Plain language summary
Chronic inflammation is thought to be an underlying cause of many chronic diseases and diet can be used to modulate inflammation. The dietary inflammatory index (DII) is a tool rating an individual’s diet as pro- or anti-inflammatory, with an anti-inflammatory diet (low DII) being associated with a reduced risk of cardiometabolic disease. The aim of this 6-month randomised controlled trial was to evaluate the effect of a Mediterranean diet (MedD), as compared to a typical Australian diet (AusD), on DII and cardiometabolic risk factors in healthy Australians aged 65 years or older. Participants on the MedD significantly decreased their DII and had reductions in F2-Isoprostanes (marker of oxidative stress), triglycerides and systolic BP at 3 months and 6 months as well as improved endothelial function at 6 months. However, changes in DII did not correlate with changes in cardiometabolic risk factors. Evaluation of baseline parameters of both groups combined showed associations of DII with BMI, weight, abdominal fat, HDL and systolic blood pressure, with a lower DII correlating with lower risks. The authors concluded that a MedD decreases the DII which may help reduce the risk of cardiovascular disease.

Summary Review:
Introduction
- Chronic inflammation is thought to be an underlying cause of many chronic diseases.
- The dietary inflammatory index (DII) is a tool for rating an individual’s diet as pro- or anti-inflammatory. A low DII (anti-inflammatory diet) is associated with reductions in cardiometabolic diseases.
- The aim of the study was to evaluate the effect of a dietary intervention (Mediterranean diet) on DII and cardiometabolic risk factors in older Australians.
Methods
- Randomised controlled trial.
- Duration: 6 months.
- Participants: 152 healthy Australian men and women aged 65 years or older.
- Intervention: Traditional Mediterranean diet (MedD, fortnightly sessions with dietician); control: Habitual Australian diet (AusD)
- Outcome measures: DII and energy-adjusted DII (E-DII), blood pressure (BP), anthropometric parameters, endothelial function (measured as flow mediated dilatation, FMD), F2-isoprostanes (F2-IsoP, marker of oxidative stress), inflammatory biomarkers, lipids, glucose, insulin, dietary compliance, cognitive performance.
Results
- Over the 4 months, the E-DII decreased by 1.1 points in the MedD group (<0.001), but did not decrease in the AusD group (p=0.21).
- Compared to AusD, participants on MedD had reductions in F2-IsoP, triglycerides and systolic BP at 3 months and 6 months; improved endothelial function at 6 months (no p-values given as reported elsewhere).
- No associations between changes in DII and changes in cardiometabolic outcomes, independent of whether participants were normal or overweight.
- Baseline E-DII scores of both groups combined were divided into tertiles and associations with cardiometabolic parameters evaluated (p-values refer to highest vs lowest tertile):
- Higher E-DII was associated with higher BMI (p=0.04); body weight (p<0.0001); hip-to-waist ratio (p=0.001) and abdominal fat (p=0.03).
- Lower E-DII was associated with higher HDL cholesterol (p=0.04) and lower systolic BP (p=0.005).
- No associations between E-DII and other outcome measures.
Conclusion
- The authors concluded that adherence to a MedD reduces dietary inflammation index scores, which may be beneficial for reducing chronic disease risk.
Clinical practice applications:
- The Mediterranean diet lowers dietary inflammatory index scores. This may, in turn, help reduce risk of cardiometabolic disease.
Considerations for future research:
- Larger and longer-term trials may confirm whether or not the reduction of DII with a MedD translates into a reduction in measurable inflammation and cardiovascular disease.
Abstract
Increasing evidence supports that a higher dietary inflammatory index (DII®) score is associated with inflammation and cardiovascular disease (CVD) risk, events, and mortality. This randomized trial sought to determine if a change to a Mediterranean diet resulted in a reduction in the DII score, and then it evaluated the relationship between the DII and cardiometabolic outcomes following the administration of a traditional Mediterranean diet in older Australian adults. A total of 152 Australian adults (mean age 71 ± 5 years) was randomly allocated either a MedDiet (n = 80) or to continue their habitual diet (HabDiet) (n = 72) for 6 months. Diet and cardiovascular outcomes were measured at baseline and 3 and 6 months of the intervention. DII and energy-adjusted DII (E-DIITM) scores were calculated from 3-day weighed food records. There was a significant reduction in the DII score at 2 and 4 months for the MedDiet group (−1.40 ± 0.20 p < 0.001 and −1.47 ± 0.20 p < 0.001, respectively), which was significantly different from the HabDiet group over time (p < 0.001). The HabDiet DII score did not change significantly at the 2 and 4 months timepoints (0.47 ± 0.21 p = 0.35 and 0.54 ± 0.21 p = 0.21, respectively). The improvement in the DII in the MedDiet group was not related to any cardiometabolic outcome. Baseline cross-sectional analyses identified a positive association between the E-DII score and average BMI, body weight, WHR, abdominal adiposity, and SBP, and a negative association with HDL-C. We demonstrate that a MedDiet intervention significantly reduced DII scores compared with a habitual Australian diet in older Australians. This could be beneficial for healthy ageing and the avoidance of chronic disease in Western populations.

