Whey protein (WP) is a dairy food supplement and, due to its effects on fat-free mass (FFM) gain and fat mass (FM) loss, it has been widely consumed by resistance training practitioners. This review analyzed the impact of WP supplementation in its concentrated (WPC), hydrolyzed (WPH) and isolated (WPI) forms, comparing it exclusively to isocaloric placebos. Random effect meta-analyses were performed from the final and initial body composition values of 246 healthy athletes undergoing 64.5 ± 15.3 days of training in eight randomized clinical trials (RCT) collected systematically from five scientific databases. The weighted mean difference (WMD) was statistically significant for FM loss (WMD = −0.96, 95% CI = −1.37, −0.55, p < 0.001) and, in the analysis of subgroups, this effect was maintained for the WPC (WMD = −0.63, 95% CI = −1.19, −0.06, p = 0.030), with protein content between 51% and 80% (WMD = −1.53; 95% CI = −2.13, −0.93, p < 0.001), and only for regular physical activity practitioners (WMD = −0.95; 95% CI = −1.70, −0.19, p = 0.014). There was no significant effect on FFM in any of the scenarios investigated (p > 0.05). Due to several and important limitations, more detailed analyses are required regarding FFM gain.
Genotoxicity studies of plants with medicinal and nutritional properties are recommended by international regulatory agencies as part of the risk assessment. Due to their consumption as food, nutraceutical use and ethnopharmacological relevance, Campomanesia pubescens represents one of these plants to be studied. The aim of the present study was to evaluate the genotoxic, cytotoxic potential and clathogenic effects of the ethanolic extract obtained from the pulp of C. pubescens (EEFCP) fruits on rats submitted to experimental genotoxicity models and through the SMART test performed in Drosophila melanogaster. The comet assay and the micronucleus test were performed on peripheral and bone marrow blood, respectively, of Wistar rats orally treated with EEFCP at doses of 125, 250, 500 and 1000 mg per kg per bw for 28 days. In the SMART test, the standard cross between three mutant D. melanogaster strains was used. Larvae were treated with EEFCP at different concentrations and the wings of adult flies were evaluated for the presence/frequency of mutant spots and compared to the negative control group. Phytochemical analysis of EEFCP indicated high levels of flavonoids. The tests performed in rats showed that EEFCP did not present significant genotoxic or clastogenic effects. The biotransformation metabolites of EEFCP did not present genotoxic activity, as demonstrated by the SMART test. Together, all results indicate that, under the experimental conditions used, EEFCP did not reveal any preclinical genetic toxicity. Therefore, the safe consumption can be fomented increasing, consequently, the economic liquidity in the industrial market from the fruits of guavira.
This work had as thematic the study in analysis of foods from the perspective of the nutrition professional. The objective of the research was to seek the training of this professional for the then analysis of the performance in quality control and formulation of products, with the perspective of assistance to projects carried out on site. This research was conducted in a community cafeteria located in a university in the interior of the State of Mato Grosso do Sul - Brazil. As a data collection tool, preparation technical sheets were used in which costs were collected, the preparation order, and the nutritional value provided. Sensory observation was used as an analysis of the data in order to measure and analyze and interpret the reactions of food and material characteristics. It appears that with the identification, attributions and activities developed by a nutritionist in the area, it became possible to analyze the processing of raw material and industrialized food products, according to the needs presented by the site. As for the points not reached were not due to any other factors than those related to the specificities of the research site, which did not prevent the acquisition of theoretical, practical, scientific, social and environmental knowledge of the points concerning the area of action of the nutritionist professional within the field of food science.

The present experience report narrates a nutritional intervention in the area of individual and collective clinical nutrition that took place in a University Hospital (HU) in the interior of the State of Mato Grosso do Sul - Brazil. The main objective of this field work was the professional training for hospital and outpatient nutritional care through general and specific activities performed on site. The specific activities consisted in writing care protocols and standardization of hospital diets while the general activities consisted in the analysis of medical records, survey of clinical diagnoses, proposal of dietotherapic conduct, monitoring of nutritional status, prescription and dietary adequacy, preparation of nutritional guidelines and development, presentation and discussion of clinical cases. This work also reports on the difficulties in implementing and carrying out this intervention agenda and, given the results obtained, it was concluded that the field experience in the hospital area was a valid and beneficial opportunity in which it was possible to harmonize theory with practice.

In its latest report, the United Nations for Food and Agriculture Organization (FAO) pointed out that the number of those who go hungry increased for the third year in a row affecting about 821 million people worldwide in 2018. Moreover, for the most part, studies show that food insecurity tends to follow social trends in such a way that it is precisely population groups in minorities or marginalized who are most likely to be exposed to food shortages and/or lack of access to adequate food. In this scenario, the concepts of food safety and insecurity gain prominence in the international debate playing a role of relevance to global public health. Achieving a healthy and sustainable food model is today one of the main objectives of modern and globalized society. With this, the main objective of this study is to collect in the scientific literature and discuss briefly about the social, environmental and geopolitical determinants that are (or should be) involved in the continuous process of effective human right to adequate feeding.
