Celery (Apium graveolens), especially its stalks, is one of the most underestimated vegetables in daily nutrition. With a crunchy texture and a slightly salty taste, celery stalks are ideal for healthy snacks or detox juices. Rich in fiber, water, antioxidants, and anti-inflammatory compounds, celery can support digestive, cardiovascular, renal health, and more. Additionally, it is a vegetable with very few calories but with significant nutritional impact. In this article, you will discover scientifically proven benefits, ways to consume it, contraindications, and a detailed nutritional table.
Benefits of Celery Stalks
1. Supports Natural Detoxification of the Body
Celery is composed of over 95% water, making it an excellent natural diuretic. Consuming raw stalks or in juice form stimulates the kidneys, helping to eliminate excess sodium and toxins. At the same time, the potassium content supports the body’s electrolyte balance. This combination promotes the reduction of water retention and supports the excretory function of the urinary system. In the long term, a diet that includes celery stalks can reduce the incidence of urinary infections and kidney stones.
2. Reduces Chronic Inflammation in the Body
Celery stalks contain flavonoids such as apigenin and luteolin, known for their anti-inflammatory action. These compounds have the ability to reduce levels of pro-inflammatory cytokines (such as TNF-α and IL-6), which play an important role in autoimmune diseases, arthritis, and chronic inflammation. Regular consumption can help reduce painful symptoms associated with these conditions. Additionally, luteolin has neuroprotective potential, contributing to the protection of the brain against degenerative processes. Through these mechanisms, celery can be a valuable food in preventing inflammatory diseases.
3. Supports Digestion and Relieves Constipation
Celery is an excellent source of insoluble fiber, which adds bulk to stool and accelerates intestinal transit. Fiber helps regulate the intestinal microbiome, supporting the development of beneficial bacteria. Daily consumption of raw stalks can reduce the risk of chronic constipation, bloating, and abdominal discomfort. Furthermore, celery contains compounds with mild carminative effects, reducing the formation of intestinal gas. For those with slow digestion, a snack of celery stalks can aid digestion without adding many calories.
4. Supports Cardiovascular Health
Celery contains phthalides, particularly 3-n-butylphthalide (3nB), a compound that studies show can lower blood pressure by relaxing the smooth muscles in the walls of blood vessels. Additionally, the intake of fiber and antioxidants contributes to lowering LDL cholesterol (the “bad” cholesterol). Through these mechanisms, regular consumption can support the optimal functioning of the cardiovascular system. Systolic and diastolic blood pressure can be favorably influenced in just a few weeks of consistent consumption. Moreover, the potassium in celery helps balance blood pressure through its vasodilatory effect.
5. Contributes to Weight Loss
With only 14 kcal per 100g, celery stalks are among the most diet-friendly foods for weight loss. Consuming them provides satiety due to their fiber content without increasing caloric intake. Additionally, the digestion of celery requires more energy than the food itself provides, a phenomenon often referred to as a negative thermal effect. This does not mean that celery directly burns fat, but it supports metabolism and reduces appetite. It is ideal as a snack between meals and in combinations with hummus, guacamole, or natural peanut butter.
Relevant Studies
Study: 3nB, the Hypotensive Compound in Celery Journal of Medicinal Food
This study isolated the compound 3-n-butylphthalide (3nB) from celery and demonstrated its effect on blood pressure in hypertensive patients. Researchers administered celery extract to subjects for 6 weeks and observed an average reduction of 12-14 mmHg in systolic blood pressure. The effect was comparable to that of some antihypertensive medications but without significant adverse reactions. Additionally, LDL cholesterol levels were reduced by approximately 7%, and triglyceride levels decreased. The proposed mechanism was the relaxation of smooth muscle and dilation of blood vessels. The authors conclude that 3nB has therapeutic potential for treating mild to moderate hypertension. The study is one of the most cited in the field of cardiovascular phytotherapy. The synergistic effect with other compounds in celery, such as potassium, enhances its efficacy. However, the authors emphasize that concentrated doses generated these results, not occasional consumption of stalks.

Contraindications
- Pregnancy: In large quantities, celery extract may have uterotonic effects. Normal consumption of stalks poses no risks, but concentrated juices or supplements should be avoided.
- Allergies: Some individuals may have allergic reactions to celery, including severe reactions (anaphylaxis).
- Severe Kidney Problems: Due to its diuretic effect, individuals with renal insufficiency should consult a doctor before regular consumption.
- Drug Interactions: It may interfere with diuretics, anticoagulants, or antihypertensives, potentially enhancing their effects.
- Photosensitization: Celery contains psoralens, which can increase sensitivity to sunlight if consumed in very large quantities (especially in concentrated juices).
