Whole Foods vs. Processed Foods: What Actually Belongs on Your Plate?

March is National Nutrition Month®, a time to cut through nutrition noise and refocus on what truly supports long-term health.

If you've spent any time scrolling through social media lately, you've probably stumbled across some version of these claims:

• "Never eat processed food."

• "If you can't pronounce it, don't eat it."

• "Only eat whole foods."

It's a lot, especially when the people saying it often don't have formal nutrition training, yet speak with total confidence. So let's slow down and talk about what the evidence actually says.

Let's Start with a Story You Might Recognize

Picture this: you've had a long week. It's 6 PM, everyone's hungry, and the last thing you have time for is prepping a gourmet meal from scratch. You reach for a can of chickpeas, a bag of frozen spinach, and some whole grain bread and throw together a quick, filling dinner.

Was that a "bad" food choice? According to some corners of the internet, yes. But here's what we'd tell you as registered dietitians: not even close.

That dinner was nourishing, practical, and exactly what real healthy eating can look like.

First, We Need to Talk About What "Processed" Actually Means

Here's something that might surprise you: almost everything in the grocery store is processed in some way. Processing simply refers to any change made to a food before it reaches you such as washing, freezing, canning, drying, pasteurizing, grinding. By that definition, your frozen broccoli? Processed. Your canned beans? Processed. Plain Greek yogurt? Also technically processed.

And here's some historical context worth knowing: food processing isn't a modern invention gone wrong. Ancient civilizations dried fish, fermented milk into yogurt, cured meats with salt, and ground grains into flour. Processing has always been part of how humans eat safely and sustainably.

The issue isn't processing itself. It's the degree and purpose of it.

Enter: The NOVA Classification

Researchers at the University of São Paulo developed a system called NOVA that helps us think about this more clearly. Rather than labeling foods as simply "good" or "bad," NOVA organizes them by how much and why they've been processed:

• Group 1 — Unprocessed or Minimally Processed: Fresh produce, eggs, plain grains, milk. Foods in their most natural state.

• Group 2 — Processed Culinary Ingredients: Things like oil, butter, sugar, and salt used in cooking, not typically eaten on their own.

• Group 3 — Processed Foods: Canned beans, cheese, freshly baked bread. Still nourishing, just altered for convenience or preservation.

• Group 4 — Ultra-Processed Foods (UPFs): This is where the real concern lives: sodas, packaged snack cakes, candy, many fast-food items. These are industrial formulations, often engineered to be hyper-palatable and shelf-stable.

The World Health Organization has raised legitimate concerns about diets high in ultra-processed foods and their links to chronic disease. But …and this is important…that doesn't make all processed food the enemy. It's about the overall pattern, not a single food choice.

So What's the Real Problem with Ultra-Processed Foods?

Think of it less like toxicity and more like displacement. Ultra-processed foods tend to be calorie-dense, low in fiber, and light on the vitamins and minerals your body needs. When they make up the bulk of what you eat day after day, they crowd out the more nourishing stuff:  the fiber, the iron, the omega-3s, the protein.

But enjoying birthday cake? Grabbing a packaged snack between meetings? Using convenience foods to get dinner on the table on a Tuesday night? That's not a nutrition problem. That's called being human.

The issue isn't a single ingredient or a single snack. It's when ultra-processed foods become the foundation rather than the occasional player.

And Let's Be Real About Real Life

Food choices don't happen in a vacuum. Access to grocery stores, work schedules, income, transportation, kitchen equipment, and cultural food traditions all shape how and what we eat. A nutrition philosophy that ignores those realities, one that says "just eat fresh, organic, homemade meals",  isn't just impractical for many people. It's inequitable.

Canned beans are affordable and packed with fiber and protein. 

Frozen fruits and vegetables reduce food waste and retain most of their nutrients. 

Fortified cereals can fill real nutritional gaps. 

These foods make healthy eating accessible, and accessibility matters.

What a Balanced Approach Actually Looks Like

Across the nutrition science community from the American Heart Association to Harvard's School of Public Health to the Academy of Nutrition and Dietetics, there's broad consensus on the core message: build your diet around nutrient-dense, whole foods, limit ultra-processed options, and focus on dietary patterns. That's the foundation we work from, regardless of what's happening in the political conversation around federal nutrition policy. Here's what that looks like in practice:

Use MyPlate as your starting point. Half the plate fruits and vegetables, lean protein, whole grains, and dairy or fortified alternatives. It's a simple, flexible framework that you can apply at home, at a restaurant, at a party.

Read nutrition labels, but don't obsess. Look at fiber content, added sugars, and protein. A shorter ingredient list is often a good sign, but it's not a hard rule. Context matters.

Prioritize nutrient density in whatever form works for you. Frozen vegetables count. Store-brand canned beans count. A rotisserie chicken on a busy night counts.

Honor your hunger. Eating regularly, tuning into your body's signals, and allowing all foods in moderation helps break the cycle of overeating, guilt, restriction, and rebound. Food should nourish your body and it should also bring some joy.

The Bottom Line

Whole foods form the foundation of a health-supportive diet. But processed foods absolutely have a place, and ultra-processed foods don't need to be feared. They just shouldn't crowd out the good stuff.

The goal isn't a "perfect" pantry or a flawless food diary. It's a sustainable pattern built around nourishment, accessibility, balance, and a genuinely healthy relationship with food. That's what the evidence supports and it's what we work toward with every client we see.
