Crispy, fresh, and incredibly versatile, celery is one of those often overlooked foods in the kitchen, used more as a base for sautés than as a main ingredient. Yet, this boldly flavored vegetable conceals a veritable powerhouse of beneficial substances. Rich in water, fiber, and minerals, celery is highly regarded in the nutritional field for its purifying, diuretic, and anti-inflammatory properties. It's no coincidence that it's often included in detox diets, low-calorie diets, and functional drinks like smoothies. Here are all the benefits of celery and its possible side effects.
Celery's Properties and Benefits
Nutritionally, celery is low in calories but rich in active ingredients. It is over 90% water, making it an excellent natural hydrator. It contains fiber, which aids digestion, and a good amount of minerals such as potassium, calcium, magnesium, and phosphorus. Furthermore, it is an interesting source of vitamin K, vitamin C, some B vitamins, and antioxidant compounds such as flavonoids and polyacetylenes. These properties translate into several health benefits, including:
1. Promotes Diuresis
Thanks to its high water and potassium content, celery stimulates urine production, helping the body eliminate excess fluids and toxins.
2. It Has a Purifying Effect
Its draining properties support the activity of the liver and kidneys, making it ideal during periods of detox or light eating.
3. Aids Digestion
The fibers present in celery help regulate intestinal transit and prevent bloating and constipation.
4. Fights Inflammation
Some antioxidant compounds in celery, such as flavonoids, have an anti-inflammatory effect, useful in countering chronic inflammation or mild joint pain.
5. Helps Control Blood Pressure
The presence of potassium, a mineral that helps balance sodium levels, can help keep blood pressure under control.
6. Supports the Immune System
Vitamins – and in particular vitamin C – and antioxidant compounds help strengthen the body's natural defenses.
7. It Can Promote Weight Loss
Being low in calories and rich in water and fiber, celery is a satiating food with very few calories, ideal for weight loss diets.
Celery's Contraindications
Despite its many benefits, celery is not suitable for everyone: some people may be allergic, especially those with cross-allergies to pollen, carrots, or fennel. In these cases, consumption may cause reactions such as itching, oral swelling, or gastrointestinal problems. Furthermore, celery contains photosensitizing substances (such as furanocoumarins), which in sensitive individuals or if consumed in large quantities, can increase the risk of skin reactions following sun exposure. Those taking anticoagulant medications should consume it in moderation due to its high vitamin K content, which can interfere with blood clotting. Finally, given its diuretic effect, it is important for those with kidney problems or taking diuretics to consult their doctor before regularly incorporating it into their diet.
