What 'Processed Food' Actually Means

You've been told to eat less processed food. Probably more than once, and probably by someone who never said what exactly makes a food 'processed'

So you make a guess. Chips? Obviously. Frozen dinners? Yeah, probably. But then you're standing in the grocery store holding a bag of pre-washed spinach, a carton of plain Greek yogurt, and a can of black beans, trying to figure out if these are technically 'bad' too.

All three were made in a factory. All three came in packaging. All three are, technically, processed.

If that feels confusing, it's not because you're missing something obvious. It's because the advice was never specific enough to follow.

There isn't an official definition

Kind of interesting, actually — federal regulators are still working out how to define "ultra-processed food." The most recent dietary guidelines sidestepped the phrase entirely and used "highly processed" instead, which is a different term that also doesn't have an official definition.

So when someone tells you to cut out processed food, they're using a category nobody has finished defining. That's not a reason to ignore the idea. It is a reason to stop treating it as a rule you are failing to follow.

The four groups researchers actually use

Most nutrition research sorts food by how much it's been changed, not by how healthy it is. The four groups they use are:

Minimally processed. Altered only by things like drying, freezing, pasteurizing, roasting, or bagging. Fresh and frozen produce, plain milk, eggs, dried beans, raw chicken. Bagged spinach lives here.

Cooking ingredients. Pressed or refined out of whole foods and used to cook with. Olive oil, butter, salt, sugar, vinegar, honey.

Processed foods. A whole food with a cooking ingredient added. Usually two or three ingredients total, still recognizable as the original food. Canned beans, canned fish, cheese, fresh bread.

Ultra-processed foods. Built mostly from substances extracted from foods, plus additives you wouldn't have in your kitchen — emulsifiers, colorings, flavor enhancers. Soft drinks, packaged snacks, most frozen ready meals.

Notice what this list isn't doing. It isn't ranking foods by nutrition. Butter and olive oil sit in the same group. So do frozen broccoli and raw ground beef.

Processing isn't the problem

Pasteurizing milk is processing. Freezing green beans at harvest is processing. So is canning tomatoes, fortifying cereal, and washing spinach so you can eat it out of the bag on a Tuesday.

A lot of processing exists to make food safer, last longer, cost less, or take less time. Those are not small things when you have a job, a commute, and forty minutes between getting home and needing to eat.

Dietitian take

Sorting food into "processed" and "unprocessed" isn't a great way to make decisions in the moment. It's too broad to actually help you, and it makes you feel weird about buying a can of beans.

A better question than 'is this processed' to ask: What is this food doing for me?

• Is it giving me protein or fiber I'd otherwise be short on?

• Is it getting produce into my day that I'd otherwise skip?

• Does it make a real meal happen on a night I'd otherwise not eat one?

• Do I actually like it?

Canned beans, rotisserie chicken, frozen vegetables, pre-cut fruit, plain yogurt, bagged salad, frozen fish are all processed to some degree, all a yes to at least one of those questions, and all stuff we build into client meal plans constantly.

The ultra-processed foods you actually enjoy can fit into a balanced diet too. The thing worth checking isn't whether you eat them. It's whether they've quietly taken over most of your week. Not because they're inherently bad, but because they're built to be easy to eat fast and easy to keep eating, which makes it genuinely hard to notice when you've had enough.

Where this lands

You don't have to sort your grocery list into approved and forbidden. Shift the balance instead. A few more meals built from whole ingredients, a few swaps you like just as much, and the rest left alone.

It doesn't need to be perfect. It needs to be something you're still going to be doing in March.

If you want help figuring out what that looks like in your actual week — your schedule, your budget, your groceries — that's what our free 20-minute intro session is for! No meal plan, no food rules, no list of things to cut.
