Medjool dates are a popular variety of dates due to their natural sweetness. They can provide various health benefits. However, it is advisable to consume them in moderation.

Date palm trees (Phoenix dactylifera L.) are one of the most ancient cultivated trees in the world. Throughout history, the dates that grow on them have been a staple crop in Southwest Asia and North Africa. Many people refer to medjool dates, which are native to Morocco, as “the king of dates” due to their large size and sweet taste. They are one of the most popular dates in the United States, alongside Deglet Noor dates.

In this article, we will discuss the nutritional information of medjool dates, as well as the potential benefits and risks of eating them.

Medjool dates are a large variety of date that feature a sweet, almost caramel-like taste. They are oval shaped, with a dark brown color and textured skin. Like all dates, medjool dates have a pit in the middle, surrounded by flesh.

While they are native to Morocco, many farmers grow medjool dates in warm regions of the U.S., the Middle East, South Asia, and Africa. As the harvesting of medjool dates occurs early in the ripening season, they are a soft date. People often sell them dried, but not dehydrated, which makes them soft and sticky. Their sugars concentrate as they dry, which further enhances their natural sweetness.

According to the U.S. Department of Agriculture, a single medjool date contains 66.5 calories and provides:

One medjool date also provides many minerals such as:

Medjool dates do not contain much protein or fat. However, they are a great source of energy, most of which comes from sugars. They contain a large amount of fiber. Medjool dates contain also particularly high levels of potassium. In fact, per gram, medjool dates contain roughly twice as much potassium as a banana.

Medjool dates are high in fiber, most of which is insoluble fiber. Unlike soluble fiber, insoluble fiber is indigestible. Since the body does not break down insoluble fiber, this fiber helps moves food and waste through the digestive system quickly and more efficiently, helping prevent constipation.

Both soluble and insoluble fiber help prolong feelings of fullness after eating, which may also help with weight management.

Research shows that consuming adequate quantities of fiber can help lower the risk of diseases such as type 2 diabetes, cardiovascular disease, and colorectal cancer. This is consistent with a 2015 study suggesting that introducing dates into the diet increases bowel movements and decreases ammonia in the stool. These findings support the idea that consuming dates may help prevent colon cancer.

In addition to containing high levels of fiber, medjool dates also contain many antioxidants such as phenolic acids and flavonoids. A 2021 systematic review and meta-analysis highlights that medjool dates are a particularly rich source of phenolic compounds.

Antioxidants may be beneficial to a person’s health as they can prevent or slow down the effects of unstable molecules, known as free radicals, that can cause damage in the body. Free radicals cause oxidative stress that evidence suggests may contribute towards the risk of certain cancers, cardiovascular disease, and inflammatory conditions.

Evidence suggests that the consumption of antioxidants is associated with a lower risk of cardiovascular disease and neurodegenerative diseases. An older study of nine Israeli varieties of dates shows that medjool dates may have potential anti-atherogenic properties. This means that they contain compounds that may prevent atherosclerosis, a condition that results from a narrowing and hardening of arteries.

Medjool dates are also a great source of potassium. Potassium is necessary for many functions that occur in the body, from heart and kidney function to the function of muscles and nerve transmission. People in America only consume around half of their recommended daily amount of potassium.

Low levels of potassium may increase the risk of kidney stones, high blood pressure, strokes, and increase the depletion of calcium in bones.

Since medjool dates are high in fiber, they may be a useful food for weight management. However, medjool dates are high in calories, so consuming them beyond moderate amounts may lead to weight gain. Medjool dates mostly contain carbohydrates, the majority of which are sugars. This may cause people who are trying to regulate their blood sugar, such as those with diabetes, some concern.

Some evidence suggests that dates do not cause spikes in blood sugar and may in fact have a low glycemic index. However, researchers do not yet fully agree upon the exact relationship between dates and blood sugar. Therefore, people who are trying to regulate their blood sugar levels may need to be mindful of dates’ high sugar content when consuming them.

Medjool dates contain large amounts of potassium. While potassium can provide health benefits, consuming too much can cause health problems such as hyperkalemia. People who follow a low potassium diet, such as those with kidney disease and individuals taking medications that affect kidney function, should be mindful of the high potassium content in medjool dates.

Medjool dates are one of the most common dates in the U.S. and people can easily buy them in most grocery stores. Medjool dates have a pit in the middle that people can remove after slicing the date from the top to the bottom.

Due to their sweet, caramel taste, people may consider using them in desserts or sweet dishes. The American Institute of Cancer Research provides dessert recipes containing medjool dates such as a chocolate and date mousse and date, walnut and dark chocolate cookies. People may also incorporate medjool dates into their diet by:

  • adding them to fruit smoothies
  • using them as a topping for oatmeal and cereals
  • mixing them into salads and other savory dishes
  • stuffing them with nuts or cheese

Medjool dates are a good source of energy and are easily available in many grocery stores. Their high sugar content gives them a sweet, caramel flavor that makes them a useful sweetener for many dishes. They are also full of antioxidants that are associated with many health benefits.

However, medjool dates also have a high calorie content, as well as high levels of fiber and potassium. Although these can be healthy elements in a person’s diet, some people may want to consume medjool dates in moderation.
