Dates and raisins often occupy the same mental category: very sweet dried fruit that is easy to snack on. That is accurate, but it hides a surprise. Raisins are not necessarily higher in sugar per 100 g than Medjool dates, even though both taste intensely sweet.
Start with the 100-gram comparison
USDA reference values put Medjools at about 277 calories, 66–67 g of sugars, and 6.7 g of fiber per 100 g. Unsweetened raisins provide roughly 299 calories, 59 g of sugars, and 3.7 g of fiber per 100 g.
| Per 100 g | Medjool dates | Raisins |
|---|---|---|
| Energy | ≈277 kcal | ≈299 kcal |
| Sugars | ≈66–67 g | ≈59 g |
| Fiber | ≈6.7 g | ≈3.7 g |
| Potassium | ≈696 mg | ≈749 mg |
Dates stand out for fiber: 6.7 g versus 3.7 g per 100 g. Raisins provide about 22 more calories per 100 g, while potassium is close—roughly 749 mg in raisins versus 696 mg in Medjools.
These are reference foods, not universal specifications for every package. Date variety, grape variety, moisture, and added coatings can move the numbers. If you are comparing two products in a store, the Nutrition Facts panel on those packages is more useful than assuming every date or raisin matches a database average.
A 30-gram serving makes the gap smaller
Thirty grams of Medjool dates contains about 83 calories, 20 g of sugars, and 2.0 g of fiber. The same 30 g of raisins provides about 90 calories, 18 g of sugars, and 1.1 g of fiber.
A 7-calorie gap is trivial at that serving size. The fiber difference is more noticeable: dates provide about 0.9 g more per 30 g. Neither, however, is as fiber-efficient per calorie as beans or many vegetables.
Thirty grams can also look deceptively small because drying removes most of the water that gave the fresh fruit bulk. That is why a measured portion can fit easily into breakfast or a snack, while grazing from a large bag can turn two or three servings into one without feeling like a huge volume of food.
Piece size changes the way you eat them
One large Medjool weighs about 24 g, so 30 g is only a little more than one date. Thirty grams of raisins is dozens of small pieces. That physical difference matters because a handful can disappear without much counting.
A large date also packs plenty into one piece: about 66 calories and 16 g of sugars. Neither format automatically guarantees portion control. A stuffed date with nut butter or chocolate is also a different snack from a plain date, just as raisins mixed into candy or sweetened cereal are different from plain raisins.
What about minerals?
Both contribute potassium plus smaller amounts of iron, magnesium, and other minerals. Exact numbers shift with variety and processing. For potassium, 30 g of raisins provides roughly 225 mg and 30 g of Medjools about 209 mg—a difference of only about 16 mg.
There is no need to manufacture an overall winner from that. Choose for taste, texture, and how the food fits the meal. If fiber is your main criterion within this pair, dates have the edge; if you prefer raisins, the small calorie or potassium differences are not a compelling reason to switch.
If fullness is part of the goal, what you pair them with matters too. Adding a measured portion to plain yogurt or nuts brings protein or fat into the snack and makes the dried fruit part of a more substantial eating occasion. Eating them alone is fine, but concentrated sweetness can make mindless handfuls easy when no portion is set.
Both are still concentrated fruit
Plain dates and raisins do not need added sugar to reach these numbers. Their naturally occurring fruit sugars become concentrated because most of the water is gone. That makes them different foods from table sugar, but it does not make a large serving low in carbohydrate.
Using them as a visible ingredient can make portions easier to understand: 20–30 g in oatmeal, yogurt, or a nut mix adds sweetness and texture without turning the package into an endless snack. Serving size matters more than a small numerical gap between two dried fruits.
