Background: Mild cognitive decline, a common issue in aging, affects memory, learning, and attention. Nutrition can influence cognition, and research indicates that Ocimum sp. (holy basil and sweet basil) leaf extracts may enhance cognition in rodents and humans. However, these studies do not address whether these benefits extend to fresh or dry leaves consumed in typical human diets, along with physiological aging. Aim: To investigate the effects of sweet basil supplementation on cognition in mature and aged female mice. Methods: Female C57bl mice were divided into four groups: 8-month-old mature adults and 18-month-old aged adults, each receiving either a control or supplemented diet. The supplemented diet included a mix of standard chow and fresh basil leaves, administered for 2-8 months. Cognitive and behavioral assessments were conducted using the novel object recognition (NOR), Morris water maze (MWM), and elevated plus maze (EPM) tasks, focusing on memory, learning, and anxiety. Results: No cognitive improvement was observed in mature mice. However, aged mice receiving long-term basil supplementation showed enhanced discrimination in NOR and stayed closer to the absent platform in MWM compared to nonsupplemented controls. While aging mice exhibited reduced anxiety-like behavior in EPM, basil supplementation prevented this reduction. Conclusion: Basil supplementation appears beneficial in elderly mice, potentially preventing age-related cognitive decline and behavioral changes. These findings support the benefits of basil consumption in cognition and underscore its potential role in promoting healthy aging. Incorporating basil into the diet at a younger age may preserve memory and mitigate behavioral changes as individuals age.

Objective: To examine the association between habitual intake of milk and dairy products and insomnia. Design: Cross-sectional study by using cohort study data among 60,633 participants (22,721 men and 37,912 women) aged 20-74 years in eastern Japan. The data of milk and dairy products intake, sleep status and other lifestyle habits were collected by self-administered questionnaires. The question about milk and dairy products included whole milk, low-fat milk, cheese, yogurt, and lactic acid bacteria beverages, and were assessed by frequency (< 1 time/week, 1-2 times/week, 3-6 times/ week, and ≥ 1 time/day). Sleep status was scored with the Athens Insomnia Scale. Results: Logistic regression analysis showed that adjusted odds ratio (OR) and 95% confidence interval (95% CI) for insomnia were statistically significantly lower for whole milk intake > 1 time/day compared to < 1 time/week in all (OR: 0.91; 95% CI: 0.86-0.96; P = 0.001). The similar results were shown for women (OR: 0.90; 95% CI: 0.85-0.97; P = 0.002), not for men. In contrast, the adjusted odds for insomnia were high in the group that had frequencies of 3-6 times/week of lactic acid bacteria beverages compared to <1 time/week (OR: 1.20, 95% CI: 1.11-1.29; P < 0.001 in all; OR: 1.36; 95% CI: 1.19-1.55; P < 0.001 in men; OR: 1.13; 95% CI: 1.03-1.24; P = 0.009 in women). Conclusions: This cross-sectional study of Japanese populations showed a tendency for no insomniacs to consume whole milk more frequently.

Background: Human milk provided by healthy, well-nourished mothers represents the best food available for infants. Human milk is species-specific and recommended as the sole source of nutrition for the first 6 months of life and is an important food source until the infants reach 2 years of life. Unlike infant formula, which has a standardized composition, human milk composition varies among and within women. Aim: While many studies of human milk composition have been conducted, none have been done among the Orang Asli people in Malaysia. Hence, this study protocol is designed to determine the human milk composition of the Orang Asli in Peninsular Malaysia and how the transition of culture, nutrition, and different lifestyle experiences will affect the nutrient content of their milk. Methods: Quantitative (interviewer-administered questionnaire) and qualitative (focus group discussion) approaches will be employed in this study and in addition, laboratory works will also be carried out to analyze the nutrient composition of the milk samples collected from various Orang Asli subethnic groups in Peninsular Malaysia. Conclusion: Standardized, multipopulation studies of human milk composition are sorely needed to create a rigorous, comprehensive reference inclusive of nutrients and other factors. The establishment of any dietary parameters positively affecting the nutrient content of human milk may help design healthcare strategies in Malaysia to improve the quality of human milk and therefore the infants' health status.

