The association between animal flesh foods consumption and semen parameters among infertile Iranian men: a cross-sectional study

BackgroundPrevious studies have demonstrated the association between dietary patterns and semen quality indicators, but research on the possible association between animal flesh foods consumption and semen quality is limited. Therefore, this study was conducted to investigate the association between animal flesh foods consumption with semen quality.MethodsIn this cross-sectional study, 400 newly-identified (< 6 months) infertile men, as diagnosed by an andrologist, were recruited into the study. Dietary intake was assessed by using a semiquantitative Food Frequency Questionnaire. The total meat consumption was defined as the sum of red meat, poultry, fresh fish, canned fish, processed meats, and organ meats in the diet. A linear mixed model was used to assess the relationship between meat consumption and semen quality indicators of participants.ResultsConsumption of canned fish was inversely related to sperm immotility. Compared with the men in the lowest quartile of canned fish intake, those in the highest quartile had a lower sperm immotility [lowest quartile: 52.5%; (95% CI: 47–57) vs 47.4%; (95% CI: 43–51) P-trend = 0.026]. Similarly, a trend toward an inverse significant association between fresh fish intake and sperm immotility was observed (P-trend = 0.074). In contrast, fresh and canned fish intake was unrelated to other outcomes of sperm quality (P-trend > 0.05). No association was found between consumption of processed red meat, red meat, poultry, and organ meat, and semen quality indicators (P-trend > 0.05).ConclusionsWe found that consumption of canned fish is associated with a lower percentage of immotile sperm, whilst a high consumption of fresh fish increased the percentage of immotile sperm in Iranian infertile men. Further studies are recommended in this regard.

Fresh Fish Consumption Behaviour in Padang City, Indonesia

The fresh fish consumption behaviour has been attracting the previous researchers. Unfortunately, few studies based on Indonesia were held by the researchers. Due to the lack of the previous study, the purposes of the study are to investigate the influence of attitudes, control of perceived behaviour, and subjective norm on intention to consume fish, and to examine the relationship of the fish consumption intention with consumption behaviour. The study applies plan behaviour theory to understand the raised phenomena in this paper. The number of respondents participated in this study is fifty-five. SEM-PLS is used to analysis data supported by assessment of measurement and structural model as the smart-pls procedure. The results indicate that there is a positive effect of attitude toward behaviour on intention to consume fish. Besides, fish consumption intention also has a significant association with consume behaviour. However, the effect of the norm and control of perceived behaviour on fish consumption intention is not significant. This finding confirms the theory of plan behaviour. Practically, this finding shows implicitly that to increase the fish behaviour consumption, the intention to consume fish and attitude toward fish consume behaviour should be increased.

Les approvisionnements morutiers de la Guadeloupe durant la Seconde Guerre mondiale

During the Second World War, isolated in the absence of commercial relations with France, Guadeloupe used the peculiarities of its status as a French colony to continue to provide its population with essential cod from Saint-Pierre and Miquelon and Newfoundland and Labrador without its own commercial fleet. Although officially linked to Vichy France, Guadeloupe took advantage of the improbable agreements signed with the United States and, when administered by Free France, it&nbsp; collaborated with Newfoundland. To alleviate the shortage, the Guadeloupe authorities for the first time promoted the consumption of fresh fish as a substitute for cod.

Chlordecone and organochlorine compound levels in the French West Indies population in 2013-2014.

Agricultural activities in the Caribbean, especially banana cropping, are known for their significant use of pesticides. In particular is chlordecone, which was used between 1972 and 1993 against the banana root borer, Cosmopolites sordidus (Germar, 1824). In this context, "Kannari study: Health, Nutrition and Exposition to Chlordecone in French West Indies" was put in place in 2013-2014 to supplement knowledge about the exposure of the population to chlordecone and other organochlorine pollutants. The data collected comprised a dietary intake description, data from biological samples (blood sample), socioeconomic and demographic information, and data from complementary specific items relative to life habits. A total of 742 subjects (292 in Guadeloupe and 450 in Martinique) were included in the impregnation component of the Kannari study. In this study, chlordecone and organochlorine compounds were detected in almost all participants. This result suggests that exposure to chlordecone is widespread, but also to other organochlorine pesticides. Chlordecone impregnation of the majority of the population appears to have decreased between 2003 and 2013, but various subgroups of the population remain highly exposed. The levels of impregnation are determined by dietary exposure and environmental contamination. However, total consumption of fresh fish (all species combined), especially from informal channels, is the main source of exposure to chlordecone. The serum PCB concentrations measured in the French Caribbean Islands of Guadeloupe and Martinique are lower than those observed in metropolitan France in 2007 (French Nutrition and Health Survey (ENNS)). In contrast, the French West Indies population seems more exposed to lindane than the French mainland population, and this exposure also seems more recent.

