(1) Background: Walnut consumption has been associated with having a positive effect on controlling and/or reducing the co-morbidities associated with cardiovascular disease (CVD). The effects of consuming walnuts of Portuguese origin on risk factors related to CVD were evaluated by measuring glucose, urea, TC, HDL-C, LDL-C, TG, AST, and ALT levels, anthropometric profiles, and blood pressure. (2) Methods: This trial study involved 24 volunteers, both female (n = 15) and male (n = 9), from Fernando Pessoa University, Porto. It consisted of a daily intake of 25 g of walnut kernels over a period of 45 days. Before and after intake, biochemical parameters, BMI and BP were measured. (3) Results: Despite the intake of nuts revealing a reduction in mean values of most of the parameters assessed, a significant drop was only observed in AST (p = 0.04).There was also a significant reduction in the mean values for Glu (p = 0.01), UR (p = 0.01) and HDL-C (p = 0.02) for women but not for men. (4) Conclusions: The dose and the period of intake were not effective in lowering the lipid profile but may have had a protective effect on liver function. The benefits were greater in women than in men. Full article

The popularity of vegetarian and vegan diets is growing due to increased awareness of the environmental and health benefits of such diets. However, despite the consumption of meatless diets being associated with decreased risk of chronic diseases and mortality, followers of these diets are prone to certain nutritional inadequacies, which could limit health benefits. The main nutrients of concern are vitamin B12, vitamin D, iodine, selenium, calcium, and iron. It is essential for all those following vegetarian and vegan diets to implement vitamin B12 supplementation. To prevent vitamin B12 deficiency, adults should take one oral dose of 50–100 μg cyanocobalamin daily or 2000 μg weekly divided into two oral cyanocobalamin doses. Iodine supplementation is essential for pregnant and breastfeeding women and is recommended for vegetarians and vegans who are unable to access sea vegetables or iodine-fortified foods. The recommended dose of iodine supplement for adults is 150 μg daily. Selenium supplementation should be reserved for individuals with clinical evidence of deficiency due to concerns of adverse effects on lipid profiles and type 2 diabetes risk. It is recommended that vegetarian and vegan adults should supplement 4000 International Units (IU)/d of oral vitamin D to prevent deficiency as sunlight exposure is unreliable due to a range of lifestyle and environmental factors. This recommendation also applies to omnivores. As a precaution, those wishing to transition to a more plant-based diet should consider how they will substitute the nutrition they currently obtain from animal-based foods with plant-based sources or appropriate supplementation.

This study aimed to explore the dietetic treatment experiences of individuals with high eating disorder (ED) symptomatology attending a metabolic and bariatric clinic. An exploratory mixed methods cross-sectional study was conducted. Eighteen participants completed the survey, which included an adapted version of the Eating Disorders Treatment Experience Survey (EDTES), the Eating Disorder Examination Questionnaire Short (EDE-QS), and quantitative and qualitative questions relating to the roles and helpfulness of a dietitian in treatment. Data regarding the most and least helpful dietitians were collected. Differences between groups were tested with the Wilcoxon signed ranks test. A reflexive thematic analysis was used to analyse open-ended responses. The mean EDE-QS score reported by participants was 20.9 (SD = 6.0). The dietitians who were perceived as the most helpful were those who took into consideration an individual’s treatment preferences and choices (Z = −1.96, p = 0.05). Three themes were constructed: (1) nutrition knowledge and skills, (2) person-centred care, and (3) roles of the multidisciplinary team. Although further research is required, our findings suggest that the role of a dietitian in this setting may extend beyond weight-loss advice, and with additional training, could include individualised and collaborative supportive care that overlaps with ED treatment.

