Organic food

To avoid or at least reduce the pollutants entering our bodies in our food as much as possible, various measures can be put in place.  

We suggest that, in general, you try and eat the most natural and least processed foods possible. By doing this, you will be able to reduce the amount of hormones, additives, pesticide residues, GM crops etc. which you are exposed to.

You should also favour fresh and seasonal foods and be aware of the levels of meat and animal fats that you consume. Many toxins, which are particularly persistent, build up in fat. The concentrations of this type of pollutants are usually higher further up the food chain, and are therefore lower in vegetables.

There is also a risk that animal feed used on farms may contain hormones or antibiotics which can remain as residues in the animal’s meat. One option to reduce these risks is to opt for meat, eggs, milk and other animal products with ecological certification. Another alternative is to reduce the consumption of animal products, particularly those which contain more fat.

Eating a lot of fruit and vegetables, especially those which have been ecologically certified, means that you will ingest fewer toxins. Fruit and vegetables also provide us with antioxidants which can help us to counteract some of the effects caused by toxins, and are more nutritious than many other foods.

As for fish, due to fears about the excessive presence of mercury in some species, institutions such as the Rovira y Virgili University and the University of Barcelona, have designed tools like the Ribepeix program which set the quantities of each species we can safely consume, according to our personal characteristics, without exceeding the set toxin levels.

With regards to kitchen utensils, packaging, wrappers etc., it is better to avoid some products altogether e.g. cast iron, stainless steel or ceramic coated containers, as well as glass receptacles.

You should also not heat food inside their packaging as, in the case of some plastics, they can emit harmful chemicals.