Diet is a fundamental determinant of metabolic health and immune regulation. Long-term dietary patterns also play an important role in shaping the intestinal commensal microbiota. The aim of this study was to explore the effects of an-8 week Mediterranean Diet enriched with dairy foods on the gut microbiome of Australian adults at risk of cardiovascular disease. This study was a randomised controlled trial with a 2 × 2 cross-over design. Participants followed a Mediterranean diet with 3–4 daily serves of dairy foods of 1000–1300mg per day (MedDairy) or low-fat diet (LFD) diet intervention for 8 weeks, separated by an 8-week washout phase where participants returned to their habitual diet. Participants (n= 43) were randomly assigned to their first dietary phase. Results showed that compared to the LFD (control), the MedDairy diet did not result in broad changes to the gut microbiota but significantly altered the relative abundance of selected bacterial taxa. Furthermore, microbial changes, including an increase in Butyricicoccus, were inversely correlated with changes in systolic blood pressure. Authors conclude that an 8-week MedDiet supplemented with dairy foods results in relative abundance changes in bacterial taxa.
Abstract
The impact of a Mediterranean diet on the intestinal microbiome has been linked to its health benefits. We aim to evaluate the effects of a Mediterranean diet supplemented with dairy foods on the gut microbiome in Australians at risk of cardiovascular disease. In a randomised controlled cross-over study, 34 adults with a systolic blood pressure ≥120 mmHg and with risk factors for cardiovascular disease were randomly allocated to a Mediterranean diet with 3-4 daily serves of dairy foods (Australian recommended daily intake (RDI) of 1000-1300 mg per day (MedDairy)) or a low-fat (LFD) control diet. Between each 8-week diet, participants underwent an 8-week washout period. Microbiota characteristics of stool samples collected at the start and end of each diet period were determined by 16S rRNA amplicon sequencing. MedDairy-associated effects on bacterial relative abundance were correlated with clinical, anthropometric, and cognitive outcomes. No change in the overall faecal microbial structure or composition was observed with either diet (p > 0.05). The MedDairy diet was associated with changes in the relative abundance of several bacterial taxa, including an increase in Butyricicoccus and a decrease in Colinsella and Veillonella (p < 0.05). Increases in Butyricicoccus relative abundance over 8 weeks were inversely correlated with lower systolic blood pressure (r = -0.38, p = 0.026) and positively correlated with changes in fasting glucose levels (r = 0.39, p = 0.019), specifically for the MedDairy group. No significant associations were observed between the altered taxa and anthropometric or cognitive measures (p > 0.05). Compared to a low-fat control diet, the MedDairy diet resulted in changes in the abundance of specific gut bacteria, which were associated with clinical outcomes in adults at risk of CVD.

Abstract
BACKGROUND Several clinical trials have examined diet and physical activity lifestyle changes as mitigation strategies for risk factors linked to cognitive decline and dementias such as Alzheimer's disease. However, the ability to modify these behaviors longer term, to impact cognitive health has remained elusive. OBJECTIVE The MedWalk trial's primary aim is to investigate whether longer-term adherence to a Mediterranean-style diet and regular walking, delivered through motivational interviewing and cognitive-behavioral therapy (MI-CBT), can reduce age-associated cognitive decline and other dementia risk factors in older, independently living individuals without cognitive impairment. METHODS MedWalk, a one-year cluster-randomized controlled trial across two Australian states, recruited 60-90-year-old people from independent living retirement villages and the wider community. Participants were assigned to either the MedWalk intervention or a control group (maintaining their usual diet and physical activity). The primary outcome is 12-month change in visual memory and learning assessed from errors on the Paired Associates Learning Task of the Cambridge Neuropsychological Test Automated Battery. Secondary outcomes include cognition, mood, cardiovascular function, biomarkers related to nutrient status and cognitive decline, MI-CBT effectiveness, Mediterranean diet adherence, physical activity, quality of life, cost-effectiveness, and health economic evaluation.Progress and Discussion:Although COVID-19 impacts over two years necessitated a reduced timeline and sample size, MedWalk retains sufficient power to address its aims and hypotheses. Baseline testing has been completed with 157 participants, who will be followed over 12 months. If successful, MedWalk will inform interventions that could substantially reduce dementia incidence and ameliorate cognitive decline in the community.

