Depression is one of the most overlooked psychiatric disorders among middle-aged and elderly men. Saffron (Crocus sativus L.) stigmas are a favorite and common spice that is used as an antidepressant, an anti-inflammatory and a sexual stimulant. This systematic review aimed to provide a comprehensive survey of the effects of saffron on depression in middle-aged and elderly men.

The authors searched Web of Science, PubMed, ProQuest, Cochrane, Science Direct, Scopus and Google Scholar databases to gather any relevant studies published from 1980 to September 2022. This review included studies that examined the relationship between depression and testosterone concentration (four studies) or saffron’s effects on testosterone and depression (six studies).

Observational research showed an association between testosterone and depression in middle-aged and elderly men. Furthermore, animal studies have found that saffron increased testosterone levels and decreased depression in males. There is evidence that testosterone may contribute to the mood. Besides its antioxidant and anti-inflammatory properties, this study proposed scientific mechanisms that saffron may also play a protective role against depression through its influence on testosterone, in middle-aged and elderly men. The general use of saffron at high doses or for prolonged periods may cause side effects; therefore, it is important to consult a health-care professional before the recommended dosage and duration of saffron supplementation, especially if a person has any underlying health conditions or is taking medications.

This study provides researchers with an additional perspective for conducting clinical trials on the use of saffron to enhance the mood of elderly men with testosterone deficiency.

Metabolic syndrome contains metabolic disorders that have association with other chronic diseases. Melatonin is a bioactive compound which is found in plants and also produced in the body. The purpose of this paper is to assess the effect of melatonin supplement on metabolic syndrome components, also leptin and adiponectin blood concentrations in patients with metabolic syndrome.

A double blind, placebo-controlled, randomized clinical trial was conducted on 70 subjects with metabolic syndrome. Participants received 6 mg/day melatonin or placebo before bedtime for 12 weeks. At the beginning and end of treatment period, blood samples were collected and biochemical parameters were measured. In addition, blood pressure and anthropometric indices were examined before and after the supplementation. Independent sample t-test was used to compare changes in metabolic syndrome components between the two study groups.

Results showed a significant reduction in waist circumference (−1.54 vs −0.04 cm; p = 0.036), systolic blood pressure (−3.52 vs 0.79 mmHg; p = 0.020), diastolic blood pressure (−1.50 vs 1.73 mmHg; p = 0.014), serum leptin concentration (−2.54 vs 0.27ng/ml; p = 0.041) and an elevation in high-density lipoprotein cholesterol (2.19 vs −0.79 mg/dl; p = 0.038) in the melatonin group compared to the placebo.

If insulin concentration had been measured, it might have revealed better interpretation of melatonin effect on fasting blood glucose.

This study showed that melatonin as a nutritional supplement improved most metabolic syndrome components and concentration of leptin in the melatonin group compared to the placebo.

In spite of the importance of food intake in weight management and preventing chronic diseases, it remains difficult to predict how anxious people change their eating behaviour in exposure to bad or good moods. The purpose of the study was to investigate the interaction effect of anxiety and different moods on food intake and blood pressure in healthy women students.

A total of 82 women university students (18-30 years) participated in the study. Subjects completed a valid anxiety questionnaire at baseline to measure trait and state anxiety scores, then they were randomly divided into two groups to watch comedy and drama movies for mood induction. After watching, some snacks were presented, and then energy intake and blood pressure were measured.

Students who suffered from severe state anxiety, consumed more energy from food when they watched a dramatic movie (p = 0.014). Subjects who suffered from moderate level of state anxiety and watched a dramatic movie experienced more systolic and diastolic blood pressure compared with subjects who suffered from moderate state anxiety but watched the comedy (p = 0.043 and p = 0.041, for systolic and diastolic blood pressure respectively). More diastolic blood pressure was shown among students who watched the drama movie and suffered from a severe level of trait anxiety (p = 0.049).

Electrocardiography and stroke volume measurement were not used.

Our findings showed blood pressure elevation in anxious people when they experienced bad feeling such as sadness, and they also consumed more energy from food. Both of these factors are related to the occurrence of chronic disorders such as cardiovascular diseases.

Post-partum depression (PPD) is a mood disorder that affects 20-40 per cent of women in their post-delivery period worldwide. The purpose of this paper is to compare dietary intakes of energy, macronutrients, cholesterol, saturated fatty acids (SFAs), mono-unsaturated fatty acids (MUFAs), poly-unsaturated fatty acids (PUFAs), some micronutrients and antioxidants in PPD patients with healthy controls.

This case-control study was conducted on 163 women in postpartum period (81 PPD and 82 non-PPD) using Edinburgh questionnaire for the diagnosis of PPD. Dietary nutrients intake was assessed using 147-item semi-quantitative food frequency questionnaire (FFQ). Portion sizes of food items were converted to grams per day. Logistic regression models were used to estimate the association between tertiles of dietary intakes with the odds ratio (OR) of PPD.

According to the fully adjusted model, highest tertile compared to lowest tertile dietary intake of SFAs [OR = 0.01; 95 per cent confidence interval (CI) = 0.00, 0.01, p = 0.001], MUFAs (OR = 0.01; 95 per cent CI = 0.00, 0.02, p < 0.001), total fats (OR = 0.01; 95 per cent CI =0.00, 0.01, p < 0.001) and cholesterol (OR = 0.06 ; 95 per cent CI = 0.01, 0.08, p < 0.001), thiamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), riboflavin (OR = 0.10; 95 per cent CI = 0.02, 0.39, p < 0.001), pyridoxine (OR = 0.03; 95 per cent CI =0.01, 0.32, p < 0.001), folate (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), cobalamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001) , selenium (OR = 0.79 ; 95 per cent CI =1.36, 3.32, p < 0.001), iron (OR =0.68; 95 per cent CI = 0.24, 0.94, p < 0.001) and iodine (OR = 0.36; 95 per cent CI =1.10, 1.38, p < 0.001) had a protective effect on the incidence of PPD. Furthermore, higher intake of vitamin A and beta-cryptoxanthin can increase the incidence of PPD (OR =114.29; 95 per cent CI =17.85, 118.12, p < 0.001) and (OR = 4.85; 95 per cent CI = 1.49, 15.69, p = 0.015), respectively.

PPD may have destructive effects on the relationship between mother and infant. Results of previous studies demonstrated nutrients are required for the synthesis of neurotransmitters and have biochemical role in the nervous system.
