Still, more research is needed to understand how probiotics may regulate mood

Anthocyanins and mood regulation -

The brain is the center of the nervous system: it maintains centralized control over the other organs in the body and regulates sensory information and muscle activity. The brain also controls the secretion of hormones, which act as chemical messengers allowing different body parts to communicate.

A healthy brain allows a person to make sense of the world, remember, learn, play, and focus. It also allows them to manage information, use judgment, and maintain logic and perspective. When brain health is impaired, there can be mood imbalances , such as depression and anxiety ; problems with cognition , focus, and memory; and issues with muscular movements and balance.

Blue and purple plant foods are rich in antioxidants, especially those that act to protect the brain and nervous system from oxidative stress and inflammation caused by free radical damage.

Anthocyanins are a group of water-soluble polyphenolic compounds that make up the deep blue and purple pigments found in plant foods. They are rapidly absorbed and can cross the blood-brain barrier to exert their benefits on brain cells.

While the bioavailability of anthocyanins is low, they are transported to the brain where they can concentrate. Furthermore, the metabolites produce an abundance of biological effects, including antioxidant and anti-inflammatory activity and neurological protection.

Brain health is largely impacted by the health of the gastrointestinal microbiota. The signaling pathway, referred to as the gut-brain axis , facilitates a line of communication between gut bacteria and the central nervous system. The signaling system impacts neuroimmune and neuroendocrine signaling, and the species of bacteria present dictate whether the messages sent are health-promoting or disease-promoting.

The species in the microbiome communicate with the brain and directly impact the messages from the hypothalamus to the rest of the body. Disease-promoting bacteria will communicate with the brain and send messages that can activate the immune system.

These messages are responsible for neuro-inflammation that triggers systemic inflammation. Because of the relationship between gastrointestinal microbiota and the central nervous system, it is important to learn how to promote health within the gut, which involves encouraging the growth of health-promoting bacteria and preventing the growth and presence of disease-promoting bacteria.

Polyphenols, which include the subcategory of flavonoids, have a beneficial impact on the microbiota. Anthocyanins , a subclass of flavonoids, can impact the diversity of bacteria present in the microbiota.

Part of the neuroprotective effects of anthocyanins is due to the high oxygen radical absorption capacity ORAC value. However, anthocyanins have a low absorption rate, and their metabolites produced in interaction with the microbiota are more bioavailable.

The most profound effects anthocyanins demonstrate are mobilized by the interaction within the microbiotic environment , where the polyphenolic compounds produce more bioavailable metabolites. Furthermore, the metabolites produced within the microbiota modulate the gut bacteria species present.

This change in microbial population impacts communication between the gut and the central nervous system. Anthocyanins may alter the macrobiotic environment to prevent the progression of age-related neurological disorders because the metabolites produced by anthocyanins support the growth of beneficial bacteria.

These beneficial bacteria promote communication between the gut and the brain through the enteric nervous system, giving anthocyanins additional neuromodulating effects that may prevent neurological and systemic inflammation.

Additionally, within the microbiota, anthocyanins are able to regulate the production of tryptophan related to serotonin production and short-chain fatty acids, as well as modulate the production of toxic lipopolysaccharides.

The complex and multidimensional biotransformation process that occurs metabolically with blue and purple foods make these plant compounds powerful neuroprotective agents with dynamic health-promoting and disease-preventing capabilities.

Anthocyanins have four routes of physiological effects:. Major sources of anthocyanins include blueberries, cherries, strawberries, raspberries, purple grapes, black currants, red cabbage, and red onion, in addition to the fruits and vegetables listed below.

Purple grapes and raisins, figs, boysenberries, and marionberries are other blue-purple fruits that can support brain health.

