NEW YORK (CNN) – An international team & # 39; scientists have developed a diet that says you can & # 39; improve health while ensuring production of & # 39; sustainable food to reduce further damage to the planet.
The "power of pjanetarja 'diet is based on the reduction of red meat and sugar intake by half and making & # 39; fruit, vegetables and nuts are added.
And it & # 39; 11.6 million to prevent premature death without harming the planet, says the report published Wednesday in the medical journal The Lancet.
The authors warn that global change in diet and the production of & # 39; food is needed by 3 billion people worldwide are malnourished – including those who are below and lacks extra food – and -produzzjoni of & # 39; food is exceeding the environmental targets, manage climate change, biodiversity loss and pollution.
The world population is expected to reach 10 billion by 2050; that growth, combined with the current dietary habits and production of food, will "exacerbate the risks to people and the planet," according to the authors.
"The stakes are very high," said Dr. Richard Horton, editor of leading & # 39; The Lancet, by the findings of the report, noting that one billion people live hungry and 2 billion people eat too much of the wrong foods.
Horton believes that "nutrition has not yet managed to get the kind of & # 39; political attention given to diseases like AIDS, tuberculosis, malaria."
"Using the best available evidence" of & # 39; controlled feeding studies, randomized trials and large studies & # 39; cohort, the authors issued b & # 39; new recommendation, explained Dr. Walter Willett, main author of the paper and a professor of epidemiology and nutrition at Harvard T.H. Chan school of public health.
The report suggests five strategies to ensure that people can change their diets and do not harm the planet doing so: incentivising people to eat more b & # 39; health, global shift production to crops varied, intensifying & # 39; agriculture b & # 39; sustainable way, more stringent rules on governance & # 39; oceans and land, and reducing food waste.
To enable & # 39; a global population b & # 39; her health, the team & # 39; scientists created a diet & # 39; general reference, which they call "pjanetarja health diet," which is ideal plan & # 39; daily food for people who have more than 2 years, who believed that help reduce chronic diseases such as coronary heart disease, stroke and diabetes, as well as environmental degradation.
Diet break the best daily intake of whole grains, starchy vegetables, fruits, milk, proteins, fats and sugars, representing a total daily intake of 2500 calories.
They recognize the difficulty of the task, which will require changes in diet "substantial" global, requiring consumption & # 39; foods such as red meat and sugar decrease by & # 39; over 50 percent. In turn, consumption & # 39; nuts, fruits, vegetables and legumes has increased by & # 39; more than twice, the report says.
The diet advises people to consume 2,500 calories a day, which is slightly more than what people are eating today, Willett said. People should eat "variety & # 39; based food plant, low amounts of & # 39; based food animals, unsaturated fats rather than saturated, and few refined grains, highly processed foods and added sugar , "he said.
Regional differences are important to note. For example, countries in North America & # 39; Top eat almost 6.5 times the recommended amount of & # 39; red meat, while countries in the Asia & # 39; South eat 1.5 times the required amount of & # 39; starch vegetables.
"Almost all world regions bounding b & # 39; Substantial 'recommended levels & # 39; red meat, Willett said.
The benefits to health and the environment & # 39; changes in diet like they are known, "but, until now, the challenge of achieving diets from & # 39; sustainable food system has been hampered by lack of & # 39; guidelines on science-based, said Howard Frumkin, Chief of Biomedical UK charity research The Wellcome Trust program & # 39; s Planet our our Health. The Wellcome Trust funded research.
"It provides governments, producers and individuals with & # 39; point & # 39; starting-based evidence to work together to turn systems and our food culture", he said .
If the new diet has been adopted globally, 10.9 up to 11.6 million premature deaths could be prevented each year – equal to 19 per cent to 23.6 per cent of adult deaths. Reduction in sodium and increase whole grains, nuts, vegetables and fruits contributed the most to prevent deaths, according to one of the models of the report.
Some scientists are skeptical about whether the transfer of the global population for this diet can be achieved.
The recommended diet "is quite a shock" f & # 39; terms & # 39; as is feasible and how it should be implemented, said Alan Dangour, a professor of food and nutrition to overall health at the School & # 39 ; Hygiene and Tropical Medicine & # 39; London. What "immediately makes implementation difficult" is the fact that cross government departments need to work together, he said. Dangour was not involved in the report.
At the current level of production & # 39; food, diet of & # 39; Reference can not be achieved, said Modi Mwatsama, high scientific leadership (of & # 39; food, nutrition and health systems) in the Wellcome Trust. Some countries n & # 39; are able to grow enough food because they can, for example, do not have resilient surfaces, while in & # 39; other countries, not healthy food is promoted heavily, she said.
Mwatsama added that unless there are structural changes, such as subsidies to deviate from meat production, and environmental changes, such as limits on how much can & # 39; used in fertilizer, "will not see people reach this target. "
To populations can follow diet & # 39; reference, the report suggests five strategies, which subsidies are one option. They fall recommendation to ensure good governance of land systems and the ocean, for example by banning land clearing and removing subsidies for world fisheries, because they lead to overcapacity of the fleet Fishing-global.
Secondly, the report describes strategies such as more farmers an incentive to change production & # 39; food from bulk & # 39; just a diverse crop production & # 39; nutritious crops.
The authors suggest, and people encouraged to eat healthy through food food information should be made more accessible, low-income groups such campaigns should be supported by social protection to avoid ongoing malnutrition.
Fourth & # 39; approach suggests that when agricultural intensification must consider local conditions to ensure the best agricultural practices to region, and then produce the best crops & # 39 ;.
Finally, the team suggests that reducing food waste by improving the planning of harvest and market access in & # 39; countries with low and middle income, while improving the shopping habits -konsumaturi in high income countries.
Louise Manning, a professor of the resilience of the food chain and supply at the University Agricultural Royal, said that achieving the target of reducing food waste is "something very difficult to achieve" because it requires government, communities and individual households together.
However, "can & # 39; done," said Manning, who was not involved in the report, noting the use back the use of plastic f & # 39; countries like the UK.
The Agreement on Climate & # 39; 2015 in Paris aimed at limiting global warming to 2 degrees Celsius & # 39; above pre-industrial levels. The achievement of this goal m & # 39; longer just about the decarbonised energy systems by reducing fossil fuels, but also on food transition, said Johan Rockström, science professor environment in Stockholm Resilience Center, University of Stockholm, Sweden, study.
"This is urgent," he said. Without global adaptation dietary & # 39; reference, the world "will not succeed with the agreement & # 39; Paris Climate."
System & # 39; sustainable food production requires emissions & # 39; no greenhouse gas such as methane and nitrous oxide are limited, but methane is produced during the digestion of livestock while the nitrous oxides released from the ground and pastures. But the authors believe that these emissions are inevitable to provide healthy food for 10 billion people. They point out that the decarbonisation of the energy system of the world must move faster than anticipated, to accommodate it.
All & # 39; everything, ensuring population and planet b & # 39; health need to combine all strategies, the report concludes – a change in major diet, improved food production and technological changes, as well as reductions in food waste.
"The design and operation & # 39; sustainable food systems that provide healthy diets for a world population growing and rich presents a formidable challenge. Nothing less than a new global agricultural revolution," said Rockström, adding that 'solutions exist.
"It is about behavior change. It is about technology. It is about policy. It is about rules. But we know how to do it."