Abstract
Long term nut consumption is associated with reduced risk of coronary heart disease and better cognitive function. This study examined supplementing habitual diets with almonds or carbohydrate-rich snack foods (providing 15% energy) on biomarkers of cardiovascular and metabolic health, mood and cognitive performance. Participants (overweight/obese, 50-80 years) were randomised to an almond-enriched diet (AED) or isocaloric nut-free diet (NFD) for 12 weeks. Body weight, blood lipids, glucose, insulin, blood pressure (BP), arterial stiffness, cell adhesions molecules, C reactive protein (CRP), mood, and cognitive performance (working memory primary outcome), dietary profiles and energy intake/expenditure were measured at baseline and Week 12 in 128 participants (n = 63 AED, n = 65 NFD). Compared with NFD, AED was associated with altered macro and micronutrient profiles, but no differences in energy intake or expenditure. The AED significantly reduced triglycerides and SBP but there were no other changes in cardiometabolic biomarkers, mood, or cognitive performance. The inclusion of almonds in the diet improves aspects of cardiometabolic health without affecting cognitive performance or mood in overweight/obese adults.

Nutritional neuroscience. 2020;(8):646-658
Abstract
Background The Mediterranean diet has been linked to improved cognitive function and reduced risk of dementia. However, a traditional Mediterranean diet may not meet calcium requirements for older non-Mediterranean populations, which could limit long-term sustainability in Western countries. The current study therefore aimed to determine the cognitive and psychological effects of a Mediterranean diet with adequate calcium for an ageing Australian population. Method: A randomized controlled cross-over design trial compared a Mediterranean diet with 3-4 daily serves of dairy food (MedDairy) with a low-fat (LF) control diet. Forty-one participants aged ≥45 years with systolic blood pressure ≥120 mm Hg and at least two other risk factors for cardiovascular disease completed each dietary intervention for 8 weeks, with an 8-week washout period separating interventions. Attention, processing speed, memory and planning were assessed at the start and end of each intervention using the Cambridge Automated Neuropsychological Test Battery. Mood and health-related quality of life were evaluated using the Profile of Mood States (POMS) and Short-Form Health Survey (SF-36). Dementia risk was also measured using the Framingham Vascular Risk and CAIDE scores. Results Significant improvements were observed for processing speed (P = .04), Total Mood Disturbance (P = .01), Tension (P = .03), Depression (P = .03), Anger (P = .02), and Confusion (P = .004) following the MedDairy intervention. No significant effects were found for attention, memory and planning, or measures of dementia risk. Conclusion Our study provides evidence that a Mediterranean diet supplemented with dairy foods may benefit cognitive function and psychological well-being in an ageing population at risk of dementia.

The British journal of nutrition. 2019;(8):873-883
Abstract
The Mediterranean diet offers a range of health benefits. However, previous studies indicate that the restricted consumption of red meat in the diet may affect long-term sustainability in non-Mediterranean countries. A 24-week randomised controlled parallel cross-over design compared a Mediterranean diet supplemented with 2-3 serves per week of fresh, lean pork (MedPork) with a low-fat control diet (LF). Thirty-three participants at risk of CVD followed each intervention for 8 weeks, with an 8-week washout period separating interventions. The primary outcome was home-measured systolic blood pressure. Secondary outcomes included diastolic blood pressure, fasting lipids, glucose, insulin, C-reactive protein (CRP), body composition and dietary adherence. During the MedPork intervention, participants achieved high adherence to dietary guidelines. Compared with the MedPork intervention, the LF intervention led to greater reductions in weight (Δ = -0·65; 95 % CI -0·04, -1·25 kg, P = 0·04), BMI (Δ = -0·25; 95 % CI -0·03, -0·47 kg/m2, P = 0·01) and waist circumference (Δ = -1·40; 95 % CI -0·45, -2·34 cm, P < 0·01). No significant differences were observed for blood pressure, lipids, glucose, insulin or CRP. These findings indicate that Australians are capable of adhering to a Mediterranean diet with 2-3 weekly serves of fresh, lean pork. Larger intervention studies are now required to demonstrate clinical efficacy of the diet in populations with elevated blood pressure.

