Food Security And Nutrition

Cereals and their derivatives are the basis of human nutrition. However, cereals also contribute to the dietary exposure to toxic metals that may pose a risk. Strengthening food security and nutrition information is a high priority challenge for the Cape Verde Government. The toxic metals content (Cr, Ni, Sr, Al, Cd, Pb) has been determined in 126 samples of cereals and derivatives (rice, corn gofio, corn flour, wheat flour, corn, wheat) consumed in Cape Verde. Wheat flour samples stand out for registering the highest Sr (1.60 mg/kg), Ni (0.25 mg/kg) and Cr (0.13 mg/kg). The results show relevant Al levels (1.17 – 13.4 mg/kg) with its highest levels in corn gofio. The mean Pb average content in the cereals is 0.03 – 0.08 mg/kg with the highest level observed in corn gofio. The Al and Pb levels are lower in cereals without husks. A consumption of 100 g/day of corn gofio provide an intake of 1.34 mg Al/day (13.7% of the tolerable weekly intake established at 1 mg/kg bw/week) and 8 µg Pb/day (20% of the BMDL set at 0.63 µg/kg bw/day for nephrotoxic effects). The minimization of the dietary exposure of the Cape Verdean population to toxic metals is through the importation of higher quality cereals.

Consumption of cereals and cereal-based products represents 47% of the total food energy intake in Cape Verde. However, cereals also contribute to dietary exposure to metals that may pose a risk. Strengthening food security and providing nutritional information is a high-priority challenge for the Cape Verde government. In this study, toxic metal content (Cr, Ni, Sr, Al, Cd, and Pb) is determined in 126 samples of cereals and derivatives (rice, corn, wheat, corn flour, wheat flour, corn gofio) consumed in Cape Verde. Wheat flour samples stand out, with the highest Sr (1.60 mg/kg), Ni (0.25 mg/kg) and Cr (0.13 mg/kg) levels. While the consumption of 100 g/day of wheat would contribute to 13.2% of the tolerable daily intake (TDI) of Ni, a consumption of 100 g/day of wheat flour would contribute to 8.18% of the tolerable weekly intake (TWI) of Cd. Results show relevant Al levels (1.17–13.4 mg/kg), with the highest level observed in corn gofio. The mean Pb average content in cereals is 0.03–0.08 mg/kg, with the highest level observed in corn gofio. Al and Pb levels are lower in cereals without husks. Without being a health risk, the consumption of 100 g/day of wheat contributes to 17.5% of the European benchmark doses lower confidence limit (BMDL) of Pb for nephrotoxic effects; the consumption of 100 g/day of corn gofio provides an intake of 1.34 mg Al/day (13.7% of the TWI) and 8 µg Pb/day (20% of the BMDL for nephrotoxic effects). A strategy to minimize the dietary exposure of the Cape Verdean population to toxic metals from cereals should consider the continuous monitoring of imported cereals on arrival in Cape Verde, the assessment of the population's total diet exposure to toxic metals and educational campaigns.

<p>The levels of K, Ca, Fe, Zn, Cu, Mn, Pb, As, Cd, Cr, and Pb in commonly used medicinal herbs and their infusions by Lebanese were analyzed by EDXRF and ASS techniques, respectively. The order of metal contents in the herbs was found to be: K (6990-19850 ug/g) &gt; Ca(1630-14450 ug/g) &gt; Fe(80-3650 ug/g) &gt; Mn (28-458 ug/g) &gt; Zn (23-108 ug/g) &gt; Cu (5-71 ug/g) &gt; Cr (3.1-55 ug/g) Pb&gt; (1.1-10.3 ug/g) &gt; As (nd-10.8 ug/g) &gt; Cd (nd-1.7 ug/g). The mean levels of toxic metals in herbs Pb, As and Cd were below WHO permissible levels. Cluster analysis indicated metals are most probably in plants due to wastes disposal and irrigation with contaminated wastes and/or from atmospheric waste particulates. The levels of Mn, Cr, Pb and As in herbal infusions were found to be higher in soaked than boiled preparations and correlated with Fe, while Zn and Cu levels were higher in boiled infusions. The highest weekly intake from herbal infusions of toxic metals Cr (492.8 ug), As (77.0 ug), Pb (291.2 ug) and Cd (19.0 ug) were below the recommended permissible tolerable weekly intake respectively 1260 ug, 900 ug, 1500 ug, and 150 ug. Therefore, the consumption of these traditional medicinal herbs does not pose any health risk provided full compliance with recommended daily doses.<strong></strong></p>

THE EFFECT OF DIFFERENT FILLER ON pH, WATER CONTENT, FLAVOR AND ELASTICITY OF BEEF MEATBALL. This research was aimed to determine the effect of different fillers on pH, water content, flavor and elasticity of beef meatball. This study used Completely Randomized Design (CRD) with four treatments and four replicates at each treatment. The treatments were involving 15% concentration of different fillers (R) including: R1 = tapioca flour, R2= sagu flour, R3 = corn flour, and R4 = wheat flour. The Variables were pH, water content, flavor and elasticity. The mean difference was tested using BNJ Test. The results showed that the filler of each flour in beef meatball significantly affected (P<0.05) on flavor, but did not affect the pH value, water content and elasticity onthe beef meatballs. It was concluded that the use of wheat flour(high protein) produced the best meatball quality of flavors, very preferred by panelists.Key words: beef, meatball, fillers.

