Background/Objectives: Athletes increasingly turn to nutrition and supplements enhance performance, yet the evidence surrounding efficacy of Mediterranean diet (MD) remains inconclusive. This scoping review aims evaluate identify gaps in existing literature provide implications for future research on MD’s potential improve athletic performance across various demographics, sport types, measures. Methods: We conducted a systematic search peer-reviewed studies published four databases (PubMed, Scopus, Scielo, Google Scholar) using following terms their combinations: “mediterranean diet”, “performance”, “athlete”, “sport”. The placed no restrictions experimental design or time period publication focused athletes regardless competitive level. examined targeted about effects key metrics, such as endurance, strength, speed, while also evaluating possible confounding factors like dietary intake, body composition, training status. further aimed by investigating consistency dosing protocols, supplementation duration, methodologies used. Results: preliminary findings suggest that some report benefits MD recovery only 40% show statistically significant improvements outcomes, often with methodological limitations. lacked homogeneity participant dosage, assessments, hindering comparability. Our highlights need incorporates standardized dosing, homogeneous athlete populations, controlled conditions. Conclusions: provides framework guide offers insights into role sports nutrition.

Olive cake was incorporated at a low inclusion rate (3.7%) into the rations of dairy cows through partial substitution maize, and its effects on milk production, general health, fertility traits were investigated. Multiparous purebred Holstein (n = 148) divided two groups: treated group 86) control 62). The ration (group C) modified by replacing 1 kg maize with an equal quantity olive T). experiment lasted from 60 days prepartum to 150 postpartum. Electronic aids utilized quantify daily yield detect estrus expression, while clinical uterine examinations performed weekly. Blood samples, epithelial cells, endometrial tissue samples collected subgroup healthy animals in both groups specific time points. examined determine β-hydroxybutyric acid (BHBA), acute phase proteins (haptoglobin [Hpt] serum amyloid A [SAA]), progesterone, pregnancy-associated glycoproteins concentrations. Uterine cells assessed for polymorphonuclear neutrophil (PMN) counts, expression nine genes encoding inflammatory cytokines immune system activation analyzed biopsy tissue. No significant differences (p > 0.05) observed between yield, morbidity, endometritis, or conception rates. However, T came approximately 6 earlier 0.013) than those C; progesterone concentrations day 7 subsequent cycle tended 0.07) be higher T. On 21, BHBA C < 0.05).

Published: March 11, 2025

Olive oil, the primary fat source in Mediterranean diet (MedDiet), is rich monounsaturated fatty acids (MUFA), especially oleic acid, which constitutes 70–80% of its composition. Extra-virgin olive oil (EVOO), produced by mechanically pressing olives, highest quality with an intense flavor and acidity <1%. In contrast, refined (ROO), a blend virgin oils, contains fewer antioxidants anti-inflammatory compounds. EVOO’s health benefits stem largely from MUFA content, linked to reduced risks cardiovascular disease (CVD), neurodegenerative conditions, certain cancers. Additionally, EVOO minor, but bioactive, components such as polyphenols, tocopherols, phytosterols, contributing oxidative stability, sensory qualities, health-promoting properties. These include like oleuropein, hydroxytyrosol, tyrosol, exhibit anti-inflammatory, cardioprotective, neuroprotective, anticancer effects. Epidemiological studies suggest inverse relationship between intake CVD, EVOO-enriched MedDiet interventions showing improved lipid profiles, blood pressure, lower event risk. The PREDIMED study highlights significant role reducing cardiometabolic This review explores impact chemical within framework on metabolic variables influencing health.
