Eating fruit every day is linked to living longer, but eating more than two servings a day doesn’t make much of a difference.

Scientific Claim

Each additional daily serving of fruit is associated with a 6% lower risk of all-cause mortality, with no further benefit observed beyond approximately two servings per day.

Original Statement

The summary estimates were 0.94 (95% confidence interval 0.90 to 0.98; P=0.002) for each additional serving a day of fruit... We also found evidence of a non-linear association for fruit (P=0.01 for non-linearity)... A lower risk of all cause mortality was observed in association with higher fruit consumption at about two servings a day (hazard ratio 0.83, 0.78 to 0.88).

Assessment Explanation

The claim uses 'associated with' and reports hazard ratios from observational data, which is appropriate. Non-linear thresholds are presented as observed patterns, not causal mechanisms.

Eating one more serving of fruit each day lowers your chance of dying from any cause by about 6%, but eating more than two servings a day doesn’t make you any healthier in terms of living longer.
