Is celery juice really that magical?

In recent years, many health reports have claimed that celery juice can "cure" a variety of diseases. This should be viewed with caution.

• Insufficient research support:There are currently insufficient human studies to confirm that celery juice can treat any disease. Existing claims are mostly based on personal experience or observation and should not be equated with medical guarantees.
• Fiber loss:Most of the dietary fiber is filtered out during the juicing process, and fiber is one of the important nutritional benefits of celery. If you want to get fiber, it's usually better to eat the whole celery stalk.
• High oxalate levels:Celery juice has a high oxalate content, which may put a strain on people who are prone to kidney stones or have weak kidney function. These individuals should consult a doctor before drinking it.
