Cranberry nutritional benefits and functional properties

Cranberries are recognized as a functional fruit due to their high concentration of vitamins, minerals, and bioactive compounds. Originating in North America and used medicinally in Europe since the Middle Ages, the fruit contains vitamins A, C, and E, as well as magnesium, phosphorus, and potassium.

Scientific interest focuses on phenolic compounds, particularly proanthocyanidins, which may prevent bacteria from adhering to urinary tract cells. Additionally, polyphenols such as anthocyanins and flavonoids provide antioxidant and anti-inflammatory properties that support cardiovascular health, immune function, and cellular protection. Research also suggests potential benefits for intestinal microbiota modulation and increased serum antioxidant capacity.