The demand for low-sodium products is growing worldwide and is compelled by the growing number of related illnesses. However, the quality of these products could be improved, likened to products produced with common salt (NaCL), because the replacement of sodium compromises the flavor of the product. Reducing sodium salts also poses an essential challenge for the meat industry, since sodium chloride (NaCl) fulfills essential technological functions. High sodium consumption has harmful health implications for cardiovascular and hypertension disorders. As a result, this study aimed to analyze the effect of KCl with Glycine and AMP on the physicochemical and sensory characteristics, purchase intent, and consumer perception of roasted chicken. NaCl/KCl replacement levels (0%, 25%, 50%, 75%, and 100%) were established, and consumer perception, liking, emotions, and purchase intent were evaluated. The different KCl levels, except for firmness, did not impact the physicochemical attributes. Even though higher replacement levels of KCl (75–100%) impacted chicken tenderness, it had no notable impact on panelists’ liking scores and purchase intent. Health claims about the sodium content in roasted chicken have also been shown to significantly increase purchase intent, based on enhancing consumer’s emotional responses. Regarding emotional responses, feelings of being unsafe and worried decreased their scores among the highest KCl replacement levels (75% and 100%). Positive emotional responses (feeling satisfied and pleased) were decisive consumer purchase intent predictors. Full article

Evidence has shown that one of the most prevalent chronic conditions in postmenopausal women is osteoporosis. Despite the development of some medications, there are still safety and adherence concerns, and, thus, attention has been placed on understanding modifiable risk factors for bone loss. This study aimed to examine the differences in various sociodemographic and body composition factors, physical activity components, and nutrient and food group intake levels among peri- and early postmenopausal women with whole-body bone mineral density (BMD) Z-scores greater than and less than zero. This cross-sectional study utilized baseline data obtained from 45 peri- and early postmenopausal women aged 45–60 years old who participated in a 6-month three-arm, randomized, double-blind, placebo-controlled clinical trial that evaluated the effects of blackcurrant supplementation on bone metabolism. Anthropometric data, BMD values obtained via DXA scans, and self-reported demographic, health, dietary, and physical activity data were collected at baseline. Overall, participants with whole-body BMD Z-scores greater than zero had higher body mass indexes (BMIs), lean mass, fat mass, android fat percentages, ratios of trunk fat mass to limb fat mass, resting metabolic rates, relative skeletal muscle indexes, total and occupational physical activity, alcohol intakes, trans fatty acid intakes, and adequacy of potassium intake, but lower adequacy of vitamin E (p < 0.05). In addition, total calorie intake was positively correlated with added sugar, vitamin E, potassium, alcohol, trans fatty acids, calcium, and vitamin D intakes (p < 0.05); whole-body BMD was positively correlated with added sugars (p < 0.05); vitamin D intake was positively correlated with vitamin E, potassium, trans fatty acid, and calcium intakes (p < 0.05); and calcium intake was positively correlated with added sugar, vitamin E, potassium, and trans fatty acid intakes (p < 0.05). These findings suggest that numerous body composition factors, components of physical activity, and dietary factors are related to bone health in adult women in the menopause transition.

Tsalafouti cheese, a traditional Greek spreadable cheese, has experienced remarkable popularity over the last decade due to the strong dairy production heritage links that it presents, alongside the special nutritional and sensory attributes that it holds. The aim of this study was to chemically characterize the Greek cheese Tsalafouti, with a special focus on its fatty acid profile and the potential nutritional effect it may have. Standard methods were used to assess the physicochemical profile of Tsalafouti cheese, while a fatty acid profile was determined using gas chromatography. The analysis revealed average values, including a pH of 3.94, moisture content of 75.05%, protein content of 8.86%, and fat content of 11.3%. The fatty acid profile highlighted the predominance of health-important fatty acids, such as oleic acid, known for its well-established health benefits. Additionally, the health lipid indices of Tsalafouti were assessed by calculating the atherogenicity index (IA), the thrombogenicity index (IT), the ratio of hypocholesterolemic to hypercholesterolemic fatty acids (HH), the health-promoting index (HPI), and the PUFA-n-6/PUFA-n-3 ratio. The values of these indices indicate the quality concerning proatherogenicity, prothrombogenicity, and the risk of cardiovascular issues. Notably, all the above health indicators are consistent with known health effects. Importantly, the ratio of ω6/ω3 fatty acids aligns with the nutritional recommendations of the World Health Organization. Based on these results, Tsalafouti cheese emerges as a low-fat product and source of protein with potential functional properties, distinguishing itself from other cheeses in the market.

