Plant-Based vs Vegan: What the Label Actually Means

The language changed, and most people have not noticed that the meaning changed with it. “Vegan” is a strict claim about what is not in the food. “Plant-based” is a description of what the food is mostly made of — and it is doing a great deal of marketing work.

They are not interchangeable, and neither of them is legally defined.

Why the word changed

Ten years ago this was all called vegan. The shift to plant-based was deliberate and it worked, because the two words ask different things of you.

Vegan is an identity. It carries an ethical position, and it asks you to join something. Plant-based asks nothing — it describes a meal rather than a person, which means a committed meat eater can order a plant-based burger on a Tuesday without feeling like they have signed up to anything. The audience went from people who had made a decision to everyone willing to try one dish, and the market followed.

That is a genuine win for how much good food is now available. It also made the label vaguer, which is where it starts to matter.

Neither term is regulated

There is no FDA definition of “plant-based,” and no FDA definition of “vegan” either. As Today’s Dietitian sets out, these are marketing terms with no governing body controlling their use. Manufacturers still cannot make claims that are untruthful or misleading, but what counts as misleading is open to interpretation.

The practical consequence is the thing to remember: a “plant-based” label does not guarantee there are no animal ingredients. A plant-based burger can arrive with dairy cheese and egg-based mayonnaise and the front of the package is not lying to you, because the patty was the claim.

What the certifications actually cover

Two third-party seals do more work than the words do, and they are not the same.

Certified Vegan approves products with no animal-derived ingredients, and covers both foods and non-foods. This is the seal to look for if avoiding animal products entirely is the point.

Certified Plant Based runs under the Plant Based Foods Association, which owns the NSF International labelling programme. It covers plant-based alternatives to meat, egg and dairy — not all plant foods. One detail worth knowing: it permits up to 10% of the product formula to come from ingredients that are neither plant nor animal in origin.

Neither seal is a nutrition claim. A product can be certified and still be heavily processed and high in sodium. These labels tell you what is in it, not whether it is good for you.

How to read a label in ten seconds

• Ignore the front of the package. That is where the marketing lives.
• Read the ingredients list. It is the only part that has to be accurate.
• Check the allergen line. “Contains milk” or “contains egg” settles the question instantly, and it is required.
• Look for a seal if it genuinely matters to you — ethically, religiously, or because of an allergy.
• In restaurants, ask about the whole dish, not the headline item. The patty is usually not the problem; the sauce and the bun are.

So which word should you use?

Use plant-based when you are describing how you eat, or what a meal is built from. It is the current term, it is broader, and it does not misrepresent you as stricter than you are.

Use vegan when it is a requirement rather than a preference — telling a host, a server or a kitchen what you cannot eat. In that situation the older, narrower word is the more useful one precisely because it is unambiguous, and swapping it for the fashionable term invites a dish with butter in it.

We cook mostly plant-based here. Our black bean and quinoa burgers and homemade refried beans are both fully vegan in the strict sense, and the Tex-Mex quinoa stuffed peppers are vegetarian — which is exactly the distinction this article is about.
