Celery has quietly become one of those foods surrounded by big promises. From weight-loss claims to social media wellness trends, it's easy to believe that one simple vegetable could hold the secret to better health. But when researchers examine the evidence, the picture looks much less dramatic.
According to the Norwegian science publication forskning.no , nutrition researcher Astrid Kolderup Hervik from the University of South-Eastern Norway has reviewed what science actually says about celery.
Her conclusion is clear: celery is a healthy vegetable, but many of the claims made about it go far beyond the available evidence.
The myths don't match the science
One of the most common claims is that celery contains "negative calories," meaning the body burns more energy digesting it than it gains from eating it. Current research does not support that idea.

Celery is low in calories and rich in water, fibre, potassium and folate, making it a nutritious addition to a balanced diet. Its high water and fibre content can also help people feel fuller for longer, which may support healthy weight management.
Is celery juice worth the hype?
Drinking celery juice every morning has become a popular wellness habit, but there is little scientific evidence showing it offers unique health benefits.
According to Hervik, much of the research often cited focuses on concentrated plant extracts rather than celery consumed as part of a normal diet.
For most people, eating whole celery is the better choice because it retains the fibre that is largely removed during juicing, helping promote fullness and supporting digestive health.

A balanced diet matters most
The researchers' overall message is straightforward. No single food can determine a person's health on its own, and celery is no exception.
While it is certainly a healthy vegetable, the strongest evidence continues to support eating a varied diet rich in different fruits, vegetables and whole foods rather than relying on one trending ingredient.
