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
Infants and children are consuming increasing amounts of foods with added sugars, high in salt, and high in saturated or trans fats. Commercially prepared foods are more likely to be high in energy, low in nutrients (energy dense, nutrient-poor), and ultra-processed. The aim of this study was to examine, in children aged ≤10.9 y, the risks of greater consumption of unhealthy foods and beverages compared with no or low consumption on overweight and obesity. This study is a systematic review and meta-analysis which included the summarized characterises of 71 articles from 60 included studies. Results indicate that in children aged ≤10.9 years, consumption of sugar-sweetened beverages and unhealthy foods may increase body mass index, percentage body fat, or the odds of overweight/obesity (low to very-low certainty). Furthermore, there was little or no difference to body mass index, percentage body fat, or overweight/obesity outcomes (low certainty) after consumption of artificially sweetened beverages and 100% fruit juices. Authors conclude that policy recommendations are needed to address the growing burden of overweight and obesity that children are experiencing worldwide.
Abstract
This WHO-commissioned review contributed to the update of complementary feeding recommendations, synthesizing evidence on effects of unhealthy food and beverage consumption in children on overweight and obesity. We searched PubMed (Medline), Cochrane CENTRAL and Embase for articles, irrespective of language or geography. Inclusion criteria were: 1) randomized controlled trials (RCTs); non-RCTs; cohort studies and pre/post studies with control; 2) participants ≤ 10.9 y at exposure; 3) studies reporting greater consumption of unhealthy foods/beverages vs. no or low consumption; 4) studies assessing anthropometric and/or body composition; and 5) publication date ≥ 1971. Unhealthy foods and beverages were defined using nutrient- and food-based approaches. Risk of bias was assessed using the ROBINS-I and RoB2 tools for non-randomized and randomized studies, respectively. Narrative synthesis was complemented by meta-analyses where appropriate. Certainty of evidence was assessed using GRADE. Of 26,542 identified citations, 60 studies from 71 articles were included. Most studies were observational (59/60), and no included studies were from low-income countries. The evidence base was low quality, as assessed by ROBINS-I and RoB2 tools. Evidence synthesis was limited by the different interventions and comparators across studies. Evidence indicated that consumption of sugar-sweetened beverages (SSB) and unhealthy foods in childhood may increase body mass index (BMI)/BMI z-score, % body fat or odds of overweight/obesity (low certainty of evidence). Artificially-sweetened beverages and 100% fruit juice consumption may make little/no difference to BMI, % body fat or overweight/obesity outcomes (low certainty of evidence). Meta-analyses of a subset of studies indicated a positive association between SSB intake and % body fat, but no association with change in BMI and BMI z-score. High-quality epidemiological studies that are designed to assess the effects of unhealthy food consumption during childhood on risk of overweight/obesity are needed to contribute to a more robust evidence base upon which to design policy recommendations.

Plain language summary
Mycotoxins are toxic substances produced by fungi, which can be found in common foods like maize, wheat, nuts, and foods containing them. Mycotoxins such as aflatoxins, ochratoxin, fumonisins, zearalenone, and some Penicillium toxins can alter genetic material. According to previous studies, they can damage genetic material and affect cell growth. Usage of chemicals such as fertilizers and fungicides is a common practice in the agricultural industry to protect plants from fungus and to feed them. However, fungicides can accelerate mycotoxin production. 16 studies were included in this Systematic Review and 11 in Meta-Analysis. This research looked at the harmful effects of mycotoxins such as aflatoxins, fumonisins, ochratoxin, T2, zearalenone, and some Penicillium toxins in causing cancers. The researchers evaluated the link between aflatoxin exposure and liver cancer, fumonisin B1 exposure and liver cancer, zearalenone exposure and breast cancer, zearalenone exposure and cervical cancer, citrinine and patulin exposure and colorectal cancer, and NEO, HT-2, and T-2 exposure and Oesophageal cancer. This research did not show significant associations between various mycotoxins and cancer risk. As currently, most studies are primarily focused on aflatoxin; more robust studies are needed to assess the cancer risk associated with different mycotoxin exposure. Using the results of this study, healthcare professionals can gain a better understanding of how mycotoxins affect our bodies.
