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.
Evidence from Studies

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.
