Ultra-Processed: The NOVA Test for What's Actually in Your Pantry

You've heard the phrase "ultra-processed foods" everywhere. The 2025 Lancet Series called them a global health threat. The wellness world treats UPF as the new villain. But most people still can't tell you what counts as ultra-processed and what doesn't — because the definition is genuinely fuzzy, and the term is doing a lot of work in one breath.

In this fireside chat, Ashok and Meera Vasudevan hand listeners the literacy tool the conversation is missing: the NOVA classification system. Four simple groups, from whole foods to industrial formulations, that turn a confusing buzzword into a practical pantry test. Ten seconds with any food label, and you'll know roughly where it sits.

The episode also draws a line most wellness conversations don't: processing is not a slur. Fermenting, soaking, sprouting, milling — these are processing too. Idli batter is processed. So is sourdough, miso, and yoghurt. The villain isn't human food preparation. The villain is industrial ultra-processing — formulations engineered for hyper-palatability, packed with additives, designed for a long shelf life and a short attention span.

Honest about the scientific debate (the NOVA framework has genuine critics), generous about the gems (most traditional cuisines are NOVA Group 1–3 by design), and ruthlessly practical about the action: read the back of the box.

Five minutes. Evidence-based. A literacy tool you can use this week.

🎧 New episodes every Tuesday at 5am. 🌱 Pay the Farmer, Not the Pharmacy is a CSAW production.

Transcript

SPEAKER_00 0:02

Welcome to the Pharma, not the pharmacy. This is our show. You know, ultra-processed foods, Mira, is what we're going to talk about today, and this phrase is everywhere. The 2025 Lancet series calls ultra-processed foods, the UPFs, a global health threat. And wellness influencers have made them the new villain. But here's the thing: if you ask the average shopper to point at three ultra-processed foods in their pantry, most of us can't do it. The term is doing a lot of work and it's not always doing it clearly. True.

SPEAKER_01 0:45

So today we want to give you a tool. Not a lecture, not a list of foods to fear, but a tool. Something you can use in 10 seconds with any food label and have a pretty good idea where it sits on the processing spectrum. It's called the NOVA classification system. And once you learn it, you cannot unsee it.

SPEAKER_00 1:09

So let's start with the basics. Nova is a Brazilian classification system, and it groups foods not by calories, carbs, or fats or by micronutrients, but by how it is prepared and processed. Four groups, simple.

SPEAKER_01 1:28

Yep. Okay, so group one, whole or minimally processed foods. An apple, brown rice, a piece of fish, spinach, eggs, lentils. Basically food that more or less, as nature delivers it, may be washed or dried, or at any rate with minimal intervention.

SPEAKER_00 1:46

And group two is culinary ingredients, the things you cook with oil, salt, sugar, butter, vinegar, honey, pressed, refined, or extracted from group one foods, but not eaten on their own. So that's what makes group one foods taste good.

SPEAKER_01 2:07

Yep. And there's group three, which is processed foods, but in the traditional sense. Foods that are made by combining the group one and group two ingredients.

SPEAKER_00 2:18

Right.

SPEAKER_01 2:18

Usually using techniques that have been around for centuries. So cheese, bread, idli and idli batter, pickles without any added preservatives, canned beans, tofu, yogurt, miso, olive oil. These are processed, yes. But processing is not a slur or a bad word. Fermenting, sorting, soaking, sprouting. This is processing. And we've been doing this for thousands of years, and they're good.

SPEAKER_00 2:47

And then there is group four, which is ultra-processed foods. This is where the trouble lives. Industrial formulations made mostly from substances extracted, refined, and recombined in ways your kitchen could never replicate. Long ingredient lists, words you don't recognize, engineered for hyper palatability, designed to sit on a shelf for six months and disappear from the bag in 20 minutes.

SPEAKER_01 3:18

So here's a practical test. Pick up any food package and look at the ingredient list. If you see five things, all of which you could buy at a regular grocery store, say flour, water, salt, yeast, olive oil, you are probably in group three.

SPEAKER_00 3:36

And if you see 22 things, half of which you can't pronounce, with names like modified cornstarch, soya protein, isolates, high fructose corn syrup, natural flavors, and some peculiar numbers and three different emulsifiers, congratulations, you've just discovered group four.

SPEAKER_01 3:56

Yeah. Here are some clear examples. Group four includes most packaged biscuits and snacks and breakfast cereals. It includes instant noodles, sugary drinks and energy drinks, packaged cakes and snack bars, chicken nuggets, hot dogs, most of the low-fat or dietary formulated products. And a surprising amount of these things are marketed as healthy.

SPEAKER_00 4:22

You know that last one matters. Many UPFs, ultra-processed foods, are dressed in wellness clothing. Beware. Protein bars, plant-based meat substitutes, flavored yogurts with 18 ingredients. Just because something says high protein or gluten-free doesn't make it group one.

SPEAKER_01 4:43

So now we want to be honest about something. The NOVA framework also has critics. Some respective scientists argue it's too broad that lumping every group 4 food into the bad category misses an important nuance. A whole grain breakfast cereal, for example, which has added vitamins, is not the same as a sugary cola.

SPEAKER_00 5:07

You know, that's criticism is fair, Mila. Not every UPF is equally harmful, but the Lancet series made a strong case that the overall pattern does matter. When UPFs make up half of someone's daily calories, which is now the norm in many countries, the dietary pattern itself becomes the problem. The displacement matters. Every UPF meal is a meal that isn't a group 1, 2, or 3 meal.

SPEAKER_01 5:40

Yeah. So we are not saying never eat anything from group 4. We are saying know what it is when you do eat them.

SPEAKER_00 5:48

And so here's the good news. Most traditional cuisines around the world are built almost entirely from group 1 to 3. A Mediterranean meal, vegetables, olive oil, fish, bread, cheese sits in group 1 to 3. A Japanese meal, rice, fish, miso, vegetable pickles, same. An Indian thali, lentils, vegetables, rice, it be yogurt, spices, the same. A Mexican home cooked meal, bean, corn, tortillas, vegetables, salsa, exactly the same.

SPEAKER_01 6:19

So the further you stray from how grandmother's cooked, essentially, the more group 4 enters your diet. So cook the way grandmother's cooked in any cuisine. And the problem mostly takes care of itself. Three takeaways here today.

SPEAKER_00 6:36

So one, processing is a spectrum, not a slur. Yogurt and idli battered are processed through. The villain is industrial ultra processing. Yes.

SPEAKER_01 6:48

Secondly, the Nova test takes ten seconds. Long ingredient lists, words that you do not recognize, designed for long shelf life, that's group four. Trust this trust.

SPEAKER_00 7:00

And three, cook the way grandmothers cooked in any cuisine.

SPEAKER_01 7:04

Read the back of the box.

SPEAKER_00 7:06

And eat from the front of the kitchen. I'm Mashok Pasi Devan.

SPEAKER_01 7:11

And I'm Mira. This has been Pay the Farmer, not the Pharmacy. Affordable Wellness, one plate at a time.
