Melatonin is a hormone secreted in the pineal gland with several functions, especially regulation of circadian sleep cycle and the biological processes related to it. This review evaluates the bioavailability of melatonin and resulting metabolites, the presence of melatonin in wine and beer and factors that influence it, and finally the different benefits related to treatment with melatonin. When administered orally, melatonin is mainly absorbed in the rectum and the ileum; it has a half-life of about 0.45–1 h and is extensively inactivated in the liver by phase 2 enzymes. Melatonin (MEL) concentration varies from picograms to ng/mL in fermented beverages such as wine and beer, depending on the fermentation process. These low quantities, within a dietary intake, are enough to reach significant plasma concentrations of melatonin, and are thus able to exert beneficial effects. Melatonin has demonstrated antioxidant, anticarcinogenic, immunomodulatory and neuroprotective actions. These benefits are related to its free radical scavenging properties as well and the direct interaction with melatonin receptors, which are involved in complex intracellular signaling pathways, including inhibition of angiogenesis and cell proliferation, among others. In the present review, the current evidence on the effects of melatonin on different pathophysiological conditions is also discussed.

Background: In the last few years there has been emerging interest in substituting added sugars from juices with other sweeteners to make them healthier. But their long-term effects have been poorly evaluated. The aim of this study is to evaluate the effect of the addition of stevia, sucralose and sucrose (control) to maqui-citrus beverages on antioxidant and inflammatory status. Methods: a 3-arm parallel, randomized and triple blind clinical trial was performed in overweight subjects (n = 138), who consumed the test beverage (330 mL day-1) for 60 days. The following markers were determined: antioxidant status (ORAC, homocysteine, and oxidized LDL), safety parameters (ALP, AST, ALT, and total bilirubin), lipid profile (total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglycerides) and inflammatory biomarkers (IL-6, TNF-a, and IL-10). Results: The homocysteine levels significantly increased after consumption of sucralose (27%, p = 0.001) and sucrose (40%, p = 0.006). A significant increase in the IL-10 concentration after consumption of the stevia sweetened beverage, and in ORAC values (21%) in subjects with lower basal antioxidant status were observed. The HDL and total cholesterol levels significantly increased after consumption of sucralose (p = 0.039) and sucrose (p = 0.001), respectively. No changes in triglycerides, LDL or oxidized LDL were observed. Conclusions: Oxidative stress and an inflammatory response were observed after consumption of these sweetened beverages, with the exception of stevia, which produced an anti-inflammatory response. The possible antioxidative effects of this polyphenol-rich beverage may only benefit those individuals with poorer antioxidant status. Many randomized controlled trials at normal levels of consumption using commonly consumed sweeteners are necessary to clarify their roles in health.

La vejez, ancianidad, o edad avanzada constituye un grupo extraordinariamente heterogéneo, de tal modo que la fecha de comienzo de esta etapa fisiológica no está claramente delimitada. Algunos autores la definen a partir de la edad de jubilación. La OMS indica como cifra los 65 años, aunque debido al aumento de la esperanza de vida cada vez se considera población de edad avanzada a personas más mayores (en torno a los 75 años en adelante) tendiendo a conceder menor importancia a la edad cronológica respecto a la situación funcional.

Stevia, sucralose and sucrose added to a maqui-citrus beverage and their effects on glycemic response in overweight subjects: a randomized clinical trial
(Elseiver, 2021-02-26) Villaño Valencia, Débora; Masoodi, Hedyeh; Marhuenda, Javier; García-Viguera, Cristina; Zafrilla, Pilar; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura
Background: Low-caloric sweeteners represent a good alternative to the extra boost of energy of sugar-sweetened beverages. However, their long-term effects have barely been assessed. In the present study, the influence of low-caloric sweeteners added to a maqui/Citrus beverage on the glycemic profile has been evaluated. Methods: A parallel, randomized and triple blind clinical study was performed in overweight subjects (n = 138), who consumed 330 mL/day of a beverage added with Stevia, Sucralose or Sucrose, for 60 days. Results: BMI did not change significantly with any treatment. Fasting glucose increased after the short-term consumption of Sucrose added beverage (26%), as well as with the addition of the low-caloric sweeteners, but in a lesser extent: 11% for Stevia and 20% for Sucralose. Insulin concentrations did not change significantly with any drink, which resulted in a significant increase in HOMA-IR with Sucralose (p = 0.002) and Sucrose (p = 0.001). Conclusions: The results obtained link the consumption of sucrose sweetened beverages with a disbalance in glycaemic response, and a better response with Stevia addition, although it also produces certain negative effects on glycemic control. The evidence available to date is not conclusive enough to advise the wide use of LCS. ClinicalTrials.gov NCT 04016337.

