Nutrition Facts

Per 100g (raw celery)

* % Daily Value based on a 2,000 kcal diet.


Quick summary: Celery contains just 14 calories per 100g and 6 calories per stalk. It is the only dietary source of 3-n-butylphthalide — a compound that clinically reduces blood pressure by 12.5% with daily consumption. Celery is also rich in apigenin, which has anti-anxiety effects by binding GABA receptors similarly to benzodiazepines. With only 1.4g of net carbs per 100g, celery is fully keto-compatible.

Celery is 95% water — the third most hydrating vegetable after cucumber and iceberg lettuce. Net carbs are 1.4g per 100g. The 'negative calorie food' claim is false — celery does have 14 kcal per 100g and digestion does not burn more than that — but celery is genuinely one of the lowest-calorie foods available.

Celery Health Benefits & Nutrition

Blood Pressure — 3-n-Butylphthalide

Celery is the only significant dietary source of 3-n-butylphthalide (3nB) — a phthalide compound that relaxes smooth muscle in blood vessel walls, dilating arteries and reducing blood pressure. A 1992 study at the University of Chicago found that 4 stalks of celery daily for 1 week reduced blood pressure by 12.5% in patients with mild hypertension. Traditional Chinese medicine has used celery for blood pressure for centuries. Research in animals found 3nB was as effective as standard antihypertensive drugs at equal doses.

Apigenin — Anti-Anxiety and Anti-Cancer

Celery is one of the richest sources of apigenin — a flavonoid with notable pharmacological effects. Apigenin binds to GABA receptors in the brain (the same receptors targeted by benzodiazepine drugs), producing anxiolytic (anti-anxiety) effects. It also demonstrates anti-cancer properties across multiple cancer lines in laboratory research, particularly for breast, prostate, and colon cancer. Celery seeds contain the highest apigenin concentration, but celery stalks and leaves also provide meaningful amounts.

Digestive Health and Weight Management

At 14 kcal per 100g with 1.6g of fiber and 95% water content, celery is extremely effective for adding volume to meals without adding calories. The 'crunch factor' of raw celery also slows eating pace, improving satiety signals. Celery's insoluble fiber adds bulk and promotes regular bowel movements. Research shows that starting meals with high-volume, low-calorie foods like celery significantly reduces overall calorie intake at the meal.

Anti-Inflammatory Compounds

Celery contains multiple anti-inflammatory compounds beyond apigenin: luteolin, quercetin, kaempferol, and phthalides. These collectively inhibit COX-2 enzymes (the pathway targeted by ibuprofen) and reduce NF-κB signalling — a key inflammatory pathway. Regular celery consumption is associated with reduced markers of systemic inflammation in population studies. Celery leaves contain higher concentrations of anti-inflammatory compounds than the stalks.

Frequently Asked Questions

How many calories in celery?
Celery contains 14 calories per 100g. One medium stalk (40g) has just 6 calories. A cup of chopped celery (101g) has 14 calories. Use the slider above for any weight.
Is celery a negative calorie food?
No — this is a persistent myth. Celery has 14 kcal per 100g and digestion burns only 0.5-1 kcal per 100g consumed. The body always gains net calories from celery. However, celery is genuinely one of the lowest-calorie foods available and excellent for weight management.
Is celery good for blood pressure?
Yes — celery contains 3-n-butylphthalide (3nB), a compound that relaxes blood vessel walls and lowers blood pressure. A clinical study found 4 stalks daily reduced blood pressure by 12.5% in hypertensive patients. Celery is used in traditional medicine for blood pressure management in multiple cultures.
Is celery keto?
Yes — celery has only 1.4g of net carbs per 100g. One stalk has just 0.7g of net carbs, making it completely compatible with ketogenic diets. Celery with peanut butter or cream cheese is a popular keto snack.
Should I eat celery leaves?
Yes — celery leaves contain higher concentrations of flavonoids (apigenin, quercetin) and vitamin C than the stalks. They have a more intense, slightly bitter flavour suitable for soups, stocks, and salads. Most people discard them, but they are nutritionally superior to the stalks.
Does celery juice have special benefits?
Celery juice has been heavily marketed with exaggerated claims. It provides the same nutrients as whole celery but without the fiber. The anti-inflammatory compounds and 3nB are present in juice, but the lack of fiber reduces the gut health benefits. Eating whole celery is nutritionally preferable to celery juice.
