A global shift towards a vegan diet is vital to save the world from hunger, fuel poverty and the worst impacts of climate change, a UN report said today.
As the global population surges towards a predicted 9.1 billion people by 2050, western tastes for diets rich in meat and dairy products are unsustainable, says the report from United Nations Environment Programme's (UNEP) international panel of sustainable resource management.
It says: "Impacts from agriculture are expected to increase substantially due to population growth increasing consumption of animal products. Unlike fossil fuels, it is difficult to look for alternatives: people have to eat. A substantial reduction of impacts would only be possible with a substantial worldwide diet change, away from animal products."
Professor Edgar Hertwich, the lead author of the report, said: "Animal products cause more damage than [producing] construction minerals such as sand or cement, plastics or metals. Biomass and crops for animals are as damaging as [burning] fossil fuels."
The recommendation follows advice last year that a vegetarian diet was better for the planet from Lord Nicholas Stern, former adviser to the Labour government on the economics of climate change. Dr Rajendra Pachauri, chair of the UN's Intergovernmental Panel on Climate Change (IPCC), has also urged people to observe one meat-free day a week to curb carbon emissions.
The panel of experts ranked products, resources, economic activities and transport according to their environmental impacts. Agriculture was on a par with fossil fuel consumption because both rise rapidly with increased economic growth, they said.
Ernst von Weizsaecker, an environmental scientist who co-chaired the panel, said: "Rising affluence is triggering a shift in diets towards meat and dairy products - livestock now consumes much of the world's crops and by inference a great deal of freshwater, fertilisers and pesticides."
Both energy and agriculture need to be "decoupled" from economic growth because environmental impacts rise roughly 80% with a doubling of income, the report found.
Achim Steiner, the UN under-secretary general and executive director of the UNEP, said: "Decoupling growth from environmental degradation is the number one challenge facing governments in a world of rising numbers of people, rising incomes, rising consumption demands and the persistent challenge of poverty alleviation."
The panel, which drew on numerous studies including the Millennium ecosystem assessment, cites the following pressures on the environment as priorities for governments around the world: climate change, habitat change, wasteful use of nitrogen and phosphorus in fertilisers, over-exploitation of fisheries, forests and other resources, invasive species, unsafe drinking water and sanitation, lead exposure, urban air pollution and occupational exposure to particulate matter.
Agriculture, particularly meat and dairy products, accounts for 70% of global freshwater consumption, 38% of the total land use and 19% of the world's greenhouse gas emissions, says the report, which has been launched to coincide with UN World Environment day on Saturday.
Last year the UN's Food and Agriculture Organisation said that food production would have to increase globally by 70% by 2050 to feed the world's surging population. The panel says that efficiency gains in agriculture will be overwhelmed by the expected population growth.
Prof Hertwich, who is also the director of the industrial ecology programme at the Norwegian University of Science and Technology, said that developing countries – where much of this population growth will take place – must not follow the western world's pattern of increasing consumption: "Developing countries should not follow our model. But it's up to us to develop the technologies in, say, renewable energy or irrigation methods."
http://luben.tv/stream/76471Το μπέικον σας έφταιγε: “40% παραπάνω πιθανότητα οι vegan για καρκίνο παχέος” έδειξε έρευναΥπάρχει η γενικότερη άποψη πως οι άνθρωποι που επιλέγουν να ακολουθήσουν δια βίου μια vegeterian διατροφή γλυτώνουν πολλές επιβαρύνσεις στην υγεία τους σε σχέση με όσους επιμένουν σε μια ζωή με κατανάλωση κρέατος. Το μύθο αυτό είχε έρθει να καταρρίψει η παρατήρηση πως οι δια βίου βήγκανς έχουν 40% παραπάνω πιθανότητα να εμφανίσουν καρκίνο του παχέος εντέρου και του ορθού σε σχέση με τα σαρκοφάγα (κόντρα στην αντίθετη πεποίθηση που ίσχυε για χρόνια). Μια έρευνα του Πανεπιστημίου του Cornell ρίχνει φως στην υπόθεση κι εξηγεί το γιατί

Long term vegetarianism can lead to genetic mutations which raise the risk of heart disease and cancer, scientists have found.
Populations who have had a primarily vegetarian diet for generations were found to be far more likely to carry DNA which makes them susceptible to inflammation.
"Changes in the dietary Omega 6 to Omega 3 balance may contribute to the increase in chronic disease seen in some developing countries,” added Dr Brenna.