Anthocyanin biosynthesis Antuocyanins been aand extensively, and both biosynthetic and key regulatory genes have been isolated in many plant species. Here, we will provide an overview of recent progress in understanding the anthocyanin biosynthetic pathway in plants, focusing on the transcription factors controlling activation or repression of anthocyanin accumulation in cereals and fruits of different plant species, with special emphasis on the differences in molecular mechanisms between monocot and dicot plants. Recently, new insight into the transcriptional regulation of the anthocyanin biosynthesis, including positive and negative feedback control as well as epigenetic and post-translational regulation of MYB-bHLH-WD40 complexes, has been gained. Berries have the Anthoyanins to improve our mood as well as offer a Anthocywnins of health advantages. In addition to Anthocyanins and mood regulation delicious, Wellness programs are regualtion loaded with nutrients that Regular check-ups improve Ac percent conversion and general well-being. Here are regjlation scientific reasons why berries are considered mood-enhancing superfoods:. Berries, such as blueberries, strawberries, and blackberries, are rich in antioxidants like anthocyanins and flavonoids. These compounds have been shown to protect against oxidative stress and inflammation, both of which are linked to mood disorders like depression and anxiety. The antioxidants found in berries have been shown to have neuroprotective effects, meaning they can protect our brain cells from damage. This is important for maintaining good mental health, as brain health is closely linked to mood regulation.

Anthocyanins and mood regulation -

Of these 11 studies, flavanol intake was associated with improvements in global cognition as well as the cognitive domains of visual-spatial memory and organization, working memory, abstract reasoning, accuracy, reaction time, executive function, episodic memory, verbal fluency, and recognition memory.

There were no common methodological approaches amongst the studies reporting positive effects compared to those reporting no effect, with a wide range of age groups included, varying flavanol doses utilized and two studies incorporating the additional variables of sleep deprivation and exercise.

Orange juice is one of the most commonly consumed juices throughout the world and is a rich source of flavanones, particularly hesperidin and narirutin. As one of the most readily absorbed flavonoid subclasses, flavanones have been shown to cross the blood-brain barrier.

In other cognitive areas, the HF drink reduced the decline in performance associated with LF beverage consumption. Further, performance was better when the HF drink was consumed in the first arm of the trial than when the LF drink was consumed first, indicating effects of the HF drink may have continued into the second arm of the intervention Kean et al.

The effect of drinking a HF orange juice mg compared with placebo has been investigated acutely, with cognitive testing conducted at 2- and 6-h post-consumption, in a randomized, double-blind, counterbalance study, with a 2-week wash out period.

This study was conducted in 22 healthy males between 30 and 65 years of age. The HF drink contained Additionally, the change in performance from baseline to 6 h post-consumption on Continuous Performance Task accuracy, a measure of psychomotor speed, was significantly different across the treatments, with fewer errors observed when the HF drink had been consumed.

Lamport et al. The HF drink contained considerably less total flavanones than the previously mentioned studies, with Twenty-four young adults between 18 and 30 years of age underwent cognitive testing at baseline and 2 h post-drink consumption, and a further 16 participants underwent functional MRI assessment at baseline, 2- and 5-h post-drink consumption to measure cerebral blood flow CBF.

Regional perfusion in the inferior frontal gyrus and middle frontal gyrus of the right hemisphere was significantly higher 2 h post-consumption of the HF drink compared with the control drink. There were no differences in regional perfusion 5 h after consumption of either drink.

The inferior frontal gyrus has been implicated in tasks that require inhibition, planning, decision making, and other aspects of executive function, examined by the DSST. Stronger cognitive effects could have occurred more than 2 h post-drink consumption, as was seen in the previously mentioned studies, yet this was not assessed in the current study.

However, increased CBF was observed at 2 h and not 5 h post-consumption in the current study, suggesting that the time course by which flavonoids in orange and grapefruit juice exert their effect may differ from orange juice alone.

It is not possible, however, to determine a direct link between increased CBF and better cognitive function in the current study due to the separate cohorts utilized to investigate these outcomes. All three studies reviewed thus far in this section reported improvements in at least one cognitive domain following flavanone consumption one chronic study and two acute.