Plain language summary
Dementia is characterised by severe cognitive impairment and reduced quality of life. Observational studies have demonstrated that populations following a traditional Mediterranean diet experience less cognitive decline and a lowered risk of dementia. The aim of this study was to examine a Mediterranean diet modified to include 2–3 fresh servings of pork each week across measures of cognitive function and well-being. The study is a 24-week parallel randomised controlled crossover design to compare a Mediterranean diet with 2-3 weekly servings of fresh, lean pork (MedPork) and a low-fat control diet (LF). It recruited adults aged 45–80 years due to their increased risk of developing cardiovascular disease. Results indicate that compared with the LF control diet, the MedPork intervention led to higher performance in the cognitive domain of processing speed and higher scores for the SF-36 subscale emotional role functioning. No significant differences were observed for other domains of cognitive function, nor for additional measures of psychological well-being. Authors conclude that the MedPork intervention can improve processing speed and mood in a population at risk of cardiovascular disease and therefore dementia.
Abstract
BACKGROUND The Mediterranean diet may be capable of improving cognitive function. However, the red meat restrictions of the diet could impact long-term adherence in Western populations. The current study therefore examined the cognitive effects of a Mediterranean diet with additional red meat. METHODS A 24-week parallel crossover design compared a Mediterranean diet with 2-3 weekly servings of fresh, lean pork (MedPork) and a low-fat (LF) control diet. Thirty-five participants aged between 45 and 80 years and at risk of cardiovascular disease followed each intervention for 8 weeks, separated by an 8-week washout period. Cognitive function was assessed using the Cambridge Neuropsychological Test Automated Battery. Psychological well-being was measured through the SF-36 Health Survey and mood was measured using the Profile of Mood States (POMS). RESULTS During the MedPork intervention, participants consumed an average of 3 weekly servings of fresh pork. Compared to LF, the MedPork intervention led to higher processing speed performance (p = 0.01) and emotional role functioning (p = 0.03). No other significant differences were observed between diets. CONCLUSION Our findings indicate that a Mediterranean diet inclusive of fresh, lean pork can be adhered to by an older non-Mediterranean population while leading to positive cognitive outcomes.

The psychological burden of living with type 2 diabetes (T2D) has far reaching effects, negatively impacting quality of life, physical health and emotional wellbeing. It has been suggested that health-related quality of life (HRQoL) changes in response to weight status however this has not yet been explored in individuals with T2D. The aim of this randomised controlled study was to compare the effects of high protein and high carbohydrate diets, combined with moderate intensity exercise, on psychological wellbeing and HRQoL in 61 overweight adults with T2D. Participants enrolled in a 12-week weight loss period followed by a 12-week weight maintenance phase and blood glucose levels and various quality of life factors were assessed. This trial found in overweight adults with T2D, improvements in several psychological wellbeing and HRQoL were seen in response to modest weight loss and improvements in blood sugar levels. Improvements were seen in both high protein and high carbohydrate group, though a high protein diet may be better for maintaining control of blood glucose levels thus improving feelings of vitality. Based on this study, the authors conclude that it is imperative to address and support the psychological aspects of patients managing T2D.
Abstract
BACKGROUND Although higher-protein diets (HP) can assist with weight loss and glycemic control, their effect on psychological wellbeing has not been established. The objective of this study was to compare the effects of a HP and a higher-carbohydrate diet (HC), combined with regular exercise, on psychological wellbeing both during weight loss (WL) and weight maintenance phases (WM). METHODS In a parallel RCT, 61 adults with T2D (mean ± SD: BMI 34.3 ± 5.1 kg/m2, aged 55 ± 8 years) consumed a HP diet (29% protein, 34% carbohydrate, 31% fat) or an isocaloric HC diet (21%:48%:24%), with moderate intensity exercise, for 12 weeks of WL and 12 weeks of WM. Secondary data evaluating psychological wellbeing was assessed using: Problems Areas in Diabetes (PAID); Diabetes-39 Quality of Life (D-39); Short Form Health Survey (SF-36); Perceived Stress Scale-10 (PSS-10) and the Leeds Sleep Evaluation Questionnaire (LSEQ) at Weeks 0, 12 and 24 and evaluated with mixed models analysis. RESULTS Independent of diet, improvements for PAID; D-39 diabetes control; D-39 severity of diabetes; SF-36 physical functioning and SF-36 general health were found following WL (d = 0.30 to 0.69, P ≤ 0.04 for all) which remained after 12 weeks of WM. SF-36 vitality improved more in the HP group (group x time interaction P = 0.03). Associations were seen between HbA1c and D-39 severity of diabetes rating (r = 0.30, P = 0.01) and SF-36 mental health (r = - 0.32, P = 0.003) and between weight loss and PAID (r = 0.30, P = 0.01). CONCLUSION Several improvements in diabetes-related and general psychological wellbeing were seen similarly for both diets following weight loss and a reduction in HbA1c with most of these improvements remaining when weight loss was sustained for 12 weeks. A HP diet may provide additional increases in vitality. TRIAL REGISTRATION The trial was prospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN 12613000008729 ) on 4 January 2013.

