Background: The relationship between sports participation and food preferences in adults, as well as the influence of gender, is still unclear. Objective: The objective of this study was to investigate the association between sports participation and individual food preferences and to explore potential gender differences among sports participants in a large group of Italian adults. Methods: This cross-sectional study involved 2665 adults (aged ≥ 18 years) who lead normal lives and underwent a routine lifestyle and dietary assessment at a clinical centre specialising in nutrition, metabolic health, and lifestyle counselling in Rome. Participants completed an online questionnaire on food preferences (19 foods) and sports practice. Multivariate logistic regression models, adjusted for age, sex, and smoking, were used to assess associations. Results: Sports participation was defined as engaging in structured physical activity at least once per week and was reported by 53.5% of subjects (men: 60.1%; women: 49.0%; p < 0.0001). After adjustment, active individuals were significantly more likely to prefer plant-based drinks, low-fat yoghurt, fish, cooked and raw vegetables, fruit, whole grains, tofu, and dark chocolate (all p < 0.05) and less likely to prefer cow’s milk (p = 0.018). Among sport participants, males were more likely to prefer meat (general, white, red, processed) and eggs, while females preferred plant-based drinks. No significant gender differences were observed for dairy products, legumes, or fish. Differences in food preferences were also observed according to the type of sport, with bodybuilders showing higher preference for tofu and dark chocolate. The strongest associations were found in the 25–44 age group. Conclusions: Sports participation is independently associated with specific food preferences, characterised by greater preference for plant-based and fibre-rich foods, and gender differences in food choices persist even among active adults. These findings highlight the need to consider both sports participation and gender when designing nutritional interventions. Full article

Background: The differential effects of post-exercise rehydration beverages on inflammatory processes and organ protection remain incompletely characterized. This study investigated how beverages with distinct compositions influence urinary biomarkers following endurance exercise. Methods: In a randomized crossover design, eight trained male runners performed 6000 m pace running followed by consumption of 500 mL of either: water (Drink 1), hypotonic sports drink (Drink 2, 200 mOsm/L), oral rehydration solution (Drink 3, 270 mOsm/L), or modified hypotonic formulation (Drink 4, 200 mOsm/L). After 60 min, participants completed a 1000 m time trial. Urine samples were collected at baseline, post-6000 m, and post-1000 m for analysis of biochemical parameters and inflammatory cytokines. Results: No significant differences in 1000 m performance were observed between trials. Drink 3 significantly reduced creatinine and uric acid excretion compared to other beverages (p < 0.05), suggesting decreased waste product elimination. Creatinine-corrected intestinal fatty acid-binding protein values were lower with Drinks 2 and 3, indicating potential intestinal protection. Notably, Drink 4 showed modest but significant enhancement of IL-4 excretion (p < 0.05, ηp² = 0.347), demonstrating beverage-specific modulation of anti-inflammatory cytokines with moderate effect sizes. Conclusions: Different beverage formulations exert distinct effects on waste product elimination, intestinal organ damage markers, and inflammatory cytokine profiles. These findings suggest that beverage selection should be tailored to specific recovery priorities and training contexts. Full article

Objective: Eating habits established during adolescence play a crucial role in shaping both current and future health status. However, adolescents today appear to be increasingly adopting poorer dietary and lifestyle habits. This study aims to investigate eating behaviors and supplement use among adolescent students who participated in the EduALI nutrition education project. Methods: The project included first-year students from six sports-oriented scientific high schools in Florence. The students participated in six nutrition sessions, completing the International Physical Activity Questionnaire to assess physical activity performance, a questionnaire on dietary supplement use, and, to assess eating habits a Food Frequency Questionnaire (FFQ), as well as the Medi-Lite questionnaire to specifically assess adherence to the Mediterranean diet (MD). The data from the FFQ were compared with national dietary guidelines. Results: The study sample consisted of 83 students (69.9% male; average age: 13.8 ± 0.4 y). The results showed that 61.4% of participants had used supplements in the past year, most commonly mineral salts (56.6%) and vitamins (54.2%), followed by botanical products (22%), sports drinks (16%), proteins/amino acids (8%), and creatine (2%). Alarmingly, 27.7% used supplements without medical supervision. Students involved in individual sports had higher supplement consumption than those in team sports, especially creatine use. Eating habits revealed poor adherence to both the MD and Italian dietary guidelines, with deficiencies in fruits, vegetables, olive oil, fish, and legumes, and excessive intake of cheese, meat, especially red and processed meats. Conclusions: A high prevalence of supplement use among adolescents was observed, along with poor adherence to dietary guidelines and MD. These findings underscore the need for targeted, school- and sport-based interventions to enhance adolescents’ nutritional awareness and responsible supplement use. Full article