Abstract
Humans continue to be constantly exposed to mycotoxins, mainly through oral exposure (dietary), inhalation, or dermal contact. Recently, it has been of increasing interest to investigate mycotoxin-linked carcinogenicity. This systematic review was conducted to synthesize evidence of the association between mycotoxin-linked mutations and the risk of cancer, to provide an overview of the data linking exposure to different mycotoxins with human cancer risk, and to provide an update on current research on the risk of cancer associated with human exposure to mycotoxins. PRISMA guidelines were used when conducting the systematic review. PubMed, MEDLINE, and CINAHL electronic databases were comprehensively searched to extract the relevant studies published from inception to May 2022. A total of sixteen relevant studies (4907 participants) were identified and included in this review. Of these, twelve studies were from Asia, while four of the studies were conducted in Africa. The overall meta-analysis result found no significant association, although some of the studies confirmed an association between mycotoxin-linked mutations and primary liver cancer risk. Mainly, the experimental studies have shown associations between mycotoxin-linked mutations and cancer risk, and there is a need for researchers to confirm these links in epidemiological studies in order to guide public health policies and interventions.

Clinical vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D) concentration below <30nmol/L) increases the risk of excess mortality and disease. Vitamin D deficiency, as measured by serum 25(OH)D, is particularly high among older Irish adults. The aim of this study was to investigate the cost-effectiveness of vitamin D3 supplementation in older adults in Ireland, with year-round vitamin D deficiency. This study investigated three age groups: (1) ≥50 years, (2) ≥60 years and (3) ≥70 years. Results show that cost-effectiveness of vitamin D3 supplementation is most robust in adults ≥70 years. Furthermore, the results of the cost-effectiveness analysis are most sensitive to the mortality risk reduction following vitamin D3 supplementation. Authors conclude by proposing the implementation of a GP-monitored, vitamin D3 supplementation programme for adults ≥70 years of age.
Abstract
Background: This study investigated the cost-effectiveness of vitamin D3 supplementation in older adults in Ireland, with year-round vitamin D deficiency (serum 25-hydroxyvitamin D concentration <30 nmol/L) (13% of Irish adults), from the perspective of the Health Service Executive. Methods: Three age groups were investigated: (1) ≥50 years, (2) ≥60 years and (3) ≥70 years. Based on the clinical literature, vitamin D3 supplementation may: (1) decrease all-cause mortality by 7% and (2) reduce hip fractures by 16% and non-hip fractures by 20%. A discount rate of 4% was applied to life years and quality-adjusted life years (QALYs) gained, and healthcare costs. The annual healthcare costs per patient used in the model are based on the average annual health resource use over the 5-year time horizon of the model. Results: The cost/QALY estimates in all three age groups are below the usually acceptable cost-effectiveness threshold of €20 000/QALY. The most cost-effective and least costly intervention was in adults ≥70 years. For this age group, the average annual costs and outcomes would be approximately €5.6 million, 1044 QALYs gained, with a cost/QALY of approximately €5400. The results are most sensitive to the mortality risk reduction following vitamin D3 supplementation. Conclusion: The cost-effectiveness of vitamin D3 supplementation is most robust in adults ≥70 years. Clinical uncertainty in the magnitude of the benefits of vitamin D3 supplementation could be further addressed by means of: (1) performing a clinical research study or (2) conducting a pilot/regional study, prior to reaching a decision to invest in a nationwide programme.

Plain language summary
The prevalence of obesity and associated comorbidities such as Type 2 diabetes can be reduced by implementing population-wide weight loss dietary strategies. A very low-calorie diet (VLCD) has been considered a successful dietary strategy for people with Type 2 diabetes and obesity. A total of 325 people participated in this long-term observational study. Female participants consumed 450 kcal/day, and male participants consumed 650 kcal/day for at least three months. This 15-year follow-up retrospective study looked at the effects of VLCD in obese participants. In the 15-year follow-up, only 5.9% of participants maintained >10kg weight loss. However, 95% of participants gained weight after 15 years. Ten participants went into diabetes remission after three months of VLCD intervention. The results showed no positive effects of VLCD on diabetes remission after 15 years. However, there was a higher incidence of cardiovascular disease among participants who had considerable weight loss after the VLCD intervention. Further robust studies are required to evaluate the relationship between weight loss and the incidence of cardiovascular disease. However, healthcare professionals can use the results of this study to understand the short-term benefits of VLCD and the long-term impact of the obesogenic environment on the health of the general population.
