Aside from the rare naturally edible-when-ripe cultivar, olives are (mostly) made edible by fermenting and curing them. With salt, yes. And lye, often. Even olives fermented in water are then cured in brine. What saltless olives are you interacting with?
Edit: Also, cooking is very much processing food. It has all the mechanisms to change things and generate relevant pollutants. It changes substances drastically, and different substances differently drastically. Cooking with fire will create smoke, etc. Cooking with overheated teflon cookware will kill your birds. Mechanisms are important.
And, yes, soaking food in water, particularly for the specific purpose of cultivating micro-organisms to destroy the bad stuff in the food and generate good stuff instead, is some intense, microscopic-level processing.
I had just searched on google about ways to make olives edible and got some mixed results. The point I was trying to make was that the way that olives are typically processed to make them edible results in a product that isn’t particularly healthy at least relatively speaking, due to having isolated chemical(s) added to it in its processing.
The main thing I’m trying to say is that eating an isolated component of something we’re best adapted to eat, and/or adding isolated/refined components to that food, will generally make that food less healthy than it would be were we eating all of the components of the food rather than isolated parts.
I think that process, and more complex variations of that process, are essentially what’s being referred to when referring to the process behind processed foods. I think it’s a generally reasonable term with a solid basis.
Hmm, while I don’t think olives in general are unhealthy in the slightest (you can overload on salt if you focus on them too much because they are brined, but that’s reasonable to expect), there is definitely a meaningful distinction between the two types of processing we’re referencing. Nixtamalization isn’t isolating a part of something, it’s rendering nutrients already in the corn more available. Fermenting olives isn’t isolating anything, (though extracting olive oil is), it’s removing substances that make the olive inedible. Same for removing tannins from acorns. Cooking is in main part rendering substances more digestible.
We often combine foods to make nutrients more accessible, like adding oil to greens with fat-soluble vitamins. I do think there’s a useful intuition that leaving out part of an edible food is less advantageous than just eating the whole thing, because we definitely do want to get sufficient nutrients, and if we’re being sated without enough of the ones we can’t generate we’ll have problems.
This intuition doesn’t happen to capture my specific known difficulty with an industrially processed additive, though, which is a mild allergy to a contaminant on a particular preservative that’s commonly industrially produced via a specific strain of mold. (Being citric acid, there’s no plausible mechanism by which I could be allergic to the substance itself, especially considering I have no issues whatsoever with citrus fruits.) In this case there’s rarely a ‘whole food’ to replace—it’s just a preservative.
I would consider adding salt to something to be making that thing less healthy. If adding salt is essential to making something edible, I think it would be healthier to opt for something that doesn’t require added salt. That’s speaking generally though, someone might not be getting enough sodium, but typically there is adequate sodium in a diet of whole foods.

I would disagree that adding refined oil to greens would be healthy overall.
Not sure how much oil we’re talking, but a tablespoon of oil has more calories than an entire pound of greens. Even if the oil increases the availability of vitamins, I am very sceptical that it would be healthier than greens or other whole plants with an equivalent caloric content to the added oil. I believe it’s also the case that fats from whole foods can offer similar bioavailability effects.
At the same time, as far as I’m aware some kinds of vinegar might sometimes be a healthy addition to a meal, despite it’s processing being undoubtedly contrary to the general guidelines I’m defending, so even if I don’t agree about the oil I think the point still stands.
I do think you’re offering some valid points that confound my idea of simple guidelines somewhat, but I still don’t think they’re very significant exceptions to my main point.
We’re talking about a tablespoon of (olive, traditionally) oil and vinegar mixed for a serving of simple sharp vinaigrette salad dressing, yeah. From a flavor perspective, generally it’s hard for the vinegar to stick to the leaves without the oil.
If you aren’t comfortable with adding a refined oil, adding unrefined fats like nuts and seeds, eggs or meat, should have some similar benefits in making the vitamins more nutritionally available, and also have the benefit of the nutrients of the nuts, seeds, eggs or meat, yes. Often these are added to salad anyway.
You probably don’t want to add additional greens with the caloric content of oil to a salad; the difference in caloric density means that 1 tablespoon of oil translates to 2 pounds of lettuce (more than 2 heads), and you’re already eating probably as many greens as you can stomach!
Edit: I should also acknowledge that less processed (cold pressed, extra virgin, and so forth) olive oil has had fewer nutrients destroyed; and may be the best choice for salad dressing. But we do need to be careful about thinking processing only destroys nutrients—cooking, again for example, often destroys some nutrients and opens others up to accessibility.
I typically consume my greens with ground flax seeds in a smoothie.
I feel very confident that adding refined oil to vegetables shouldn’t be considered healthy, in the sense that the opportunity cost of 1 Tablespoon of olive oil is 120 calories, which is over a pound of spinach for example. Certainly it’s difficult to eat that much spinach and it’s probably unwise, but I just say that to illustrate that you can get a lot more nutrition from 120 calories than the oil will be adding, even if it makes the greens more bioavailable.
That said “healthy” is a complicated concept. If adding some oil to greens helps something eat greens they otherwise wouldn’t eat for example, that’s great.
Raw spinach in particular also has high levels of oxalic acid, which can interfere with the absorption of other nutrients, and cause kidney stones when binding with calcium. Processing it by cooking can reduce its concentration and impact significantly without reducing other nutrients in the spinach as much.
Grinding and blending foods is itself processing. I don’t know what impact it has on nutrition, but mechanically speaking, you can imagine digestion proceeding differently depending on how much of it has already been done.
You do need a certain amount of macronutrients each day, and some from fat. You also don’t necessarily want to overindulge on every micronutrient. If we’re putting a number of olives in our salad equivalent to the amount of olive oil we’d otherwise use, we’ll say 100 4g olives, that we’ve lowered the sodium from by some means to keep that reasonable … that’s 72% of recommended daily value of our iron and 32% of our calcium. We just mentioned that spinach + calcium can be a problem; and the pound of spinach itself contains 67% of iron and 45% of our calcium.
… That’s also 460 calories worth of olives. I’m not sure if we’ve balanced our salad optimally here. Admittedly, if I’m throwing this many olives in with this much spinach in the first place, I’m probably going to cook the spinach, throw in some pesto and grains or grain products, and then I’ve just added more olive oil back in again … ;)
And yeah, greens with oil might taste better or be easier to eat than greens just with fatty additions like nuts, seeds, meat, or eggs.

Appreciate the dialogue:)
