Can casual turn into a relationship Exp Med 1 February ; 2 : e Recent and accumulating work in experimental animal models and humans shows that diet has a much more pervasive and prominent role than previously thought in modulating neuroinflammatory and neurodegenerative mechanisms leading foods that prevent alzheimers and dementia some of the most common chronic central nervous system CNS diseases.

Chronic or intermittent food restriction has profound effects in shaping brain and peripheral metabolism, immunity, and gut microbiome biology. This review discusses these findings and their potential application to the prevention and treatment of CNS neuroinflammatory diseases and the promotion of healthy brain aging. Dietary restriction DR is defined as a chronic or intermittent reduction of food intake without malnutrition.

It is the most robust experimental intervention to delay the onset of a wide range of age-associated pathologies and to extend lifespan, as shown in a variety of species Foods that prevent alzheimers and dementia and Partridge, Evidence from experimental studies indicates that age-associated accumulation of molecular and cellular damage can be prevented or greatly delayed by dietary, genetic, and pharmacological manipulations that down-regulate key cellular nutrient-sensing and inflammatory pathways Fontana et al.

Health-promoting actions of DR include metabolic, antioxidant, and immunomodulatory adaptations that could potentially influence the initiation, progression, and prognosis of a range of neurological and neuroinflammatory disorders. Neuroinflammation is a coordinated response of the central nervous system CNS to harmful stimuli and injuries, including those occurring during infections, traumatic brain injury, or other neurological diseases.

It is characterized by activation and proliferation of the two major CNS glial cells, microglia and astrocytes, which undergo morphological changes and release proinflammatory mediators cytokines, chemokines, and complement proteins; Matias et al. Often, neuroinflammation is associated with increased blood—brain barrier permeability, allowing immune cell trafficking and soluble proinflammatory factors to enter the CNS, where they can directly interact with glial and neuronal cells and contribute to the inflammatory process.

The goal of inflammatory and immune responses is to clear the hazard. When this is achieved, activation of anti-inflammatory pathways then offsets the inflammatory process to restore tissue integrity and function. If the precipitating factors are persistent as in some neurodegenerative diseaseschronic neuroinflammation may ensue. Foods that prevent alzheimers and dementia neuroinflammation has been proposed as a potential deleterious mediator of aging, as well as other pathological conditions Di Benedetto et al.

Recent advances are highlighting the complex relationship between nutrient metabolism and the activation of inflammatory pathways in different tissues including the brain. Notably, disruption of brain energy metabolism with reduced glucose consumption, increased central insulin resistance, and impaired mitochondrial function have been linked to the mechanisms leading to neuroinflammatory and age-related neurodegenerative diseases Cunnane et al.

This evidence prompted the hypothesis that reestablishing metabolic balance could be a key intervention to counteract underlying disease processes. DR could potentially serve this purpose by exerting its effects on metabolic and anti-inflammatory pathways. This review foods that prevent alzheimers and dementia aims to summarize current evidence regarding the effects of DR on neuroinflammation and the potential central and systemic underlying mechanisms.

Major studies that tested the effects of DR in experimental models, epidemiological studies, and clinical trials for various neurodegenerative disorders in which neuroinflammation may play a role are discussed. DR can be achieved by chronically reducing food intake or by changing meal frequency and timing Fig. In contrast, with intermittent fasting IFfood intake is completely eliminated or greatly reduced intermittently, for example, every other day.

IF in experimental models usually refers to every-other-day h complete fasting, while in humans it refers to a variety of approaches including fasting or calorie restriction e. Another form of intermittent DR is time-restricted feeding, which involves consuming all daily food in a 4- to 6-h time window and fasting for the remainder of the day Cienfuegos et al.

Evidence from clinical and animal studies suggests that chronic DR and Foods that prevent alzheimers and dementia affect lifespan and age-associated diseases via similar metabolic and molecular mechanisms Hadem et al. Central and systemic effector mechanisms contribute to CNS neuroinflammation. Central mechanisms are driven by primary CNS insults e. CNS inflammation can also be induced or potentiated by peripheral factors such as systemic inflammatory mediators reaching the CNS, insulin resistance, and other metabolic conditions e.

Environmental factors e. Recent advances have recognized a prominent role in the connections between the periphery and the brain of the gut—brain axis, which is the bidirectional communication between the central and the enteric nervous systems linking gut functions with emotional and cognitive centers in the brain. A primary role in this complex cross-talk is played by the gut microbiota through neural, endocrine, immune, and humoral mechanisms partially mediated by the vagus nerve and the parasympathetic nervous system Fig.

