A review of the impact of social disruptions on food security and food choice.

At times of severe social disruption, be that war, conflict, pandemic, or economic downturn, both the availability and consumption of healthy dietary patterns can be adversely affected with any effects often outlasting the initial social disruption. For instance, when the COVID-19 pandemic hit and lockdown restrictions followed, households were reported to consume unhealthy diets. In some cases, this seemed to be a response to the situation and a coping mechanism.

Effectiveness of lifestyle interventions/culturally bespoke programmes in South Asian ethnic groups targeting weight loss for prevention and/or remission of type 2 diabetes: a systematic review and meta-analysis of intervention trials.

Background: People from South Asian heritage are at high risk of type 2 diabetes, but there are limited specific strategies to prevent and manage this condition. The aim was to assess the effectiveness of culturally bespoke lifestyle programmes in South Asians that target weight loss for the prevention or remission of type 2 diabetes mellitus (T2DM).

Methods: We performed a systematic review and meta-analysis of intervention trials.

Does a Ketogenic Diet Have a Place Within Diabetes Clinical Practice? Review of Current Evidence and Controversies.

Carbohydrate restriction has gained increasing popularity as an adjunctive nutritional therapy for diabetes management. However, controversy remains regarding the long-term suitability, safety, efficacy and potential superiority of a very low carbohydrate, ketogenic diet compared to current recommended nutritional approaches for diabetes management. Recommendations with respect to a ketogenic diet in clinical practice are often hindered by the lack of established definition, which prevents its capacity to be most appropriately prescribed as a therapeutic option for diabetes.

Teaching medical students about nutrition: from basic principles to practical strategies.

Poor nutrition is widely recognised as one of the key modifiable risks to health and life, with doctors in an ideal position to recognise when suboptimal nutrition is impacting on their patients' health and provide them with advice and support to create sustainable and achievable diet and lifestyle modifications. However, it has been acknowledged that nutrition training within medical schools is extremely varied, and in many cases inadequate. The Association for Nutrition UK Undergraduate Curriculum in Nutrition for Medical Doctors provides medical schools with guidance on what should be included in the training of all medical students.

A critical review exploring science communication of nutrition and dietetic research: a case-based approach exploring methodologies.

Background: Nutrition is an area of apparent disagreement among the public and experts. It is also an area which has seen a rapid increase in the number of publications in the past 40 years. With the advent of online media and social media platforms, the volume of news has also increased.

Physicochemical, antioxidant and sensory properties of Mango Sorbet containing L-theanine as a potential functional food product.

The non-proteinous amino acid L-theanine (L-THE) is associated with a range of health benefits including improvements in immune function, cardiovascular outcomes and cognition. The aims of this study were to develop a food product (mango sorbet; ms-L-THE) containing physiologically relevant doses of L-THE (0.2/100 g w/w) and determine its antioxidant, physicochemical and sensory properties in comparison to a mango sorbet without L-THE (ms).

Putting nutrition education on the table: development of a curriculum to meet future doctors' needs.

COVID-19 has further exacerbated trends of widening health inequalities in the UK. Shockingly, the number of years of life lived in general good health differs by over 18 years between the most and least deprived areas of England. Poor diets and obesity are established major risk factors for chronic cardiometabolic diseases and cancer, as well as severe COVID-19.

A narrative review of the functional components of human breast milk and their potential to modulate the gut microbiome, the consideration of maternal and child characteristics, and confounders of breastfeeding, and their impact on risk of obesity later in life.

Nutritional exposure and, therefore, the metabolic environment during early human development can affect health later in life. This can go beyond the nutrients consumed; there is evidence that the development and modulation of the gut microbiome during early life can affect human growth, development, and health, and the gut microbiome is associated with the risk of obesity later in life. The primary aim of this review was to evaluate existing evidence, to identify the components of human breast milk, which may modulate the gut microbiome, and to assess the impact of the gut microbiome on the risk of becoming obese later in life.

Exploring the Path of Mediterranean Diet, Non-Alcoholic Fatty Liver Disease (NAFLD) and Inflammation towards 10-Year Cardiovascular Disease (CVD) Risk: The ATTICA Study 10-Year Follow-Up (2002-2012).

Background: Non-alcoholic fatty liver disease (NAFLD) is the leading cause of liver disease, affecting ~30% of the population and increasing CVD. This study aimed to explore the direct, indirect and combined effects of Mediterranean diet, NAFLD and inflammation on the 10-year CVD risk in a healthy adult population.

Methods: Using baseline and 10-year follow-up data from the ATTICA study, adherence to Mediterranean diet was measured using MedDietScore, and presence of NAFLD at baseline was assessed using the fatty liver index (FLI).

Prickly Pear Cacti ( spp.) Cladodes as a Functional Ingredient for Hyperglycemia Management: A Brief Narrative Review.

The worldwide prevalence of obesity is increasing along with its comorbidities, including type 2 diabetes mellitus (T2DM). From a pathophysiological perspective, T2DM arises as a consequence of insulin resistance and pancreatic β-cell dysfunction, which together induce chronic hyperglycemia. The pharmacological treatment of T2DM specifically focuses on its management, rather than remission, with a lack of pharmacological agents to prevent the onset of the disease.

Association between lipids and apolipoproteins on type 2 diabetes risk; moderating effects of gender and polymorphisms; the ATTICA study.

Background And Aims: Type 2 diabetes mellitus (T2DM) is a condition defined by hyperglycaemia, but also often presents with dyslipidaemia and suppressed HDL cholesterol. Mendelian randomization studies have suggested a causal link between low HDL cholesterol and T2DM. However, influences of gender, polymorphisms and lifestyle, all known to influence HDL cholesterol, have not been fully explored in a prospective cohort.

