Vitis vinifera (Common grape) has been present and part of our diets since the Neolithic period, being harvested since thousands of years ago both, for medicinal and nutritional value . Raisins are dried grapes that may be eaten either raw, as part of after meal snacks or even used in elaborated culinary dishes and menus.

Raisins have also the same medicinal and nutritional values of Vitis vinifera (Common grape), while keeping a sweeter flavor and higher contents of fiber. Indeed, raisins have both types of fibre, viscous and insoluble fibers . As you may already know viscous fibers are good because they delay gastric emptying of ingested foods into the small intestine, giving you the sensation of fullness, reducing blood glucose concentration, potentially benefiting insuling sensitivity [2,4] and improving cholesterol levels , and insoluble fibers, which are poorly absorbed by our body, characteristic that makes them ideal to improve fecal bulk and ameliorate constipation, playing a very important role to increase our total dietary fiber intake .
If that wasn't enough, now, the results of a research presented at the American Diabetes Association’s 72nd Annual Scientific Session suggests eating raisins three times a day may significantly lower postprandial (post-meal) glucose levels when compared to common alternative snacks of equal caloric value .
