One hamburger a week, but no more. That's all people have to eat for their health and the planet, according to a report published on Wednesday that is trying to change the world's eating patterns.
The number of eggs must be limited to less than four weeks, said the report, and dairy products must be one serving a day, or less.
The report, prepared by a nutrition, agriculture and environment expert panel, recommended a diet consisting of vegetable-derived foods, with arguments supported by previously published studies that have linked red meat to an increased risk of health problems.
Another recent study shows how eating habits affect the environment. The production of red meat occupies land and food to raise livestock, which emits methane, a greenhouse gas.
John Ioannidis, president of disease prevention at Stanford University, He said he welcomed growing concern about how diets affect the environment, but the report's recommendations do not reflect the level of scientific uncertainty about nutrition and health.
"The proof is not as strong as it seems," he said.
This report was organized by EAT, a non-profit organization based in Stockholm that seeks to improve the food system, and published in medical journals Lancet.
The panel of experts who wrote it said that "the transformation of main foods" is needed in 2050 and that the ideal diet they make is flexible enough to adapt to food culture around the world.
Generally, This diet focuses on grains, nuts, fruits and most vegetables. He noted that adding sugar should be limited, processed grains such as white rice, and starches such as potatoes and cassava. He added that the average consumption of red meat had to be halved worldwide, although the changes needed varied according to region and the reduction had to be more drastic in rich countries, such as the United States.
However, Convincing people to limit their consumption of meat, cheese and eggs will not be easy, especially in places where the food is part of the culture.
In Sao Paulo, systems analyst Cleberson Bernardes said when leaving a restaurant that ate only one serving of red meat a week would be "ridiculous." While in Berlin, Erik Langguth craftsmen point out that there are better ways to reduce greenhouse gas emissions and reject the suggestion that the world reduces meat consumption.
"If there is no meat, it is not the right food," said Langguth, who comes from an area famous for its bratwurst sausage.