Ginger, Zingiber officinale, is a member of the Zingiberaceae family, used in traditional medicine for treatment of a variety of conditions. Many pharmacological activities have been reported for this plant (anti-inflammatory, anti-tumorigenic, anti-apoptotic, anti-hyperglycemic, cancer-chemopreventive, and anti-lipidemic). Cardiovascular disease, which includes coronary artery disease, acute myocardial infarction, peripheral arterial disease, and stroke, is one of the leading causes of death worldwide. In recent years, several studies have described that ginger can control or improve some cardiovascular risk factors such as cholesterol levels, hypertension, or atherosclerosis. The aim of the present review is to summarize the effects of ginger bioactive compounds on cardiovascular diseases.

Es necesario establecer unos conceptos para definir una de las etapas vitales de la mujer como son: la menopausia es una fecha, el momento en que cesan de modo permanente las funciones del ovario y, por ello, los ciclos fisiológicos de la menstruación; la perimenopausia es el período caracterizado por el conjunto de fenómenos que se manifiestan por una serie de cambios biológicos, endocrinológicos y clínicos; y la transición menopáusica es el período que precede al período menstrual final y que se caracteriza por un aumento de la variabilidad menstrual. Actualmente existe un consenso sobre el establecimiento de tres fases principales en el patrón reproductivo feme-nino, según los criterios STRAW10+ (Stages of Reproductive Aging Workshop): etapa reproductiva, transición a la menopausia, y postmenopausia (Harlow y cols., 2012). A su vez estas fases están divididas en función del momento de menopausia1, que es una fecha concreta (cese de periodo menstrual durante 12 meses consecutivos) y tiene lugar en torno a los 50 años. En este sentido, puede decirse que hay un paralelismo entre la menopausia y la pubertad. En la pubertad, existe un momento, la menarquia y luego hay un período, el período puberal que se extiende antes, durante y después de la menarquia.

Alcohol consumption by italian and spanish university students in relation to adherence to the mediterranean diet and to the food neophobia: a pilot study
(MDPI, 2022) Aiello, Paola; Peluso, Ilaria; Villaño Valencia, Débora; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura
This work aimed to relate alcohol consumption with adherence to the Mediterranean diet (MD) and with food neophobia (FN) among Italian and Spanish university students. Volunteers (n = 194, 108 Italian and 86 Spanish), recruited at the La Sapienza University of Rome and the Catholic University of Murcia, filled in standardized questionnaires to evaluate alcohol consumption (AUDIT), FN (FN Scale: FNS), and adherence to the MD (MDS-14, MED-55, QueMD). In addition to the previously reported QueMD sub-score (aMED), a sub-score for non-typical MD foods (ntMED, carbonated and/or sugar-sweetened beverages (soft drinks), butter, margarine, or cooking cream, and manufactured sweets, pastries, and cakes) was evaluated. Italian females had higher MED-55 and FNS scores, and a lower AUDIT score than Spaniards (p < 0.01). Students who stayed with their family (resident) were more adherent to MD than those who moved away from home. Resident Italians consumed less beer, hard liquors, and cocktails than Spaniards on Saturday nights (p < 0.01). There were negative correlations between AUDIT and QueMD (R squared: 0.137, p < 0.05), and AUDIT and ntMED (R squared: 0.201, p < 0.01) in Spaniards, however, there was no relationship between AUDIT and other MD scores. In conclusion, this pilot study suggests that non-typical MD foods and Saturday night consumptions, related to being far from home, have a great impact on alcohol consumption.