Algae-based supplements are gaining attention for their potential metabolic, antioxidant, and anti-inflammatory properties in sports nutrition. Methods: A 30-day pilot randomized controlled trial was conducted in 70 healthy male athletes (mean age 25.4 ± 4.9 years) from competitive soccer and handball teams. Participants were randomly assigned to a supplementation group (6 g/day of Ulva-derived algae powder) or a control group. Both groups followed identical training routines and adhered to standardized nutritional recommendations, including macronutrient distribution and permitted supplements (e.g., isotonic drinks, protein shakes). Biochemical markers analyzed at baseline and post-intervention included HbA1c, lipid profile, malondialdehyde (MDA), catalase, myeloperoxidase (MPO), erythrocyte sedimentation rate (ESR), and cortisol. Genetic polymorphisms related to metabolic traits were also assessed. Results: Significant group × time interactions (p < 0.001) were observed for HbA1c, LDL, triglycerides, MDA, MPO, ESR, and cortisol, all of which improved in the algae-supplemented group. Correlation analysis revealed associations between HbA1c and LDL/TG as well as between cortisol and MPO. No significant genetic modulation of responses was detected, although a trend was noted for cortisol variation and insulin resistance risk. Conclusions: Algae-based supplementation led to favorable metabolic, oxidative, and inflammatory changes. These findings suggest its potential utility as a nutritional strategy to support recovery in athletes during periods of high training load or competition. Full article

The impact of acidic beverages on dental restorative materials, such as composites and glass ionomers, is critical in conservative dentistry. Exposure to an acidic environment can lead to the degradation of these materials, affecting their durability and clinical effectiveness. We aimed to examine the effect of sports drink exposure on the surface roughness of composite and glass ionomer materials. This systematic review was conducted based on the records published from 1 January 2005 to 31 December 2024, according to PRISMA statement guidelines, using the databases PubMed, Scopus, Web of Science, and Embase. Following the inclusion and exclusion criteria, 10 studies were included in this review and 6 in the meta-analysis. Meta-analysis demonstrated a statistically significant increase in surface roughness (Ra parameter) for glass ionomer materials after immersion in sports drinks for one week and one month. No such significant differences were observed for composite materials. Despite the systematic review, the degree of material degradation presented by in vitro studies cannot be directly extrapolated to oral conditions due to factors such as the buffering capacity of saliva or irregular exposure times to sports drinks.