Modified atmosphere packaging of fish – an impact on shelf life

The shelf life of fresh fish is short. Therefore, the fishing industry has always been willing to explore new technologies for shelf life extension. This paper will focus on one such technique, i.e., changing the nature of the gas surrounding the fish. The main purposes of modified atmosphere packaging of fish and fish products, but also other foodstuffs, are two-fold: to ensure the microbiological shelf life and the sensory quality of the product, including the colour, odour and palatability. During the last two decades, modified atmosphere packaging has become a dominant retail fish packaging technology. The main reasons for the development of modified atmosphere packaging are the continuous increase in fresh fish consumption, increases of urban populations and exhaustion of natural food resources. Developments in packaging materials and technologies have made the application of modified atmosphere packaging on a larger scale for fish and fish products feasible. In this paper, we present the basic principles of modified atmosphere packaging of fish, and the microbiological, sensory, chemical and physicochemical parameters that are important for the shelf life of fish packaged using this technology.

The relationship between forests and freshwater fish consumption in rural Nigeria.

Nigerians depend on fish for maintaining diverse and healthy diets. Fish are a key source of protein and micronutrients, both of which are important for healthy diets. Some research has shown that forests provide important ecosystem functions that support the productive capacity and sustainability of inland fisheries. Our study aims to empirically assess the relationship between forest cover around rivers and fish consumption. We use data from the Living Standards Measurement Survey (LSMS) and spatially merge household and village data with forest cover and river maps. We estimate the relationship between forest cover around rivers and average village fresh fish consumption, while also accounting for other socio-economic and geographical determinants. We find that that the density of forest cover around rivers is positively and significantly correlated with village consumption of fresh fish. Our results suggest that forests influence the consumption of fresh fish by improving the productivity of inland fisheries and increasing the availability of fish. Aquatic habitats tend to be overlooked in debates on land use and food production, and yet can be critically important sources of nutrient-rich foods that are limited in rural diets in developing countries, particularly for the poor. Clearing forests for agriculture in order to produce more agricultural crops might have the unintended consequence of reducing another important food source.

This study aims to: (1), Knowing the share of expenditure, the progress of prices of staple food and people's income in Central Halmahera Regency, (2), Analyzing the level of people's purchasing power with an indicator of the ratio of income to prices of staple foods in Central Halmahera Regency, and (3), Analyze the level of people's purchasing power with an indicator of the ratio of income to the index of staple food prices in Central Halmahera Regency. The results of the analysis show that the expenditure of community households in Central Halmahera Regency is specifically allocated to fulfill the consumption of fresh rice and fish, followed by consumption of flour, sugar and cooking oil. While the allocation of expenditures for consumption of staple-sourced staple foods includes chicken, milk, eggs and beef is still very low. The price of staple food in Central Halmahera Regency during the observation period of 2009 until 2018 in January - March, tends to increase in the range of 2% - 12%. Whereas on the other hand, the level of income of the community only changes in the range of 5% - 7%, with the highest income enjoyed by employees and entrepreneurs and conversely the lowest income is felt by farmers. The purchasing power of people in Central Halmahera Regency with an indicator of the ratio of income to each of the staple food prices tends to fluctuate but has experienced significant improvements in 2018 compared to 2009, except for the purchasing power measured as equal to beef consumption. The purchasing power equivalent to beef consumption has decreased to 22.32% because the percentage increase in income is less able to compensate for the increase in beef prices. Measured by the income ratio indicator on the basic food price index, people's purchasing power also showed an improvement in 2018 compared to 2009, but that only happened to farmers, construction workers, and civil servants groups I / II. When compared to 2017, public purchasing power in 2018 as a whole decreased by 12.38%. The purchasing power level of people in Central Halmahera Regency from the lowest ranking in sequence is felt by groups of farmers, followed by construction workers, civil servants groups I / II, entrepreneurs and employees.Â

La flota pesquera de altura y gran altura en el puerto de Barcelona. Una historia no contada (1907-1936).