Abstract
Objective: To assess weight loss maintenance, diabetes status, mortality and morbidity 15 years after a very low calorie diet programme (VLCD) in patients with obesity. Design: General practice data bases were interrogated for subjects coded for group therapy with VLCD in the 1990s. Causes of death, occurrence of vascular disease and remission or development of diabetes were ascertained from patient records and national stroke and cardiovascular disease data bases. Results: 325 subjects engaged in the programme and had sufficient data for analysis. Baseline characteristics were: age 47.8±12. 8 years; body mass index (BMI) 36.1±6.8 kg/m2; 79.1% female/20.9% male; 13.5% had type 2 diabetes. After 15±4 years weight had changed from 97.9±19 kg at baseline to 100±20.8 kg. 10 with diabetes at baseline were in remission at 3 months, but only two remained in remission at 5 years. 50 new cases of type 2 diabetes and 11 of impaired fasting glucose developed during follow-up. Only 5.9% who remained healthy at follow-up had maintained >10% body weight reduction. Neither diabetes incidence nor diabetes free survival were related to percentage body weight lost during VLCD. Only baseline BMI was related to development of new impaired fasting glucose or diabetes by 15 years (p=0.007). 37 subjects had a cardiovascular event. Age (p=0.000002) and degree of weight loss after VLCD (p=0.03) were significantly associated with subsequent vascular events. Conclusion: Long-term maintenance of weight loss after VLCD was rare in this single centre retrospective study 15 years later. Glucose intolerance developed in 21.4%. Lasting remission of type 2 diabetes or prevention of later glucose intolerance were not achieved. Vascular events were more frequent in those who lost most weight. Risk management during weight regain should be studied in future to assess potential for reduction in adverse cardiovascular outcomes.

Plain language summary
The European Commission and WHO have updated their approach to addressing obesity and promoting healthy eating among the general population. Foods that are high in calories, fat, sugar, and salt provide little nutritional value and are calorie dense. Price interventions, like the levy introduced by the UK government, have effectively reduced consumption of alcohol, tobacco, and sugary drinks. Both the UK and Scottish governments have recently proposed legislation to restrict the promotion of unhealthy foods. This longitudinal regression analysis assessed the consumer microdata over time to determine the effectiveness of price, price promotions, and volume promotions in predicting reductions in household purchases of high-fat, salt, and sugar (HFSS) foods. The results revealed that in-store promotions led to a significant increase in household purchasing. Volume promotions were more effective than price promotions, but they resulted in greater calorie intake per household. Additionally, there were significant differences in purchasing behaviour and income levels of households. Households with children tended to purchase more than those without. These findings suggest that policies aimed at limiting promotions may help reduce household purchases and consumption of HFSS foods. Healthcare professionals can utilise the outcomes of this review to comprehend the correlation between price and volume promotions on household buying and consumption of HFSS foods.
Abstract
Objectives: Taxes and restrictions on promotions have recently been proposed as policy instruments to reduce consumption of unhealthy foods. The objective of this study is to add to the limited evidence on the comparative effectiveness of price changes, price promotions and volume promotions in changing household purchasing of unhealthy foods, using biscuits, crisps and savoury snacks as examples. Design: Longitudinal regression analysis of consumer microdata. Setting: Secondary data on itemised household purchases of biscuits, crisps and savoury snacks from 2006 to 2012. Participants: Sample of 3024 households in Scotland. Main outcome measures: Changes in the number of calories (kcal) purchased in the product category by a household caused by changes in the price for the product category, any temporary in-store price promotions and any temporary in-store volume promotions. Changes are measured at the mean, median, 25th percentile and 75th percentile of the household purchasing distribution for the full sample. Subgroup analyses were conducted by household income band and for households with and without children. Results: Between product categories, the scale of purchasing response to incentives varies significantly. Within product categories, the mean calories (kcal) purchased by a household are more responsive to any volume promotion than to price or any price promotion for all product categories. As the volume of items purchased increases, households are less responsive to price, less responsive to any volume promotion and more responsive to any price promotion. Statistically significant differences are observed between household income groups in their response to price and promotion incentives within the biscuits category only. In cases where statistically significant differences are observed, households with children are more responsive to promotion and price incentives than households without children. Conclusions: For all product categories analysed (biscuits, crisps and savoury snacks), household purchasing is most responsive to any volume promotion. Therefore, assuming the response of consumers to incentives remains constant following legislation, the most effective policy instrument to reduce the calorie intake from these products may be a ban on volume promotions.