“The message for vegetarians is simple. Use vegetable oils that are low in omega-6 linoleic acid such as olive oil.”

The vegetarian allele evolved in populations that have eaten a plant-based diet over hundreds of generations. The adaptation allows these people to efficiently process omega-3 and omega-6 fatty acids and convert them into compounds essential for early brain development and controlling inflammation. In populations that live on plant-based diets, this genetic variation provided an advantage and was positively selected in those groups.
https://www.ncbi.nlm.nih.gov/pubmed/24343044Population-based studies report a beneficial health effect and a lower mortality rate for diets rich in fruits and vegetables. Therefore, the aim of our study was to analyze differences between various forms of diet and health-related variables. The sample for this study was taken from the Austrian Health Interview Survey 2006/07 (N = 15,474). Multivariate analyses of variance adjusted by sex, age, and socioeconomic status (SES) were conducted to examine health-related behavior, health, and quality of life depending on different forms of diet. Additionally, differences in the SES and body mass index (BMI) were analyzed. Our results show that a vegetarian diet is associated with a better health-related behavior, a lower BMI, and a higher SES. Subjects eating a carnivorous diet less rich in meat self-report poorer health, a higher number of chronic conditions, an enhanced vascular risk, as well as lower quality of life. In conclusion, our results have shown that consuming a diet rich in fruits and vegetables is associated with better health and health-related behavior. Therefore, public health programs are needed for reducing the health risks associated with a carnivorous diet.
https://www.ncbi.nlm.nih.gov/pmc/articl ... n_sectitlePopulation-based studies have consistently shown that our diet has an influence on health. Therefore, the aim of our study was to analyze differences between different dietary habit groups in terms of health-related variables. The sample used for this cross-sectional study was taken from the Austrian Health Interview Survey AT-HIS 2006/07. In a first step, subjects were matched according to their age, sex, and socioeconomic status (SES). After matching, the total number of subjects included in the analysis was 1320 (N = 330 for each form of diet – vegetarian, carnivorous diet rich in fruits and vegetables, carnivorous diet less rich in meat, and carnivorous diet rich in meat). Analyses of variance were conducted controlling for lifestyle factors in the following domains: health (self-assessed health, impairment, number of chronic conditions, vascular risk), health care (medical treatment, vaccinations, preventive check-ups), and quality of life. In addition, differences concerning the presence of 18 chronic conditions were analyzed by means of Chi-square tests. Overall, 76.4% of all subjects were female. 40.0% of the individuals were younger than 30 years, 35.4% between 30 and 49 years, and 24.0% older than 50 years. 30.3% of the subjects had a low SES, 48.8% a middle one, and 20.9% had a high SES. Our results revealed that a vegetarian diet is related to a lower BMI and less frequent alcohol consumption. Moreover, our results showed that a vegetarian diet is associated with poorer health (higher incidences of cancer, allergies, and mental health disorders), a higher need for health care, and poorer quality of life. Therefore, public health programs are needed in order to reduce the health risk due to nutritional factors.
Αναρωτιέμαι με ποια λογική λειτούργησαν οι δικαστές. Είναι γεγονος ότι η λέξη αφορά το γάλα που βγαίνει από τους αδένες των θυλαστικών. Όμως η λέξη γάλα είναι ήδη αποδεκτή για τους χρήστες του προϊόντος και δεν τίθεται θέμα προστασίας του καταναλωτή, μια και οι χρήστες του προϊόντος το προτιμούν ακριβώς γιατί είναι φυτικό.Τα αμιγώς φυτικά προϊόντα δεν μπορούν, καταρχήν, να διατίθενται στην αγορά με ονομασίες όπως «γάλα», «κρέμα γάλακτος», «βούτυρο», «τυρί» ή «γιαούρτι».
Αυτό αποφάνθηκε σήμερα το Ευρωπαϊκό Δικαστήριο επισημαίνοντας ότι τις ανωτέρω ονομασίες, το δίκαιο της ΕΕ τις προβλέπει αποκλειστικά για προϊόντα ζωικής προέλευσης.
Επίσης, αυτό ισχύει αν οι ονομασίες αυτές συμπληρώνονται από διευκρινιστικές ή περιγραφικές ενδείξεις που αναφέρουν τη φυτική προέλευση του επίμαχου προϊόντος, τονίζει στην απόφασή του το Ευρωπαϊκό Δικαστήριο, σημειώνοντας πάντως ότι με βάση το Ευρωπαϊκό Δίκαιο υπάρχει και κατάλογος εξαιρέσεων.
