Interactions between immune systems, nervous systems, and behavior are well established in vertebrates. A comparative examination of these interactions in other animals will help us understand their evolution and present adaptive functions. Insects show immune-behavioral interactions similar to those seen in vertebrates, suggesting that many of them may have a highly conserved function. Activation of an immune response in insects results in illness-induced anorexia, behavioral fever, changes in reproductive behavior, and decreased learning ability in a broad range of species. Flight-or-fight behaviors result in a decline in disease resistance. In insects, illness-induced anorexia may enhance immunity. Stress-induced immunosuppression is probably due to physiological conflicts between the immune response and those of other physiological processes. Because insects occupy a wide range of ec…

Sakurai T (2006)reviewMEDLINE-indexed journal, not yet read by usCNS & neurological disorders drug targets58 citations Roles of orexins and orexin receptors in central regulation of feeding behavior and energy homeostasis.
Orexins were initially recognized as regulators of feeding behavior due to their exclusively production in the lateral hypothalamic area (LHA), a feeding center. Subsequently, the finding that orexin deficiency causes narcolepsy in humans and animals suggested that these hypothalamic neuropeptides play a critical role in regulating and maintaining sleep/wakefulness states. Proper maintenance of arousal during food searching and intake is essential for an animal's survival. Therefore, feeding behavior and sleep/wakefulness states are appropriately coordinated. For example, when faced with reduced food availability, animals adapt with a longer wakefulness period, which disrupts the normal circadian pattern of activity. The discovery that orexin neurons are regulated by peripheral metabolic cues, including ghrelin, leptin and glucose, suggests that they might have important roles as a link …

Polyphenols and Their Impact on the Prevention of Neurodegenerative Diseases and Development.
It is well known that neurodegenerative diseases' development and progression are accelerated due to oxidative stress and inflammation, which result in impairment of mitochondrial function, cellular damage, and dysfunction of DNA repair systems. The increased consumption of antioxidants can postpone the development of these disorders and improve the quality of patients' lives who have already been diagnosed with neurodegenerative diseases. Prolonging life span in developed countries contributes to an increase in the incidence ratio of chronic age-related neurodegenerative disorders, such as PD (Parkinson's disease), AD (Alzheimer's disease), or numerous forms of age-related dementias. Dietary supplementation with neuroprotective plant-derived polyphenols might be considered an important element of healthy aging. Some polyphenols improve cognition, mood, visual functions, language, and ve…

Nutrition and mental health: A review of current knowledge about the impact of diet on mental health.
Applied psychopharmacotherapy and psychotherapy do not always bring the expected results in the treatment of mental disorders. As a result, other interventions are receiving increasing attention. In recent years, there has been a surge in research on the effects of nutrition on mental status, which may be an important aspect of the prevention of many mental disorders and, at the same time, may lead to a reduction in the proportion of people with mental disorders. This review aims to answer whether and to what extent lifestyle and related nutrition affect mental health and whether there is scientific evidence supporting a link between diet and mental health. A review of the scientific evidence was conducted based on the available literature by typing in phrases related to nutrition and mental health using the methodological tool of the PubMed database. The literature search yielded 3,473 …

Correlates of English local government use of the planning system to regulate hot food takeaway outlets: a cross-sectional analysis.
Background: Greater neighbourhood takeaway food outlet access has been associated with increased takeaway food consumption and higher body weight. National planning guidelines in England suggest that urban planning could promote healthier food environments through takeaway food outlet regulation, for example by restricting the proliferation of outlets near schools. It is unknown how geographically widespread this approach is, or local characteristics associated with its use. We aimed to address these knowledge gaps.
Methods: We used data from a complete review of planning policy documents adopted by local government areas in England (n = 325), which contained policies for the purpose of takeaway food outlet regulation. This review classified local government area planning policies as having a health (diet or obesity) or non-health focus. We explored geographical clustering of similar pla…

The Role of Nutrition and the Gut-Brain Axis in Psychiatry: A Review of the Literature.
Introduction: Individuals suffering from psychiatric disorders experience high levels of illness burden and a significantly reduced quality of life. Despite targeted psychopharmacological strategies and complementary psychotherapeutic procedures only moderate effects are obtained, and the risk of relapse is high in many patients. Worldwide, psychiatric diseases such as depression are continuously increasing, challenging the personal life of the affected as well as their families, but also whole societies by increasing disability, early retirement and hospitalization. According to current scientific knowledge psychiatric disorders are caused by a multifactorial pathogenesis, including genetics, inflammation and neurotransmitter imbalance; furthermore, also lifestyle-associated factors gain rising importance. In line with this, there is growing evidence that the gut microbiota and nutritio…

