We speak of a true myth: the aphrodisiac food. Meanwhile, a first question arises: do they really exist, but the food can stimulate the activity under the sheets, so to speak? Natural substances, not the "help" chemicals, pills blue that we all know, at least heard ...? Apparently, yes, and confirm it is not the popular wisdom that for centuries has been attributed to this or that food (often very palatable) irrefutable aphrodisiac able to revive the intimacy of the couple, often mortified by the increasingly widespread "loss of desire." To make out a full blown list of substances that really help eros, absolutely harmless to health, it was a very close study - the most accurate ever made in this area - sponsored by the University of Guelph (Canada) and coordinated by the Italian doctor Massimo Marcone, of the Department of Food Science.
