Plain language summary
As we age, collagen degrades, which can result in an increased risk for injuries and pain. Pain management largely focuses on drugs to control inflammation, which can result in side effects. Collagen is the predominant component of connective tissues and supplementation has been shown to have beneficial effects on joint pain and inflammation. This randomised control trial aimed to determine the effect of different doses of collagen over 3 different time periods on measures of pain, function, and mental and physical health in 86 active, middle-aged men and women. The results showed that daily activity was improved when individuals were given 10g/day collagen for at least 6 months. Pain was also improved with this dose for at least 6-months, but only in those who exercised more than 3 hours per week. Mental health improved with 10g/day when given for at least 3-9 months. Physical function was also improved with 20g/day collagen for at least 3-9 months, but only amongst women. It was concluded that 10-20g/day collagen supplementation for at least 6 months may improve pain, functionality, and mental health in healthy, middle-aged men and women. Women may particularly benefit from 20g/day collagen and enhanced effects may be seen when in combination with exercise. This study could be used by healthcare professionals to recommend collagen supplementation to improve joint pain and physical and mental health in combination with exercise.
Abstract
INTRODUCTION Chronic pain affects 19% of adults in the United States, with increasing prevalence in active and aging populations. Pain can limit physical activity and activities of daily living (ADLs), resulting in declined mental and social health. Nutritional interventions for pain currently target inflammation or joint health, but few influence both. Collagen, the most abundant protein in the human body and constituent of the extra cellular matrix, is such a nutraceutical. While there have been reports of reductions in pain with short-term collagen peptide (CP) supplementation, there are no long-term studies specifically in healthy middle-aged active adults. PURPOSE To determine the effects of daily CP consumption over 3, 6, and 9 months on survey measures of pain, function, and physical and mental health using The Knee Injury & Osteoarthritis Outcomes Score (KOOS) and Veterans Rand 12 (VR-12) in middle-aged active adults. METHODS This study was a double-blind randomized control trial with three treatment groups (Placebo, 10 g/d CP, and 20 g/d CP). RESULTS Improvements in ADLs (p = .031, ηp2 = .096) and pain (p = .037, ηp2 = .164) were observed with 10 g/d CP over 6 months, although pain only improved in high frequency exercisers (>180 min/week). Additionally, VR-12 mental component scores (MCS) improved with 10 g/d of CP over 3-9 months (p = .017, ηp2 = .309), while physical component scores (PCS) improved with 20 g/d of CP over 3-9 months, but only in females (p = .013, ηp2= .582). CONCLUSION These findings suggest 10 to 20 g/d of CP supplementation over 6 to 9 months may improve ADLs, pain, MCS, and PCS in middle-aged active adults.

Abstract
Rick Miller is a clinical and sports dietician who is trained in functional medicine. In this podcast he eloquently explores optimal nutrition and exercise for men to support physical performance and longevity. He discusses the nuances around men and masculinity and how men are less likely to seek support for whole host of common issues such as insulin resistance, mental health, gastric concerns and sexual dysfunction. Interestingly, dopamine excess has been shown to impact libido and he manages this via a dopamine fast and cold exposure. Rick reviews the evidence around macronutrients on testosterone levels and explains his rationale for using an animal based eating approach within his clinic.

Abstract
An insightful short read by the IFM raising awareness about gender norms around masculinity and the stigma of men’s mental health as barriers for support by practitioners. It suggests that men’s mental health issues may go unrecognised or undiagnosed due to presenting factors and the fact that men are in general less likely to seek support. The evidence for reducing mental health stigma in men and tailoring lifestyle interventions are discussed.