Exploring the Association between Alzheimer's Disease, Oral Health, Microbial Endocrinology and Nutrition.
Longitudinal monitoring of patients suggests a causal link between chronic periodontitis and the development of Alzheimer's disease (AD). However, the explanation of how periodontitis can lead to dementia remains unclear. A working hypothesis links extrinsic inflammation as a secondary cause of AD. This hypothesis suggests a compromised oral hygiene leads to a dysbiotic oral microbiome whereby Porphyromonas gingivalis, a keystone periodontal pathogen, with its companion species, orchestrates immune subversion in the host. Brushing and chewing on teeth supported by already injured soft tissues leads to bacteremias. As a result, a persistent systemic inflammatory response develops to periodontal pathogens. The pathogens, and the host's inflammatory response, subsequently lead to the initiation and progression of multiple metabolic and inflammatory co-morbidities, including AD. Insufficient…

Zou P (2016)reviewMEDLINE-indexed journal, not yet read by usThe American journal of Chinese medicine51 citations Traditional Chinese Medicine, Food Therapy, and Hypertension Control: A Narrative Review of Chinese Literature.
Despite the lack of English literature about Traditional Chinese Medicine (TCM) food therapy, there is abundant Chinese literature about the application of food therapy for hypertension control. This paper summarizes basic concepts of TCM, the principles of food therapy and its application for hypertension control according to Chinese literature. In TCM, food is conceptualized according to both nutritional and functional aspects, and can be used to treat illnesses. Four principles of TCM food therapy including light eating, balancing the "hot" and "cold" nature of food, the harmony of the five flavors of food, and consistency between dietary intake and different health conditions, can be used to facilitate hypertension control. Based on a statistical analysis of antihypertensive foods recommended in 20 books on the application of food therapy for hypertension control, the 38 most frequen…

Diet-Induced Cognitive Deficits: The Role of Fat and Sugar, Potential Mechanisms and Nutritional Interventions.
It is of vital importance to understand how the foods which are making us fat also act to impair cognition. In this review, we compare the effects of acute and chronic exposure to high-energy diets on cognition and examine the relative contributions of fat (saturated and polyunsaturated) and sugar to these deficits. Hippocampal-dependent memory appears to be particularly vulnerable to the effects of high-energy diets and these deficits can occur rapidly and prior to weight gain. More chronic diet exposure seems necessary however to impair other sorts of memory. Many potential mechanisms have been proposed to underlie diet-induced cognitive decline and we will focus on inflammation and the neurotrophic factor, brain-derived neurotrophic factor (BDNF). Finally, given supplementation of diets with omega-3 and curcumin has been shown to have positive effects on cognitive function in healthy …

Prevention of type 2 diabetes mellitus: is it feasible?
The increasing global prevalence of type 2 diabetes mellitus (T2DM) requires the implementation of preventive strategies to halt this trend, tailored to the specific needs of individual regions. Risk factors for T2DM are among the main targets for improving health outcomes and curbing the development of diabetes; excessive weight and obesity are two of the most important risk factors that need to be addressed. A growing body of evidence suggests that subjects with pre-diabetes who lose body weight and increase physical activity can delay or prevent the onset of T2DM, and in some cases, blood glucose levels may return to normal. Several studies have shown that moderate to intensive levels of exercise are effective in reducing both intra-abdominal and total adiposity among obese subjects, both improving cardiovascular risk profile and reducing the risk of T2DM development. These consistent…

Longitudinal diet quality is not associated with depressive symptoms in a cohort of middle-aged Australian women.
There is increasing evidence for the role of nutrition in the prevention of depression. This study aims to describe changes in diet quality over 12 years among participants in the Australian Longitudinal Study on Women's Health in relation to changes in depressive symptoms. Women born between 1946 and 1951 were followed-up for 12 years (2001-2013). Dietary intake was assessed using the Dietary Questionnaire for Epidemiological Studies (version 2) in 2001, 2007 and every 2-3 years after that until 2013. Diet quality was summarised using the Australian Recommended Food Score (ARFS). Depressive symptoms were measured using the ten-item Centre for Epidemiologic Depression Scale at every 2-3-year intervals during 2001-2013. Linear mixed models were used to examine trends in diet quality and its sub-components. The same model including time-varying covariates was used to examine associations b…