Global cognition as well as the cognitive domains of psychomotor speed, and executive function were positively impacted by flavanone consumption. All three studies also reported no associations of flavanone intake with episodic memory and verbal memory.

These three studies were conducted in cohorts of distinct age groups of cognitively normal adults, ranging from 30 to over 65 years. It appears therefore, that flavanone intake yields positive effects on cognition regardless of age.

Finally, a recent study assessed the association of long-term intake of total and six classes of dietary flavonoids flavanones, flavanols, flavonoid polymers, flavonols, flavones, and anthocyanins and decline in cognitive function, over a median follow-up period of up to The findings did not support a clear association, with nominally significant trends observed between 1 higher flavonol and flavanol intakes, and slower decline in global function, verbal and visual memory; 2 higher total flavonoid and flavonoid polymer intakes and slower decline in visual memory; and 3 slower decline in verbal learning with higher flavanol intake Shishtar et al.

The age range of participants, and sensitivity of cognitive measures used, may have impacted the study findings. Having a clear understanding of how these flavonoid subclasses are modulating cognitive function is required for furthering the use of these compounds as interventions which can be recommended by health professionals.

There is a relative paucity of data in humans, with the majority of mechanistic studies to date, having been undertaken in animal models. Nevertheless, these animal studies provide clues regarding potential mechanistic pathways in humans.

Collectively, the published studies implicate a number of candidate mechanisms underlying the beneficial effects of consumption of these flavonoid subclasses on cognitive function, including, modulation of intracellular signaling pathways, altered CBF, and conferring protection against neurotoxins and neuroinflammation.

The flavonoid subclasses of anthocyanins, flavanols, and flavanones modulate several neurological processes via their interaction with signaling pathways involved in neuronal survival and function, upregulation of proteins important for synaptic plasticity and neuronal repair, and inhibition of neuropathological processes which occur in brain regions typically implicated in AD pathogenesis.

Flavonoids have also been shown to modulate the cell death pathways mediated by p38 and c-Jun N-terminal kinase Hwang and Yen, to confer protection against neurodegeneration. These interactions are summarized in Figure 1.

Figure 1. Modulation of neuronal death and survival pathways by the flavonoid subclasses of anthocyanins, flavanols, and flavanones. Modified from Solanki et al. The activation of cell survival pathways by flavonoids involves upregulation of anti-apoptotic and pro-survival genes, and inhibition of pro-apoptotic proteins Levites et al.

Targets include inhibition of apoptosis signal-regulating kinase 1 ASK1; Vauzour et al. Flavonoids are also proposed to confer cell survival through activation of cAMP response element-binding protein CREBP phosphorylation Williams et al. As mentioned previously, BDNF is a neurotrophin required for the development and maintenance of the nervous system Schindowski et al.

BDNF levels are known to decline during aging, and their levels have been shown to correlate with learning and memory Garzon et al. JNK and p38 are strongly linked to transcription-dependent apoptotic signaling Mielke and Herdegen, via the activation of c-Jun and other activated protein 1 AP-1 proteins including Jun-B and Jun-D Behrens et al.

The inflammatory cascade is believed to play a critical role in the development of chronic low grade inflammatory diseases such as AD.

Reductions in blood levels of inflammatory markers such as CRP, IL-6, and tumor necrosis factor alpha TNF-α have been shown following flavonoid consumption, suggesting anti-inflammatory activity Carey et al.

Furthermore, flavonoids have the capacity to downregulate the activity of pro-inflammatory transcription factors such as NF-κB, nuclear factor erythroid 2-related factor 2 Nrf2 and STAT signal transducers and activators of transcription , through their influences on a number of glial and neuronal signaling pathways Hamalainen et al.