The adoption of trawling was studied for different Spanish ports, but not for the port of Barcelona. This has led to the consideration that the fishing fleet based there was minor. However, in this paper a study on the number moored vessels and businesses tied to their management is performed. Thus, it is concluded that, although from the 1930s it may have ceased to be representative, it was not until that date. Between 1907 and the years before the Civil War the port of Barcelona had one of the largest and most modern fleets in the Peninsula, covering an important part of the consumption of fresh fish in the city. Likewise, companies in charge of its management were also involved in distribution activities.

Total Diet Study approach in estimating mercury and cadmium levels using selected fish: A case study from Sri Lanka

Total Diet Study (TDS) is a world-recognized approach in quantifying nutrients and contaminants in complete diets. In the present study, the TDS approach was used to determine the dietary exposure to mercury (Hg) and cadmium (Cd) by regular consumption of yellowfin tuna (YFT), swordfish (SWF) and sardinella (SAF) fish in Gampaha district, Sri Lanka. The study was based on the TDS method established by the World Health Organization (WHO). Hg and Cd were analyzed using Atomic Absorption Spectrophotometer after microwave digestion of samples. Survey results revealed that the weekly average fresh fish consumption was 301 g per person. Hg and Cd levels were calculated on the wet weight basis. The maximum allowable limits of Hg and Cd were compared with European Union/European Commission (EU/EC) regulation limits for each species. None of the samples exceeded the EU/EC maximum limit for Cd, but two samples of SWF exceeded the maximum limit for Hg, recommended by the EU/EC. The Provisional Tolerable Weekly Intake (PTWI) for Hg was calculated for risk assessment. The percentage contributions of SWF, YFT, and SAF for PTWI-Hg were 64.92 and 40.16 and 8.55 respectively. Accordingly, the SWF were close to exceed the PTWI value. YFT and SWF are considered as the top predators in the marine food web. Cooking did not significantly reduce the Hg and Cd contents in selected fish species. Further studies are recommended to evaluate the PTWI values for predatory fish species before consumption.

Fish and Fishing in the Roman World

This article focuses on two aspects related to fish and fishing. It first discusses the social context for the consumption of preserved and fresh fish, showing that generally consumption of certain types of fresh fish conferred status, whereas consumption of preserved fish, being more affordable, was attested across social strata. The article then moves on to examine the organisation of the ‘fishing industry’, specifically the relationship between fish-salting establishments and the fishermen who provided the fish. Although we have many literary, documentary, and archaeological sources for fish preservation and fishing techniques in classical antiquity, the fishermen engaged in large-scale fishing remain rather elusive.

Agility in the Factors Effecting the Quality and Safety of Fish Products

The consumption of fish by humans worldwide is 77%. The demand and consumption of fresh fish has significantly grown during recent years. The future growth is from aquaculture as the global demand for fish continuous to increase. The supply chain of fish is a network which consists of the fishermen, middlemen, distributors, transporters, storage facilities, suppliers, retailers, delivery and selling the product to the consumer. It is necessary to maintain the quality and safety of fish/fish products till the time of consumption by the consumer. The quality and safety of the fish/ fish products may deteriorate due to variations in temperature, distribution channel, transportation, packaging and grading. The purpose of this paper is to understand the impact of these factors on the quality and safety of the fish/fish products and to propose the implementation of the concept of agility into these factors so that the quality and safety of these products is ensured with minimum losses and wastage.

Comparative Analysis of Disparity in Demand for Fresh Fish between Rural and Urban Households in Cameroon

The past decades have exhibited changes in the consumption of fresh fish. In developing countries, factors affecting fish consumption are different between urban and rural households. This study comparatively analyses the disparity in demand for fresh fish between rural and urban households in Cameroon. Using random sampling, data on the weekly consumption of fresh fish were collected between April and May 2015; 30 households lived in rural localities while 30 lived in urban areas of Buea Municipality. Consumer’s income, the price of fresh fish, family size, gender and age of consumers represented parameters of interest. These were analyzed using the independent sample t-test. Results revealed that the availability, the income level and price affected fish consumption of rural dwellers while price, taste, income and affordability determined the consumption patterns of urban dwellers. The study equally revealed that the higher the price of fresh fish, the higher the demand for its closed substitutes and the higher the size of the household, the higher the quantity demanded. Gender, education and marital status did not affect the quantity demanded; family size and age negatively influenced consumers’ decision to buy while consumers’ income and price of fresh fish positively influenced consumers’ weekly and monthly expenditure on fresh fish. The study proposes that more information be provided to consumers regarding the numerous nutritional benefits of fresh fish for both rural and urban dwellers. Also, policy makers and marketers need to improve the availability of fresh fish in rural and semi-urban settings.

