Stable Isotope Values in Human Dentine Collagen and Fingernails Reveal Age‐Related and Socioeconomic Dietary Patterns in Brazil
Isotope fingerprinting for traceability in the amazon bioeconomy
First isotopic model mapping Amazon açaí provenance using δ18O and δD. • Model localizes 80–90% of true sites within the top 20% highest-probability area. • High exclusion strength: 95% of credible regions restrict origins to ∼2% of Amazonia. • δ18O and δD isotopes demonstrate feasibility for traceability in the bioeconomy. Açaí ( Euterpe spp. ) is a flagship product of the Amazon bioeconomy, recognized for its high nutritional value and economic…
Impacts of market economy access and livelihood conditions on agro-food transition in rural communities in three macro-regions of Brazil
Mapping carbon and nitrogen isotopic composition of fingernails to demonstrate a rural–urban nutrition transition in the Center‐West , Northeast, and Amazon regions of Brazil
The nutrition transition has not yet reached some remote villages in these regions of Brazil or that the nutrition transition has not yet reached all residents of these remote villages. On the other hand, in several villages there is a considerable adherence to the supermarket diet or that some residents of these villages are already favoring processed food
The influence of seasonal river flooding in food consumption of riverine dwellers in the central Amazon region
Factors influencing the food transition in riverine communities in the Brazilian Amazon
Nitrogen management challenges in major watersheds of South America
Urbanization and land use changes alter the nitrogen (N) cycle, with critical consequences for continental freshwater resources, coastal zones, and human health. Sewage and poor watershed management lead to impoverishment of inland water resources and degradation of coastal zones. Here we review the N contents of rivers of the three most important watersheds in South America: the Amazon, La Plata, and Orinoco basins. To evaluate potential impacts…

Frozen chicken for wild fish
OBJECTIVES: Amazonian populations are experiencing dietary changes characteristic of the nutrition transition. However, the degree of change appears to vary between urban and rural settings. To investigate this process, we determined carbon and nitrogen stable isotope ratios in fingernails and dietary intake of Amazonian populations living along a rural to urban continuum along the Solimões River in Brazil. METHODS: Carbon and nitrogen stable iso…
Agriculture in Brazil
Nutrient Imbalances in Agricultural Development
Nutrient additions to intensive agricultural systems range from inadequate to excessive—and both extremes have substantial human and environmental costs.
Transformation of the Nitrogen Cycle
Humans continue to transform the global nitrogen cycle at a record pace, reflecting an increased combustion of fossil fuels, growing demand for nitrogen in agriculture and industry, and pervasive inefficiencies in its use. Much anthropogenic nitrogen is lost to air, water, and land to cause a cascade of environmental and human health problems. Simultaneously, food production in some parts of the world is nitrogen-deficient, highlighting inequitie…
Geographical patterns of human diet derived from stable-isotope analysis of fingernails
Carbon and nitrogen isotope ratios of human fingernails were measured in 490 individuals in the western US and 273 individuals in southeastern Brazil living in urban areas, and 53 individuals living in a moderately isolated area in the central Amazon region of Brazil and consuming mostly locally grown foods. In addition, we measured the carbon and nitrogen isotope ratios of common food items to assess the extent to which these isotopic signatures…