Lean bodybuilder athletes may encounter challenges in adapting their eating habits during ad libitum refeed, either intuitively or consciously. Aims: This paper investigates whether there is a relationship between adaptive eating and energy intake coping strategies in a refeed model for bodybuilders. Methods: Fourteen male bodybuilders (29.6 ± 3.1 years; 85.6 ± 6.8 kg, ≥6 competitions) completed a 4-week regimen consisting of 5 days of energy restriction followed by 2 days of refeed. Dietary assessment, body composition (ultrasound), recovery stress questionnaire (REST-Q) and Brunel mood scale (BRUMS) were utilized pre- and post-regimen. Coping function questionnaire (CFQ), mindful eating scale version 2 (MES 2) and the intuitive eating scale-2 (IES-2) were evaluated at the 4th week. Results: Compared to the initial values, the refeed day resulted in a daily caloric increase of 44% compared to the average energy intake on the energy restriction days, culminating in a weekly calorie deficit of 27% and a drop in body mass of 3.1 ± 1.4%. Most participants showed reduced body fat and preserved or gained lean mass. The energy consumption during the refeed maintained an inverse relationship with the perception of satiety (r = −0.9; p < 0.01), the IES 2 total scores (r = −0.82; p < 0.01), as well as the confidence in hunger and satiety cues (r = −0.62; p = 0.02) and congruence in food–body choice dimensions (r = −0.56; p = 0.04). Emotional coping maintained an inverse relationship with the IES 2 total scores (r = 0.54; p < 0.05) and an inverse relationship with energy intake during refeed (r = −0.42; p < 0.05). Conclusion: The results suggest that a heightened perception of internal hunger and satiety signals and higher scores in intuitive eating may contribute to adequate energy intake, even when high scores of emotional coping are present.

The aim of this paper is to investigate associations between the time spent by parents preparing dinner and children’s consumption of made-from-scratch meals. We developed a cross-sectional study with 595 parent–child dyads from São Paulo, Brazil. Data were collected via telephone interviews: time spent preparing dinner and socio-demographic characteristics were obtained using a questionnaire, while food consumption was recorded via dietary recall. Crude and adjusted regression analyses were used to test associations between time spent preparing dinner and the contribution of made-from-scratch meals to children’s dinner energy intake. Parents (93.1% woman, 60.5% aged 31–41, 62.2% white, 88.4% married, 71.2% employed, 50.0% ≥ 12 years of education) spent an average of 108- and 112-min preparing dinner on weekdays and weekends, respectively. Spending more than two hours/day was positively associated with the consumption of made-from-scratch meals (β = 4.4; p = 0.035). When parents spend more time preparing dinner, their children consume more made-from-scratch meals. Given that cooking from scratch is considered healthier but takes more time, it is important that policies and interventions aimed at promoting healthier meals among children/families and avoiding overburdening women with domestic tasks are accompanied by recommendations that focus on promoting an equitable division of food work among families.

Background and aim: Variation in practice has been observed among the prescribed diets for inpatients with acute, uncomplicated diverticulitis. This study aimed to observe outcomes (length of stay (LOS), re-presentations, and gastrointestinal symptoms) for acute, uncomplicated diverticulitis inpatients prescribed restricted or liberalised diets during usual care. Methods: Adult inpatients with acute, uncomplicated diverticulitis were prospectively enrolled from 2017 to 2019. Demographics, clinical data, and prescribed diets were collected from medical records. Patients were categorised as having restricted or liberalised diets. Primary outcomes were LOS, re-presentations related to diverticulitis, and gastrointestinal symptoms, collected from medical records and patient surveys. Descriptive statistics were used to characterise all variables. Adjusted regression analysis was used to determine the effect of diet prescription on primary outcomes. Results: Of the 81 included patients, 47% were prescribed restricted diets, and 53% were prescribed liberalised diets. Patients prescribed restricted diets had greater LOS (median 4.0 (IQR: 3.5–5.1) vs. 2.8 (IQR: 2.2–3.8) days, p < 0.001) and were more likely to re-present due to diverticulitis at six months (OR 8.1, 95% CI 1.3–51.0, p = 0.025) in adjusted models. No difference in gastrointestinal symptoms was observed 30-days post-admission. Conclusion: In patients hospitalised with uncomplicated diverticulitis, restricted diets may be associated with longer LOS and increased odds of re-presentation at 6 months compared to liberalised diets. No differences in post-discharge gastrointestinal symptoms were observed between restricted versus liberalised diets. Randomised controlled trials are needed to confirm the causal role of inpatient diet prescription on clinical outcomes, healthcare utilisation, and patient experience.