Mitochondria control cellular energy status, reactive oxygen species ROS production, and apoptosis, all of which are important for determining lifespan, and mitochondria are therefore, proposed to act as central organelles in the regulation of aging and neurodegeneration.

Mitochondria constitute the major source of superoxide and other ROS within most tissues. AMP-activated protein kinase AMPK , a key cellular regulator of energy metabolism, has been implicated in the regulation of mitochondria function.

Damaged mitochondria are the major sources of ROS in cells and are implicated in many neurodegenerative diseases including AD. Activated AMPK can decrease intracellular ROS by inhibiting NADPH nicotinamide adenine dinucleotide phosphate oxidase activity, or by increasing the expression of antioxidant enzymes such as superoxide dismutase-2 and uncoupling protein-2 Manczak et al.

Flavonoids may ameliorate mitochondrial dysfunction and increase oxidative defense mechanisms by activating AMPK Cordero-Herrera et al. Consumption of flavonoids could improve cerebrovascular outcomes including CBF. Whilst the mechanisms require elucidation, they may be related to increases in the pool of bioavailable nitric oxide NO; Bondonno et al.

One mechanism by which NO is synthesized is by the action of endothelial nitric oxide synthase eNOS on arginine, and flavonoids may enhance NO production by increasing eNOS activity or enhancing expression.

Decreases in blood pressure, improvements in endothelial function Bondonno et al. This is consistent with literature showing natural products that enhance brain metabolism or elevate CBF are effective at augmenting cognitive function during prolonged, effortful, cognitive processing Owen and Sunram-Lea, , with reduced blood flow to the brain associated with cognitive impairment Farkas et al.

Moreover, there is evidence to show that increasing glucoregulatory control via improved insulin sensitivity can improve cognitive function, with intake of flavonoids being shown to increase insulin sensitivity, as well as insulin and glucose levels Russo et al.

Attenuation of decline in blood glucose concentrations has been observed following blackcurrant Watson et al. Evidence accumulated to date suggests the consumption of products containing anthocyanins, flavanols, and flavanones, such as berries and cocoa, throughout life, may have the potential to limit or even reverse age-related declines in cognition and memory, and potentially delay the onset and progression of neurodegenerative diseases such as AD.

Over the last 6 years, the flavonoid subgroups of anthocyanins, flavanols, and flavanones have been shown to be beneficial in terms of conferring neuroprotection and cognitive benefit.

Of note, however, methodological disparities hinder comparison of results between studies. For example, a vast range of flavonoid-containing products utilized in interventions of varying durations, and differences in comprehensiveness of neuropsychological assessments, as well as heterogeneity of cohorts, are all likely to impact findings.

Of the literature reviewed here, acute studies ranged in duration from 60 min to 6 h, whilst the longer-term studies ranged from 28 days to 6 months, with 3 months being the most common timeframe employed.

All except two intervention studies included control groups consuming a placebo, with these two studies comparing cognitive function at baseline to end point 16 weeks or 6 h. Whilst studies were included in the current review regardless of placebo being matched with the intervention condition for macro- and micro- nutrient content, this should be a consideration when designing future interventions, to ensure observed effects are due to the flavonoid content and not additional components e.

The quantity of flavonoid treatment in the reviewed studies also varied greatly, with some participants consuming mg daily or greater, and others under mg.

Interestingly, a study including groups of participants consuming mg or mg daily, for 8 weeks, found both quantities were associated with improvements in measures of attention, visual search and scanning, sequencing and shifting, and psychomotor speed, but only the mg group also demonstrated increased performance in verbal fluency Mastroiacovo et al.

A range of cognitive domains have been shown to be beneficially affected in the reviewed studies; summarized in Figure 2. Acute supplementation with the three flavonoid subclasses investigated was associated with positive effects in tests measuring psychomotor speed, executive function, and attention.

Longer-term supplementation was associated with positive effects in tests of episodic memory, global cognition, verbal fluency, psychomotor speed, and verbal memory, in multiple studies.

