Here’s a stat that should make you pause: a recent study tracking over 63,000 adults found that ultra-processed plant-based diets increased cardiovascular risk by up to 40% compared to whole-food plant-based diets.
Let that sink in. Not all plant-based food is health food. And the difference between “plant-based” and “healthy” is getting wider every year.
The Research
This study came from INRAE (France’s National Research Institute for Agriculture, Food and Environment) and was covered by ScienceDaily in late 2025. Researchers followed a large cohort and compared cardiovascular outcomes across different types of plant-based diets.
The key finding was straightforward. Diets built around minimally processed, nutrient-dense plant foods significantly reduced cardiovascular risk. But when those same plant foods were ultra-processed — think packaged veggie burgers, plant-based deli slices, vegan cheese with 20 ingredients — the protective benefit disappeared entirely. In some cases, the risk actually went up.
What Counts as “Ultra-Processed”?
The distinction isn’t about whether food comes from plants. It’s about what happens to those plants before they reach your plate.
Minimally processed plant foods: A can of chickpeas. A block of tofu. A bag of brown rice. Frozen broccoli. Peanut butter with two ingredients. These are foods that are close to their original form.
Ultra-processed plant foods: Veggie burgers with ingredient lists you need a chemistry degree to read. Plant-based “chicken” nuggets. Vegan ice cream made from a cocktail of oils, gums, and emulsifiers. Protein bars marketed as healthy but loaded with processed soy isolate and sugar alcohols.
Again, these aren’t evil foods. But building your entire diet around them — thinking you’re being healthy because the label says “plant-based” — is a trap the data now clearly shows.
Why This Keeps Happening
The plant-based food industry has exploded. That’s mostly good. More options, more accessibility, more people trying plant-based eating. But it also means corporations are doing what corporations do: engineering processed products that hit the right taste and texture notes, slapping a green label on them, and marketing them as healthy alternatives.
The result is a grocery store aisle full of products that are technically plant-based but functionally similar to the processed food they’re replacing. Swapping a beef hot dog for a plant-based hot dog made from methylcellulose, soy protein isolate, and modified food starch doesn’t move the health needle.
The Simple Fix
Cook from whole ingredients more often than you eat from packages.
This doesn’t mean you need to become a scratch-cooking purist. It means that most of your dinners should be built on actual vegetables, grains, beans, and spices rather than pre-made products.
A chickpea curry with coconut milk and spinach over rice. A black bean taco bowl with fresh salsa and avocado. A bowl of lentil soup with crusty bread. These are simple, quick, whole-food meals that take 20-30 minutes and deliver the cardiovascular protection the research supports.
