Objective: Recent studies have shown that inflammatory diseases can be influenced by nutritional factors. For this reason, this study was designed to evaluate the food intake of patients with periodontal disease in comparison to healthy subjects using a 7-day food record (7-DFR). Method and Materials: The study population consisted of 42 patients with chronic periodontitis and 38 healthy subjects (controls). Periodontitis was diagnosed by using the Plaque Index, Sulcus Bleeding Index, and measurement of probing depth. All participants completed a 7-DFR, which was analyzed with DGE-PC Professional 2.7. To confirm the nutritional analysis, the vitamin C plasma level of each participant was measured. Additionally, the oral discomfort of patients with periodontal disease was ascertained by using an additional questionnaire. Results: Analysis of the 7-DFR revealed that patients with periodontitis had significantly lower intake rates of vitamin C, folic acid, magnesium, and fiber than those of healthy controls. The mean vitamin C plasma levels were significantly lower in patients with periodontitis (0.63 mg/dL) compared with healthy control subjects (1.13 mg/dL, P < .05). Evaluation of the questionnaire showed that approximately 50% of patients experienced discomfort while eating. Conclusion: The present study shows that patients with periodontitis have a reduced intake of vitamin C, folic acid, magnesium, and fiber compared with healthy subjects. This is possibly an outcome of oral discomfort during mastication. To avoid an insufficient nutrient supply for a patient with periodontal disease, the patient's choice of foods should be closely monitored. HubMed – eating

Neural systems that identify and respond to salient stimuli are critical for survival in a complex and changing environment. In addition, interindividual differences, including genetic variation and hormonal and metabolic status likely influence the behavioral strategies and neuronal responses to environmental challenges. Here, we examined the relationship between leptin allelic variation and plasma leptin levels with DAD2/3R availability in vivo as measured with [(11)C]raclopride PET at baseline and during a standardized pain stress challenge. Allelic variation in the leptin gene was associated with varying levels of dopamine release in response to the pain stressor, but not with baseline D2/3 receptor availability. Circulating leptin was also positively associated with stress-induced dopamine release. These results show that leptin serves as a regulator of neuronal function in humans and provides an etiological mechanism for differences in dopamine neurotransmission in response to salient stimuli as related to metabolic function. The capacity for leptin to influence stress-induced dopaminergic function is of importance for pathological states where dopamine is thought to play an integral role, such as mood, substance-use disorders, eating disorders, and obesity.

Background: The prevalence of overweight individuals has increased in recent years. Moreover, the importance of a healthy diet is associated with the practice of physical activity and attempt to verify the achievement of physical exercise influences on food choice. However, it relationship between food intake and physical activity have not been studied. Aim: To evaluate if the period in which the trainings are conducted, morning and nocturne, interfere qualitatively and quantitatively in food consumption as well as verify possible associations between anthropometric profiles and dietary habits. Methods: We collected data from 33 adult volunteers, between men and women, practitioners of bodybuilding. Results: A total of 33 volunteers were interviewed (18 (54.5%) were men and 15 (45.5%) were women). Regarding anthropometric data, it turns out that that the volunteers of the two periods had similar characteristics, differentiating only weight. The consumption of nutritional supplements was observed in 30.77% of the practitioners in the morning period vs. 35% for the nocturne. Considering macronutrient intake, there was a significant difference in the consumption of protein between the periods. The consumption during nocturne period was greater (126 ± 5% of the daily requirement) than the morning period (115.7 ± 2%). As for micro-nutrients, calcium intake was greater among men when compared to women. There was a positive correlation between the BMI, and arm circumference for practitioners of the morning period. Conclusion: This study show that the practitioners who train in the morning have quietly better eating habits than those in the nocturne period, however both are inappropriate.
