The Claim

Nut consumption is associated with reduced all-cause mortality, with the effect plateauing at approximately 15–20 grams per day, beyond which no additional reduction in mortality is observed, as determined by nonlinear dose-response analyses across multiple outcomes.

In plain English

Eating 15–20 grams of nuts per day is linked to lower risk of death from any cause, and eating more than that does not lower the risk further.

See the scientific wording

The association between nut consumption and reduced mortality from all causes appears to plateau at approximately 15–20 grams per day, with no further benefit observed at higher intakes, based on nonlinear dose-response analyses across multiple outcomes.

Why this might work

Eating a small amount of nuts each day lowers harmful inflammation and oxidative damage in the body, which protects against heart disease, cancer, lung disease, and infections. Once the body has enough of these protective compounds, eating more nuts doesn’t add any extra protection.

    Eating a small handful of nuts (15–20 grams) each day helps people live longer, but eating more than that doesn’t help even more — it’s like filling a cup: once it’s full, pouring more doesn’t change anything.
