Sex Differences in the Efficacy of Mediterranean Diet Treatment: A Nutrigenomics Pilot Study.

The Mediterranean diet (MedD) has been shown to have beneficial effects on health, well-being, and mental status. It potentially modulates gene expressions linked to oxidative stress, contributing to its beneficial effects on overall health. The aim of this study was to assess the effects of MedD treatment in healthy human volunteers on the expression of ten genes related to oxidative stress and inflammation in women and men. Of 30 enrolled subjects, 17 were eligible, 10 women and 7 men. All of them received the same MedD treatment. Before and after 8 weeks of MedD treatment, an evaluation of body composition, blood tests, and anthropometric and clinical parameters was performed. Furthermore, 10 genes were amplified and analyzed. The study showed significant differences between females and males in body composition and biochemical parameters before and after MedD treatment. Significant differences between females and males in Resistance Force (p < 0.009) and Diastolic Blood Pressure (p < 0.04) before MedD treatment, and in High-Density Lipoprotein (p < 0.02) after MedD treatment, were observed. Moreover, a significant upregulation of Apolipoprotein E and Angiotensin I-Converting Enzyme in females has been shown. Sex differences impact MedD treatment response, and influence the genetic expression of genes related to oxidative stress; our findings may help to personalize diet therapy and contribute to overall health and well-being.

Exploring the Sustainable Benefits of Adherence to the Mediterranean Diet during the COVID-19 Pandemic in Italy.

This study aimed to identify adherence to the Mediterranean diet (MedDiet) and its effect on health and environmental and socioeconomic sustainability during the COVID-19 pandemic among a sample of the Italian population. Notably, it intended to assess the effect of adherence to the MedDiet on ecological footprints and food expenditure. A survey was conducted from the 5th to the 24th of April 2020 on Google Forms. The MEDAS questionnaire was used to determine the level of adherence to the MedDiet. The carbon footprint (CO2), water footprint (H2O), and food cost were calculated. In total, 3353 participants completed the questionnaire, ranging from 18 to 86 years old. A statistically significant difference was observed in the CO2 and H2O among BMI groups (p < 0.001). The low- and medium-MEDAS groups showed higher CO2 (p < 0.001). The food cost (EUR/week) resulted in statistically significant differences among the MEDAS groups. The CO2 results were significantly lower in organic-market buyers compared to non-organic-market buyers (p < 0.001). Public health must promote awareness of how adhering to a healthy lifestyle and making appropriate food choices can positively impact our health and social and economic well-being.

Dietary ω-3 intake for the treatment of morning headache: A randomized controlled trial.

Morning headache (MH) is a frequent condition with a not fully explained pathogenesis. During the past years, several studies have been performed to identify a better diet therapy to reduce the frequency and intensity of headaches. Our study aims to determine if an adequate omega-3 (ω-3) intake in a Modified Mediterranean Diet (MMD) can improve the frequency and intensity of MH and, subsequently, the quality of life. Of the 150 enrolled subjects, 95 met the inclusion criteria (63.3%). Patients were included in the study and randomized into two groups: group A following MMD A and group B following MMD B. The MMD A group was designed to arise at least a 1.5:1 ω-6/ω-3 ratio; the MMD B group was designed to derive at least a 4:1 ω-6/ω-3 ratio. Eighty-four subjects completed the 6 weeks intervention (56%). After 6 weeks (t1), group A showed a significant reduction in both Headache Impact Test-6 and Visual Analog Scale scores (p < 0.001, p < 0.001, respectively). During dietary treatment, group A progressively dismissed ketoprofen-based pharmacological treatment (p = 0.002) from baseline to t1. Furthermore, a decrease in the platelet-to-lymphocyte ratio and neutrophil-to-lymphocyte ratio at t1 in group A (p = 0.02) was observed compared to group B. Concluding, this study provides evidence of a positive impact of ω-3-enriched MMD regimen on the inflammatory status and MH.