Background: Meat intake may be related to weight gain because of its high energy and fat content. Some observational studies have shown that meat consumption is positively associated with weight gain, but intervention studies have shown mixed results.
Objective: Our objective was to assess the association between consumption of total meat, red meat, poultry, and processed meat and weight gain after 5 y of follow-up, on average, in the large European population who participated in the European Prospective Investigation into Cancer and Nutrition-Physical Activity, Nutrition, Alcohol, Cessation of Smoking, Eating Out of Home and Obesity (EPIC-PANACEA) project.
Design: A total of 103,455 men and 270,348 women aged 25-70 y were recruited between 1992 and 2000 in 10 European countries. Diet was assessed at baseline with the use of country-specific validated questionnaires. A dietary calibratio…

Dietary patterns: a Mediterranean diet score and its relation to clinical and biological markers of cardiovascular disease risk.
Background and aim: It has been suggested that overall dietary patterns and not single nutrients should be studied, since food items might have a synergistic and antagonistic effect on health. The Mediterranean diet has long been associated with lower incidence of cardiovascular disease and cancer. Therefore, we developed a diet score that incorporates the inherent characteristics of this dietary pattern.
Methods and results: We used 11 main components of the Mediterranean diet (non-refined cereals, fruits, vegetables, potatoes, legumes, olive oil, fish, red meat, poultry, full fat dairy products and alcohol). For the consumption of items presumed to be close to this pattern we assigned scores 0, 1, 2, 3, 4 and 5 when a participant reported no consumption, rare, frequent, very frequent, weekly and daily, respectively. For the consumption of foods presumed to be away from this pattern we …

Mediterranean diet and depression: reanalysis of a meta-analysis.
On the basis of comments we received from readers, we made some changes in the original version of our article about our study and re-analyzed the data. In this corrected version, we found an inverse significant association between adherence to the Mediterranean diet and risk of depression in cohort studies (overall hazard ratio, 0.81; 95% confidence interval, 0.70-0.94). In addition, combining 8 cross-sectional studies that examined the association between adherence to the Mediterranean diet and depression, we found a significant inverse association (overall odds ratio, 0.81; 95% confidence interval, 0.71-0.92).

Sam-Yellowe TY (2024)reviewMEDLINE-indexed journal, not yet read by usFoods (Basel, Switzerland)18 citations Nutritional Barriers to the Adherence to the Mediterranean Diet in Non-Mediterranean Populations.
Adherence to the Mediterranean diet has been shown to lower the risk of developing chronic non-communicable diseases like cardiovascular and neurodegenerative diseases and cancer. Improvements in depression, participation in daily activities in older individuals, weight loss and a reduction in adverse pregnancy outcomes are associated with adherence to the Mediterranean diet. The number of studies that have evaluated barriers to adherence to the Mediterranean diet in the US and, in particular, in racial and ethnic minority populations within the US are few. Among Native American and Alaskan Native populations, studies evaluating traditional or alternative Mediterranean diet adherence for chronic non-infectious diseases is unavailable. Mediterranean diet scoring instruments used in studies in European and Mediterranean countries and among white participants in the US fail to capture the d…

Overview and prospect of NAFLD: Significant roles of nutrients and dietary patterns in its progression or prevention.
NAFLD is the most common chronic liver disease worldwide, characterized by lipid accumulation in the liver, and usually evolves from steatohepatitis to fibrosis, cirrhosis, or even HCC. Its incidence is rapidly rising in parallel with the increasing prevalence of obesity and metabolic syndrome. Current therapies are limited to lifestyle changes including dietary intervention and exercise, in which dietary modification exerts an important part in losing weight and preventing NAFLD. In this review, we briefly discuss the roles and mechanisms of dietary components including fructose, non-nutritive sweeteners, fat, proteins, and vitamins in the progression or prevention of NAFLD. We also summarize several popular dietary patterns such as calorie-restricted diets, intermittent fasting, ketogenic diets, Mediterranean diets, and dietary approach to stop hypertension diets and compare the effect…

