“…There again, the first 1,000 days after conception is a period of particular vulnerability, and some studies in French Guiana identified specific neurological and neuropsychological deficits in Amerindian children that were consistent with known targets of mercury neurotoxicity ( 34 ). More recently, the importance of exposure to lead has been revealed, with lead from hunting cartridges or Cassava and other tubers concentrating lead from the soil being suspected, but the sources of such widespread exposure are still being investigated ( 39 , 40 ). Approximately 25% of pregnant women in western French Guiana displayed blood lead levels of ≥50 μg/L and 5% ≥100 μg/L.…”

In French Guiana, life expectancy is between 2 and 3 years below that of France, reflecting differences in mortality rates that are largely sensitive to primary healthcare and thus preventable. However, because poverty affects half of the population in French Guiana, global measurements of life expectancy presumably conflate at least two distinct situations: persons who have similar life expectancies as in mainland France and persons living in precariousness who have far greater mortality rates than their wealthier counterparts. We thus aimed to synthesize what is known about statistical regularities regarding exposures and sketch typical French Guiana exposomes in relation to health outcomes. We conducted a narrative review on common exposures in French Guiana and made comparisons between French Guiana and mainland France, between rich and poor in French Guiana, and between urban and rural areas within French Guiana. The most striking fact this panorama shows is that being a fetus or a young child in French Guiana is fraught with multiple threats. In French Guiana, poverty and poor pregnancy follow-up; renouncing healthcare; wide variety of infectious diseases; very high prevalence of food insecurity; psychosocial stress; micronutrient deficiencies; obesity and metabolic problems; and frequent exposure to lead and mercury in rural areas constitute a stunningly challenging exposome for a new human being to develop into. A substantial part of the population’s health is hence affected by poverty and its sources of nutrition.

“…Such activities have led to mercury contamination in fish caught in the Oyapock River [145][146][147]. Furthermore, high lead levels detected in blood have been associated with the consumption of couac and other products derived from cassava, as well as big game [148,149], though the origin of this environmental contaminant has yet to be determined. Concerns associated with lead poisoning are particularly real among the inhabitants of the villages of the Oyapock [149,150], who still partially depend on hunting and fishing products, as well as cassava-derived products.…”

This is all the truer for the Palikur, who also depend on these modes of subsistence and whose cultivation and consumption of cassava still define their identity [89].…”

Local Food Systems under Global Influence: The Case of Food, Health and Environment in Five Socio-Ecosystems

et al. 2023

Globalization is transforming food systems around the world. With few geographical areas spared from nutritional, dietary and epidemiological transitions, chronic diseases have reached pandemic proportions. A question therefore arises as to the sustainability of local food systems. The overall purpose of this article is to put in perspective how local food systems respond to globalization through the assessment of five different case studies stemming from an international research network of Human-Environment Observatories (OHM), namely Nunavik (Québec, Canada), Oyapock (French Guiana, France), Estarreja (Portugal), Téssékéré (Senegal) and Littoral-Caraïbes (Guadeloupe, France). Each region retains aspects of its traditional food system, albeit under different patterns of influence modelled by various factors. These include history, cultural practices, remoteness and accessibility to and integration of globalized ultra-processed foods that induce differential health impacts. Furthermore, increases in the threat of environmental contamination can undermine the benefits of locally sourced foods for the profit of ultra-processed foods. These case studies demonstrate that: (i) the influence of globalization on food systems can be properly understood by integrating sociohistorical trajectories, socioeconomic and sociocultural context, ongoing local environmental issues and health determinants; and (ii) long-term and transverse monitoring is essential to understand the sustainability of local food systems vis-à-vis globalization.