In the Greek regions of Agrafa and Tzoumerka, Tsalafouti, a traditional spreadable cheese made from goat’s and sheep’s milk is produced. This product has emerged in recent years as a result of the campaign to acquire Geographical Indication. This study aimed to assess the biopeptide profile of Tsalafouti cheese in order to highlight its nutritional value. Using HPLC-MS, bioactive peptides in Tsalafouti cheese samples were identified and classified according to their bioactivity. The biopeptides detected are known to present antibacterial, anti-diabetic, anti-hypertensive, anti-thrombotic, antioxidant, and immunomodulatory activities, while ACE enzyme and dipeptidyl-4 (DPP-IV) inhibitors were also identified. Based on these results, Tsalafouti cheese presents an interesting bioactive peptides profile that may act as special motivation for consumers to choose this specific cheese. Full article

Diet-related diseases and mortalities are assuming epidemic proportions globally. It is more worrisome in the Global South, especially in Africa, where the healthcare system is not resilient to the public health burden. There is a growing effort around the world to foster urban food system policies that would checkmate the failing health of the public and ensure improved quality of life. However, these efforts seem non-existent in many African regions. Therefore, there is a need for heightened efforts in these areas to address the food system and ensure a global healthy society. This study identified Nnewi, Nigeria, in sub-Saharan Africa, a typical urban area in Nigeria, and analyzed the public health challenges attributed to the non-existent food system policy and poor nutritional practices. The Milan Urban Food Policy Pact model, which has been successfully implemented in many cities, was adopted to propose a sustainable food system policy for Nnewi. Key policies proposed include autonomous local government power, government-assisted programs, clean and sustainable amenities, agricultural reforms, nutrition education, and reductions in food wastage to achieve a circular economy. An evaluation tool for implementing the food system policy was also developed. Overall, implementing the food system policies proposed herein would improve the quality of life of Nnewi residents. Other urban areas could also adopt similar food system policies to achieve the Sustainable Development Goals of a healthy and resilient global society. Full article

Oxidative stress is thought to be one of the common mechanisms for several neonatal diseases in premature infants. Moreover, fat-soluble antioxidant vitamins, i.e., retinol and α-tocopherol, have been found to be low in preterm neonates; however, data are limited. The aim of this was to assess the circulating α-tocopherol and retinol concentrations in preterm infants at birth and investigate if they are related to gestational age. Retinol and α-tocopherol were measured on the first day after birth in 30 preterm neonates with HPLC. Means ± SD of serum retinol and α-tocopherol were 392.0 ± 162.9 μg/L and 6.83 ± 3.02 mg/L, respectively. In total, 73% of infants had a very low birth weight (<1500 g) and 23.3% were small for gestational age (SGA). Moreover, 10% of neonates had a retinol deficiency and 20% had an α-tocopherol deficiency. The retinol concentration was lower in SGA infants compared to appropriate for gestational age ones (340.85 ± 75.89 vs. 407.60 ± 179.83 μg/L, correspondingly p = 0.030). Retinol was linearly related to gestational age (Pearson’s rho = 0.84, p < 0.001) but the association did not remain significant after an adjustment for birth weight (partial rho = 0.193, p = 0.316). α-tocopherol was nonlinearly associated with gestational age (Spearman’s rho = 0.470, p = 0.044). The assessment of the vitamin status and potential deficiency in neonates is crucial in order to appropriately support the nutritional needs of newborns. Full article

