A recent study has discovered that consuming a snack of baby carrots just three times a week can significantly elevate skin carotenoid levels in young adults. This effect is even more pronounced when combined with a multivitamin that contains beta carotene. Carotenoids are the compounds responsible for the red, orange, and yellow hues in many fruits and vegetables. When measured in the skin, they indicate the quantity of fruits and vegetables a person has consumed.
Elevated skin carotenoid levels are associated with enhanced antioxidant protection and a reduced risk of chronic illnesses, such as heart disease and certain cancers. Additionally, this marker reflects improved skin health and immune function. “Previous studies have demonstrated that skin carotenoid levels can be increased by consuming three times the recommended serving of fruits and vegetables every day for three weeks,” stated Mary Harper Simmons, a Master of Science in Nutrition student at Samford University.
“Our findings suggest that a small, simple dietary modification—incorporating baby carrots as a snack—can significantly increase skin carotenoid accumulation,” Simmons elaborated. She presented these findings at the annual meeting of the American Society for Nutrition, held from June 29 to July 2 in Chicago.
In the study, researchers randomly assigned 60 young adults to one of several groups: a control group receiving Granny Smith apple slices, a group receiving 100 grams of baby carrots (approximately 1/2 cup), a group receiving a multivitamin supplement containing beta carotene, and a group receiving a combination of baby carrots and the supplement.
The participants’ skin carotenoid levels were measured both before and after the four-week intervention using a noninvasive, research-grade spectroscopy instrument known as the VeggieMeter. The results indicated a significant increase in skin carotenoid levels by 10.8% in the group consuming baby carrots and by 21.6% in the group consuming both baby carrots and the supplement. In contrast, the skin carotenoid levels remained unchanged in the control group and in the group receiving only the multivitamin supplement.
“We found that the combination of baby carrots and a multivitamin supplement containing beta carotene can have an interactive effect on skin carotenoid accumulation,” said Simmons. “To achieve a beneficial effect, people should choose a multivitamin that includes beta carotene and remember to eat baby carrots at least three times a week.”
The study also highlighted that carotenoid accumulation was not increased by multivitamin supplementation alone, suggesting differences in how carotenoids are absorbed from food compared to supplements. This finding underscores the importance of dietary sources of nutrients over supplements alone.
Moving forward, the researchers aim to explore the mechanisms behind these findings and examine the effects of other carotenoid-rich foods, such as sweet potatoes and green leafy vegetables. Although the current findings are promising, the team noted that they should be considered preliminary until they are published in a peer-reviewed journal.
This study sheds light on the potential health benefits of a simple dietary change. By integrating baby carrots into their diet, individuals can significantly boost their skin carotenoid levels, thereby enhancing their antioxidant defenses and potentially reducing the risk of chronic diseases. Moreover, the research underscores the importance of consuming whole foods over relying solely on supplements for nutrient intake.
As Simmons and her team continue their research, they hope to uncover more about the relationship between diet and skin health. Their work promises to contribute to our understanding of how simple dietary choices can have profound effects on overall health and well-being. For now, adding a handful of baby carrots to your weekly snack routine seems like a small but impactful step towards better health.
