Isn't plant-based meat just ultra-processed junk?

Short answer: Processed it is. In a Stanford trial, swapping to plant-based meat cut LDL cholesterol; processed red meat is a Group 1 carcinogen.

Exhibit A
The comparison that actually matters

"Ultra-processed" is a category, not a verdict. The question is always: processed compared to what?

SWAP-MEAT trial (2020); WHO/IARC (2015)

The objection

“It’s ultra-processed in a factory with a list of ingredients you can’t pronounce. That can’t be good for you.”

The answer

Some of it is heavily processed. Nobody is pretending a Beyond Burger grew on a tree. But “ultra-processed” is a classification of how a food is made, not proof it harms you, and the test that matters is comparing it to the thing it replaces: meat.

So compare. In the SWAP-MEAT trial at Stanford, 36 adults ate the same diet twice (once with animal meat, once with plant-based meat) for eight weeks each. On the plant products their LDL (“bad”) cholesterol fell by about 10 mg/dL, a clinically meaningful drop, alongside lower TMAO (a cardiovascular risk marker) and a small weight loss. No adverse effects.

Now the other side of the ledger. The WHO’s cancer agency classifies processed meat as a Group 1 carcinogen, the same evidence tier as tobacco for strength of proof rather than danger, with each 50g eaten daily raising colorectal cancer risk by 18%. Bacon and sausages are ultra-processed too, and they carry a cancer warning a veggie burger does not.

None of this makes all plant meat health food. It does mean “ultra-processed” was never the real objection, because the meat it replaces is processed and carcinogenic. Read the label, pick the better-formulated brands, and you still come out ahead.
