Science fact-checking · Aug 6, 2026Contrary to the post, higher protein is linked to LOWER mortality in older adults. And for cancer? No increased risk in meta-analyses. It's the source that matters—animal protein raises heart risk, plant protein cuts it. https://s.fitbodyscience.com/PkS7k6

The breakdown
High protein intake isn't clearly harmful — the evidence is mixed.
Looking at the research, it's a mixed bag. Some studies do find that high protein intake is tied to higher risks of diabetes and death, especially in certain populations. But other studies find the opposite — that more protein, particularly from plants, is linked to a lower risk of dying. For cancer, the evidence actually points away from a higher risk. And for heart disease, it depends: animal protein might raise risk, while plant protein might lower it. These are mostly observational studies, so they can't prove cause and effect.
Bottom line
So while there's some support for parts of the claim, the overall picture is far from settled — and the type of protein and who's eating it makes a big difference.
ReliabilityThe evidence is mixed — some research supports it, some contradicts it.
