What is the planetary diet with which 10,000 million people could be fed?

January 19, 2019 – Promotes saving lives and feeding 10,000 million people without causing catastrophic damage to the planet.

The media have been dubbed "the planetary health diet" and this is a new proposal to protect the Earth from a group of more than 30 scientists from different areas from 16 countries around the world , published in the prestigious specialized magazine The Lancet.


  • The food that can improve and lengthen your life: are you eating it enough?

  • Why 2030 is the deadline of humanity to avoid a global catastrophe

Although this regime does not completely eliminate meat or dairy products, it requires a huge change in what we put in our dishes and go to foods that we just eat.

What changes should I make?

If you eat meat every day, then this is the first big step.

For red meat, you should reduce the dose to one hamburger a week or a large steak per month. And that would be all.

You can serve a couple of portions of meat or chicken a week, but it's the plants where the rest of your proteins should come from.

For this reason, researchers recommend new ones and a good portion of pulses (beans, chickpeas and lentils) every day.

Also eat all kinds of fruits and vegetables, which have to occupy half of each dish.

However, another of the sacrifices that are raised is linked to the reduction of starchy vegetables, such as potatoes or cassava, which is widely consumed in Africa and parts of the Caribbean and Latin America.

What is the diet in detail?

This should be its composition per day:


  • New. 50 gr

  • Beans, chickpeas, lentils and other pulses. 75 gr

  • Fish 28 gr

  • Eggs: 13 gr (equivalent to almost one per week)

  • Meat: 14 gr. Of red meat and 29 gr. Of chicken

  • Carbohydrates: 232 g of whole grains (such as bread and rice) and 50 g of starch-rich vegetables

  • Dairy products: 250 gr (equivalent to a glass of milk)

  • Vegetables: 300 gr, and fruits: 200 gr


The diet also enables the consumption of 31 grams of sugar and approximately 50 grams of oils such as olive oil.

Will the taste be awful?

Walter Willet, a researcher at Harvard University who participated in the study, said that we would not have problems with taste and that, after a childhood on a farm eating three portions of red meat a day, It is now quite in line with the planetary health diet.

"There's a tremendous variety there. You can take these foods and bring them together in thousands of different ways. We are not talking about a deprivation diet here, it's a healthy, flexible and enjoyable diet," he says.

Can it be applied to real life or is it just a fantasy?

This plan requires changes in diets in almost every corner of the world.

Europe and America would need to cut red meat massively; East of Asia, the fish, and Africa, the vegetables with starch.

"Humanity has never tried to change the food system at this scale and speed," says Line Gordon, assistant professor at the Resilience Center of Stockholm, an institution that coordinated the publication of the report.

"Whether it's a fantasy or not, a fantasy does not have to be bad … it's time to dream of a better world," he maintains.

To whom did this happen?

A group of 37 scientists from around the world gathered as part of the EAT-Lancet commission.

They are a mix of experts with knowledge ranging from agriculture to climate change and nutrition. It took two years to find the results that were recently published in the British medical journal The Lancet.

Will you save lives?

The world population reached 7,000 million in 2011 and is now about 7,700 million.


  • What is the flexural diet and why it is key to save the planet


It is expected that this figure will reach 10,000 million around 2050 and continue to rise.

One of the problems with this population increase is, precisely, how to feed them.

Researchers say the diet will prevent around 11 million people from dying every year.

This number is due in large part to the reduction of illnesses related to unhealthy diets, such as heart attacks, strokes and some types of cancer, the main causes of death in developed countries.

Can this diet save the planet?

The objective of the researchers was to present a diet that served as a basis for feeding more people, while minimizing greenhouse gas emissions, it avoids the extinction of the species and it is preserve the water.

However, the change in diet is not enough.

To make this result, you also have to halve food waste and increase the amount of food produced in current agricultural land

How bad is agriculture for the planet?

Matt McGrath, BBC's environment correspondent

The use of land for growing food and forestry accounts for around a quarter of the global greenhouse gas emissions, approximately the same as the # electricity and heating, and much more than all the trains, planes and automobiles on the planet.

When you look more closely at the environmental impact of the food industry, you can see that meat and dairy products are the main factors: worldwide, cattle represent between 14.5% and 18% of The emissions of greenhouse gases induced by the human being.

Agriculture is also one of the main contributors to methane and nitrous oxide emissions.

In addition, it is an important source of air pollution with the ammonia of farms, one of the main causes of fine particles, which, according to the World Health Organization, are a threat for health around the world.

In the same way, when it comes to water, agriculture and food production are one of the biggest threats, as they consume 70% of fresh water sources for to irrigation