Gluten-free products present huge advantages for individuals with gluten intolerance or celiac disease. The most influential strategy to develop a product comparable to wheat-containing gluten products is to promote its nutritional and sensorial attributes. Recently, rice flour and teosinte flour were used to develop gluten-free bread. As a result, this work aimed to compare the physical/technological attributes of bread made with rice flour and teosinte flour with corn fiber fortification and examine consumer acceptance and purchase intent. An extreme vertices mixture design decided that a teosinte flour (43.4%), high protein white rice flour (55%), and high protein brown rice flour (1.6%) ratio of gluten-free flour mixture for bread was best based on the sensory attributes utilized for the desirability function methodology. After optimizing the gluten-free flour mixture, the bread was fortified with corn fiber under 1.7 g and 3.8 g per serving, and it was evaluated to examine its physical/technological attributes, consumer perception, liking, emotions, and purchase intent. Incorporating fiber into gluten-free bread impacted the color and texture, giving lighter and yellower colors with a firmer texture. Likewise, concerning health benefit claims, gluten-free bread with fiber claims only improves the purchase intent and overall liking of bread containing 1.7 g per serving of fiber. The flavor attribute was the main driver for consumers’ purchase decisions. This product could be beneficial for consumers who are seeking fiber in their diet. Full article

Healthy dietary patterns can play a major role in preventing chronic diseases. Improving nutrition-related knowledge in young individuals is considered a promising approach to adopting healthy dietary behaviors, thus improving outcomes later in life. However, healthy eating habits in college students may prove challenging to acquire and maintain. This cross-sectional pilot study aimed to investigate the relationship between nutrition knowledge and its effect on dietary factors, body weight, and body composition in female college students in Turkey. Second- and third-year female college nutrition students (NS), (n = 85) and corresponding non-nutrition/non-health sciences students (NNS) (n = 80), aged 20–22 years old, were evaluated using a validated nutrition knowledge questionnaire, 24 h recalls, anthropometry, and body composition analysis using bioelectrical impedance during the 2015–2016 academic year. The findings revealed that nutrition knowledge was positively associated with increased intake of water, fruits and vegetables, grains, and fiber, whereas total carbohydrate intake exhibited an inverse relationship with nutrition knowledge. Moreover, protein and lipid intake, while not significant, appeared to show higher and lower values, respectively, for the NS participants compared to NNS, revealing a healthier trend for more nutrition-knowledgeable students, which was similar to the finding of a marginally better body composition profile in nutrition-knowledgeable students. As young adulthood is critical for the development of dietary habits, demonstrating the effectiveness of nutrition education is important as a potential tool for public health in terms of improving the risk of chronic diseases.

Systematic and random errors based on self-reported diet may bias estimates of dietary intake. The objective of this pilot study was to describe errors in self-reported dietary intake by comparing 24 h dietary recalls to provided menu items in a controlled feeding study. This feeding study was a parallel randomized block design consisting of a standard diet (STD; 15% protein, 50% carbohydrate, 35% fat) followed by either a high-fat (HF; 15% protein, 25% carbohydrate, 60% fat) or a high-carbohydrate (HC; 15% protein, 75% carbohydrate, 10% fat) diet. During the intervention, participants reported dietary intake in 24 h recalls. Participants included 12 males (seven HC, five HF) and 12 females (six HC, six HF). The Nutrition Data System for Research was utilized to quantify energy, macronutrients, and serving size of food groups. Statistical analyses assessed differences in 24 h dietary recalls vs. provided menu items, considering intervention type (STD vs. HF vs. HC) (Student’s t-test). Caloric intake was consistent between self-reported intake and provided meals. Participants in the HF diet underreported energy-adjusted dietary fat and participants in the HC diet underreported energy-adjusted dietary carbohydrates. Energy-adjusted protein intake was overreported in each dietary intervention, specifically overreporting beef and poultry. Classifying misreported dietary components can lead to strategies to mitigate self-report errors for accurate dietary assessment. Full article
