Chronic Diseases: Chronic Diseases and Development 2 Health, agricultural, and economic effects of adoption of healthy diet recommendations

Transition to diets that are high in saturated fat and sugar has caused a global public health concern as the pattern of food consumption is a mayor modifiable risk factor for chronic non-communicable diseases Although agri food systems are intimately associated with this transition, agriculture and health sectors are largely disconnected in their priorities policy, and analysis with neither side considering the complex inter relation between agri trade patterns of food consumption health, and development We show the importance of connection of these perspectives through estimation of the effect of adopting a healthy diet on population health, agricultural production trade the economy and livelihoods, with a computable general equilibrium approach on the basis of case studies from the UK and Brazil we suggest that benefits of a healthy diet policy will vary substantially between different populations, not only because of population dietary intake but also because of agricultural production trade and other economic factors

Microcystin-LR in Brazilian Aquaculture Production Systems

The growth of aquaculture production systems, mostly the sport-fishing kind, coupled with a lack of control, brings about concerns on the quality of water and food produced. The current paper determines which factors may trigger the growth of cyanobacteria, with subsequent concentrations of microcystins in collected water samples, at the surface and in the water column, from 10 aquaculture systems, during the dry and rainy seasons. The above is undertaken by measurements of biotic (counting of Chlorophyceae, cyanobacteria, and microcystin-LR [MC-LR]) and abiotic (total nitrogen and total phosphorus) factors. Because the water from the 10 aquaculture production systems had MC-LR concentrations that were highly correlated with Microcystis aeruginosa (M. aeruginosa) biomass, most MC-LR microcystins were produced by this species. The MC-LR concentrations and M. aeruginosa counting were positively correlated with nitrogen-to-phosphorus ratios and suggest that parameters may affect not only the M. aeruginosa biomass, but also MC-LR concentrations.
