The Claim

Peanut butter consumption is not significantly associated with reduced total or cause-specific mortality, despite comparable nutrient profiles to whole peanuts, suggesting that processing or added ingredients may eliminate potential health benefits.

In plain English

Eating peanut butter does not lower the risk of dying from any cause, even though it has similar nutrients to whole peanuts, meaning processing or added ingredients might remove any health benefits.

See the scientific wording

Peanut butter consumption shows no significant association with reduced total or cause-specific mortality, despite similar nutrient profiles to whole peanuts, indicating that processing or added ingredients may negate potential health benefits.

Why this might work

Peanut butter has extra sugar and salt added during processing. These ingredients cause the body to produce more inflammation and make it harder to control blood sugar and fat levels, which cancels out the good effects that come from peanuts themselves.

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

    Eating whole peanuts lowers your risk of dying from diseases, but eating peanut butter doesn’t seem to help—suggesting that processing or added sugar and salt might cancel out the good stuff.
