- KetoYes
Yes — Celery is keto-friendly (3.32 g net carbs per 100g, within the ≤10 g net carbs bar). (may not account for sugar alcohols; per-100g basis is a rougher heuristic than per-serving.)
≤5g net carbs per serving — our bar, not a regulatory standard. How we set this
- Low-CarbYes
Yes — Celery is low-carb (3.32 g net carbs per 100g, within the ≤15 g net carbs bar). (may not account for sugar alcohols.)
≤15g net carbs per serving — our bar, not a regulatory standard. How we set this
- Low-SugarUnclear
We can't determine whether Celery is low in sugar from the available data — worth a quick check against the label before you buy.
≤5g sugar per serving — our own criterion; the FDA defines none. How we set this

No — Celery is not high in protein (0.4921875 g protein per 100g, below the ≥10 g protein bar).
≥10g protein per serving — FDA 21 CFR 101.54 (≥20% DV). How we set this

Read the sourced research
Monash University's lab testing rates 10g of raw celery stalk - about a quarter of a stalk - as low-FODMAP.
Larger portions move into moderate-to-high mannitol territory, while celery leaves are tested separately and stay low-FODMAP up to a much more generous 75g.
Other sources cite a notably larger stalk threshold, but that figure isn't corroborated elsewhere, so this uses the Monash-tested 10g number. [3]Celery allergy affects about 0.45% of European adults overall, per the Paul-Ehrlich-Institut. Prevalence varies sharply by country - up to around 40% of food-allergy patients in Switzerland report celery root allergy.
In people already sensitized to mugwort pollen, testing positive for the Api g 7 protein was linked to about 6 times higher odds of a severe anaphylactic reaction versus just mild oral symptoms. [4]A medium celery stalk (about 40g) has roughly 1g of carbohydrate, per Ketogenic.com's breakdown.
Net carbs - total carbs minus fiber - come in under that gram, making celery an easy fit for keto portions. [5]
Health Benefits
A small trial found 1.34 g/day of ethanolic celery seed extract lowered systolic blood pressure by 11.08 mmHg and diastolic by 6.54 mmHg versus placebo, over 4 weeks in a triple-blind, placebo-controlled design.
Several of that trial's authors were affiliated with a company that sells celery seed extract, a conflict of interest worth keeping in mind, since this result isn't independently confirmed. [1]
Storage & Buying Tips
Commercial cold-chain storage at 0-2°C can keep celery marketable for up to 7 weeks.
That's far longer than typical home refrigeration reaches, so store shelf life and fridge life are two different numbers, not one "celery lasts X" figure. [2]
Frequently Asked Questions
Is it safe to eat celery every single day?
For most healthy adults, yes - there's no established upper daily limit on whole celery in a normal diet.
The caveat is about juice, not stalks: drinking a lot of concentrated celery juice raises your sodium and plant-compound intake noticeably, and can interact with certain medications (see the blood-thinner question below). [6]
Can pregnant women eat raw celery?
Yes - the UK's NHS specifically names celery, alongside carrot and cucumber, as a healthy pregnancy snack.
Wash it well first: unwashed produce can carry soil-borne toxoplasma parasites, which pose a real risk during pregnancy. [7]
What are the allergy symptoms associated with celery?
Most celery reactions are mild - tingling or itching in the mouth and throat - from cross-reactivity with birch or mugwort pollen.
But a genuine celery allergy can go further, causing hives, swelling, or anaphylaxis; in oral-challenge studies, roughly half of celery-allergic patients had whole-body reactions rather than just mouth symptoms.
Celery is one of 14 major allergens that must be labeled by law in the EU and UK. [8]
Does celery interact with blood-thinning medications?
Concentrated celery juice - not whole celery - is the part flagged for caution on blood thinners, mainly for its concentrated sodium and plant-compound load.
Whole celery isn't on Mayo Clinic's specific list of high-vitamin-K foods that warfarin patients are told to eat consistently - that list is mostly leafy greens like kale and spinach.
It still has a moderate 29.3 mcg of vitamin K per 100g, so keeping portions steady day to day is a reasonable precaution anyway. [9]
Why do people say celery has "negative calories"?
It's a popular myth, not something nutrition science actually supports.
An energy-balance study that accounted for the calories burned chewing and digesting celery, plus what's lost as waste, still found a net energy gain - not a loss.
Reviewers agree there's no such thing as a true negative-calorie food, though celery's low calorie count and high water and fiber content can still fit well into a lower-calorie diet. [10]
Why do celery stalks sometimes taste bitter?
Bitterness is almost always a growing-conditions issue, not a safety problem.
Not enough shielding from sunlight before harvest, heat stress, underwatering, or a plant left too long past its roughly 130-140 day maturity window can all concentrate bitter compounds in the stalk.
Modern cultivated celery has actually been bred for centuries to tone down those naturally bitter, aromatic compounds, like butylphthalide and sedanolide.
Individual differences in bitter-taste-receptor sensitivity also affect how strongly any one person notices it. [2]
