know the exact victamin C and iron content of spinach to know its healthier than ultraprocessed chips