Plain language summary
It is well known that older people are at a higher risk for nutritional inadequacy which is accompanied by depression, impaired cognitive function, and poor overall health. In this secondary analysis of a randomised controlled assessor-blinded dietary intervention trial, the authors examined the effects of six months of nutritional therapy on quality of life, self-rated health, cognitive function, and depression in elderly patients aged 65 years and over. The participants in the intervention group received nutritional therapy (HOMEFOOD) education to overcome malnutrition, which included dietary recommendations to ensure an adequate nutritional intake of energy and protein through diet and additional supplemental protein and energy-rich foods. After six months of nutritional therapy, the intervention group showed improvement in cognitive function, self-rated health, depression score, and quality of life scores, as well as improvements in measures related to weight gain. Further studies need to be conducted in order to determine if nutritional therapy provides additional benefits to older people. However, healthcare professionals can use the results of this study to better understand how nutritional therapy can improve the quality of life and health of older people in comparison to standard care, so they can better advise their patients.
Abstract
BACKGROUND AND AIMS Malnutrition is common among older adults and is related to quality of life, cognitive function, and depression. To what extent nutrition interventions can improve these outcomes remains unclear. The aim of this study was to investigate the effect of nutrition therapy on health-related quality of life (EQ-5D), self-rated health, cognitive function, and depression in community dwelling older adults recently discharged from hospital. METHODS Participants (>65 years) were randomised into an intervention (n = 53) and a control group (n = 53). The intervention group received individualised nutrition therapy based on the nutrition care process including 5 home visits and 3 phone calls, in combination with freely delivered energy- and protein-rich foods and oral nutrition supplements for six months after hospital discharge. EQ-5D, self-rated health, Mini-Mental-State-Examination (MMSE), and the Centre for Epidemiologic Studies Depression - IOWA (CES-D) scale were measured at baseline and at endpoint. RESULTS Two subjects dropped out, one from each arm. The control group experienced an increase in depressive symptoms and a decrease in self-rated health during the study period, while the intervention group experienced increases in cognitive function, self-rated health, and EQ-5D resulting in significant endpoint differences between the groups: EQ-5D (0.102, P = 0.001); self-rated health: 15.876 (P < 0.001); MMSE 1.701 (P < 0.001); depressive symptoms: - 3.072 (P < 0.001); all in favour of the intervention group. Improvements during the intervention in MMSE, self-rated health, and CES-D were significantly related to body weight gain in a linear way. CONCLUSION Cognitive function and mental well-being worsen or stagnate in older adults who receive standard care after hospital discharge. However, a six-month nutrition therapy improves these outcomes leading to statistically and clinically significant endpoint differences between the groups. As improvements were related to body weight gain after hospital discharge, we conclude that the increase in dietary intake, with focus on energy and protein density, and changes in body weight might have contributed to better cognitive function and mental well-being in older adults after the intervention.

Plain language summary
In patients with severe mental disorders, motivation to follow a healthy diet and lifestyle might be low. A diet rich in fruits and vegetables may improve metabolic syndrome, cardiovascular health and mental health. This randomised community-based clinical trial included seventy-four patients with severe mental disorders out of which 37.8% of the participants had schizophrenia or related disorders, 29.7% had bipolar disorder, 25.7% had depressive disorder, 4.1% had a personality disorder, and 2.7% had obsessive-compulsive disorder. The intervention group followed a four-week food education programme (DIETMENT) aimed at promoting fruit and vegetable consumption. A five-month post-intervention analysis showed no increase in participants diagnosed with metabolic syndrome in the intervention group, but an increase in participants diagnosed with metabolic syndrome in the control group. There was a significant reduction in the glomerular filtrate rate in the intervention group. In patients with severe mental disorders, more studies should be conducted to examine the health-promoting effects of adding more fruits and vegetables to the diet. Health professionals can use the results of this study to understand how fruits and vegetables contribute to reducing metabolic syndrome and heart disease risk.
Abstract
OBJECTIVES The aim of this study is to determine the metabolic impact of a nutrition education program on metabolic parameters and the presence of metabolic syndrome (MetS). RESULTS Seventy-four patients were included (mean age, 48.7 years [Standard deviation, SD: 10.8], 55.4% men). The diagnoses of SMD were 37.8% schizophrenia and related disorders; 29.7% bipolar disorder; 25.7% depressive disorder; 4.1% personality disorders; and 2.7% obsessive compulsive disorders. Thirty-seven individuals were distributed in both the intervention group (IG) and the control group (CG). In the IG the presence of MetS was 56.3% and in the CG 46.7%, with no statistically significant difference (p = 0.309). At the end of the study, glomerular filtrate decreased in the IG, body mass index and abdominal perimeter increased in both groups, and there were no changes in metabolic parameters between the groups. Between the baseline and the end of the study, there was no increase in the number of patients diagnosed with MetS (14 at both points); and in the CG the increase was from 8 to 12 (p = 0.005). An intervention based on fruit and vegetable intake could prevent progression to MetS in individuals with SMD, decreasing the likelihood of cardiovascular disease. Trial registration The trial was retrospectively registered on International Standard Randomised Controlled Trial Number (ISRCTN) Register on 11 March 2022 (ISRCTN12024347).

