Micronutrients & recovery
Consuming five or more servings of fruit and vegetables daily is associated with a significantly lower risk of all-cause and cardiovascular mortality compared to lower intake, with diminishing returns observed beyond this threshold.
Aim to eat five servings of fruits and vegetables every day. This level of intake is associated with the lowest risk of death from heart disease and other causes. Eating more than five servings does not appear to offer additional mortality benefits, so focus on consistency rather than excessive quantities.
There was a threshold around five servings of fruit and vegetables a day, after which the risk of all cause mortality did not reduce further.
Why this rating
Large sample size (833,234 participants) and long follow-up (4.6-26 years) in a meta-analysis of prospective cohorts, though observational design limits causal inference.