A unique isotonic sports drink (ISD) was created in this study using a pilot-scale short-wave ultraviolet light (UV-C, 892 mJ/cm², 20 °C) assisted by mild heat (UV-C/H, 534 mJ/cm², 50 °C), which was followed by the addition of yerba mate (Ilex paraguariensis) extract (YME). Consumer perception and microbiological and physicochemical stability during refrigerated storage (4 °C/23 d) were assessed for the ISD. Alicyclobacillus acidoterrestris (AA) spores and cocktails of yeasts and Escherichia coli were considerably inactivated by UV-C/H. The TEM and SEM micrographs showed that AA evidenced sustained severe structural damage. Furthermore, UV-C/H completely inactivated the native microbiota, while YME incorporation increased the initial aerobic mesophilic and mold-and-yeast populations by 0.48 and 0.70 log cycles, remaining stable during storage. YME addition enhanced total polyphenols, flavonoids and antioxidant activity by 2.7–3.7, 16.5–16.7 and 6.6–24.0 times compared to the untreated ISD and ISD-UVC/H samples. Except for sedimentation and turbidity, the other physical characteristics mostly did not change (going from 1494 ± 382 to 2151 ± 106 NTU). The initial 5-HMF value in the ISD was raised by UV-C/H treatment and YME addition. Notwithstanding, it stayed below the allowed threshold throughout storage. ISD-UVC/H+YME had a high overall acceptability score; 60% of panelists gave the drink a score of seven or higher. Additionally, the herbal taste of YME was well liked, and its bitterness was perceived as mild. These findings suggest that including YME and the UV-C/H treatment can produce an ISD of superior quality with distinct sensory attributes. Full article

Background/Objectives: Binge Eating Disorders are severe mental and physical health conditions, closely linked to lifestyle habits. The aims are to describe the prevalence of Binge Eating Disorders and their correlation with nutritional habits and lifestyle factors within the Spanish population. Methods: A descriptive, cross-sectional design was employed. Using non-probabilistic snowball sampling, an electronic survey was released. A total of 22,181 Spanish adults were evaluated, excluding those with any pathology or limitation at the time of survey response that could potentially affect their diet, such as hospitalization or confinement. The validated Nutritional and Social Healthy Habits (NutSo-HH) scale was used to collect data on nutrition, lifestyle, health habits, and socio-demographic variables. Descriptive and inferential statistics were used. Non-parametric tests were applied due to non-normal distribution. Results: Of the 22,181 sample subject (80.8% female), a total number of 260 individuals reported Binge Eating Disorder. The prevalence of Binge Eating Disorder was higher in women than in men (239 vs. 21 respectfully; 91.9%). Individuals with Binge Eating Disorder exhibited poorer nutritional indices (p < 0.001), higher consumption of ultra-processed and fast food (p < 0.001), sugary soft drinks (p = 0.01), and worse sleep quality (p < 0.001). Although time dedicated to physical activity was not different, individuals with Binge Eating Disorder were more sedentary and had lower health status (p = 0.11 for sport practice). Behavioral regulation plays a key role in managing BED, highlighting the need for personalized intervention strategies. Conclusions: Binge Eating Disorders are associated with lifestyle and health habits and worse quality of life. These data can help design public health programs for early detection and effective treatment. Full article

Background/Objectives: The high consumption rate of energy drinks among pupils is a serious public health concern in various countries, including South Africa. Excessive consumption of energy drinks that contain elevated caffeine and sugar levels has the potential to lead to the development of addictions, strokes, dehydration, sleeping disorders, mental health and central nervous disorders, hypertension, digestive problems, and anxiety. Most pupils regard energy drinks as regular soft drinks and lack knowledge of the active ingredients contained in energy drinks and their side effects. The objective of this study was to investigate factors influencing energy drink usage amongst pupils in the Mahikeng sub-district, Northwest Province. Methods: A quantitative cross-sectional survey was conducted amongst 505 pupils in the Mahikeng sub-district, Northwest, using self-administered questionnaires. Data were analysed using STATA software version 18 to examine associations between variables. Results: The energy drinks consumed most by pupils were Dragon (38.21%), Switch (28.97%), and Red Bull (14.62%). Factors and reasons influencing energy drink usage among pupils include all-night parties (3.1%), concentration (20.3%), being awake (43.1%), curiosity (2.2%), energy levels (23.1%), exams (13.8%), sports (8.7%), fatigue (6.9%), and health (2.3%). There was a strong association (p ≤ 0.05) between energy drink usage and sports activities amongst pupils. Conclusions: It is concluded that health education and promotion intervention programmes are required to educate pupils about the dangers of energy drink usage to prevent public health risks. Further studies, including research on primary school pupils, are necessary, considering that a substantial number of pupils were exposed to energy drinks at an early age. Full article

