The Mediterranean Diet (MD) is considered by the Food and Agriculture Organization of the United Nations (FAO) as “the best for people and the most sustainable for the environment”. In the era of Big Data, new tools are emerging to facilitate health care research. One form of Big Data is the one that accumulates in the traffic caused by publications on the web and social networks. These data can provide valuable information about the epidemiological patterns of certain behavior and interest of the population. The objective of this study was to explore through websites and its associated official social media on information related to different publications of both international or national nutrition official agencies as well as publications of scientific diffusion for the design of future nutritional education and MD programs. This study opens up future avenues of research, such as studying the acceptance of post writing in other languages in those northern European countries where MD is being implemented. Or through the use of subtitled videos, due to the great acceptance of this format. The MD remains in 2020 considered the best option to follow a healthy diet without difficulties, therefore it is very important to continue promoting the need for good nutritional health based on its qualities.

There are difficulties planning female training. The aim of this meta-analysis work is to know results obtained in studies on the relationship between the menstrual cycle (MC), diet, metabolism and performance in sportswomen. This work began in January-2022 looking differences in performance depending on the MC phase; exclusion criteria after 2015, non-experimental articles with quality indexes >Q2. We finally worked on 11 articles. Perception of the majority of sportswomen is that MC does have an impact on sports performance, as they are affected both physically and psychologically depending on the MC phase. Participant characteristics, such as training history, may also contribute to the variety of responses observed in studies. MC phase where performance may be reduced is in the Early Follicular Phase and may improve in the other MC phases. The effects found maybe of most relevance to female athletes.

The quality of diet can be measured using diet quality indices, based on knowledge of associations between diet and health. The objective of this work was to evaluate whether the International Diet Quality Index is suitable for use as a diet quality index in populations of Mexican university girls. A cross-sectional nutritional survey was conducted at the University of Chihuahua (Mexico), collecting semi-quantitative nutritional information and socio-economic and lifestyle data from a representative sample of 400 women. Mean (Standard Deviation (SD)) age was 21.43 years (SD: 3.72); 59.1% were normal weight, 26.6% overweight, 15.3% obesity. The Diet Quality Index-International (DQI-I) was developed according to the method of Kim et al. (2003) and focused on major aspects of a high-quality diet (variety, adequacy, moderation and overall balance). The total score of Diet Quality Index-International reached 53.86% (SD: 11.43), indicating that the general diet of Mexican women a poor-quality diet. Adequacy scored highest, followed by moderation and variety. Overall balance scored the lowest. Variety: 26.3 % consumed less than 4 food groups daily, only 12.8% take more than 1 serving from each food group, and 50.6% consumed only one source of protein daily. Regarding adequacy, a large proportion of the population reported an intake of proteins, vitamin C, calcium, iron, and fruit greater than 50% of recommendation; the vegetables, fiber and grain groups were less 50%. Poor scores were obtained for total fat and SFA consumption (moderation). No statistically significant differences are observed for any of the variables under study and score of the Diet Quality Index-International: body mass index, weight, physical activity level, education level of father and mother, location of lunch, breakfast considered important, knowledge of nutrition, which allows us to consider a relatively uniform population in its eating habits. These people are close to a Westernized diet, and an intervention in nutritional education would be advisable to improve the intake of unprocessed foods, consume a greater variety of protein sources and significantly reduce consumption of sugary foods and soft drinks. Due to different methodological and cultural factors, the proposed Diet Quality Index-International dietary assessment method does not seem to be useful in the assessment of diet quality in the Mexican university population, so further research is needed to develop a diet quality index adapted to the Mexican population.

IntroductionEndocrine disruptors such as bisphenol A (BPA), BPA glycidyl methacrylate, and other BPA acrylate–based derivatives have been related to type 2 diabetes, the metabolic syndrome, and obesity, among other metabolic disorders. The objective of this study is to examine the influence of BPA exposure by saliva analysis and daily physical activity on the risk of overweight/obesity in schoolchildren from southern Spain.MethodsThe study included 300 children (53.5% girls) aged 7–10 years. Participants completed a questionnaire with four sections: participant data, including demographic information and life and family habits; semi-quantitative food frequency questionnaire; anthropometric variables; and physical activity variables. All participants underwent dental examination, when the presence of sealants/composites in each tooth and other dental alterations was recorded, and samples of whole saliva were collected for UHPLC-MS/MS analyses.ResultsRisk of overweight/obesity was significantly influenced by body fat composition (OR = 10.77), not walking to and from school (OR = 1.38), lesser energy expenditure in sedentary activities (OR = 12.71), greater energy expenditure in sports (OR =1.62), and exposure to BPA from dental sealants/composites (OR = 1.38; p = 0.058).DiscussionFurther research is warranted on this issue in children, who may be especially vulnerable to the negative health effects of endocrine disruption.