Changes to the global infrastructure have contributed to the growing (linguistic) diversity of large metropolises. However, there have been calls from scholars to explore “emerging superdiversity” (DePalma and Pérez-Caramés 2018) in peripheral regions in order to fully understand the complexities and nuances of the sociolinguistics of globalisation (Wang et al. 2014; Pietikäinen et al. 2016). This article, therefore, explores language ideologies among a purposive sample of five young adults of Cape Verdean origin living in the peripheral region of Galicia, Spain, and draws on interview data to examine the ways in which multilingual migrants engage with the language varieties in their linguistic repertoire. In studying immigration from a former African colony to a bilingual European context, we can see how language ideologies from the migrant community are reflected in local ones. The sociolinguistic dynamics of Cape Verde and Galicia share many similarities: both contexts are officially bilingual (Galician and Spanish in Galicia, Kriolu and Portuguese in Cape Verde), and questions regarding the hierarchisation of languages remain pertinent in both cases. The ideologies about the value and prestige of (minority) languages that Cape Verdean migrants arrive with are thus accommodated by local linguistic ideologies in Galicia, a region which has a history of linguistic minoritisation. This has important implications for the ways in which language, as a symbolic resource, is mobilised by migrants in contexts of transnational migration. The findings of this study show how migrants are key actors in (re)shaping the linguistic dynamics of their host society and how, through their practices and discourses, they challenge long-standing assumptions about language, identity and linguistic legitimacy, and call into question ethno-linguistic boundaries.

This article examines what is at stake when performers and playwright critically transfigure oral histories when staging them theatrically. Representations of race and colonial history are integral to a nation's conception of its own cultural identity. These issues are at the forefront of many theatre productions in Cape Verde, an intensely creolized West African nation whose islands bear traces of the Europeans and Africans who have commingled there for centuries. The article examines two performances rooted in Cape Verdean history that challenge existing theoretical paradigms for the mimetic relationship between actors and the historical personae they portray onstage. Proposing the concept of the ‘historical imagination’, it explores how theatre artists self-consciously alter the local history they circulate to an international theatre festival stage and, concomitantly, how the theatre festival context and media coverage profoundly impact how national history is told within a global performance arena.

The tall coconut palm was introduced in Brazil in 1553, originating from the island of Cape Verde. The aim of the present study was to evaluate the genetic diversity of ten populations of Brazilian tall coconut by 13 microsatellite markers. Samples were collected from 195 individuals of 10 different populations. A total of 68 alleles were detected, with an average of 5.23 alleles per locus. The mean expected and observed heterozygosity value was 0.459 and 0.443, respectively. The number of alleles per population ranged from 36 to 48, with a mean of 40.9 alleles. We observed the formation of two groups, the first formed by the populations of Baía Formosa, Georgino Avelino and São José do Mipibu, and the second by the populations of Japoatã, Pacatuba and Praia do Forte. These results reveal a high level of genetic diversity in the Brazilian populations.

The aim of the present study was to evaluate the contamination levels of some classes of persistent organic pollutants (POPs) in free-range hen eggs and to estimate the related human dietary exposure in a Site of National Interest (SNI), characterized by a serious state of environmental pollution (Bussi sul Tirino area, central Italy). For these purposes, 17 samples of free-range hen eggs collected in home-producing farms located in the SNI territory were analyzed for 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), 12 dioxin-like polychlorinated biphenyls (dl-PCBs) and 6 non-dioxin-like PCBs (ndl-PCBs). Dietary exposure was assessed assuming a standard consumption of eggs per week. The concentration of ∑PCDD/Fs + dl-PCBs ranged from 0.463 to 8.028 pg TEQ (Toxic Equivalent) g−1 fat, while the mean contamination level of the ∑ndl-PCBs ranged from 0.234 to 7.741 ng TEQ g−1 fat. PCDD/Fs and PCBs contamination levels were lower than maximum values established by the Commission Regulation (EU) 1259/2011, except for one sample. The estimated weekly intake (EWI), calculated in order to evaluate the contribution in terms of the monitored pollutants of the locally produced eggs to the diet, was lower than the tolerable weekly intake (TWI) established by the European Food Safety Authority (EFSA).

Colonial Empire

Having lost the war politically, with the independence of Guinea and the recognition of Guinean state by dozens of countries, Estado Novo was entering into a crisis of legitimacy. Members of the Portuguese military forces formed the Movement of Armed Forces, who lead the popular uprising against Marcelo Caetano on April 1974. The end of Estado Novo was not an automatic confirmation of the end of colonialism. But independence was inevitable. By the end of 1975, Portugal was no longer a colonial empire in Africa. Against Cabral’s desire, independence did bring the unity between Cope Verdeans and Guineans. Whereas Cape Verde was governed by an all- Cape Verdean government, Guinea had a few Cape Verdean in its government. The coup d’etat led by Nino Vieira against Cabral’s bother Luís Cabral has been considered the second death of Cabral.
