A group of scientists developed a diet by reducing the number of deaths and providing food to 10 billion people, all without causing catastrophic damage to the planet.
Scientists have tried to explore how to feed billions more people over the next few decades.
Their answer was: "Planetary health plan", which does not completely exclude meat and milk.
But this system requires a huge shift, from what we accumulate in our dishes, to the foods we barely eat.
What changes should be made?
If you eat meat every day, it's the first hurdle. For red meat, you can eat a piece of burger once a week or a big steak during the month, that's a maximum.
But you can eat a range of "starchy vegetables", such as potatoes or cbadava, which are widely eaten in Africa.
So what is the diet in detail?
If you stick to this system, that's all you can do every day:
Nuts: 50 grams a day.
2 – beans, lentils and other legumes: 75 grams.
Fish: 28 grams.
4- eggs: 13 grams.
5. Meat: 14 grams for red meat and 29 grams of chicken meat.
6. Carbohydrates: 232 grams for cereals such as bread and rice and 50 grams for starchy foods.
7 – Milk: 250 grams, or equivalent to a cup of milk.
9. Vegetables: 300 g, fruits 200 g.
The diet also extends to 31 grams of sugar and about 50 grams of oils such as olive oil.
Would it have a terrible taste?
Professor Walter Willett, a researcher at Harvard, says this is not the case. After his childhood on a farm, he ate three slices of meat a day, becoming largely compatible with the planet's diet.
"There is a great diversity in this diet, you can take these foods and mix them in a thousand different ways," he said.
Who invented this system?
A group of 37 scientists from around the world, members of the Lancet Medical Committee's EAT-Lancet Committee, helped design the scheme.
These scientists are a mix of agricultural scientists, climate change and nutrition. It took them two years to reach their conclusions, published in the Lancet.
Will it reduce deaths?
The researchers say the system will save the lives of about 11 million people, who die each year.
This figure is due to the expected decrease in the number of people suffering from diseases caused by unhealthy diets, such as heart disease, stroke and certain types of cancer.
These diseases are the most deadly in developed countries.
So will this system save the planet?
The scientists aim to feed more people, including:
– Reduce greenhouse gas emissions as much as possible.
– Prevent the extinction of any species of living organism endangered.
– lack of expansion of agricultural land.
– water conservation.
But it's not enough to change diets.
To achieve this goal, it is also necessary to halve food losses and increase the amount of food produced from the current agricultural area.