Background: Periodontitis presents as a chronic inflammatory disease that affects the gingival tissues and structures surrounding the tooth. However, the existing approaches for periodontitis do not allow complete control of the disease. In this regard, an active search is being carried out both in preclinical and clinical studies for new approaches based, among other things, on nutraceuticals. Aim: This systematic review aimed to summarize and systematize data from preclinical studies on the effects of the use of polyunsaturated omega-3 fatty acids in experimentally induced periodontitis. Methods: A systematic search for research articles was performed using electronic scientific databases. Only original in vivo experimental studies investigating the use of omega-3 polyunsaturated fatty acids in experimentally induced periodontitis were included. Quality and risk of bias assessment (Systematic Review Centre for Laboratory Animal Experimentation) and quality of evidence assessment (using the modified Grading of Recommendations Assessment, Development and Evaluation approach) were performed. Results: Nineteen studies were included in this systematic review. It has been shown that omega-3 polyunsaturated fatty acids may decrease the progression of periodontitis with amelioration of alveolar bone loss along with decreased pro-inflammatory response and inhibition of osteoclasts. Despite the promising results, most of the analyzed studies were characterized by low to moderate quality and a significant risk of bias. Conclusion: Based on the retrieved data, the possibility of extrapolating the obtained results to humans is limited, indicating the need for additional studies to elucidate the key patterns and mechanisms of action of omega-3 polyunsaturated fatty acids and their endogenous metabolites in experimentally induced periodontitis.

Background: Food insecurity means having limited or uncertain access to an adequate, nutritious, and safe diet. Rates among US college students range from 10% to 75%, and the problem is associated with mental and physical health disorders and unfavorable academic outcomes. Aims: This study examined the associations between the food security status of sophomores attending a university in the Southeastern US and their need for social support, food access behaviors, and budgeting knowledge. Methods: Data were collected during the spring 2019 semester using an online questionnaire. Food security was measured using the United States Department of Agriculture (USDA) Food Security Survey, and the independent variables were measured from scales grounded in pertinent literature. Descriptive and inferential procedures were applied, and significance was p ≤ 0.05. Results: Participants were 222 sophomores (75% female and 85% white). Food insecurity was 46.4%, and significant predictors (p < 0.001) were need for social support accessing food and the requested educational activity "learning how to make a budget." Mean budgeting knowledge scores of food secure and insecure students, respectively, were 11.5 ± 1.8 versus 11.1 ± 2.4 (p = 0.42) out of 14 points. Food access behaviors used "sometimes" or "often" by food secure and insecure sophomores included buying food on sale and buying the store brand of a food, while creating a budget that includes food purchases and getting free food from food pantries were "seldom" or "never" used. Conclusions: Food insecurity was high. Learning activities, such as budgeting education, should be tested as strategies for decreasing food insecurity.

Background: Experiential dimensions of Mindful Eating Practices are scarce in the literature. Aim: The study focuses on thirteen individuals with clinical obesity and nine post-bariatric surgery patients who engaged in MERP over three months. Methods: The present research utilized Interpretative Phenomenological Analysis (IPA) as the analytical framework of interviews. Results: Four overarching themes emerged from the analysis: 1. "Enhanced Awareness of Eating": This theme underscores MERP's central emphasis on cultivating heightened mindfulness during food consumption, highlighting the importance of being present at the moment while eating; 2. "Facilitating the Transition to Healthier Eating Habits": This theme explores how MERP influences participants' dietary choices, eating pace, portion control, and overall enjoyment of meals. It reveals that MERP encourages individuals to reflect on their eating habits and transition towards healthier choices; 3. "Diverse Perspectives on Satisfaction with MERP": Within the context of MERP, participants held varied interpretations of satisfaction. Some encountered practical limitations or engaged in reflective self-examination, while others found sensory satisfaction, enhancing their overall eating experiences; and 4. "Utilization and Development of MERP": This theme delves into participants' patterns of using MERP. It reveals a tendency to avoid MERP in the morning, a gradual decline in its usage over time, and a preference for an electronic version of the practice. Conclusion: The MERP shows promise in improving overall eating habits by enhancing enjoyment of food, increasing awareness of body cues, promoting healthier choices, and encouraging mindful eating practices. These findings provide valuable insights for future research and the refinement of clinical tools aimed at effective weight management and the promotion of sustainable healthy eating practices by effectively addressing a significant gap in our understanding of the experiential facets of eating practices.

Background: The prevalence of central obesity is increasing in many regions, including low- and middle-income countries. It has been identified that a poor diet has become a significant risk factor for central obesity. However, the relationship between diet and the prevalence of central obesity among rural and urban communities remains unclear in low- and middle-income countries. Aim: This study aimed to analyze the association of food consumption with central obesity among middle-aged adults (45-59 years) in urban and rural areas in Indonesia. Methods: This was a cross-sectional study using secondary data from a national survey (Indonesia Basic Health Survey) in Indonesia in 2018. A total of 154,449 subjects were analyzed for the study. We used the International Diabetes Federation to define central obesity. Food consumption was measured using a validated food frequency questionnaire. Multivariable logistic regression was used to explore the association between food consumption and central obesity. Results: Frequent consumption of refined desserts, fried food, processed food, and inadequate consumption of fruit was significantly associated with central obesity in urban and rural areas (p < 0.05). In contrast, frequent consumption of seasoning and inadequate consumption of vegetables was significantly associated with central obesity only in rural areas (p < 0.05). Conclusion: Food consumption has a different association with central obesity risk in rural and urban areas in Indonesia.