Comparison of the effect of omega-3 supplements and fresh fish on lipid profile: a randomized, open-labeled trial

BackgroundDietary fish is a rich source of Omega-3 poly-unsaturated fatty acids (PUFAs). These compounds may have protective effect against cardiovascular events possibly by modifying lipid profiles. Consequently, fish oil supplements are produced commercially to complement low fish intake. It is not clear if both interventions have similar effects. The aim of this trial was to compare the anti-hyperlipidemic effect of omega3 fatty acid supplements with fresh fish.MethodA total of 106 patients with hyperlipidemia were randomized. One group received 2 g/day of omega-3 capsules for a period of 8 weeks and the other group received a mean of 250 g trout fish twice weekly (for dinner and lunch) for the same time period. The effects of these diets on the lipid profile after the intervention were compared between the two groups.ResultsData from 48 patients in fish oil group and 47 patients from fish group was used for final analysis. In both groups, total cholesterol, non-HDL cholesterol, triglyceride (TG) levels, and Castelli I index (total cholesterol/HDL ratio) were reduced significantly following the treatment; however, dietary-fish intake had a more pronounced effect (−85.08 ± 74.82 vs. −30.75 ± 89.00, P < 0.001; 75.06 ± 35.43 vs. −16.93 ± 40.21, P < 0.001; −66.55 ± 30.79 vs. −12.7 ± 35.48, P = 0.003; and −0.77 ± 1.39 vs. −3.02 ± 1.85, P < 0.001; respectively). HDL level was increased in both groups with a higher effect in dietary fish group (4.47 ± 7.83 vs. 8.51 ± 8.79, P = 0.022). Atherogenic (Log [TG/HDL ratio]) and Castelli II (LDL/HDL ratio) indices did not change in fish oil group while were reduced significantly by fresh fish consumption (−0.04 ± 0.27 vs. −0.26 ± 0.17, P < 0.001; and 0.15 ± 0.7 vs. -1.32 ± 1.15, P < 0.001, respectively). LDL level was increased in the supplementation group, while it was significantly reduced in the dietary-fish group (+18.7 ± 24.97 vs. −22.75 ± 27.28, P < 0.001).ConclusionConsumption of fresh fish seems to be superior in positively modifying the lipid profiles which may have important translations in the occurrence of cardiovascular events.

Investigating the association between diet and risk of head and neck cancer in Taiwan.

Most studies reporting an inverse association between the consumption of vegetables and fruits and head and neck cancer (HNC) risk were conducted in Western populations and only a few included East Asians. The current case-control study investigated the association between diet and HNC risk using data of 838 HNC cases and 998 controls from a case-control study of HNC conducted in Taiwan. Each participant was asked about their consumption of fresh vegetables, pickled vegetables, fresh fruits, citrus fruits, meat, processed meat, fish, egg, and dairy products. Unconditional logistic regression was performed to estimate the odds ratio (OR) and 95% confidence interval (CI) of HNC risk associated with each food category, adjusted for sex, age, education, and use of alcohol, betel quid and cigarette. An inverse association was observed between HNC risk and daily intake of fresh vegetables (OR = 0.44, 95% CI: 0.20-0.95, p-trend = 0.002) or fruits (OR = 0.55, 95% CI: 0.43-0.72, p-trend = 0.00001). Individuals who did not consume fresh fruits and vegetables daily had more than double the risk of HNC compared to those with daily intake of vegetables and fruits (OR= 2.24, 95% CI: 1.54-3.25). The results of the current study supported an inverse association between the consumption of fresh vegetables and fruits and HNC risk. In addition to cessation of cigarette smoking and betel quid chewing and reduction of alcohol drinking, a public health campaign for preventing the occurrence of HNC should promote a healthy diet that contains plenty of fresh vegetables and fruits.

Are concentrations of alkaline earth elements in maternal hair associated with risk of neural tube defects?