Background and Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a clinical pathological syndrome characterized by steatosis and fat accumulation in liver parenchymal cells in patients without a history of excessive alcohol drinking. Currently, there is no definitive treatment for MASLD, and its prevalence increases with age and obesity, and after menopause. Among the ways to treat it, we can mention regular sports exercises and the use of natural supplements. Therefore, the aim of this research is to investigate and compare the effects of aerobic-resistance training with royal jelly supplementation on changes in paraoxonase 1, oxidized LDL, liver function, and lipid profile in postmenopausal women with Dysfunction-Associated Steatotic Liver Disease. Materials and Methods: This semi-experimental study involved 23 women with Dysfunction-Associated Steatotic Liver Disease with an average weight (71.34 ± 11.63 kg), age (48.54 ± 3.88 years), and body mass index (27.63 ± 4.20 kg/m²). They were randomly divided into two groups: exercise + supplement (n = 12) and exercise + placebo (n = 11). Both groups performed eight-station resistance exercises (8–12 repetitions in 2–4 sets) for 8 weeks, with three sessions per week (for 35–40 min, from 10-15 RPE), and then, for 10–15 min of active rest, they performed aerobic exercises with an intensity of 40–85% of the target heart rate, in two-minute intervals with 45 s of active rest. Royal jelly supplement (500 mg on training days, before each training session) was consumed. Blood sampling was done before and 48 h after the last training session. Statistical analysis was performed using a variance test with repeated measures (two groups × two stages of pre-test-post-test) in SPSS software (Version 26) with a significance level of p < 0.05. Results: The results of the statistical analysis show that the effects of eight weeks of exercise + supplement and exercise + placebo on PON1, oxLDL, lipid profiles (HDL, LDL, TC, and TG), and liver enzymes (ALT, AST) in women with non-alcoholic fatty liver showed a significant difference (p < 0.05). The results show a significant increase in PON1 (p = 0.008) and HDL (p = 0.005) in the exercise + supplement group compared to the exercise + placebo group. But significant decreases in oxLDL (p = 0.031), TC (p = 0.045), TG (p = 0.013), LDL (p = 0.027), ALT (p = 0.015) and AST (p = 0.009) were observed in the exercise + supplement group compared to the exercise + placebo group (<0.05). The results show a significant increase in PON1 (p = 0.008) and HDL (p = 0.005) in the exercise + supplement group compared to the exercise + placebo group. However, significant decreases in oxLDL (p = 0.031), TC (p = 0.045), TG (p = 0.013), LDL (p = 0.027), ALT (p = 0.015), and AST (p = 0.009) was observed in the exercise + supplement group compared to the exercise + placebo group. Conclusions: Based on the results, it can be concluded that aerobic-resistance exercises with the addition of royal jelly can probably be an efficient and recommended strategy to minimize the harmful effects of Dysfunction-Associated Steatotic Liver Disease by affecting the activity of liver enzymes, paraoxonase 1, LDL oxidation, and lipid profile. Although exercise alone also yielded favorable results, according to the findings of this research, it can be said that exercise, combined with the use of royal jelly supplements, may have more positive effects on reducing liver complications and improving body function. However, in order to obtain more accurate scientific evidence, it is necessary to investigate more doses and timing of royal jelly in future studies. Full article

Background: Nutritional expectations have been shown to influence exercise performance via placebo and nocebo effects. The present study aimed to evaluate performance-enhancement expectations for coffee and energy drinks using the Stanford Expectations of Treatment Scale. Methods: A total of 402 participants (48.5% male) with an average exercise history of 4.53 years, engaging in average physical activity 3.91 times per week, were included in the study. Data collection was conducted through the Qualtrics platform. Results: Participants exhibited significantly higher positive expectations for coffee compared to energy drinks (p = 0.002), whereas negative expectations were more pronounced for energy drinks than for coffee (p < 0.001). Males and individuals engaging in anaerobic exercise expressed more positive expectations for energy drinks than females and those participating in aerobic or mixed exercise regimens. Additionally, high-frequency exercisers (≥4 sessions per week) reported greater positive expectations for both beverages and fewer negative expectations for coffee than low-frequency exercisers (≤3 sessions per week). Correlational analyses revealed weak but significant associations between expectations and variables such as exercise history, frequency, intensity, and age. Conclusions: The findings suggest that coffee is perceived as a more effective performance enhancer and exhibits greater placebo-inducing potential than energy drinks, which may elicit stronger nocebo effects. These group-specific perceptions should be considered by trainers, coaches, and researchers when addressing placebo–nocebo mechanisms in the context of sports and exercise. Full article

