Salt is an essential ingredient in our daily diet, present in almost every kitchen in the world. However, recent research reveals an invisible threat: microplastics.
These tiny plastic fragments —less than five millimeters— have infiltrated even the most basic ingredient in our food.
The problem is not only environmental, but also a potential risk to human health.
Microplastics: How do they get into the salt?
A study found microplastics in 36 of 39 salt brands tested worldwide, indicating that up to 90% of sea salt could contain them . The highest levels were found in sea salt, followed by lake salt and rock salt ( source ).
But how do these plastic fragments get into the salt?
Microplastics come from everyday products such as synthetic fibers (polyester, nylon, acrylic), urban dust, tires, marine paints, and cosmetics. In particular, 35% of ocean microplastics come from synthetic fibers released during laundry. These particles are so small that wastewater treatment systems cannot filter them out, and they end up in the oceans, where they contaminate the seawater.
Environmental impact and impact on marine life
Microplastics not only pollute the water, but also enter the marine food chain. Studies with zebrafish show that ingesting microplastics causes intestinal inflammation, oxidative stress, liver toxicity, and alterations in lipid and energy metabolism.
This poses a significant risk to food security and aquatic ecosystems.
Microplastics in the human body: a silent risk
The research also indicates that microplastics can cross the intestinal membrane, enter the bloodstream, and accumulate in organs such as the liver and brain. They can even cross the placental barrier, affecting future generations ( source ).
Furthermore, microplastics carry chemical pollutants such as phthalates, bisphenols, and organotins, which are associated with oxidative stress, cellular toxicity, endocrine disruption, and metabolic disorders. Some scientists link this pollution to the global increase in obesity and metabolic diseases in recent decades.
The importance of choosing a salt free of microplastics
In a world where plastic pollution is increasingly difficult to avoid, choosing pure and certified products plays a key role. At Sal Ancestral , our salt comes from an ancient spring located more than 600 meters above sea level, far from human influence and environmental pollutants.
Our independent analyses confirm that our salt is free of microplastics and heavy metals , ensuring not only taste and quality, but also peace of mind for your health.
Daily consumption of microplastics could reach about 5 grams per week , the equivalent of the weight of a credit card.
In Ancestral Salt We believe that the health of the planet and our own health are deeply connected. That's why we are committed to:
-
Ongoing research on microplastics and their impact.
-
Rigorous testing on our products.
-
Promoting the reduction of plastic consumption.