Plain language summary
Sleep deprivation is a common problem among adolescents. There has been an increase in the consumption of energy drinks among adolescents in recent years. It is well known that energy drinks contain caffeine, sugar, and amino acids such as taurine, B vitamins, Ginseng, and guarana, which have psychoactive properties and disrupt the circadian rhythm. Insufficient sleep can affect genes involved in circadian rhythm and serotonin pathways, resulting in a higher risk of developing mental health problems. Therefore, researchers accessed the data from a population-based cross-sectional study to evaluate the effect of an energy drink on sufficient sleep in male and female adolescents. This study found that high energy drink consumption negatively affected sufficient sleep in male and female adolescents, with boys consuming energy drinks more frequently. The intake of vegetables and water, as well as regular physical activity, were positively correlated with adequate sleep in male adolescents. Physical activity and sufficient sleep were positively correlated in girls. Girls who used sedatives were less likely to get sufficient sleep. In order to determine how the different ingredients of energy drinks affect the sleep quality and neurodevelopment of adolescents individually and synergistically, further robust studies are required. The results of this study may help healthcare professionals to understand the adverse effects of energy drinks on adolescents.
Abstract
Many adolescents worldwide have the problem of meeting recommended nightly sleep hours. The causes of sleep disturbance are multifactorial, but interest in food's effect on sleep has dramatically increased lately. In this study, we investigated the association between regular energy drink (ED) intake (weekly or more frequent) and sufficient sleep (SS) (≥8 h) in adolescents. Additional objectives were to examine the relationship between health-related behaviors and SS, stratified by gender. A population-based cross-sectional study was conducted during the 2019/2020 school year from 12 schools in Belgrade. There were 1287 students aged 15 to 19 who participated (37.4% male). We used a modified version of the food frequency questionnaire adapted for Serbian adolescents. Logistic regression revealed that regular ED consumption was an independent risk factor negatively related to SS in both sexes. Additionally, daily vegetable and water intake (≥2 L) showed a positive correlation with SS in boys, while in girls, the odds of realizing SS decreased with statements of sedative use. In conclusion, we show that ED intake is negatively associated with SS in both sexes; daily vegetable and water intake (≥2 L) may raise the odds of SS in boys, while sedative use may decrease the chances of SS in girls.

