Methods: narrative review of human clinical studies, randomised controlled trials and meta-analyses evaluating kefir consumption in different population groups. Results relating to metabolic markers, inflammation, cognitive function, physical activity, gut health and safety were analysed. Results: kefir consumption is consistently associated with increased insulin sensitivity and a slight reduction in fasting glucose levels. The effects on lipid profile, blood pressure and systemic inflammation are mixed. A modulation of the gut microbiota is observed, with an increase in beneficial bacteria and improved intestinal permeability. The evidence regarding brain health is preliminary, with some indications of cognitive improvement and enhanced well-being. Potential benefits in physical performance and recovery have also been reported. Kefir has a favourable safety profile, with mild and transient adverse effects.

When present in appropriate quantities, they help to maintain neuroendocrine and immune homeostasis in situations of high physiological demand. Adaptogens can normalize biological functions and strengthen systems affected by stress, protecting the organism against psychological and environmental insults. Objectives: to evaluate the bidirectional relationship between micronutrients and stress, with emphasis on the role of adaptogens. Methods: we reviewed the literature and selected relevant studies, mainly randomized controlled trials and systematic reviews and meta-analyses. Results: there is a bidirectional association between stress and micronutrient status: stress affects nutritional status via multiple mechanisms, including increased demand, reduced intake and absorption, and changes in eating habits. This could lead to micronutrient deficiency, which, in turn, compromises the body's response to stress. Conclusions: stress can exhaust our supply of specific micronutrients, and even slight deficiencies can affect energy metabolism, leading to tiredness, mental and physical fatigue, and a reduced ability to adapt to stress. Adaptogens can strengthen resistance to stress and prevent stress from becoming chronic.

CrossFit® athletes often have a high body mass index (BMI), particularly men, due to greater muscle mass, whilst their body fat percentage is usually within a healthy range. However, a significant proportion of these individuals do not meet their energy requirements, particularly women, increasing the risk of relative energy deficiency in sport (REDs), which affects recovery, hormonal function, bone health, and immunity. A high protein intake is observed at the expense of carbohydrate intake, which is essential as fuel for intense training. Furthermore, there is a frequent insufficient intake of key micronutrients such as vitamin D and zinc, which can affect protein synthesis, immune function, and muscle performance.

Furthermore, bioactive peptides are generated during digestion, which, together with calcium, contribute to the regulation of body weight and the control of high blood pressure. The lactose is not only a source of energy but also enhances calcium absorption and acts as a prebiotic and a precursor to essential molecules. Despite the controversy surrounding milk fat, recent scientific evidence recommends the consumption of whole dairy products containing bioactive compounds, such as short-chain fatty acids and medium-chain triglycerides, which have been shown not to increase cardiovascular risk in healthy individuals. Furthermore, the phospholipids and sphingolipids in the membrane of milk fat globules promote neurodevelopment in newborns and prevent cognitive decline during ageing. Due to the heterogeneity of dairy products in terms of their composition and physical structure, to assess their impact on health it is essential to analyse the role of the matrix as a determining factor in the effects of their nutrients, considering not only the bioactivity and functionality of all their components, but also the interactions between them.</p>","PeriodicalId":19385,"journal":{"name":"Nutricion hospitalaria","volume":" ","pages":"7-10"},"PeriodicalIF":1.3,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148352123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
