Strawberries come closer to our keto line than any other fruit we have verified, and they still miss it. At 5.68 g net carbs per 100 g (USDA SR Legacy, FDC #167762), raw strawberries land 0.68 g above the 5 g threshold we treat as a keto green light. On our scale that earns a moderation badge for keto and a clear yes for low-carb. Nothing about that is a rejection — it is a portion problem, and it is the tightest portion problem in our whole library.
Here is why the size of the gap matters more than the badge. You can eat 7 medium strawberries, about 84 g, for roughly 4.77 g net carbs and stay under the line. Eat 8 medium berries, about 96 g, and you are at roughly 5.45 g and over it. There is no other food in our verified set where the difference between a green light and a moderation badge is a single berry. Strawberries sit that close.
They are also, by a wide margin, the lowest-carb fresh berry we have credible USDA data for. Blueberries run 12.09 g net carbs per 100 g (FDC #171711), elderberries 11.4 g (FDC #171727), mulberries 8.1 g (FDC #169913), and frozen loganberries 7.72 g (FDC #169088). A strawberry is roughly half a blueberry's carbohydrate load for the same weight. If you eat fruit on a low-carb pattern and you want the cheapest one per gram of carbohydrate, this is it.
One honesty note before the table: our verified entry is raw strawberries only. We publish no separate figure for frozen, canned in syrup, or strawberry jam, because those are different products with different sugar loads and we will not estimate them. Our no-data policy applies here as it does everywhere else on this site.
The Numbers, per 100 g of raw strawberries
The card above is pulled directly from USDA FoodData Central and is never hand-copied. Three rows deserve a slower look. First, sugar accounts for almost all of the net carbs: 4.89 g out of 5.68 g, which is 86 percent (FDC #167762). Strawberries have a gentle reputation because they taste light, but the carbohydrate they do carry is nearly all sugar rather than starch — fiber strips away only 2.0 g from a 7.68 g total. Second, calories are just 32 kcal per 100 g and the fruit is about 91 percent water (USDA FoodData Central, FDC #167762), which is why a bowl of strawberries looks far more generous than it costs. Third, potassium is 153 mg and magnesium 13 mg per 100 g — modest next to raw spinach at 558 mg potassium for 1.43 g net carbs (FDC #168462), but real if you are tracking electrolytes on a very-low-carb pattern. Our keto flu and electrolytes guide covers the full mineral arithmetic.
The nutrient that actually stands out is not on the badge cards. Strawberries carry 58.8 mg of vitamin C per 100 g — about 65 percent of the US FDA Daily Value of 90 mg (USDA FoodData Central, FDC #167762; US FDA Daily Value). A 152 g cup of halved berries delivers roughly 89 mg, which is essentially a full day's requirement. That is a genuine point in their favor, and it is worth remembering that it comes attached to 8.63 g of net carbs, not zero.
What a Real Portion Costs — the Cup Math
This is where strawberries get decided, because almost nobody weighs them. USDA lists household measures for the same record we use, and the spread between them is large enough to change your answer. The arithmetic below is ours, run on the 5.68 g per 100 g figure from FDC #167762:
- 1 cup whole (144 g) — about 8.18 g net carbs
- 1 cup halves (152 g) — about 8.63 g net carbs
- 1 cup sliced (166 g) — about 9.43 g net carbs
- 1 cup pureed (232 g) — about 13.18 g net carbs
- 1 pint as purchased (357 g) — about 20.28 g net carbs
Two things fall out of that list. The first is that slicing changes the number without changing the fruit: a cup of sliced berries carries 1.25 g more net carbohydrate than a cup of whole ones, purely because slicing removes the air gaps. If you are eyeballing portions, slice them after you decide how many you are eating, not before. The second is the pint. A full pint of strawberries lands just past the 20 g line that separates our low-carb yes from our low-carb no. Nobody eats a pint in one sitting by accident, but the number is worth knowing because it is the point at which strawberries stop being a low-carb food and start being a dessert-sized dose of carbohydrate.
For comparison against the fruit most people are actually asking about: 150 g of strawberries costs about 8.52 g net carbs, while the same 150 g of banana costs about 30.36 g (FDC #173944, 20.24 g per 100 g). That is roughly three and a half times the carbohydrate for the same weight on the plate — which is the entire reason the banana verdict reads differently from this one.
How to Eat Them — and What to Eat Instead
On low-carb, a cup of strawberries fits inside a 100 g daily carbohydrate budget without argument. On keto, treat the fruit as a line item you measure rather than a garnish you scatter. When you want the dessert role filled with something that costs less, these are the verified options, all from our library:
Heavy whipping cream (the classic pairing)
Cream runs 2.84 g net carbs per 100 g (FDC #170859) — half of strawberries, and it brings 2.84 g of protein and 340 kcal per 100 g with it. A 40 ml pour is 1.14 g. This is the pairing that lets a small bowl of berries read as a real dessert, and the recipe below prices both versions.
