Understanding the NOVA classification system can help you make sense of why whey protein powders are classified the way they are. While the framework is relatively straightforward, it’s often misunderstood, particularly when it comes to products with very short ingredients lists.
Breaking Down NOVA for Protein Powders
The NOVA framework groups foods according to the nature and extent of industrial processing.
Group 1 includes unprocessed or minimally processed foods such as fruit, vegetables, grains, milk, unprocessed meat, and eggs.
Group 2 includes processed culinary ingredients like oils, butter, sugar and salt.
Group 3 includes processed foods made by combining Group 1 and Group 2 ingredients, such as canned fish, bacon, artisan cheese or freshly baked bread.
Group 4 includes ultra-processed foods (UPFs) produced using industrial processes and formulations that can’t typically be replicated in a home kitchen.
Milk is a Group 1 food. However, producing whey protein concentrate involves separating whey from milk, filtering it, concentrating it and drying it into a powder. Because of these industrial processing steps, whey protein concentrate is classified as NOVA Group 4.
Why Ingredients Still Matter
Although all whey protein powders are classified as NOVA Group 4, they are not all formulated in the same way.
A protein powder containing only whey protein concentrate receives the same NOVA classification as one containing emulsifiers, gums, artificial sweeteners, flavourings and other ingredients designed to modify taste, texture or shelf life.
The classification reflects how the protein powder is produced, not how many ingredients it contains. That's why two products can share the same NOVA category while containing very different ingredients.
Reassuringly, all of our whey protein powders are free from the additives most associated with UPF concerns.
Making Sense of Minimally Formulated vs Heavily Formulated
The NOVA system doesn’t distinguish between different types of Group 4 foods. That means a single-ingredient whey protein concentrate and a more heavily formulated protein powder both receive the same classification.
For many consumers, that’s where reading the ingredients list becomes useful. Rather than relying on the NOVA category alone, it helps to consider how a product has been formulated and whether its ingredients align with your own preferences. If simplicity is important to you, choosing a minimal-ingredient whey protein powder may be a good place to start.
At The Organic Protein Co., we’re clear that our whey protein cannot be classed as UPF-free because it is part of NOVA Group 4. This classification is true of all whey protein concentrates, regardless of brand. Our focus instead is on using gentle cold filtering methods, and keeping the ingredients list simple to produce high-quality undenatured whey protein.
The NOVA classification is a useful starting point, but not the whole story. Understanding both how a protein powder is produced and what’s in it gives you a fuller picture when comparing products. To learn more, read our full guide to whey protein and ultra-processed foods here.
