Surely you did not expect it, because we fear that yes, this healthy nut that gives you vitamins, minerals and good fats. Why does it appear in this ranking? Because It is one of the foods that needs more water for its cultivation and being one of the most demanded nuts, with crops in quite dry areas, the water cost in each harvest is brutal.

Palm oil

It has been demonized for some time, but not only is it an ingredient that can be harmful to health, it is also damaging the planet. The palm plantations settle in lands that were originally jungle. The result of this deforestation is a loss of biodiversity with its corresponding and unfortunate extinction of species.


The production of palm oil in addition causes CO2 emissions into the atmosphere which, together with the indiscriminate use of pesticides, favors air pollution and the acceleration of climate change.


The demand for soy has grown in recent years and that is why soy has become part of the most harmful food for the environment. Their plantations have deforested wonderful green areas of the planet as it happened in the Amazon jungle.



The chicken and pig farms consume a lot of resources to be able to maintain and / or increase their production but the cows come to consume 11 times more water for example.

The faeces and gases emitted by the cattle, specifically the methane from their flatulence, also they are highly polluting and seriously harm the planet. Methane is a flammable gas and is considered a greenhouse gas that contributes to global warming



It is one of the most used foods in the world gastronomy and yet it is one of the most polluting the environment. Their crops have high methane emissions, gas that harms the planet contributing to climate change and, in addition, its extensive extensions of plantations need large amounts of fresh water to develop and grow.

These very healthy vegetables would not say that they are one of the foods that may be contributing to the destruction of the planet but, we are sorry to tell you, they do it, even though it is not their fault. The production of a kilo of asparagus emits 8.9 kilos of CO2, how can that be possible? Simple, by its commercialization to other countries, transferring them by plane, since it is a food that grows mainly in South America and from there it is distributed massively to the US and to some European countries.
