what is the difference between a processed food and an unprocessed food? what degree of processing makes a food ultra-processed? what ingredients should I be looking for and why? what is so nutritious about potatoes, and why does frying change anything? what is special about seed oil?

"Processed" is a slightly confusing shorthand for "has undergone processes which either damaged its nutritional properties or added a ton of unhealthy shit for the sake of becoming more appealing and/or easier to preserve and consume".

A chopped apricot or a smoked salmon are in a literal sense processed food, but nobody is referring to that kind of processes. Rather, they're referring to the processes that turn an apricot into a Sachertorte, or a salmon into spreadable salmon-flavoured cheese. Dehydrating, extensive cooking, adding massive amounts of salt/sugar/fats - processes that destroy vitamins and other nutritionally important characteristics and mix the original food with large quantities of unhealthy ingredients.

> spreadable salmon-flavoured cheese

Sounds like cheese to me.

It's a combination where both parts play a key role. Much like a jam needs both fruit and sugar, or a bar of chocolate needs both cocoa powder and cocoa butter; neither component is a small addition, and neither can be omitted.

"I know it when I see it"

Just be aware of whats in your food. I don't look for specific ingredients just learn what the makeup of your food is and decide if you should be eating that. Awareness is 80% of the battle.

Boiled/roasted potatoes are really satiating for their calories. But most people associate potatoes with a lot of fat, like french fries or mashed potatoes which make them very high calorie.

Deep frying anything I think should be a special occasion, you shouldn't be having deep fried food every day or even week, it adds a lot of useless calories. Stir frying is healthier

Seed oils (modern oils like canola, invented in 1974) are suspicious. There is a lot of conspiracy theories out there and not a lot of data, but I try to stay away from it. After all we've been using olive oil for thousands of years, no need to stop.

One rule of thumb is to be wary of anything not sold on the perimiter of a grocery store.

Generally speaking, I think of processed foods as anything padded with sugar, salt and/or fat. Food which comes from a factory, not a farm. Processed foods are digested quickly which has issues. They have a high caloric density with low nutrients due to the sugar,salt+fat.

Think candy, chips, soda, bread, cured meats and things in bags. Low in nutrition, high in calories.
