Celery is a very healthy vegetable, which contains many vitamins and minerals and has many benefits to human body. However, if you eat too much celery or have special circumstances, eating more celery may also have some disadvantages, such as:

Affect renal function: celery contains more oxalic acid. If the intake is excessive, calcium oxalate crystals may be formed, and long-term intake will cause a burden on the kidneys.

Allergy induction: The specific protein contained in celery may cause allergic reaction in some people, which is manifested as itchy and red skin.

Affect the efficacy: the nutrients in celery can promote the absorption of drugs, and if the drugs are taken at the same time, the efficacy may be affected.

Affect blood sugar: celery has a high cellulose content, which can lower blood sugar, but if it is ingested in excess, it may lead to low blood sugar and physical discomfort.
