Dates are a surprisingly tasty and healthy fruit. Thanks to their useful properties, dates are called “pantry of nature” and in the Arab countries they are still called “bread of the desert”. Dates may be eaten fresh, dried, boiled or fried; they are used to make jams, jellies, stewed fruit and different drinks. Dates are often eaten instead of sweets with tea or milk. It is considered that this fruit is able to supply all nutrients that are necessary for a man.
On average, one date contains 23 calories. Due to the fact that the dates are low-calorie and contain a wealth of nutrients, they are recommended for use lieu of candy for everyone who is dieting or just trying to maintain normal weight. Dates consist of:
