You're standing in the kitchen, staring at a bowl of bright red, juicy berries. They look incredible. But if you're tracking macros or managing blood sugar, that nagging question hits: how many carbs in 1 cup of strawberries? It’s a simple question with a slightly nuanced answer depending on how you slice them—literally.
Most people just want a number.
Basically, a single cup of whole strawberries contains about 11 to 12 grams of total carbohydrates. If you’re a fan of the "net carb" math (total carbs minus fiber), you’re looking at roughly 8 to 9 grams. That is remarkably low for a fruit that tastes like candy. Compared to a banana, which can easily pack 27 grams of carbs, strawberries are basically a cheat code for anyone watching their sugar intake.
But wait.
The weight matters more than the "cup" measurement. A cup of whole berries has a lot of "air" in the gaps. If you slice them thin or mash them up, you’re fitting more fruit into that same measuring cup. Sliced strawberries usually jump up to about 13 grams of carbs per cup. It’s a small difference, but if you’re being precise for keto or insulin dosing, it’s worth noting.
The Breakdown of What’s Actually Inside That Cup
Let's look at the chemistry. Strawberries aren't just sugar water. According to the USDA FoodData Central database, 100 grams of raw strawberries—which is about two-thirds of a cup—provides roughly 7.68 grams of carbohydrates. When you scale that up to a full cup (approx 144g to 150g), you get those 11-12 grams we talked about.
Where do those carbs come from? It’s a mix. You’ve got glucose, fructose, and sucrose.
Interestingly, strawberries have a very low glycemic index (GI). Usually, it hovers around 40 or 41. That’s low. Because of the fiber—about 3 grams per cup—the sugar doesn't just hit your bloodstream like a freight train. It’s more like a slow, steady bike ride. This is why strawberries are often the "safe" fruit recommended by dietitians for people with Type 2 diabetes.

Why the Fiber Matters More Than You Think
Fiber is the hero here.
Most of the fiber in strawberries is manganese-rich and insoluble, but they also contain pectin, which is a soluble fiber. Pectin is the stuff that makes jam thicken. In your gut, it slows down digestion. Honestly, this is the reason you don't feel a massive sugar crash after eating a handful of berries.
I’ve seen people get terrified of the "sugar" in fruit. Let’s be real: the sugar in a strawberry is packaged with water, polyphenols, and vitamin C. Your body treats it very differently than the high-fructose corn syrup in a soda. You're getting a massive hit of antioxidants like anthocyanins—the pigments that make them red—which have been linked in studies to improved heart health and better insulin sensitivity.
Strawberries vs. The Rest of the Berry Patch
If you’re comparing, strawberries are actually lower in carbs than blueberries. Blueberries are great, don't get me wrong, but they're sugar bombs by comparison, hitting nearly 21 grams of carbs per cup.
- Raspberries: About 15 grams of carbs (but a whopping 8g of fiber!).
- Blackberries: About 14 grams of carbs.
- Strawberries: The winner for lowest total carb count at ~12g.
It's kind of wild that the fruit that feels the most like a treat is actually the lightest on the scale.
The "Hidden" Carbs in Modified Strawberries
We have to talk about the trap. Raw strawberries are great. But the moment you move into processed territory, the "how many carbs in 1 cup of strawberries" answer changes drastically.
Ever bought those frozen strawberries in the tub? Check the label. If they are "packed in syrup," you aren't eating 12 grams of carbs anymore. You're likely eating 50 grams or more. Even "unsweetened" frozen berries can be slightly higher in carb density because they’re often picked at peak ripeness (higher sugar content) and packed tightly, removing the air gaps found in fresh whole berries.

And dried strawberries? Forget about it.
When you remove the water, you concentrate the sugar. A cup of dried strawberries is a carb landmine. You’re looking at over 60 grams of carbs because you’ve basically turned them into fruit leather.
Practical Tips for the Low-Carb Life
If you’re trying to stay in ketosis or just keep your energy stable, how you eat these matters. Eating them "naked" is fine. But if you pair them with a fat or a protein, you blunt the glycemic response even further.
Think:
- Sliced strawberries on top of full-fat Greek yogurt.
- Dipped in a bit of heavy whipped cream (no sugar added).
- Tossed in a spinach salad with walnuts and goat cheese.
The fat in the cheese or cream slows down the gastric emptying. Basically, the carbs take even longer to enter your system. It’s a win-win. Plus, it tastes better.
What Science Says About Your Heart and These Berries
There’s some cool research out of Oklahoma State University led by Dr. Arpita Basu. Her studies have shown that consuming about two and a half servings of strawberries a day (which is roughly 2.5 cups) can significantly improve insulin resistance and LDL cholesterol levels in adults with metabolic syndrome.
It sounds counterintuitive. "Eat more carbs to help your insulin?"

Yes, because strawberries aren't just "carbs." They are delivery vehicles for bioactive compounds. The phytosterols and ellagic acid in the fruit actually help fight inflammation. If you’re worried about the 12 grams of carbs, you’re missing the forest for the trees. The metabolic benefits far outweigh the minor carb hit for the vast majority of people.
Common Misconceptions About Strawberry Carbs
One thing that drives me crazy is the "fruit is bad" narrative in some extreme low-carb circles. Some people will tell you to avoid strawberries because they contain fructose.
Here is the reality.
The amount of fructose in a cup of strawberries is roughly 3 to 4 grams. To get the "toxic" levels of fructose that people worry about regarding fatty liver disease, you’d have to eat buckets of strawberries every single day. Your liver can handle a cup of berries while you sleep. Honestly, the stress of worrying about 4 grams of fruit sugar is probably worse for your health than the sugar itself.
Another myth: "Small berries have fewer carbs than big ones."
Not really. While a giant "hollow" strawberry might have slightly less density than a small, tight wild strawberry, the difference is negligible. Weigh your food if you’re obsessed, but otherwise, a cup is a cup.
Actionable Steps for Your Next Grocery Trip
- Buy Organic if possible: Strawberries consistently top the "Dirty Dozen" list for pesticide residue because they don't have a thick skin. If you're eating them for health, you don't want the extra chemicals.
- Check the stems: Look for bright green, fresh-looking caps. If the cap is wilted or brown, the berry is aging, and the sugars are starting to ferment, which changes the flavor and nutrient profile.
- Don't wash them until you eat them: Strawberries are like little sponges. If you wash them and put them back in the fridge, they’ll soak up water, get mushy, and mold faster.
- Use a scale for accuracy: If you are strictly keto (under 20g of carbs a day), stop using a measuring cup. 150 grams of strawberries is the standard "cup" equivalent for 12g of carbs.
- Freeze your own: Buy them fresh when they’re on sale in June, wash them, pat them dry, and freeze them in a single layer on a cookie sheet before bagging them. This keeps the carb count honest compared to store-bought frozen versions that might have additives.
Strawberries are one of the few foods that feel like a literal gift for people watching their weight. They're high volume, low calorie, and low carb. You can eat a whole cup and feel like you actually had a snack, unlike eating three almonds and wondering where your life went wrong. Enjoy the berries.
