Dates share a history with some of the world's earliest civilizations. People have been enjoying them for so long -- well over 5,000 years -- that no-one remembers the history of how we first came to enjoy this delectable fruit. One thing is for sure: People consume dates not only for their flavor but also for their nutritional value.

The date palm (Phoenix dactylifera) is mainly found in northern Africa and the Arabian Peninsula, where it has played a large role in the economy of the region. Currently, the largest producers of dates are countries in those regions, with the exception of the United States.

The date fruit, the plant's most famous feature, grows in clumps at the base of the branches, with each clump weighing up to 20 pounds. The fruit is oval upon harvest and appears either bright yellow or bright red. There is a seed pit within each fruit that also contains a lot of vitamins and minerals.

In production, the fruit is ripened in five stages, with each stage having a specific flavor profile. When it ripens, the sugar content increases, while the protein content decreases. There are three varieties of dates: Hard, soft, and semi-dry – its most common form.

In terms of nutrients, the date fruit has 70 percent digestible sugar. This includes glucose, fructose, and sucrose. It's also a good source of fiber, and it has a small amount of fat and protein. All nine essential amino acids are found in date pits, and the fruit holds 23 amino acids in total. It also is an excellent source of minerals, including iron, calcium, magnesium, potassium, manganese, phosphorus, and zinc, as well as trace amounts of sulfur, cobalt, copper, fluorine, boron, and selenium.

The date pit, in particular, has fiber and a number of fatty acids. These include lauric, myristic, palmitic, and stearic acids. The monounsaturated fatty acids found in dates are palmitoleic and oleic acids, and ?-linolenic and linoleic acids are polyunsaturated fatty acids present in date pits. According to research, oleic acid can reduce low-density lipoprotein (LDL) cholesterol in the body while ?-linolenic acid can boost overall cardiovascular health. Head-to-head, pressed oil from date pits contains more tocopherols than olive oil and higher antioxidant content than coconut oil, depending on the origin.

The date fruits are also a great source of polyphenolic compounds, such as lignans, carotenoids, and flavonoids, including anthocyanins and procyanidins. Studies show that most of the health benefits of the date fruit are linked to its polyphenol content, which improves overall health. In particular, carotenoids and flavonoids found in both the fruit and seed have a high antioxidant activity that guards the body against free radical damage which can cause disease. Procyanidins, bioactive ingredients with powerful antioxidant properties, are found in date fruits, depending on their ripeness.

That's not all: Compounds known as beta-glucans, found in the date fruit and palm pollen, exhibit antitumor activity, as well as boost immune defense and other natural cell protection activity. This, in turn, inhibits the growth of tumor cells. Studies have also shown that beta-glucans can reduce high cholesterol and blood pressure levels in patients with diabetes.