The association between serum vitamin D and mood disorders in a cohort of lipedema patients.

OBJECTIVES: The association between serum Vitamin D (Vit. D) and mood disorders in lipedema patients has not been investigated. Therefore, the main aim of this study is to investigate the correlation between serum Vit. D, depression and anxiety risk. METHODS: A cross-sectional cohort of lipedema patients were investigated by collecting the clinical and demographic data. The Hamilton Depression Scale (HAM-D) and the Hamilton of Anxiety Scale (HAM-A) were used to evaluating the risk of depression and anxiety. Serum concentrations of Vit. D were measured. The association between Vit. D levels and both HAM-A and HAM-D scores were statistically examined by bivariate and partial correlations. RESULTS: Forty lipedema patients were enrolled in this study. Around two-thirds of them had a higher depression or anxiety risk, and 77.5% were under the normal serum Vit. D levels. A significant and inverse correlation was observed between serum Vit. D levels and both HAM-D (r=-0.661, p<0.001), and HAM-A (r=-0.496, p=0.001) scores. This strong association was sustained after the statistical model adjusted for the main potential confounding factors (age, body mass index (BMI), disease duration, and lipedema stages). Additionally, serum Vit. D correlated significantly and inversely with BMI (r=-0.647, p<0.001). Moreover, BMI significantly correlated with HAM-D: r=0.560, p<0.001, and HAM-A: r=0.511, p=0.00. CONCLUSIONS: This study suggests a strong correlation between Vit. D levels, depression scores, and anxiety scores in lipedema patients. Our results also demonstrate a strong and direct relationship between BMI, Vit. D levels, depression, and anxiety.

Potential Effects of a Modified Mediterranean Diet on Body Composition in Lipoedema.

Lipoedema is a subcutaneous adipose tissue disease characterized by the increase in the amount and structure of fat mass (FM) in specific areas, causing pain and discomfort. 95% of patients fail to lose weight in the lipoedema areas. The study was conducted to evaluate body composition and general health status modification in a group of lipoedema patients (LIPPY) and a control group (CTRL) after four weeks of a modified Mediterranean diet therapy (mMeD). A total of 29 subjects were included in the data analysis, divided in two groups: 14 LIPPY and 15 CTRL. After the mMeD, both groups significantly decreased their weight and body mass index; the CTRL also showed a reduction of all the circumferences and all FM's compartments. LIPPY showed a decrease of FM in upper and lower limbs. No significant differences in Δ% between the groups were observed for the lean mass (LM). In LIPPY, an increase in the patients' ability to perform various daily physical activities related to the loss of arms' and legs' fat was observed. According to the European Quality of Life scale, the possibility for LIPPY subjects to perform simple daily activities with less fatigue, pain and anxiety is highlighted. Further long-term studies are recommended to confirm the mMeD as a good strategy for Lipoedema treatment.

Psychological Aspects and Eating Habits during COVID-19 Home Confinement: Results of EHLC-COVID-19 Italian Online Survey.

The COVID-19 pandemic has had a huge impact on the population with consequences on lifestyles. The aim of the study was to analyse the relationship between eating habits, mental and emotional mood. A survey was conducted online during social isolation, from 24 April to 18 May 2020, among the Italian population. A total of 602 interviewees were included in the data analysis. A high percentage of respondents experienced a depressed mood, anxious feelings, hypochondria and insomnia (61.3%, 70.4%, 46.2% and 52.2%). Almost half of the respondents felt anxious due to the fact of their eating habits, consumed comfort food and were inclined to increase food intake to feel better. Age was inversely related to dietary control (OR = 0.971, p = 0.005). Females were more anxious and disposed to comfort food than males (p < 0.001; p < 0.001). A strength of our study was represented by the fact that the survey was conducted quickly during the most critical period of the Italian epidemic lockdown. As the COVID-19 pandemic is still ongoing, our data need to be confirmed and investigated in the future with larger population studies.