Effects of a fruit and vegetable-based nutraceutical on biomarkers of inflammation and oxidative status in the plasma of a healthy population: a placebo-controlled, double-blind, and randomized clinical trial
(MDPI, 2021) Arcusa, Raúl; Carrillo, Juan Ángel; Xandri-Martínez, Raquel; Cerdá, Begoña; Villaño Valencia, Débora; Marhuenda, Javier; Zafrilla, Pilar; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
There is scientific evidence of the positive effect of polyphenols from plant foods on inflammation and oxidative status. The aim of the present study was to investigate whether treatment with a high-polyphenolic nutraceutical reduces the plasmatic concentration of certain oxidative and inflammatory biomarkers in a healthy population. One hundred and eight subjects were selected and stratified by sex in the intervention group (n = 53) and the placebo group (n = 55). Ninety-two subjects completed the study after two 16-week treatment periods separated by a four-week washout period. The results revealed statistically significant differences in subjects treated with the polyphenolic extract compared to the placebo: A decrease in homocysteine, oxidized low-density lipoprotein (OxLDL), TNF-α, sTNFR1, and C-reactive protein (CRP). The most significant decrease was observed for OxLDL (from 78.98 ± 24.48 to 69.52 ± 15.64; p < 0.05) and CRP (from 1.50 ± 0.33 to 1.39 ± 0.37; p < 0.05), both showing significant differences compared to the placebo (p < 0.001). Moreover, catecholamines increased after the administration of the product under investigation, especially in the case of dopamine (from 15.43 ± 2.66 to 19.61 ± 5.73; p < 0.05). Therefore, the consumption of a nutraceutical based on fruit and vegetables with a high polyphenol content seems to improve the parameters related to health benefits (oxidative and inflammatory biomarkers), including remarkable changes in the expression of catecholamines.

Plant-based and hybrid patties with healthy fats and broccoli extract fortification: more balanced, environmentally friendly alternative to meat prototypes?
(MDPI, 2025-02-01) González Peñalver, José Miguel; Martínez Aldaya, Maite; Villaño Valencia, Débora; Virseda Chamorro, Paloma; Beriain Apesteguía, María José; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura; Ciencias; Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD; Gobierno de Navarra / Nafarroako Gobernua
Hybrid and plant-based products are an emerging trend in food science. This study aimed to develop three patty prototypes (meat, hybrid, and plant-based) enhanced with vegetable fat replacement and broccoli extract using a soy allergen-free protein matrix treated with high hydrostatic pressure (HHP) and sous vide cooking to create sustainable and nutritious burger alternatives. The samples were evaluated for microbiological safety, proximal composition, physicochemical properties, sensory characteristics, and carbon footprint. The key findings revealed that the plant-based patties had the smallest carbon footprint (0.12 kg CO2e), followed by the hybrid patties (0.87 kg CO2e) and the meat patties (1.62 kg CO2e). The hybrid patties showed increased hardness, cohesiveness, gumminess, and chewiness compared to the meat patties after sous vide treatment. This improvement likely results from synergies between the meat and plant proteins. Regarding the treatments, in all the samples, the highest hardness was observed after the combined HHP and sous vide treatment, an interesting consideration for future prototypes. Sensory analysis indicated that the plant-based and hybrid samples maintained appealing visual and odour characteristics through the treatments, while the meat patties lost the evaluator¿s acceptance. Although further improvements in sensory attributes are needed, hybrid patties offer a promising balance of improved texture and intermediate carbon footprint, making them a viable alternative as sustainable, nutritious patties.

Most university students do not follow recommendations for fruit and vegetable intake, with a consequent increase in the prevalence of cardiovascular disease (CVD) risk factors. The aim of this study was to compare obesity prevalence and biomarkers of metabolic status between Italian and Spanish university students, in relation with the consumption of fruits and vegetables. Food consumption, adherence to a Mediterranean diet (MD), level of physical activity (PA), blood glucose, total cholesterol, triglycerides and ketones, blood pressure, and body composition were evaluated. Among CVD risk factors, only glucose was significantly higher in Spaniards (SP), and only 3.1% of SP presented ketosis. SP had a higher percentage of energy from fat. Although adherence to MD and fruit and vegetable consumption did not differ between Italians and SP, students who consumed at least four servings of fruit and vegetables (FV group) showed better values for pressure and metabolic parameters than the no FV group. We observed an association between consumption of fruit and PA. Students who consumed more vegetables than fruit reported a better body composition profile and lower glucose concentrations. As previously suggested, in addition to PA, two servings of fruit and three servings of vegetables per day should be recommended.
