The Claim

Nut intake exhibits a nonlinear relationship with mortality risk, with the greatest reduction in mortality risk observed at an intake of 10 grams per day and reduced benefit at higher intakes.

In plain English

Eating 10 grams of nuts per day is associated with the lowest risk of death; eating more than that provides less additional benefit.

See the scientific wording

The relationship between nut intake and mortality risk is nonlinear, with the greatest benefit observed at 10 grams per day and diminishing returns at higher intakes, suggesting an optimal intake level for mortality reduction.

Why this might work

Eating about 10 grams of nuts daily lowers chronic inflammation and cell damage in the body, which protects organs and prevents diseases that cause early death. Eating more than that does not add more protection because the body’s repair systems become fully saturated.

  1. Study: Relationship of tree nut, peanut and peanut butter intake with total and cause-specific mortality: a cohort study and meta-analysis.

    Eating about a small handful of nuts a day (10 grams) is linked to the biggest drop in risk of dying from diseases like heart disease or cancer. Eating more than that doesn’t help much more.
