Small study links carrot juice to changes in colon polyp tissue
A Danish team studied carrot juice in people with advanced colon polyps, which can have a higher risk of developing into colorectal cancer.
Fifteen of 20 participants drank 100 mL of juice each day for 21 days, while five made no dietary change.
The amount of juice was equivalent to about 125 grams of raw carrots.
After three weeks, tissue showed changes in signals linked to cancer and inflammation, including pathways involved in tumour growth.
These were changes in gene activity, not proof that the polyps shrank or that cancer risk fell.
The small, short study does not show that carrot juice prevents or treats cancer.
Researchers say larger controlled studies should check whether the changes lead to real clinical benefits, such as fewer or smaller polyps.
Until then, the findings do not replace recommended screening or a balanced diet.
A small study found changes in cancer- and inflammation-related gene pathways in colon adenoma tissue after participants drank carrot juice daily for 21 days.
The study included 20 people with advanced colorectal adenomas, a precancerous condition, and 15 drank 100 millilitres of juice each day.
The researchers observed lower activity in several pathways linked to cancer development, including WNT, PI3K-AKT and MAPK.
The findings do not show that carrot juice prevents or treats colorectal cancer, or that it reduces adenoma size or recurrence.
The researchers said larger studies are needed to test whether the molecular changes lead to clinical benefits.
- Who
- A Danish research team studied 20 people with advanced colorectal adenomas.
- What
- The study found changes in cancer- and inflammation-related gene pathways after carrot juice consumption.
- When
- Participants drank the juice daily for 21 days. The study was published online on September 15.
- Where
- The study was conducted by researchers at the University of Southern Denmark and Odense University Hospital.
- Why
- The researchers examined whether carrot juice consumption was associated with changes in adenoma tissue.
This story does not have two clearly opposing sides.
Fifteen participants drank 100 millilitres of carrot juice daily, while five received no dietary intervention.
The study was published online in Nutrition and Cancer.
Korean news outlets reported on the study's findings.

What people are saying
Carrot juice is a practical and easy-to-standardize way to provide bioactive compounds derived from carrots.
Follow-up studies should examine not only changes in gene expression and signaling pathways, but also clinical outcomes such as adenoma size, histological progression and recurrence rates.
