This is almost certainly not true. Outside of heavy metals there are very few things that "accumulate" in the body and I can't find any papers mentioning nut toxins having this effect.

There is literally an article on the front page about PFAS bio accumulating. Look harder.

Where is the evidence that these are higher in nuts and fruit than in meat and dairy?

The article you mention doesn't answer this question. Read harder

The first study[1] I could find that included analysis of vegan vs non-vegan diets' correlation with blood PFAS levels suggest that vegan diets are negatively correlated with some classes of PFAS (and neutral with the other classes analyzed): "The strongest correlations with food groups, derived from a food frequency questionnaire, were observed between levels of PFOA and water consumption (in case of the total study population, n = 72), and between levels of PFOS as well as PFNA and the consumption of ‘meat and meat products’".

I'm not proposing that a single study is proof, but I'm default-skeptical of dietary claims without strong evidence, especially ones that comport with other aspects of worldview or preference.

PFAS is a “plant defense mechanism”?

You'll note I wrote "there are very few things", not NO things. Read more carefully before rage posting, please.

If he had said “Very few people has actually been to the moon”, would you had commented “Here’s an article about an astronaut.”?