Assessing the diet quality of individuals with rheumatic conditions: a cross-sectional study.

Arthritis is a significant cause of chronic pain and disability, affecting around 3.5 million Australians. However, little is known regarding the overall diet quality of those living with arthritis.

The Effects of Green Tea Amino Acid L-Theanine Consumption on the Ability to Manage Stress and Anxiety Levels: a Systematic Review.

The green tea amino acid, L-theanine (L-THE) is associated with several health benefits, including improvements in mood, cognition and a reduction of stress and anxiety-like symptoms. This systematic review evaluated the effect of pure L-THE intake, in the form of orally administered nutritional supplements, on stress responses and anxiety levels in human randomised controlled trials. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, 9 peer-reviewed journal articles were identified where L-THE as a supplement was compared to a control.

The Effects of Dietary Polyphenols on Circulating Cardiovascular Disease Biomarkers and Iron Status: A Systematic Review.

The prevalence of cardiovascular disease (CVD) is rising worldwide, remaining the major cause of death in developed countries. Polyphenols have been shown to have cardioprotective properties; however, their impact on iron bioavailability and potential impact on other aspects of health is unclear. A systematic review was undertaken to evaluate the current status of the relationship between habitual polyphenol consumption, iron status, and circulating biomarkers of CVD.

Effects of the Consumption of Prickly Pear Cacti () and its Products on Blood Glucose Levels and Insulin: A Systematic Review.

: There is confusion as to which component of the cacti has demonstrated anti-hyperglycemic effects or anti-diabetic properties. It is important to clarify these health benefits due to the increasing need for prevention and treatment of chronic diseases. The aim of this review is to identify the effects of cacti consumption on biomedical measures; glucose and insulin with consideration of its' components; fruit, leaf and combined or unidentified products.

The effect of blueberry interventions on cognitive performance and mood: A systematic review of randomized controlled trials.

Blueberries are rich in polyphenols that may be beneficial to cognitive performance and mood. The aim of this systematic review was to evaluate randomized controlled trials investigating the effects of blueberries and blueberry products on measures of cognition and mood. In total, eleven articles (that included 12 studies) were identified using freeze-dried blueberries (n = 9 studies), whole blueberries (n = 2) and blueberry concentrate (n = 1).

Relationship Between B-Vitamin Biomarkers and Dietary Intake with Apolipoprotein E є4 in Alzheimer's Disease.

The potential for B-vitamins to reduce plasma homocysteine (Hcy) and reduce the risk of Alzheimer's disease (AD) has been described previously. However, the role of Apolipoprotein E є4 (APOE4) in this relationship has not been adequately addressed. This case-control study explored APOE4 genotype in an Australian sample of 63 healthy individuals (female = 38; age = 76.

The beneficial health effects of green tea amino acid l-theanine in animal models: Promises and prospects for human trials.

l-Theanine (l-THE) is a nonproteinogenic amino acid derived from green tea (Camellia sinensis), which exhibits strong antioxidant-like properties and contributes to the favourable umami taste sensation. Several studies have reported that the consumption of this amino acid has many therapeutic effects, including improvements in brain and gastrointestinal function, cancer drug therapeutic efficacies, antihypertensive effects, and improved immune function. Considering the recent Western commercialisation and popularity of green tea consumption as a nootropic agent in humans, the aims of this review were to consolidate the existing knowledge from ex vivo and in vitro animal models and attempt to highlight the applicability of l-THE towards the human clinical trials.

The effects of grape and red wine polyphenols on gut microbiota - A systematic review.

There is a growing body of evidence implicating the gut 'microbiome' role in overall human health. Bacterial species belonging to the genera Lactobacillus and Bifidobacterium are generally considered to be beneficial and are commonly used in probiotic applications, whereas increases in some genera including Clostridum, Eubacterium and Bacteroides are implicated in negative health outcomes. Dietary polyphenols are bioactive compounds that have been found to increase the numbers of beneficial bacteria and antimicrobial actions against pathogenic bacteria, however most studies have been conducted in animal models or in-vitro colonic models.

Effect of long-term nutraceutical and dietary supplement use on cognition in the elderly: a 10-year systematic review of randomised controlled trials.

Nutraceuticals have generated interest as a way to mitigate the cognitive decline in older adults. The aim of this systematic review was to determine the evidence for these claims from the scientific literature in randomised, double-blinded, controlled trials (duration: ≥1 year; participants: n≥100; age(mean): ≥65 years). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched four electronic databases (PubMed, Scopus, CINAHL and Web of Science) and identified twenty-five studies published between the 15·June·2006 and 14·June·2016.

The effects of the Mediterranean diet on rheumatoid arthritis prevention and treatment: a systematic review of human prospective studies.

Rheumatoid arthritis is a progressive autoimmune disease characterised by severely swollen and painful joints. To compliment pharmacotherapy, people living with rheumatoid arthritis often turn to dietary interventions such as the Mediterranean diet. The aim of the present systematic review is to discuss the effects of the Mediterranean diet on the management and prevention of rheumatoid arthritis in human prospective studies.

Evaluation of dietary and lifestyle changes as modifiers of S100β levels in Alzheimer's disease.

There is a significant body of research undertaken in order to elucidate the mechanisms underlying the pathology of Alzheimer's disease (AD), as well as to discover early detection biomarkers and potential therapeutic strategies. One such proposed biomarker is the calcium binding protein S100β, which, depending on its local concentration, is known to exhibit both neurotrophic and neuroinflammatory properties in the central nervous system. At present, relatively little is known regarding the effect of chronic S100β disruption in AD.