Plain language summary
In Europe, gestational diabetes affects approximately 10.9% of pregnant women. According to previous research, the cardiometabolic health of the mother and the mother's dietary habits during pregnancy may affect the foetus' neurodevelopment. Taking polyphenol supplements and eating foods rich in polyphenols is beneficial for promoting health across generations. In this systematic review, fourteen studies were included in order to evaluate the effects of polyphenols on gestational diabetes and mental health in the offspring. A higher prevalence of neurodevelopmental diseases in offspring is associated with gestational diabetes. The results of this systematic review revealed that polyphenol intake during pregnancy might have a beneficial effect on improving cardiometabolic health, reducing inflammation, DNA methylation and oxidative stress, thus reducing the risk of developing fetal neurodevelopmental disorders, such as attention deficit hyperactivity disorder, autism spectrum disorder and learning disorders. There is a need for further robust research, as the existing evidence regarding the safety of long-term polyphenol supplementation and its effects on gestational diabetes and fetal neurodevelopment is very limited. In spite of this, healthcare professionals can use the findings of this systematic review to learn more about the positive health benefits of polyphenols in pregnant women.
Abstract
The intake of foods containing polyphenols can have a protective role to avoid comorbidities during pregnancy and, at the same time, promote transgenerational health. This review aims to describe the effect of polyphenol intake through supplements or polyphenol-rich foods during pregnancy on the incidence and evolution of gestational diabetes mellitus (GDM), as well as the link with the neurodevelopment of the fetus. Using PRISMA procedures, a systematic review was conducted by searching in biomedical databases (PubMed, Cinahl and Scopus) from January to June 2022. Full articles were screened (n = 419) and critically appraised. Fourteen studies were selected and were divided into two different thematic blocks considering (i) the effect of polyphenols in GDM and (ii) the effect of GDM to mental disorders in the offspring. A positive relationship was observed between the intake of polyphenols and the prevention and control of cardiometabolic complications during pregnancy, such as GDM, which could be related to thwarted inflammatory and oxidative processes, as well as neuronal factors. GDM is related to a greater risk of suffering from diseases related to neurodevelopment, such as attention deficit hyperactivity disorder, autism spectrum disorder and learning disorder. Further clinical research on the molecule protective mechanism of polyphenols on pregnant women is required to understand the transgenerational impact on fetal neurodevelopment.

Plain language summary
Coronavirus disease 2019 (COVID-19) is one of the most serious infectious disease outbreaks in recent history. Among the factors that can increase the risk of obesity, some seem to play a more prominent role than others such as depression, emotional eating, sedentary lifestyle and the socioeconomic status. The aim of this study was to explore the indirect effects of the first year of COVID-19 on obesity and its risk factors. This study is a systematic review of 87 studies with over 350,000 participants. Results show that: - overall, there was a general trend of weight gain during the pandemic. - there were differences in dietary changes, with some studies showing an improvement in diet. - some beneficial effects were observed in the dieting domain, such as higher consumption of home-cooked meals and healthy food (e.g., vegetables). However, there was an increasing trend in the overall food and alcohol consumption. - financial hardship and job loss were unavoidable consequences of the pandemic lockdown. However, although the impact of the countermeasures used to curb the COVID-19 pandemic was evident on obesity risk factors, none of the studies included in the research explored the direct impact of the risk factors on obesity itself. Authors conclude by pointing out the need for future research that aims at strengthening the link between stressful circumstances and a rise in risk factors for obesity and weight gain.
Abstract
Obesity is increasingly prevalent worldwide. Associated risk factors, including depression, socioeconomic stress, poor diet, and lack of physical activity, have all been impacted by the coronavirus disease 2019 (COVID-19) pandemic. This systematic review aims to explore the indirect effects of the first year of COVID-19 on obesity and its risk factors. A literature search of PubMed and EMBASE was performed from 1 January 2020 to 31 December 2020 to identify relevant studies pertaining to the first year of the COVID-19 pandemic (PROSPERO; CRD42020219433). All English-language studies on weight change and key obesity risk factors (psychosocial and socioeconomic health) during the COVID-19 pandemic were considered for inclusion. Of 805 full-text articles that were reviewed, 87 were included for analysis. The included studies observed increased food and alcohol consumption, increased sedentary time, worsening depressive symptoms, and increased financial stress. Overall, these results suggest that COVID-19 has exacerbated the current risk factors for obesity and is likely to worsen obesity rates in the near future. Future studies, and policy makers, will need to carefully consider their interdependency to develop effective interventions able to mitigate the obesity pandemic.
