Purified grains of sand have an anti-obesity effect

Scientists seem to have found a new unusual weight loss remedy: porous silica particles made from

cleaned sand.

The researchers tested various sizes andforms of silica in a model of the human intestine after a heavy meal. The results support the idea that porous silica can "hinder the digestive processes" that are normally triggered by enzymes. Moreover, the size of the administered nanoparticles seems to determine the degree of inhibition of digestive activity.

Thus, the ideal samples of silica were microparticles with a pore width of 6 to 10 nanometers. Now scientists want to test this in animals, and then possibly in humans.
