This advice is firmly rooted in the science of preventive nutrition. Regarding fiber, a major meta-analysis by Reynolds et al. (*The Lancet*, 2019) confirms that a daily intake of 25 to 29 g is associated with a significant improvement in longevity (level of evidence: meta-analysis of prospective cohort studies). Concerning produce, the 500 to 600 g target aligns with data from a vast meta-analysis by Aune et al. (2017) showing that life expectancy benefits increase up to 800 g per day. However, other work, such as the meta-analysis by Wang et al. (2021) in the journal *Circulation*, suggests a plateau in physiological benefits starting at 5 daily servings, or approximately 400 g. The emphasis on unprocessed products is valuable, as the natural plant matrix maximizes micronutrient intake and actively supports the gut microbiome. Thus, the target proposed by the creator is robust, scientifically validated, and ideal for optimizing overall daily vitality.
