Recent Trends in Dietary Habits of the Italian Population: Potential Impact on Health and the Environment.

Population growth, globalization, urbanization, and economic pressures are causing changes in food consumption all over the world. The study's aims are (1) to evaluate trends in food habits in Italy to highlight deviations from the traditional Mediterranean diet, (2) to analyze the features of the present Italian diet that should be modified to meet evidence-based global scientific targets for a healthy and sustainable diet proposed by the EAT-Lancet Commission. Trends in food availability for human consumption during the period 2000-2017 were assessed using the food balance sheets (FBSs). Greenhouse gas (GHG) emission was estimated according to life cycle assessment (LCA) analyses. During the study period, the availability of animal fat and beef meat greatly declined (-58% and -32%, respectively), followed by fruit, potatoes, vegetables, milk, and non-tropical oils (-20%, -15%, -13%, -14%, and -11%, respectively). A substantial increase has occurred for tropical oils, fish, and nuts (+156, +26%, and +21%, respectively). In order to meet the targets of consumption proposed by the EAT-Lancet Commission, the consumption of legumes and nuts should be almost doubled, whereas the consumption of meat, eggs, dairy products, animal fat, tropical oils, and sugars should be reduced by proportions ranging from 60% to 90%. If implemented, these changes would reduce the diet-related greenhouse gas emission by nearly 50%. In conclusion, these data call for nutritional education programs and interventions on the food system aimed at promoting a healthier and more environmentally sustainable diet. To this end, the availability and affordability of products with a better impact on human health and the environment should be promoted.

Molecular Characterisation of Aflatoxigenic and Non-Aflatoxigenic Strains of Aspergillus Section Flavi Isolated from Imported Peanuts along the Supply Chain in Malaysia.

Peanuts are widely consumed in many local dishes in southeast Asian countries, especially in Malaysia which is one of the major peanut-importing countries in this region. Therefore, Aspergillus spp. and aflatoxin contamination in peanuts during storage are becoming major concerns due to the tropical weather in this region that favours the growth of aflatoxigenic fungi. The present study thus aimed to molecularly identify and characterise the Aspergillus section Flavi isolated from imported peanuts in Malaysia. The internal transcribed spacer (ITS) and ß-tubulin sequences were used to confirm the species and determine the phylogenetic relationship among the isolates, while aflatoxin biosynthesis genes (aflR, aflP (omtA), aflD (nor-1), aflM (ver-1), and pksA) were targeted in a multiplex PCR to determine the toxigenic potential. A total of 76 and one isolates were confirmed as A. flavus and A. tamarii, respectively. The Maximum Likelihood (ML) phylogenetic tree resolved the species into two different clades in which all A. flavus (both aflatoxigenic and non-aflatoxigenic) were grouped in the same clade and A. tamarii was grouped in a different clade. The aflatoxin biosynthesis genes were detected in all aflatoxigenic A. flavus while the non-aflatoxigenic A. flavus failed to amplify at least one of the genes. The results indicated that both aflatoxigenic and non-aflatoxigenic A. flavus could survive in imported peanuts and, thus, appropriate storage conditions preferably with low temperature should be considered to avoid the re-emergence of aflatoxigenic A. flavus and the subsequent aflatoxin production in peanuts during storage.

Nut consumption in Spain and other countries.

In countries of the Mediterranean region, nuts have been consumed in moderate quantities since ancient times. Epidemiological studies show lower risk of cardiovascular diseases in populations with frequent nut consumption, independent from other dietary components. This article assesses nut consumption in Spain and other countries using different sources of data collected at the country, household or individual levels. The per capita consumption of nuts in Spain in 2001 was 7.9 g/person/d. The varieties most widely consumed are walnuts, almonds, hazelnuts and peanuts. Results of the eVe study estimate an average nut consumption in the Spanish population aged 25-60 years of 3.3 g/person/d. No significant statistical differences were observed between men and women. Consumption is higher in men aged between 35 and 44 years (4.5 g/d) and in women aged between 45 and 54 years (3.5 g/d). In the population of 2-24 years, according to the enKid study, nut consumption is estimated at 4.9 +/- 18.5 g/person per d. The age group with the highest consumption is teenagers between 14 and 17 years. The northeastern, northern and eastern regions of Spain show the highest consumption. According to FAO balance sheets, in 2001, Lebanon (16.5 kg/person per year) and Greece (11.9 kg/person per year) were the countries in the Mediterranean region with the highest consumption of nuts, followed by Spain (7.3 kg/person per year), Israel and Italy.
