If you’ve ever seen a sidewalk stained deep purple in early summer, you’ve probably met a mulberry tree. These delicate, fleeting berries are wildly underrated. They look a bit like a lanky blackberry, taste like a sweet-tart grape, and are often ignored in favor of their supermarket cousins. That's a shame. Because fresh, raw mulberries aren't just delicious — they're incredibly low in calories and pack a surprising vitamin C punch. The trick is knowing what to do with them in their very short season.
↑ Fresh mulberries are delicate and best eaten right after picking.
The underrated summer berry
Mulberries are the fruit of the Morus tree, and they come in white, red, and the most common deep-purple-black varieties. Unlike a blackberry, a mulberry doesn't have a solid core; it's more fragile, with a tiny, edible green stem that often comes along for the ride. You won't find them in plastic clamshells at the grocery store. They're too delicate to ship. This is a local, seasonal, 'eat them right off the tree' kind of fruit, which is part of its charm.
IN ONE LINE
A 100g serving of mulberries has just 43 calories but delivers around 40% of your daily vitamin C. They're a low-sugar, nutrient-dense choice.
Mulberry nutrition facts
Here’s the nutritional breakdown for a 100-gram serving of raw mulberries, which is a generous handful or about two-thirds of a cup.
The standout number here is the vitamin C. Getting 40% of your daily value from such a small, low-calorie portion is fantastic. The fiber isn't super high, but at 1.7 grams, it's still a helpful contribution that works with the low sugar content to keep you full and your blood sugar stable.
Mulberry's glycemic index
We don't have an official, lab-tested Glycemic Index (GI) number for mulberries. They're just not a fruit that's been studied in the same way as apples or bananas. But we can make a very educated guess.
Based on their low sugar content, decent fiber, and similarity to other berries like raspberries and cherries (which are very low-GI), it's safe to treat mulberries as a low-glycemic food. They're not going to cause the kind of blood sugar spike you'd get from, say, a slice of white bread or even a pineapple.

How to eat them
First, a warning: they stain. Don't wear a white shirt while picking or eating them. Beyond that, it's simple.
01
Eat them fresh and raw.
This is the best way. Just rinse and eat. The little green stem is edible and you'll barely notice it.
02
Stick to a reasonable portion.
A cup (about 140g) is a great serving size. Because they're so easy to eat, it's possible to overdo it, which can sometimes lead to an upset stomach.
03
Forage safely.
If you're picking them yourself, choose a tree away from a busy, polluted road. Give them a good rinse before eating.
04
Freeze the excess.
Their season is short. If you have a bounty, lay them on a baking sheet to freeze individually, then transfer to a bag. They're perfect for smoothies later.
05
Skip the dried version (mostly).
Dried mulberries are a different beast. They're much higher in concentrated sugar and calories. Treat them like candy, not fruit.

Can you eat mulberries raw?
Yes, absolutely! That's the best way to enjoy them. Just give them a gentle rinse. The small green stem is edible and you won't even notice it.
Are mulberries good for people with diabetes?
Yes, in moderation. They are a low-sugar, low-carb, high-fiber fruit with a low estimated glycemic index, making them a good choice. As always, monitor your own blood sugar and stick to a standard portion size like a cup.

A ripe black mulberry is sweet with a mild tartness, often described as a cross between a grape and a blackberry. They are less tart than blackberries and have a softer texture.