Sour cream and ricotta (the thicker versions)
Sour cream sits at 4.63 g net carbs per 100 g (FDC #171257). Ricotta is 5.14 g (FDC #171248) but carries 11.39 g protein per 100 g, which is a much better trade if the goal is staying full rather than just staying sweet. Both work as a base under sliced berries when cream alone feels thin.
Pecans and chia (the crunch and the fiber)
Pecans are 4.26 g net carbs per 100 g with 9.6 g fiber (FDC #170182). Chia is a different animal: 7.72 g net carbs per 100 g, but that figure comes after subtracting 34.4 g of fiber from a 42.12 g total (FDC #170554). A realistic 15 g spoonful of chia is about 1.16 g net carbs, and it thickens cream into something closer to a pudding. Raw coconut meat runs 6.23 g net carbs per 100 g with 9.0 g fiber (FDC #170169), and coconut oil is 0 g (FDC #171412) — fat with no carbohydrate attached.
Plain yogurt (not flavored)
Plain whole-milk yogurt is 4.66 g net carbs per 100 g with 3.47 g protein (FDC #171284). The flavored versions are where the carbohydrate hides, and our Greek yogurt breakdown shows the exact size of that gap: plain Greek yogurt at 3.98 g against a flavored cup at 11.55 g per 100 g.
A Keto Recipe: Strawberries and Cream, Priced Two Ways
The same dessert, two builds. One clears the keto line, the other is an honest low-carb portion. Pick by your badge, not by your appetite.
Keto build (one serving, under 5 g net carbs): 60 g strawberries, hulled and halved · 40 ml heavy whipping cream · a pinch of ground cinnamon (optional)
Low-carb build (one serving, under 20 g): 150 g strawberries · 100 ml heavy whipping cream · the same pinch of cinnamon
- Chill the bowl first. Cream whips faster and holds longer when everything is cold, which matters because this dessert has no thickener.
- Whip the cream to soft peaks. Stop before it turns stiff — overwhipped cream separates, and there is no sugar in this build to stabilize it.
- Hull and halve the berries last, immediately before serving. Cut strawberries soften within about twenty minutes and release water that will thin the cream underneath them.
- Fold the berries in gently or spoon them over the top, then dust with cinnamon. Eat it right away.
By the numbers: the keto build runs about 4.55 g net carbs (3.41 g from 60 g of strawberries at FDC #167762, plus 1.14 g from 40 ml of cream at FDC #170859). The low-carb build runs about 11.36 g (8.52 g from 150 g of berries plus 2.84 g from 100 ml of cream). A pinch of cinnamon adds well under 0.2 g either way, since cinnamon's 27.49 g per 100 g (FDC #171320) only matters at spoonful scale, not pinch scale.
Fun Fact: The Berry That Isn't One
In botanical classification, the garden strawberry is not a berry. It is an aggregate accessory fruit — the fleshy red part is the swollen receptacle that held the flower's ovaries, not the ovaries themselves. Each of those little "seeds" on the outside is a separate botanical fruit called an achene, and every one of them is a genuine fruit with a seed inside. A strawberry is dozens of tiny fruits sitting on a stem tip that grew sweet enough to be worth eating.
The strawberry we buy is also a hybrid, and a young one. Fragaria × ananassa was first bred in Brittany, France, in the 1750s by crossing the Virginia strawberry from eastern North America with the Chilean strawberry, which had been carried to Europe from South America. Every supermarket strawberry in the world descends from that cross, which is why the naming includes the × mark — it is the botanical signal for a hybrid. So the fruit that misses our keto threshold by less than a single berry is, taxonomically, both not a berry and not a species.
Are strawberries keto-friendly?
They are the closest fruit to keto-friendly we have verified, but they do not clear our green light. At 5.68 g net carbs per 100 g (USDA SR Legacy, FDC #167762), strawberries sit 0.68 g above the 5 g line and earn a keto moderation badge alongside a low-carb yes. In practice the portion decides it: 7 medium berries (about 84 g) come in at roughly 4.77 g net carbs and clear the line, while 8 medium berries (about 96 g) land near 5.45 g and do not.
How many strawberries can I eat on keto?
Work outward from 5.68 g net carbs per 100 g (FDC #167762). Hitting the 5 g line exactly takes about 88 g of berries — roughly 7 medium strawberries at 12 g each, which comes to about 84 g and 4.77 g net carbs. A measured cup of whole berries is 144 g and about 8.18 g net carbs — fine on low-carb, past the keto green light. If you want a number to remember, make it 100 g: one weighed portion of about 8 medium berries, 5.68 g net carbs, and no arithmetic required at the table.
Are strawberries lower in carbs than blueberries?
Yes, by roughly half. Strawberries are 5.68 g net carbs per 100 g (FDC #167762) against 12.09 g for raw blueberries (FDC #171711). Both have 2.0–2.4 g of fiber per 100 g, so the gap is not a fiber effect — blueberries simply carry more sugar, 9.96 g against 4.89 g per 100 g. On a per-gram-of-carbohydrate basis, strawberries are the better choice of the two, and our blueberry verdict runs the same math on the bowl sizes people actually eat.