The relationship between maternal intake of alkaline earth elements (AEEs) during the period of neural tube closure and the risk of neural tube defects (NTDs) is still unclear. We propose that AEE deficiency during the early period of pregnancy is associated with an elevated risk of NTDs in the offspring. In this study, we recruited 191 women with NTD-affected pregnancies (cases) and 261 women who delivered healthy infants (controls). The concentrations of four AEEs (Ca, Mg, Sr, Ba) in maternal hair sections that grew during early pregnancy were analyzed. Information on the dietary habits of the mothers was also collected by questionnaire. Higher concentrations of the four AEEs in hair had protective effects against the risk of total NTDs, with odds ratios with 95% confidence interval (comparing groups separated by each median level) of 0.44 (0.28–0.68) for Mg, 0.56 (0.36–0.87) for Ca, 0.45 (0.28–0.70) for Sr, and 0.41 (0.26–0.65) for Ba. Significant negative dose-response trends were identified for the relationships between the four AEE concentrations in maternal hair and the risks of anencephaly and spina bifida, but not for encephalocele. The frequencies of maternal consumption of fresh green vegetables, fresh fruit, and meat or fish were positively correlated with the concentrations of AEEs in hair. We concluded that the maternal intake of AEEs may play an important role in preventing NTD formation in offspring, and that this intake is related to maternal dietary habits of consuming fresh green vegetables, fresh fruit, and fish or meat.

Wild-Caught Versus Farmed Fish – Consumer Perception

Abstract We have limited knowledge of determinants of consumer preferences for wild-caught versus farmed-raised fish, so this work aims to investigate the impact of sociodemographics, habits and frequency of fresh fish consumption, such as involvement in cooking, on the preferences for wild versus farmed fish. A survey was done on a sample of 1151 fish consumers in Croatia. Results showed that female, older consumers, consumers with higher income and those living in coastal parts of Croatia give higher preferences for wild fish and they detect differences between the taste of wild and farmed fish. Consumers with higher levels of habits of fresh fish consumption, who eat fresh fish often and are more involved in cooking, prefer wild-caught fish. These findings provide valuable information for the aquaculture sector, especially for planning marketing strategies for the promotion of farmed fish.

Health risk assessment for the consumption of fresh and preserved fish (Alosa agone) from Lago di Como (Northern Italy)

BackgroundAlthough banned in many countries for decades, DDTs and PCBs still represent a global threat to food safety. As these contaminants are still present in aquatic ecosystems, fish can be an important contributor to their total dietary intake. ObjectivesAlosa agone specimens were sampled over a period of 10 years (from 2006 to 2015) to provide a representative overview of the DDT and PCB levels of Lago di Como, a deep Italian lake where a DDT input due to secondary sources was observed in recent years. The potential health risk from the consumption of both fresh and preserved fish was evaluated. ResultsWhile DDT levels have generally decreased during the monitored period, reaching quite stable levels, PCB concentrations were variable, with values exceeding, in some cases, the European Union limit for human consumption and enabling potential carcinogenic effects. However, typical local processing of this fish species markedly appeared to decrease these contaminant levels, thus making the fish product (called missoltino) a safer food. ConclusionsThe results of this work highlighted the need of continuous biomonitoring of those contaminants considered a past issue along with the emergent ones.

Accounting for structural changes in demand for foods in the presence of age and cohort effects: the case of fresh fish in Japan

Several studies indicate that not only age but also cohort effects exist in consumption of selected food products, although the latter are rarely explicitly specified in the ordinary econometric analyses of food consumption. These two demographic variables are significant in magnitude and often differ in pattern. Where the population is aging rapidly, as in Japan and Korea, it is inevitable that “structural changes” take place in the demand for certain products, because of the change in the composition of consumers. In this article, we first derive individual consumption of fresh fish, traditionally a major source of animal protein in Japan, by age from the Family Income and Expenditure Survey, where the original data are classified by age groups of household head. A cohort table based on the individual consumption estimates is then decomposed into age, cohort and period effects first and then the period effects are regressed against prices and income to determine the economic demand elasticities. We also attempted an alternative approach: a cohort analysis augmented with economic variables, to determine economic demand elasticities in one step. Even after age, cohort, price, and income effects are accounted for, non-negligible residuals remain unexplained, which may need interdisciplinary investigations.