Fad Diets: Facts and Fiction.
The global prevalence of obesity is alarmingly high and is impacting both developed and underdeveloped countries, beyond the borders of ethnicity, sex, and age. On the other hand, the global interest in dieting has increased, and people are obsessed with certain fad diets, assuming them as a magic bullet for their long-term problems. A fad diet is a popular dietary pattern known to be a quick fix for obesity. These diets are quite appealing due to the proposed claims, but the lack of scientific evidence is a big question mark. Such diets are often marketed with specific claims that defy the basic principles of biochemistry and nutritional adequacy. These diets may have protective effects against obesity and certain chronic diseases like cardiovascular diseases, metabolic syndrome, and certain cancers. Limited evidence exists to support the proposed claims; rather certain studies suggest …

Healthy diet, depression and quality of life: A narrative review of biological mechanisms and primary prevention opportunities.
Unipolar depressive disorder (UDD) affects more than 264 million people worldwide and was projected well before the severe acute respiratory syndrome coronavirus 2 pandemic to be the leading cause of disability-adjusted life years lost in 2030. It is imperative for leading economies to implement preventive strategies targeted towards UDD, given consistent policies are currently lacking. Recently established similarities between the aetiological hypotheses of depression and cardiometabolic diseases are shifting paradigms within this field. It is believed that dietary practices could potentially reduce the incidence of depression; similar to their effects on metabolism. Thus, the aim of this review was to compile current evidence on healthy dietary patterns as suitable contributors towards primary prevention strategies against UDD. Most of the well-known biological mechanisms behind depres…

Linking What We Eat to Our Mood: A Review of Diet, Dietary Antioxidants, and Depression.
Studies have shown that diet and nutrition play significant roles in the prevention of depression and its clinical treatment. The present review aims to provide a clear understanding of the associations between diet patterns, specific foods, nutrients such as antioxidants, and depression. As a result, balanced dietary patterns such as the Mediterranean diet and certain foods such as fish, fresh vegetables, and fruits have been associated with a lower risk of depression or depressive symptoms, while high-fat Western diets and sugar-sweetened beverages have been associated with higher risk of depression or depressive symptoms. Dietary antioxidants such as green tea polyphenols or isoflavonoid intake have been negatively associated with depression or depressive symptoms. It is concluded that diet patterns, specific foods, and antioxidants play important roles in the prevention and clinical …

Adolescent Undernutrition: Global Burden, Physiology, and Nutritional Risks.
Background: Adolescents, comprised of 10-19 year olds, form the largest generation of young people in our history. There are an estimated 1.8 billion adolescents in the world, with 90% residing in low- and middle-income countries. The burden of disease among adolescents has its origins in infectious and injury-related causes, but nutritional deficiencies, suboptimal linear growth, and undernutrition are major public health problems, even as overweight may be on the rise in many contexts. Summary and Key Messages: Girls are most vulnerable to the influences of cultural and gender norms, which often discriminate against them. Dietary patterns and physical activity, in addition to schooling and countervailing social norms for early marriage, influence health and nutritional well-being of adolescents. Nutrient requirements - -including those for energy, protein, iron, calcium, and -others - …

Background and aims: The Mediterranean Diet (MD) is characterized by a high intake of vegetables, fruit, legumes, nuts, and olive oil, and moderate fish, dairy, and wine intake. A high adherence to MD has been associated with numerous health benefits, including reduced risk of chronic diseases such as cardiovascular disease, cancer, and type 2 diabetes. The clinical assessment of MD adherence is complicated by the absence of a univocally accepted tool and by the abundance of questionnaires developed to determine adherence, whose reliability and validity is uncertain. In this inter-associative document, we critically evaluated servings-based questionnaires for the assessment of MD adherence, aiming to identify the most valuable tool for the use in clinical practice.
Methods and results: For each questionnaire, we analyzed the structure, evidence on health-related outcomes and agreement wi…

The Association between Salt Taste Perception, Mediterranean Diet and Metabolic Syndrome: A Cross-Sectional Study.
Metabolic syndrome (MetS) is a widespread disorder and an important public health challenge. The purpose of this study was to identify the association between salt taste perception, Mediterranean diet and MetS. This cross-sectional study included 2798 subjects from the general population of Dalmatia, Croatia. MetS was determined using the Joint Interim Statement definition, and Mediterranean diet compliance was estimated using Mediterranean Diet Serving Score. Salt taste perception was assessed by threshold and suprathreshold testing (intensity and hedonic perception). Logistic regression was used in the analysis, adjusting for important confounding factors. As many as 44% of subjects had MetS, with elevated waist circumference as the most common component (77%). Higher salt taste sensitivity (lower threshold) was associated with several positive outcomes: lower odds of MetS (OR = 0.69; …
