Cranberry jelly is the best drink for colds and flu, due to the content of ascorbic and acetylsalicylic acids. The jelly retains all the vitamins of the fruits and berries used in its preparation. It can be used as a substitute for one of the meals, such as afternoon tea. Jelly has an alkalinizing effect on the body, which is very important for people suffering from acidity or gastritis and ulcerative diseases of stomach and duodenum. The jelly is rich in organic acids and its beneficial and therapeutic properties depend on those fruits, of which it is made.