Obesity and diabetes mellitus (DM) account for the highest burden of non-communicable diseases. Obesity is also highly comorbid with type 2 DM with a prevalence of 8.5% among adults around the globe. The aims of this study were to present (a) a critical synthesis of the theoretical basis and development of therapeutic patient education (TPE) interventions for obesity and diabetes, and (b) quantitative evidence for the efficacy of these interventions across a range of biomedical, psychosocial and psychological outcomes. This study is a systematic review and meta-analysis of fifty-four randomised controlled trials. Results show that: - TPE interventions bring about significant improvements in biomedical outcomes among patients with DM and obesity. - there weren’t significant differences in the quality of life of participants undergoing TPE interventions (inconclusive as only data from two studies were considered). - interventions delivered through different media and delivery formats may be equally effective. Authors conclude that the use of electronic media such as short messaging services, website-based educational programs and animation media can be used to deliver TPE effectively.
Abstract
Diabetes mellitus (DM) and obesity account for the highest burden of non-communicable diseases. There is increasing evidence showing therapeutic patient education (TPE) as a clinically and cost-effective solution to improve biomedical and psychosocial outcomes among people with DM and obesity. The present systematic review and meta-analysis present a critical synthesis of the development of TPE interventions for DM and obesity and the efficacy of these interventions across a range of biomedical, psychosocial and psychological outcomes. A total of 54 of these RCTs were identified among patients with obesity and diabetes and were thus qualitatively synthesized. Out of these, 47 were included in the quantitative synthesis. There was substantial heterogeneity in the reporting of these outcomes (I2 = 88.35%, Q = 317.64), with a significant improvement noted in serum HbA1c levels (standardized mean difference (SMD) = 0.272, 95% CI: 0.118 to 0.525, n = 7360) and body weight (SMD = 0.526, 95% CI: 0.205 to 0.846, n = 1082) in the intervention group. The effect sizes were comparable across interventions delivered by different modes and delivery agents. These interventions can be delivered by allied health staff, doctors or electronically as self-help programs, with similar effectiveness (p < 0.001). These interventions should be implemented in healthcare and community settings to improve the health outcomes in patients suffering from obesity and DM.

Non-alcoholic fatty liver disease (NAFLD) has emerged as the predominant cause of chronic liver disease. Given the association between NAFLD and metabolic syndrome [11,12], lifestyle modification can improve patients’ life quality and prognosis. The aim of this study was to assess the joint association of several modifiable lifestyle factors with overall and cause-specific mortality among NAFLD individuals and depict the mortality risk of varied composite modes of lifestyle. This study is a large, nationally representative, population-based study. It is based on the NHANES III (1988–1994, the National Center for Health Statistics, the Center for Disease Control and Prevention), which used a complex multistage probability design to recruit a representative sample of participants. Results show a protective effect among NAFLD participants following a healthy lifestyle, particularly impacting CVD-related mortality. Notably, among the most common lifestyle factor combinations, the effect of risk reduction on mortality was particularly strong when smoking was avoided. Authors conclude that their findings can be a useful tool to help the general public and patients with NAFLD to understand the importance of maintaining a healthy lifestyle.
Abstract
BACKGROUND AND AIMS It is unclear whether a healthy lifestyle impacts mortality in the presence of non-alcoholic fatty liver disease (NAFLD). The present study aimed to examine the joint association of several modifiable lifestyle factors with mortality risk for NAFLD patients. METHODS We collected lifestyle behavior data form the National Health and Nutrition Examination Survey (NHANES) III from 1988 to 1994 and follow-up data form NHANES III-linked mortality data through 2015. We estimated joint association between four healthy lifestyle factors (non-smoking, non-drinking, regular physical activity, a healthy diet) after NAFLD diagnosis and mortality using Cox proportional hazards regression models. RESULTS During a median of 22.83 years of follow-up, 2932 deaths occurred. The risk of all-cause mortality decreased significantly with the healthy lifestyle scores increasing (p < 0.001). NAFLD patients with a favorable lifestyle (3 or 4 healthy lifestyle factors) reduced 36% of all-cause mortality and 43% of cardiovascular disease (CVD) mortality compared with those with an unfavorable lifestyle (0 or 1 healthy lifestyle factor) (HR, 0.64 [95% CI, 0.50-0.81], 0.57 [95% CI, 0.37-0.88]). Compared with the non-NAFLD group, the number of NAFLD patients required to adhere to a favorable lifestyle to prevent one cardiovascular disease death in 20 years was fewer (77 vs. 125). CONCLUSIONS For the NAFLD patients, adopting a healthy lifestyle could significantly reduce their risk of death.