Abstract
BACKGROUND The Mediterranean diet (MedDiet) offers benefits to cardiovascular health but may not meet Western recommendations for calcium and dairy intake, which could impede long-term adoption. OBJECTIVE The current study aimed to determine the effect of a MedDiet supplemented with dairy foods on cardiovascular risk factors. DESIGN A randomized, controlled, crossover design compared a MedDiet with 3-4 daily servings of dairy (MedDairy) and a low-fat (LF) control diet. Forty-one participants aged ≥45 y and at risk of cardiovascular disease (CVD) were randomly allocated to their first intervention, either the MedDairy or LF diet. Participants followed each intervention for 8 wk, and an 8-wk washout period separated interventions. The primary outcome was home-measured systolic blood pressure (SBP) assessed in the morning, afternoon, and evening. Secondary outcomes included clinic-measured blood pressure (morning), body composition, blood lipids, C-reactive protein (CRP), plasma glucose, serum insulin, and the Framingham Risk Score. RESULTS Compared with the LF intervention, the MedDairy intervention resulted in a significantly lower morning SBP (mean difference: -1.6 mm Hg; 95% CI: -2.8, -0.4 mm Hg; P = 0.01), lower morning diastolic blood pressure (mean difference: -1.0; 95% CI: -1.7, -0.2 mm Hg; P = 0.01) and clinic SBP (mean difference: -3.5 mm Hg; 95% CI: -6.4, -0.7 mm Hg; P = 0.02), significantly higher HDL cholesterol (mean difference: 0.04 mmol/L; 95% CI: 0.01, 0.06 mmol/L; P < 0.01), lower triglycerides (mean difference: = -0.05 mmol/L; 95% CI: -0.08, -0.01 mmol/L; P < 0.01), and lower ratio of total to HDL cholesterol (mean difference: -0.4; 95% CI: -0.6, -0.2; P < 0.001). No effects were observed for other outcome measures. CONCLUSIONS Following a MedDiet with additional dairy foods led to significant changes in markers of cardiovascular risk over 8 wk. The MedDiet supplemented with dairy may be appropriate for an improvement in cardiovascular risk factors in a population at risk of CVD. This trial was registered at anzctr.org.au as ACTRN12616000309482.

Abstract
Food cravings are common in type 2 diabetes (T2D). Higher-protein diets are effective in improving satiety but their effect on cravings is unclear. It was hypothesized that a high protein (HP) diet would provide greater reductions in cravings than an isocaloric higher-carbohydrate diet (HC). In a randomized controlled trial, 61 adults (54% males) with T2D (means ± SD: BMI 34.3 ± 5.1 kg/m2; aged 55 ± 8 years) consumed either a HP diet (mean across study: 29% protein, 34% carbohydrate, 31% fat) or an isocaloric HC diet (21%:48%:24%) for 12-weeks each of weight loss (WL) and weight maintenance (WM). The Food Craving Inventory (FCI), measuring types of foods craved and the General Food Craving Questionnaires measuring traits (G-FCQ-T) and states (G-FCQ-S) were assessed at Weeks 0, 12 and 24. Weight changes were similar between groups (means ± SEM: WL: -7.8 ± 0.6 kg, WM: -0.6 ± 0.4 kg). No group effects or group x time interactions were found for any outcome (P ≥ .07). Independent of group, all food cravings (except carbohydrates) and G-FCQ-T subscales decreased over the 24-week study (P ≤ .04) with sweets and fast food cravings, loss of control and emotional cravings reducing following WL (P ≤ .03). Obsessive preoccupation with food decreased following both phases (WL: P = .03; WM: P = .001). Weight was associated with several FCI subscales (r ≥ 0.24, P ≤ .04). In conclusion, both the HP and HC diets provided significant reductions in food cravings after similar weight losses which were maintained when weight was stabilized.
