If you're not used to eating a lot of produce, you can build it into your diet slowly, she said. Most meta-analyses and systematic reviews support that regular MVPA improves various aspects of cognitive function including executive function EF , language ability, visuospatial ability, and memory in older adults with cognitive impairment Chen et al.

When physical activity was directly monitored, participants engaging in recommended levels of MVPA had lower incidence of cognitive impairment and better maintenance of EF and memory Zhu et al. The Physical Activity Guidelines for Americans state that some benefits of physical activity on cognitive health occur immediately after a session of MVPA acute effect ; these include reduced anxiety, improved sleep, and improved cognitive function Piercy and Troiano, With regular MVPA by older adults with or without impaired cognitive health chronic effect , even greater cognitive benefits are experienced including improvements in EF, attention, memory, crystallized intelligence, and processing speed Weng et al.

The substantial cognitive benefits observed with at least min per week MVPA are further amplified when MVPA is increased to min per week. Habitual walking in late adulthood has been correlated with higher gray matter volume, coincident with reduced risk of cognitive dysfunction Erickson et al.

Flavonoid benefits coincident with physical exertion are in part due to antioxidant and anti-inflammatory effects, but also since these polyphenols activate the same adaptive cell signaling pathways as physical exertion, they are believed to complement adaptive benefits of exercise and support performance Hurst et al.

Moderate-to-vigorous physical activity combined with flavonoid ingestion may improve post-exercise metabolic recovery Hurst et al. Effects of MVPA and flavonoid ingestion may be mediated in part through elevations in circulating gut-derived phenolic metabolites, but this linkage has not yet been conclusively established Nieman et al.

MVPA does enhance the release of gut-derived phenolic metabolites following chronic flavonoid ingestion. In a randomized trial with long-distance runners featuring a day intervention with a flavonoid-rich supplement or placebo , serum metabolic signatures from colonic flavonoid metabolites derived from green tea or berries were significantly elevated for at least 14 h coincident with a 3-day intensified exercise period, and these changes persisted through post-exercise recovery Nieman et al.

Microbial metabolites were dramatically elevated once the workout commenced — the release of the metabolites into plasma was stimulated by physical exertion. In another study, the combination of 2 weeks of flavonoid supplementation and acute exercise both 45 min brisk walking and 2.

These data indicated that acute exercise bouts both brisk walking and intensive running combined with flavonoid supplementation, and an elevated fitness status associated with habitual running, were linked to elevations in plasma levels of gut-derived phenolics.

Figure 3. Post-exercise change for 15 selected and grouped plasma gut-derived phenolics. P -values indicate contrasts with the placebo—sit group. Data are represented as means with standard errors of the mean. Several underlying mechanisms could explain these results including flavonoid- and exercise-induced changes in gut permeability and transporter function, increases in gut microbiota richness, and altered gastrointestinal motility and transport rate Nieman et al.

Chronic MVPA can modify the composition and functional capacity of the gut microbiota Hughes and Holscher, Cross-sectional human studies have revealed greater α-diversity and an enriched profile of short chain fatty acids SCFAs in athletes compared to sedentary controls Barton et al.

One examination of phenotypic features across 3, individuals found a linkage between microbiome diversity and MVPA frequency and duration that was independent of major dietary factors and BMI Manor et al.

The interaction between MVPA and the gut microbiota is bidirectional. As already noted, flavonoids are catabolized by and influence composition of the microbiota, and exercise stimulated the bioavailability of flavonoid metabolites Nieman et al. The gut microbiota also has an influence on exercise performance by producing SCFAs that increase muscle blood flow and insulin sensitivity, and can be utilized as fuel Hughes and Holscher, It is therefore reasonable to posit that the connection between physical activity e.

Figure 4. Higher flavonoid intake may influence cognitive function by augmenting gut microbial diversity and functionality and increasing circulating levels of gut-derived phenolic metabolites.

Moderate-to-vigorous physical activity MVPA adds to this effect by enhancing the release of gut-derived metabolites and improving cognitive function.

A complex interaction of factors lifestyle, diet, genetics, and environment all appear to exert influence on cognition in the aging brain. Emerging evidence suggests that there may be potentiating interactions between some of these, including flavonoid intake, microbiome, and physical activity levels exercise.

What are the mechanisms responsible for the benefits to cognition, and how can they be fully demonstrated? We hypothesize that it is the phytoactive metabolites from flavonoid ingestion, after catabolism at the gut microbiome level , that interact with cellular and molecular targets signaling pathways to improve neuron connectivity and promote vascular and peripheral flow in the brain.

Exercise has demonstrated ability to provoke a surge of these phytoactive flavonoid metabolites into circulation. It follows that the positive cognitive benefits from dietary flavonoids and regular moderate exercise may be a consequence of the enhanced circulation of gut-derived flavonoid metabolites, mediated by the activities of the colonic microbiota.
