British medical journal Lancet issued a proposal for a new diet, designed by around thirty scientists from 16 countries. They named it the "planetary health diet" and proposed changes in eating habits to maintain life on the planet. The most prominent point is the almost total suppression of meat in food, in a world that in thirty years will reach 10 billion people.
The diet states that if someone eats meat every day, they should limit their intake to no more than one hamburger per week or one barbecue per month. Scientists say that plants are a source of protein for consumption. That's why it is recommended to eat nuts and beans every day. And fruits and vegetables must be half of daily food.
According to research published on Lancet, in this way it will avoid the deaths of eleven million people per year, due to the reduction of diseases caused by unhealthy diets, heart attacks, strokes and various forms of cancer.
For researchers, a diet, which can serve to feed more people, goes hand in hand with reducing gas emissions, which prevents species extinction and water from being maintained. Although that alone is not enough: they suggest reducing half of the leftovers and increasing agricultural food production.
According to scientists, daily food must be as follows
Walnuts: 50 grams.
Beans, lentils, and other legumes: 75 grams.
Fish: 28 grams.
Eggs: 13 grams (one per week).
Meat: 14 grams of red meat and 29 grams of chicken.
Carbohydrates: 232 grams of grains (such as bread and rice) and 50 grams of vegetables rich in starch.
Dairy products: 250 grams (equivalent to a glass of milk).
Vegetables: 300 grams.
Fruits: 200 grams.
Sugar: 31 grams.
Oil: 50 grams.
For Walter Willet, from Harvard University, there will be no problem getting used to the taste. On the diet proposed with his colleagues, he said that "there are extraordinary variations there" and that they can be combined "in thousands of different ways", saying that "we are not talking about diets lacking", from "a healthy diet , flexible and fun ".
What changes should be made so that a "planetary health diet" can be applied? America and Europe must cut red meat on a large scale; Southeast Asia must do it without fish; and Africans do the same with vegetables with starch.
"Humans have never tried to change the food system at this scale and speed," said Line Gordon, a professor at the Stockholm Resilience Center, where the diet project was coordinated. "Whether it's fantasy or not, fantasy doesn't have to be bad, it's time to dream of a better world," he said, regarding the initiation that brought together 37 scientists.
Among those who participated were experts in agriculture, nutrition and climate change. His research work took two years. The taste of the recommended diet is nothing but saving lives. The world reached 7 billion people in 2011 and today there are an estimated 7700 million. By 2050 the figure is around 10 billion. Where the number is a problem in the first place.
