In order to encourage discussions on "polyunsaturated fatty acids" and health, the Brazilian branch of the International Life Sciences Institute (ILSI) promoted the XII International Workshop Series on Foods with Functional Properties and/or Health Claims (28-29 November 2013) which consolidated knowledge, presented scientific advances, and promoted exchange of experiences on "Polyunsaturated Fatty Acids: Health Impacts". Various topics were addressed at this meeting including: nutritional needs and consumption issues; impact on chronic diseases: cardiovascular diseases and cancer; influence on gene expression; immunological system and inflammation; sources of these fatty acids; benefits during pregnancy and childhood; cost and benefit of supplementation; and regulations (legislation). In general terms, the event presented evidence of the benefit of polyunsaturated fatty acids on cardiovascular diseases, pregnancy, breastfeeding, and infant development, as well as possible influence on gene expression, contributing to their relationship with the immunological system and, therefore, inflammatory processes. The Grey Literature
Soils are the largest terrestrial C pool on Earth. However, most studies only investigated soil organic carbon (SOC) storage on surface soils layers. This has resulted in lack of knowledge on SOC dynamics in deep soil layers despite the fact that they contain a significant portion of the stored organic C. This study assessed how contrasting land uses and agronomic practices affect SOC stocks up to a 5‐m depth, and investigated superficial SOC concentration, and particle and density fractionation in a case study in the U.S. Southeastern Plains. On average, deep (90–500 cm) SOC accounted for 80% of total organic C across the investigated land‐use systems. A close relation between SOC concentration and Mehlich‐3 extractable Al and Fe concentration in deep soil samples suggested that non‐crystalline metals play a key role stabilizing deep SOC in this system. Land use had a significant effect only on superficial SOC concentration, and light, heavy, and mineral associated organic C within micro and macroaggregates. Soils from native vegetation, and non‐irrigated sod‐based rotation plots showed greater concentrations of SOC in almost all assessed micro and macroaggregates fractions, whereas those from the conventional crop rotation and irrigated sod‐based rotation plots showed lower SOC concentration in all assessed fractions.
Nesta última década, o mercado de frutas e hortaliças aumentou significantemente, sendo que o mercado de alimentos minimamente processados (AMP) é o que mais cresce. Essa tendência pode ser justificada principalmente pela praticidade, que atualmente tem sido o foco principal do consumidor. Sendo assim, o objetivo desta revisão de literatura foi apresentar os alimentos minimamente processados como uma tendência de mercado. Conclui-se que a crescente demanda por esse mercado de produtos horti frutícolas frescos está relacionado também devido principalmente à inserção da mulher no mercado de trabalho, devido a um menor tempo na hora do preparo da refeição e uma maior tendência na obtenção de alimentos saudáveis frescos e de alta qualidade, pelos consumidores.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