Objectives: This study aimed to evaluate and compare the consumption of dietary supplements (DS) in semi-professional male and professional female Spanish football players. Methods: The study involved 129 football players (92 men and 37 women) who completed a validated, self-administered questionnaire on the use of DS in athletes. Results: The results indicated that 96.12% of the sample reported taking DS, with the main reason for consumption being performance enhancement. The most commonly consumed DS were creatine monohydrate (66.77%), caffeine (56.59%), whey protein (48.06%), isotonic drinks (37.21%), vitamin D (27.91%), energy bars (27.13%), magnesium (20.93%), and vitamin C (20.16%). Additionally, significant differences were found between sexes regarding vitamin D consumption (p < 0.05; OR = 3.27 [0.36–2.00]). According to the Australian Institute of Sport DS classification, group A was the most consumed, followed by group B. Significant sex differences were found in the consumption of sports foods (p = 0.034; OR = 3.25 [0.05–2.31]) and medical supplements (p < 0.001; OR = 3.75 [0.52–2.12]). Sex differences were also found in place of purchase, source of recommendation, as well as the situation and timing of consumption (p < 0.05). Conclusions: The use of DS among Spanish football players was prevalent at 96.12%, with creatine monohydrate, caffeine, and whey protein being the most commonly consumed. Differences in consumption patterns were noted between sexes. Full article

Background/Objectives: Dental erosion occurs due to repeated contact between the teeth and acidic substances along with mechanical stress. Athletes are exposed to acids through the consumption of sports drinks, energy drinks, and isotonic solutions; they also undergo mechanical stress during training and competition, making them prone to a higher prevalence of dental erosion. Therefore, our aim was to determine the erosive potential of beverages consumed by athletes. Methods: We conducted a systematic review of 1466 articles found on nine search engines between 1997 and 2021. We included observational studies and clinical trials in English, Portuguese, and Spanish on beverage consumption in athletes of both genders. Results: A total of four studies involving 567 athletes from four countries were identified. The prevalence of dental erosion ranged from 19.4% to 100%, and the severity assessments showed that between 52.4% and 75.2% of athletes had enamel affected, and 24% to 57.1% had both enamel and dentin affected. Only one study found that the consumption of sports drinks by swimmers practicing in chlorinated pools doubles the risk of developing dental erosion. Bias was low in half of the studies. Conclusions: The available evidence suggests that the consumption of sports drinks alone is not associated with dental erosion. However, to establish more conclusive evidence on the erosive potential of sports drinks, energy drinks, and isotonic solutions on the oral health of athletes, more prospective cohort studies are needed. These studies should include a standardization of indices and variables to which athletes are subjected, including dietary and healthcare habits, oral conditions, and protective factors. Furthermore, a larger number of athletes must be included to establish more conclusive evidence on the erosive potential of sports drinks, energy drinks, and isotonic solutions on athletes’ oral health.