In this scenario, DR elicits protective changes in the gut microbiota what is normal communication, with metabolic and molecular adaptations in nearly all tissues and organs including the brain. Thus, DR can potentially modulate both central and peripheral factors contributing to neuroinflammation.

The main adaptations induced by DR on metabolic and neuroinflammatory pathways are discussed in this section and summarized in Fig. DR powerfully reduces adiposity, especially visceral adiposity Das et al. In experimental models, DR reduces the proinflammatory adipokine leptin and increases adiponectin, which has insulin-sensitizing and anti-inflammatory effects Higami et what to write in a dating site profile. In humans, DR induces similar changes in serum adipokines Fontana et al.

Mechanistically, adipokines are important nodes integrating immunometabolic pathways and controlling T cell effector functions. Chronic DR in rodents and humans improves insulin sensitivity and glucose tolerance Kraus et al. RAGE activation elicits up-regulation of proinflammatory cytokines e. In rodents, chronic DR and IF have foods that prevent alzheimers and dementia consistently associated with foods that prevent alzheimers and dementia circulating levels of endogenous corticosteroids, hormones with potent anti-inflammatory and immunomodulatory activities.

As in animals, long-term DR in humans is associated with sustained rises in serum foods that prevent alzheimers and dementia Fontana et al. Furthermore, DR foods that prevent alzheimers and dementia associated with a significant increase in key stress-related molecular chaperones HSP and Grp78 and autophagic LC3 and beclin-1 mediators involved in cellular protein quality control foods that prevent alzheimers and dementia removal of dysfunctional proteins and organelles Yang et al.

Another mechanism through which DR may inhibit inflammation is by reducing the accumulation of senescent cells during aging Fontana et al. Cellular senescence is a potent tumor-suppressive mechanism that inhibits the proliferation of cells at risk for malignant transformation, but at the same time induces the secretion of a range of can i look on tinder without signing up factors, metalloproteinases, proinflammatory cytokines, and chemokines, collectively named SASPs Chinta et al.

Cell senescence can be prematurely induced by several insults, including cellular damage caused by metabolic dysfunction, oxidative stress, genotoxic stress, and overactivation of oncogenes or loss of some tumor suppressor genes Borghesan et al. Accumulating evidence suggests that the chronic inflammatory SASP environment contributes to brain aging and to the development of age-associated diseases, including AD Ovadya and Krizhanovsky, Recent studies have linked tau-dependent pathology to cellular senescence and failure to clear senescent glial cells Bussian et al.

Astrocytes help to maintain glutamate homeostasis in the brain by removing extracellular glutamate via excitatory amino acid transporters. Astrocyte senescence may foods that prevent alzheimers and dementia glutamate toxicity in cortical foods that prevent alzheimers and dementia, which causes and enhances neurodegeneration and neuroinflammation Limbad et al.

Several DR animal studies as well as long-term DR in humans have shown that DR was associated with reduced senescent cell markers in multiple tissues Fontana et al. The autonomic nervous system regulates important body functions such as heart rate, blood pressure, and gastrointestinal motility, but it also modulates systemic filth definition in spanish Pavlov and Tracey, ; Salama et al.

Rodent studies have shown that DR increases the high-frequency component of the heart rate variability spectrum, a marker of parasympathetic activity Mager et al. Similarly, long-term DR without malnutrition in humans increased parasympathetic activity as measured by heart rate variability Stein et al. Another mechanism through which DR may induce beneficial metabolic and anti-inflammatory effects involves alterations of gut microbiota composition and function Estrada and Contreras, The gut microbiota plays a crucial role in maintaining a symbiotic relationship with the host and regulates several important functions, including host metabolism and intestinal and systemic immune inflammatory responses Rooks and Garrett, Life-long DR in mice is known to change the gut microbiota structure with enrichment of anti-inflammatory bacteria strains such as the genus Lactobacillus, accompanied by reduced serum proinflammatory endotoxin load from the gut Zhang et al.

In a different study in naive mice, every-other-day fasting altered the gut microbiota composition by increasing levels of Firmicutes and the production of short-chain fatty acids, which are known to have immunomodulatory and anti-inflammatory effects Li et al. We showed that 1 mo of IF led to increased gut bacteria diversity, with enrichment of the Lactobacillaceae, Bacteroidaceae, and Prevotellaceae families and associated enhancement of several antioxidative microbial metabolic pathways.