A growing body of evidence supports foods and nutrients as a potential means to prevent and reduce pain. Among the most promising is vitamin D. Low serum vitamin D concentrations are frequent among older adults and have also been associated with conditions such as widespread pain, muscle pain, arthritis, and low-back pain. The aim of this study was to study the association of habitual dietary vitamin D intake with (1) pain incidence and (2) pain changes over a 5-year follow-up in a cohort of community-dwelling older adults. This study is based on data from the Seniors-ENRICA-1 study, a cohort of community-dwelling adults ≥60 years in Spain. Results show that higher dietary vitamin D intake was associated with lower pain incidence and favourable pain changes over 5 years. These associations were consistent in main and sensitivity analyses and highlight the potential role of dietary vitamin D intake as an adjunctive pain prevention and management strategy. Authors conclude that diet is often measured with some error, can change over time, and its effects on health could be cumulative, larger observational studies with repeated assessment of vitamin D intake should replicate these findings.
Abstract
BACKGROUND Vitamin D plays a role in bone health, pain signaling, and inflammation. We examined the largely unknown relation of dietary vitamin D intake with pain incidence and pain changes over time in older adults. METHODS Data were taken from the Seniors-ENRICA-1 cohort, which included 950 individuals aged ≥60 years. Habitual vitamin D intake was assessed in 2012 with a validated diet history, and pain both in 2012 and 2017 with a scale ranging from 0 (no pain) to 6 (highest pain), according to its severity, frequency, and number of locations. Analyses on pain incidence and pain changes were performed in the 524 participants free of pain at baseline and the overall sample, respectively. RESULTS Higher dietary vitamin D intake was associated with lower 5-year pain incidence; the multivariable-adjusted odds ratio (95% confidence interval) was 0.88 (0.79,0.99) for every 1-µg/day increase in vitamin D intake, and 0.49 (0.28,0.88) for the highest (>3.52 µg/day) vs. lowest (<1.85 µg/day) tertile. Dietary vitamin D intake (highest vs. lowest tertile) was also associated with 5-year favorable pain changes: the multivariable-adjusted odds ratio of pain worsening vs. no change/pain improvement was 0.55 (0.36,0.86), and the β coefficient for changes in the pain scale was -0.56 (-1.03,-0.09). Similar results were found for pain severity, frequency, and number of pain locations. CONCLUSIONS In an older adult population, where compliance with vitamin D intake recommendations was very low, a slightly increased dietary intake was associated with lower pain incidence and favorable pain changes over 5 years.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is a condition resulting from excessive lipid accumulation in the liver in individuals with low alcohol consumption. Obesity is an established risk factor for the development of NAFLD, and 50% to 75% of people with obesity also have NAFLD. The aim of this study was to evaluate the association between Mediterranean diet and non-invasive indices of fatty liver in a large sample of women with overweight and obesity. This study is a cross-sectional study of 2967 consecutive women with overweight and obesity. Results show that higher adherence to the Mediterranean diet was associated with lower indices of fatty liver in women with overweight and obesity (particularly obese women than in women who are overweight). Authors conclude that women with obesity, especially during the premenopausal period, may benefit more from following a Mediterranean-style diet.
Abstract
Obesity is a risk factor for NAFLD. However, not all people with obesity have an excessive intrahepatic fat content. Adherence to a high-quality dietary pattern may also promote liver health in obesity. A cross-sectional study of 2967 women with overweight and obesity was carried out to assess the association between a Mediterranean diet and fatty liver. All women underwent clinical examination, anthropometric measurements, blood sampling, ultrasound measurements of abdominal visceral and subcutaneous fat, and assessment of adherence to the Mediterranean diet using the 14-item MEDAS questionnaire. Fatty liver index (FLI), NAFLD fatty liver steatosis (NAFLD-FLS) and hepatic steatosis index (HSI) were calculated. In women with obesity, the MEDAS score was inversely associated with FLI (β = -0.60, 95% CI: -1.04, -0.16, p = 0.008), NAFLD-FLS (β = -0.092, 95% CI: -0.134, -0.049, p < 0.001) and HSI (β = -0.17, 95% CI: -0.30, -0.04, p = 0.011). Stronger associations were observed in premenopausal women with obesity. Mediterranean diet was inversely associated with NAFLD-FLS in women with overweight, independently of menopausal status. In conclusion, Mediterranean diet is associated with a better liver status in women with overweight and obesity. This may have a public health impact and be useful in drafting nutritional guidelines for NAFLD.
