Are Blackberries High In Carbohydrates

Blackberries are not high in carbohydrates when you look at their overall nutritional profile.
 
In fact, a full cup of fresh blackberries contains only about 14 grams of total carbs, and nearly 8 of those grams come from fiber.
 
That means the net carbs in blackberries sit closer to 6 or 7 grams per cup, which is quite low for a fruit.
 
So if you’ve been wondering whether blackberries are high in carbohydrates, the short answer is no.
 
They’re actually one of the better fruit choices for anyone watching their carb intake.
 
In this post, we’ll break down the carb count in blackberries, compare them to other fruits, and explain why their fiber content matters so much.
 

Why Blackberries Are Not High in Carbohydrates

Blackberries are not high in carbohydrates, and there are several reasons why they earn that reputation as a low-carb fruit.
 

1. They’re Mostly Water

Roughly 85 to 88 percent of a blackberry’s weight is water.
 
That means the actual carbohydrate content gets diluted significantly compared to denser fruits like bananas or mangoes.
 
When you eat a handful of blackberries, you’re mostly hydrating your body, not loading up on sugar.
 
That high water content is one big reason blackberries are not high in carbohydrates.
 

2. Fiber Makes Up a Huge Portion of Their Carbs

Here’s where blackberries really shine.
 
Of the roughly 14 grams of total carbs in a cup, about 7.6 grams are dietary fiber.
 
Fiber is a carbohydrate, yes, but your body doesn’t digest it the way it digests sugar or starch.
 
It passes through your digestive system largely intact, feeding your gut bacteria instead of spiking your blood sugar.
 
That’s why nutritionists often talk about net carbs, which is total carbs minus fiber.
 
And when you do that math for blackberries, you’re left with only around 6 grams of net carbs per cup.
 
That’s remarkably low, especially for something as sweet and satisfying as a berry.
 

3. Their Natural Sugars Are Minimal

Blackberries do contain some natural sugar, but the amounts are modest.
 
A cup has only about 7 grams of sugar, which is far less than what you’d find in an apple, a pear, or a cup of grapes.
 
This low sugar content is another reason blackberries aren’t high in carbohydrates.
 
Even though they taste sweet, that sweetness comes packaged with fiber and water, which slows down how quickly your body absorbs the sugar.
 
The result is a gentle, steady energy release rather than a sharp spike.
 

4. They Have a Low Glycemic Index

The glycemic index measures how quickly a food raises your blood sugar.
 
Blackberries have a very low glycemic index, usually estimated around 25.
 
Anything under 55 is considered low, so blackberries are firmly in the safe zone for people managing blood sugar.
 
This ties directly back to their fiber and water content, which blunt the impact of their natural sugars.
 
So when someone asks if blackberries are high in carbohydrates, the glycemic response tells you they behave much more like a low-carb food than a high-carb one.
 

How Blackberries Compare to Other Fruits

To really understand why blackberries are not high in carbohydrates, it helps to see how they stack up against other popular fruits.
 

1. Blackberries vs. Bananas

A medium banana packs around 27 grams of total carbs with only 3 grams of fiber.
 
That’s nearly double the carbs of a cup of blackberries, and with far less fiber to soften the blow.
 
Blackberries win this comparison easily when it comes to carb-friendly eating.
 

2. Blackberries vs. Apples

A medium apple has about 25 grams of total carbs and roughly 4.5 grams of fiber.
 
Again, blackberries come out ahead with fewer total carbs and more fiber per serving.
 
If you’re counting carbs, blackberries are the smarter pick between the two.
 

3. Blackberries vs. Strawberries and Raspberries

This is a closer race because strawberries and raspberries are also low-carb berries.
 
Strawberries have about 11 grams of total carbs per cup, while raspberries have around 15.
 
Blackberries land right in that same low-carb neighborhood, which is why all three are staples on low-carb and keto-friendly food lists.
 
So while blackberries are not high in carbohydrates, they’re in good company among their berry cousins.
 

Are Blackberries High in Carbohydrates on a Keto or Low-Carb Diet?

Blackberries are not high in carbohydrates, which makes them a great fit for keto and low-carb diets.
 

1. They Fit Within Daily Carb Limits

Most low-carb diets recommend keeping net carbs between 20 and 50 grams per day.
 
With only about 6 net carbs per cup, blackberries leave plenty of room for other nutritious foods.
 
You can enjoy a generous handful without blowing your budget for the day.
 

2. They Satisfy Sweet Cravings Naturally

One of the hardest parts of cutting carbs is missing something sweet.
 
Blackberries deliver that sweet-tart flavor without the carb load of candy or baked goods.
 
Toss a few into Greek yogurt, blend them into a smoothie, or eat them straight from the carton.
 
That natural sweetness is exactly why so many people on low-carb plans reach for blackberries again and again.
 

3. They Add Fiber, Which Low-Carb Diets Often Lack

Fiber can be tricky to get enough of when you cut back on grains and legumes.
 
Blackberries help fill that gap with nearly 8 grams of fiber per cup.
 
That fiber supports digestion, keeps you full, and helps regulate blood sugar.
 
So not only are blackberries not high in carbohydrates, they actively help balance a low-carb eating plan.
 

So, Are Blackberries High in Carbohydrates?

Blackberries are not high in carbohydrates.
 
With about 14 grams of total carbs per cup and only 6 or 7 net carbs after subtracting fiber, they’re one of the lowest-carb fruits you can eat.
 
Their high water content, impressive fiber, low sugar, and low glycemic index all work together to keep their carb impact gentle.
 
Whether you’re on keto, watching your blood sugar, or simply trying to eat smarter, blackberries are a fruit you can enjoy without guilt.
 
So go ahead and add a handful to your next snack or meal, because blackberries are not high in carbohydrates.
