Carrots may do more than just improve vision—they might also play a role in managing type 2 diabetes, according to a new study by researchers in Denmark.

The study, published in Clinical and Translational Science in December 2024, highlights the potential health benefits of carrots, particularly their bioactive compounds that appear to aid blood sugar regulation and promote a healthier gut microbiome.

“We see carrots as a potential component of future dietary strategies for type 2 diabetes,” said Lars Porskjær Christensen, a professor of analytical chemistry at South Denmark University, in a news release.

Study Insights

Using a mouse model, researchers conducted a 16-week experiment to explore the metabolic effects of carrots. Mice induced with type 2 diabetes were fed a high-fat diet to mimic an unhealthy lifestyle. They were then divided into two groups: one received a diet supplemented with 10% freeze-dried carrot powder, while the other did not.

The results were promising. Mice consuming the carrot-supplemented diet showed improved blood sugar regulation, as measured by glucose tolerance tests. Researchers attribute this improvement to the bioactive compounds in carrots, which enhance the cells’ ability to absorb sugar.

In addition, the carrot-enriched diet positively influenced the gut microbiome, shifting its composition toward a healthier balance. “Our study showed that adding carrots to the diet altered the composition of the gut microbiome,” said Christensen. The gut microbiome, a diverse community of microorganisms in the digestive tract, plays a crucial role in overall health and metabolic function.

Implications for Humans

While the study focused on mice, the researchers are optimistic about the potential for similar benefits in humans. They aim to secure funding for further research to confirm these findings in people and explore whether carrots could enhance existing diabetes treatments.

If successful, the findings could have significant implications for the millions of people living with type 2 diabetes in the United States.

Best Ways to Consume Carrots

The researchers suggest minimal preparation of carrots to retain their health-promoting properties. Cooking may reduce the concentration of beneficial compounds, but they are not entirely lost. Eating carrots raw or lightly cooked is recommended for maximum benefits.

Though further studies are needed, this research provides another reason to include carrots in a balanced diet, especially for those managing or at risk of type 2 diabetes.
