[HIGHLIGHTS] What is natto, the mucus-like, ammonia-smelling food that has become fashionable for its health benefits?

Natto is a traditional Japanese food made from fermented soybeans. The beans are cooked, a tablespoon of sugar is added to them and then exposed to the action of the bacterium 'bacillus suptiles' for 24 hours at a temperature of 40 degrees.

When fermented, it gives off like a viscous slime with a fairly strong smell, similar to ammonia, and the consistency of a mucus. Despite its undeniable "preventive power", María Amaro warns that "natto is beneficial within the framework of a healthy diet but, in no case, as we are trying to'sell', serves to replace any drug when we need it"
