Raisins
Raisins are dried grapes. The drying process concentrates both the nutrients and sugars present in grapes, making raisins nutrient-dense and calorie-dense.
Raisins originated in the Middle East before making their way to Europe, where they were especially popular among the Greeks and Romans. Historically, raisins were used as currency, as awards in sporting events, and to treat ailments like food poisoning.
