The Benefits and Side Effects of Celery

Celery is not just a crunchy snack; it may also offer several health benefits, particularly concerning blood pressure management. However, like any food, it carries potential side effects that should not be overlooked.

Health Benefits of Celery

Research suggests that celery might help reduce high blood pressure. Despite its relatively high sodium content—approximately 100 mg in one cup of chopped celery—this vegetable contains compounds that may promote relaxation of the smooth muscles lining blood vessels. One such compound is NBP, which is primarily responsible for celery's unique taste and aroma.

Clinical Evidence

There have been promising studies regarding celery's antihypertensive effects. For example, a randomized, triple-blind, placebo-controlled clinical trial found that after four weeks of taking celery seed extract, participants experienced a significant drop in both systolic and diastolic blood pressure, with reductions of at least 10 and 8 points, respectively. However, achieving these levels through diet alone would require impractical amounts of celery seed.

Celery Seed and Sexual Function

Interestingly, a study explored the effects of celery seed on women's sexual dysfunction. In this double-blind, randomized, placebo-controlled trial, subjects consuming about 500 mg of celery seed (roughly ¼ teaspoon per capsule, taken three times a day) reported significant improvements in sexual functioning after just three weeks.

Potential Risks and Side Effects

While celery and celery seeds are generally considered safe, they can pose risks for certain individuals:

Thyroid Activity: Excessive consumption of celery leaves or extract has been linked to overactive thyroid gland activity, leading to weight loss through potentially harmful means.
Allergic Reactions: Celery can trigger allergies, particularly in individuals sensitive to certain pollens. In rare cases, it can cause severe reactions, such as anaphylactic shock.
Sun Sensitivity: Compounds called psoralens found in celery can increase sensitivity to sunlight, leading to skin reactions. This is particularly concerning for those who consume large amounts or handle the plant without proper skin protection.

Conclusion

Celery can be a healthy addition to your diet with potential benefits for blood pressure and sexual function. However, it is essential to be aware of its side effects, especially for individuals with specific allergies or thyroid conditions. Moderation and awareness are key to enjoying the benefits of celery while minimizing risks.