Vitamin D is a conditionally essential fat-soluble vitamin found in foods such as fish; fish oil; egg yolks; animal fats; some mushroom varieties; and fortified foods such as cheese, margarine, milk, infant formula, and some ready-to-eat cereals. Calcium (Ca) is found in milk, cheese, canned fish, ready-to-eat cereals, milk substitutes, dark green leafy vegetables, and sports drinks. There are more than fifty metabolites of vitamin D. Vitamin D participates in immune regulation, apoptosis induction, insulin secretion, inflammation, cell differentiation, calcium balance and regulation, bone mineralization, and phosphorus homeostasis. Ca is an essential macro-mineral involved in bone and teeth matrices, strength, and hardness; muscle and cardiovascular movement; neurological messaging; and in the release of hormones. Peer-reviewed journal articles were accessed from the search engine PubMed. The authors reviewed the references in the peer-reviewed journal articles, websites, and review articles if the authors proposed a new theory or mechanism. Vitamin D and Ca have important relationships; therefore, many factors may impede or interfere with the body’s ability to absorb or utilize vitamin D and or Ca and may result in low or excessive levels of each. Additionally, genetic/medically related absorption issues and low intake may also result in deficiencies. This review discusses the introduction of each, their functions, absorption, somatic transportation, the relationship between vitamin D and Ca, and recommendations and supplementation strategies if available.

(1) Background: This study aimed to investigate the effects of fluid restriction and intake (water vs. sports drink) on shooting accuracy and speed in adolescent handball players, a population with high sensitivity to hydration levels yet understudied in this context. (2) Methods: A total of 47 adolescent competitive handball players (15.04 ± 1.5 years) were included in this study, and the participants were divided into low, average, and high performance according to their shooting performance in the familiarization session. All participants were exposed to fluid restriction and intake conditions during handball training on different days. Before and after the training sessions, changes in shooting accuracy and speed were evaluated. (3) Results: The training protocol resulted in body mass loss in the Average Performer group (p = 0.001). Compared to fluid restriction, fluid intake (water intake and sports drink intake) post-training had a positive main effect on shooting accuracy, F(2, 88) = 34.32, p < 0.001, η_p² = 0.44, and shooting speed, F(1, 61) = 4.05, p = 0.35, η_p² = 0.84. (4) Conclusions: Hydration level plays an important role in shooting accuracy and speed performance in adolescent handball players. Therefore, fluid intake integrated into training or match sessions may contribute to the maintenance and improvement of shooting performance. Full article

Background: Participation in physical activity can improve the physical, mental, and social health of older adults, with greater benefits observed when they join sports clubs or groups rather than exercising alone. Despite the numerous advantages of older adults’ participation in sports clubs, research on this topic remains scarce. This study investigated the association between participation in sports clubs and weekly physical activity, perceived health status, and health behaviors (adequate rest and sleep and regular meals and nutritional supplementation) among Korean older adults. Methods: Data on 5146 individuals aged 60 years or older, collected from the 2022–2023 Korea National Lifestyle and Sports Survey, were analyzed using frequency, chi-square, and multivariate logistic regression analyses. Results: Significant differences were found in sex, age, weekly physical activity, perceived health status, adequate rest and sleep, regular meals and nutritional supplementation, use of exercise prescription and consultation services, participation in lifestyle physical education classes, and cessation of drinking and smoking based on participation in sports clubs. Sports club participation increased the frequency of weekly physical activity and improved perceptions of health status in older adults. The average odds ratios (ORs) for weekly physical activity were 6.667 (95% confidence interval CI = 4.316–10.297; p < 0.001), 5.237 (95% CI = 3.372–8.133; p < 0.001), and 3.042 (95% CI = 1.864–4.966; p < 0.001) for 1–2, 3–4, and 5 or more days of participation, respectively. The average ORs were 0.559 (95% CI = 0.264–1.183; p = 0.128) for inadequate rest and sleep, and 1.272 (95% CI = 0.555–1.694; p = 0.100) for adequate rest and sleep. Average ORs were 0.976 (95% CI = 0.497–1.915; p = 0.943) for irregular meals and nutritional supplementation, and 1.028 (95% CI 0.770–1.373; p = 0.851) for regular meals and nutritional supplementation. However, sports club participation was not significantly associated with sufficient rest and sleep or regular meals and nutritional supplementation. Conclusions: Older adults need support to join sports clubs, which can promote their physical activity and health. Full article