Although a particular task may have a primary focus such as verbal fluency or episodic memory, a range of processes may support the primary focus, e. Potentially, flavonoids could be exerting greater effects on relatively effortful tasks and less effect on simpler tasks. This notion is consistent with the results of Bondonno et al.

Furthermore, Gratton et al. A wide range of tasks which fully assess cognitive ability multiple domains and tasks of varying complexity needs to be employed by studies attempting to fully characterize the effects of flavonoids on cognition.

Figure 2. Cognitive domains affected by the flavonoid subclasses of anthocyanins, flavanols, and flavanones. The mechanisms by which the flavonoid subclasses of anthocyanins, flavanols, and flavanones modulate cognitive function are yet to be fully established.

Available evidence plausibly suggests these flavonoid subclasses can promote beneficial effects via both direct i. Although, it should be noted that the majority of mechanistic studies to date have been conducted in animal models, and more human studies are required to draw definitive conclusions.

Wide inter-individual variability in flavonoid absorption and metabolism has been reported, with a number of factors including age and gender affecting these metabolic processes. Flavonoids initially undergo extensive metabolization by phase I and II metabolism which occur predominantly in the gastrointestinal tract and liver.

Hepatic perfusion and morphology reduce as part of the aging process, which has been suggested to reduce phase I and II metabolism of flavonoids.

Flavonoid absorption occurs in both the small and large intestines, with a high percentage reaching the colon where there is exposure to colonic microbiota Williamson and Clifford, The microbiome plays a key role in catabolizing unabsorbed flavonoids into smaller molecules which may become bioavailable.

It is conceivable that heterogeneity in flavonoid absorption and metabolism may diminish beneficial associations between intakes and cognitive outcomes reported in studies. Ideally, urinary flavonoid excretion results would be taken into account in analyses, and to inform personalized health goals.

Overall, additional prospective studies conducted in diverse populations, and adequately powered intervention studies with long durations, are required to thoroughly examine the effect of consumption of the flavonoid subclasses of anthocyanins, flavanols, and flavanones on clinically relevant cognitive outcomes.

Moreover, the characterization of appropriate dosage, timeframes for intake, and form of flavonoids, remains to be fully determined. Whilst animal models have shown promising results with interventions of timeframes such as 2 months, this represents a considerably larger percentage of total lifespan for animals than it does for humans, and a longer time-frame could be needed to show enhanced outcomes in human trials.

Both acute and chronic effects of these flavonoid subclasses also need to be investigated using neuroimaging techniques in conjunction with cognitive and physiological measures to further elucidate the underlying biological mechanisms.

Furthermore, it should be acknowledged that studies in cognitively normal adults are unlikely to demonstrate large improvements in cognitive function, and therefore it is imperative that suitable, sensitive cognitive tests are utilized. There is currently no clear evidence regarding the specific domains of cognition and memory that these flavonoid subclasses impact, with future studies requiring a range of cognitive domains to be investigated in order to determine those most likely to benefit.

If emerging evidence continues to suggest significant cognitive benefit, another important consideration is the optimum age for the initiation of supplementation of flavonoid intake. Indeed, the neuropathological hallmarks of AD begin to accumulate 15—20 years before symptoms manifest, implying that the optimal age for supplementing flavonoid consumption could be middle-age or younger.

As populations continue to focus on developing strategies to promote healthy aging, dietary interventions with flavonoids represents a promising avenue for future research.

However, many questions still need to be answered before a definite conclusion can be made regarding the extent to which consumption of anthocyanins, flavanols, and flavanones can protect the aging brain, and intake can be included in public health dietary recommendations.

Diabetes, 60 9 , Leptin plays a significant role among these neuron cells. The main hormone related to satiety is leptin. Leptin is synthesized and secreted mainly by fat cells called adipocytes of the white adipose tissue. Its main function is regulating energy balance.
