A importância da alimentação saudável e estado nutricional adequado frente a pandemia de Covid-19 / The importance of healthy eating and adequate nutritional status in the face of the Covid-19 pandemic

A prevenção de doenças passa por um conjunto de cuidados diversos e no caso da COVID-19, o fortalecimento do sistema imunitário auxilia no combate a infeções, existem também diversos fatores que estão associados a riscos significativos para a infecção pelo COVID-19 e podemos destacar  a má alimentação e o  estado  nutricional  inadequado do  indivíduo  e  as  doenças  não  transmissíveis preexistentes  como  diabetes  mellitus,  doenças  pulmonares  crônicas,  doenças cardiovasculares e a obesidade. O estudo tem como objetivo destacar através de uma revisão literária a importância da alimentação saudável e o estado nutricional adequado para prevenção e manutenção da saúde frente a pandemia de COVID-19. Trata-se um estudo exploratório, por meio de uma pesquisa bibliográfica. De acordo com as literaturas estudadas alimentação adequada com a proporção correta de macro nutrientes e micronutrientes adequado contribui para o fortalecimento do sistema imunológico e a prevenção de doenças crônicas não transmissíveis

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