Background: Stroke presents a significant global health challenge. Despite its potential for cardiovascular protection, the role of vitamin C (VTMC) in stroke risk remains contentious. Aim: This study aimed to assess VTMC deficiency in stroke patients and its association with stroke risk. Methods: We analyzed data from 13,339 adults aged 20 and above in the National Health and Nutrition Examination Survey (NHANES) between 2003 and 2018, excluding those with missing serum VTMC and stroke status. We assessed the VTMC deficiency (<11.4 µmol/L) and stroke incidence association using multivariate weighted logistic regression, adjusting for demographics, BMI, medical history, smoking, and dietary VTMC intake. Results: Stroke rates in the NHANES cycles 2003-2006 and 2017-2018 were 2.8% (95% CI [2.3-3.4]) and 3.3% (95% CI [2.7-4.2]), respectively. VTMC deficiency was more common in individuals with a history of stroke, with rates of 3.6% (95% CI [2.2-5.8]) and 5.3% (95% CI [3-9.1]) compared to 2.7% (95% CI [2.3-3.3]) and 3.2% (95% CI [2.5-4.1]) in the nonstroke population. Nevertheless, VTMC deficiency was distinctly prevalent across diverse demographic and health-related subgroups. Multivariate analyses invalidated any statistically significant association between VTMC deficiency and stroke risk across all employed analytical models within both time intervals. Conclusions: Our study does not support a link between VTMC deficiency and increased stroke risk in U.S. adults. Substantial uncertainties persist regarding the use of VTMC for stroke-related oxidative stress, dosage, and delivery methods, requiring further clinical trials. Healthcare providers should carefully consider its prevalence in specific subgroups.

Background: The presence of others' eyes has been shown to influence food evaluation. Aim: The purpose of the present study was to investigate whether the presence of others' gaze would lead to a reduction in food intake in accordance with social norms. Methods: In this study, we enlisted the participation of 30 volunteers. During the experiment, participants had the opportunity to consume noodles freely as much as they wanted while viewing one of the three images: (1) featuring a person with open eyes (Open condition), (2) depicting a person with closed eyes (Closed condition), and (3) displaying an image devoid of a person (None condition). Results: Food consumption in each condition was 460.00 ± 20.97 g for the Open condition, 515.57 ± 22.97 g in the Closed condition, and 505.03 ± 21.05 g in None condition. The condition had a statistically significant main effect (F = 4.656, p = .013). The Least-Square means analysis revealed that food consumption in the Open condition was significantly lower than in the other two conditions (Closed and None conditions) (Closed - Open: t = 2.872 [95% CI: 16.844-94.289], p = .006; None - Open: t = 2.328 [95% CI: 6.311-83.756], p = .023). There was no significant difference in food consumption between the Closed and None conditions (Closed - None: t = 0.545 [95% CI: -28.189-49.256], p = .588). Conclusion: The results of the present study suggest that the presence of others' eyes would reduce food intake in accordance with social norms.

Background: Low protein intake and physical inactivity are factors that associated with muscle deterioration and poor physical performance among older adults.

Aim: To assess the association between dietary protein intake and physical fitness tests among older adults with pre-sarcopenia and sarcopenia.

Methods: A total of 110 older adults were recruited through a convenience sampling method. Data including sociodemography, anthropometry, body composition, medical history, and dietary protein intake were obtained through the interview-administered method.

Results: Most of the subjects have low household income (2), whereas those with pre-sarcopenia had a slightly higher Body Mass Index (BMI) (± 27.30 kg/m²). Both men and women did not meet the dietary protein requirement (± 43.86 g/ day) based on the Recommended Nutrient Intake (RNI) of 2017. Moreover, both pre-sarcopenic and sarcopenic subjects have reduced functional ability. Although no significant differences were found in the Short Physical Performance Battery (SPPB) score, those with sarcopenia had poorer physical performance than those with pre-sarcopenia (82.1% versus 69.5%). Apart from that, there was a significant association between the 2-min step test (2MST) and dietary protein intake among those with pre-sarcopenia (r-value = 0.252).

Conclusion: In conclusion, lifestyle interventions among older adults are important, including ensuring adequate protein intake and encouraging appropriate physical activity to enhance muscle mass, strength, and performance to improve their daily life efficiency and quality of life.
