Scientists have developed a diet that, in their opinion, will save millions of lives a year and prove to be sustainable for humans despite the threat of climate change.
The report published in a medical journal The Lancet could provide the livelihoods needed to feed 10 billion people if everyone adopted it by 2050, without causing serious damage to the planet.
This is the work of the non-profit organization EAT, based in Stockholm, including the work of 37 scientists who have been studying ways to reduce the impact of food consumption on the climate.
What are the key elements of food?
One of the suggestions is no surprise the red meat because meat production has a larger environmental impact per serving compared to other food groups, as well as more serious consequences for human health.
EAT says that red meat consumption should be limited to 98 g (or 3.4 oz) a week, so a quarter-pound hamburger. His research indicates that North America is by far the biggest consumer of red meat.
Current food consumption by food group and by continent.

The same is true for processed meat, added sugar, refined grains and starchy vegetables – potatoes – whose consumption should be considerably reduced.
He also advocates "low to moderate amounts" of seafood and poultry – while the human race is expected to double the amounts of vegetables, fruits, legumes and nuts that it eats.
As the climate has already changed due to historical greenhouse gas emissions, EAT estimates that this regime is expected to reduce the carbon footprint of food production, which currently accounts for 30% of global greenhouse gas emissions. 70% of the use of freshwater.
The study also states that the diet will prevent about 11 million deaths a year, thanks to a reduction in heart attacks, strokes and some cancers.
The regime to save the world
Here's what the EAT study says that humans should consume in a week.
– 3.4 oz. red meat (beef, pork, lamb)
– 7 oz of poultry
– 7 oz of seafood
– 1.5 lb. legumes (dried beans, lentils, peas, soya beans, peanuts)
– 3.8 lbs of dairy products (including milk and cheese)
– 4.6 lb. of vegetables
– 3.1 lb. of fruit
– 3.5 lb whole grains (rice, wheat, corn, etc. – dry weight)
– 12 oz of potatoes
– 7.6 oz sweeteners (sugar)
– 8 oz of nuts
– about 2 medium eggs