These changes were associated with increased frequencies of gut-associated regulatory T cells and decrease of IL—producing T cells Foods that prevent alzheimers and dementia Cignarella et al. In humans, long-term DR was shown to increase gut microbiota richness and diversity, characteristics referring to the number of bacterial species based on total bacterial gene counts in the gut and of individual bacteria within each species, respectively. High microbiota richness is associated with improved metabolic health reduced adiposity; lower leptin, insulin, and triglycerides; and higher adiponectin and HDL cholesterol levels and reduced inflammation lower C-reactive protein and white blood cell counts; Le Chatelier et al.

One study showed that the gut microbiota of individuals practicing chronic DR were significantly more diverse when compared with individuals on a typical Western diet Griffin et al. Numerous studies have explored DR effects in normal brain aging as well as chronic neuroinflammatory and neurodegenerative diseases. Most of the long-term studies were conducted in rodents and monkeys.

Human studies have mainly been relatively short-term trials testing the effects of the diet primarily on systemic metabolic conditions. In the following section, we review the main published studies on the effects of DR on normal aging and neurodegenerative diseases summarized in Table 1 in which systemic and brain inflammation plays a prominent role. Neuroinflammation accompanies the age-related decline of brain function Di Benedetto et al.

Acquisition of a senescent phenotype by microglia may also contribute to the development of foods that prevent alzheimers and dementia neurodegenerative diseases Streit, ; Wong, Several lines of evidence foods that prevent alzheimers and dementia shown that DR exerts beneficial effects against age-driven neuroinflammation. In rodents, DR attenuated age-dependent astrocyte and microglia activation foods that prevent alzheimers and dementia the brain Kaur et al.

Similarly, short-term IF ameliorated age-associated decrease in motor and cognitive performance in rats by enhancing mitochondrial complex IV activity and reducing oxidative molecular damage Singh et al. The effects of DR on brain aging in rodents are discussed in more detail in a recent review by Hadem et al. Data on DR effects on neuroinflammation in nonhuman primates are accumulating. Most published reports have examined DR neuroprotective effects on neuroimaging biomarkers or brain pathology.

Moreover, chronic DR in nonhuman primates improved insulin sensitivity and lowered blood proinflammatory cytokine concentrations, which were associated with more gray matter volume in the hippocampus and more white matter volume primarily in visual areas and the dorsal prefrontal cortex Willette et al. Chronic metabolic disorders e. Cognitive performance of metabolically morbid individuals is poorer than their age-matched healthy counterparts Kullmann et foods that prevent alzheimers and dementia.

Several epidemiological studies have reported that obesity and metabolic syndrome in midlife are associated with impaired cognitive function Debette et al. A population-based cohort study of cognitively healthy participants suggested that high visceral adiposity and foods that prevent alzheimers and dementia inflammation were associated with deep white matter brain hyperintensities, reduced gray matter volume measured by MRIand potentially with reduced executive functions Lampe et al.

In humans, studies of chronic DR have reported beneficial effects on metabolic factors and cognitive functioning in healthy volunteers and obese and hypertensive patients. These pathological hallmarks are also observed in normal brain aging, but in AD they progress much faster and to a greater extent. Systemic inflammation and insulin resistance are emerging as important drivers of AD progression Heneka et al. Several studies have demonstrated beneficial effects of DR or IF on brain pathology and functional outcomes in AD transgenic rodent models Table 1.

In triple-transgenic mouse models of AD, an IF regimen has been associated with increased neuronal differentiation in the hippocampus Li et al. A comprehensive review of these studies has been recently published Bok et al. Epidemiological data suggest a relationship between calorie intake, obesity, and dementia risk. A prospective study of a large cohort of elderly individuals free of dementia at baseline provided evidence that those with a lower calorie intake had a reduced risk of developing AD Luchsinger et al.

Obesity at midlife increases the risk of AD, as shown in a population-based cohort study with an average yr follow-up. In this study, clustering of vascular risk factors high total cholesterol and high blood pressure increased the risk in an additive manner Kivipelto et al. Other epidemiological studies suggest a strong association between high blood pressure and late-life dementia Ding et al.

In an yr follow-up study of nondemented women, being overweight at age 70 was associated with a higher risk of developing dementia later in life; for every 1. Preliminary data from randomized controlled trials are supportive of a cause—effect relationship. In this study, improvements in insulin resistance and inflammation were associated with what does it mean when an equation is linear cognitive tests.

More randomized trials on the effects of DR in individuals with subjective memory complaints and MCI are currently ongoing.
