This article contains findings obtained from research on animals:
- The results from animal research studies should not be directly applied to humans and the results may not generalise to the human population.
- There may be significant differences between species in terms of physiology, physiology, and pharmacology, as well as differences in the way diseases and treatments are modelled in animals.
- Any conclusions drawn from animal research should be considered with caution and in the context of other types of research studies such as observational studies, clinical trials, and reviews of the literature.
Insights & Discussion
Carotenoid-rich foods like orange carrots were more effective in mitigating Non-alcoholic fatty liver disease than those with low carotenoid levels.
In this study, male C57BL/6J mice were randomly assigned to one of four experimental diets for a period of 15 weeks: a low-fat diet, a high-fat diet, a high-fat diet with 20% white carrot powders, or a high-fat diet with 20% orange carrot powders.
Observations revealed that those mice on the high-fat diet enriched with carotenoids from the orange carrots gained less weight and displayed less hepatic lipid deposition compared to the white carrot group. Moreover, lower levels of triglyceride content were seen in the orange carrot group. The increase of particular proteins indicated that carotenoids found in orange carrots improved β-oxidation, thereby inhibiting NAFLD development more significantly. Further examination showed noticeably higher mRNA and protein levels of a particular transcription factor.

Pomegranate peel extract, along with a calorie deficit diet, could improve risk factors of metabolic syndrome and reduce fatty liver in patients with non-alcoholic fatty liver disease.
2023 Nutrition Journal Pomegranate (Punica granatum L.) peel extract ameliorates metabolic syndrome risk factors in patients with non-alcoholic fatty liver disease: a randomized double-blind clinical trial Barghchi H, Milkarizi N, Belyani S, Norouzian Ostad A, Askari VR, Rajabzadeh F, et al.
Randomised Controlled Trial NAFLD
In the first phase, the research involved the hydro-alcoholic extraction of the peel of 750 kilograms of pomegranate using the soaking method. The second phase saw patients with non-alcoholic fatty liver disease divided into two groups - a placebo group and a pomegranate peel capsule group. Both groups followed a diet with a 500 kcal deficit for eight weeks. Aspects like intolerance to the treatment, participants' dietary intake, their lipid and glycemic profiles, blood pressure, body composition, insulin resistance indexes and changes in fatty liver disease evaluated through elastography were monitored.
Further, the study reported substantial decreases in multiple indicators such as body weight, waist circumference, body mass index, body fat index, trunk fat, blood pressure, total cholesterol, triglyceride levels, LDL cholesterol, fat free mass, and fasting blood sugar in the group that took pomegranate peel capsules compared to the placebo group. Meanwhile, HDL cholesterol and liver steatosis and stiffness saw improvement. No significant differences, however, were found in the insulin and homeostatic model assessment for insulin resistance between the two groups.
Consuming carrots can significantly decrease the risk of cancer.

Meta-Analysis Cancer Carrot
The methodology used in this research involved examining the links between carrot intake and the incidence of cancer. The scope was broad, examining all studies published before June 2022 that offered risk estimates connecting cancer incidence with either carrot consumption, α-carotene intake, or α-carotene plasma levels. Possible sources of such studies included those found via digital searches, manually identified within other studies, or garnered from existing reviews. Analysis was carried out comparing the highest and lowest reported intakes from prospective studies, estimating summary relative risks using a random-effects model.
The study's results indicated a strong correlation between carrot consumption and a notable reduction in cancer risk. This conclusion was derived from the analysis of 198 observational studies, 50 of which were prospective studies involving a total of 52,000 cases that specifically recorded carrot intake. Comparatively, on the correlation between α-carotene plasma levels and cancer risk, analysis from 30 prospective studies with 9,331 cases indicated that a higher presence of α-carotene also resulted in decreased cancer risk. Despite a moderate variance between studies, these findings serve as significant evidence in support of the anticancer benefits of carrots.
Phytochemicals in carrots, particularly carotenoids, are effective at reducing eyesight degeneration and treating chronic eye defects due to their antioxidant and anti-inflammatory properties.

Throughout the review process, seventy original research and review articles were examined, all published between 2000 and 2020 across four major journal databases: Elsevier, PubMed, ResearchGate and Plos One. The focus of the search was directed by six keywords, centring on both in-vivo and in-vitro study results related to the topic of interest.
Among the various findings, it was consistently revealed that carrots contain a multitude of bioactive compounds, notably carotenoids, which have been proven to be effective in halting and treating eye degenerations including Nyctalopia, Myopia, Cataracts, Age-related Macular Diseases and Glaucoma. Carotenoids have been found to work as potent antioxidants and anti-inflammatory agents, defending eyes against vision loss due to oxidative stress. Thus, the increased consumption of carrots can potentially serve as a natural therapeutic approach and enhancer of vision.
Regular consumption of raw carrots, specifically 2-4 or more per week, is associated with a decreased risk of colorectal cancer.
2020 Nutrients Carrot Intake and Risk of Colorectal Cancer: A Prospective Cohort Study of 57,053 Danes Deding U, Baatrup G, Christensen LP, Kobaek-Larsen M
Cohort Study Carrot
The methodology of the study involved examining the risk of being diagnosed with colorectal cancer in correlation with carrot intake in a Danish population of 57,053 individuals over a lengthy follow-up period. Self-reported intake of raw carrots was recorded, setting a baseline of 2-4 or more carrots each week as the metric for study.
Results derived from this study show that individuals who consumed 2-4 or more raw carrots per week showed a decrease in the risk of colorectal cancer, as compared to individuals with no intake of the same. However, an intake of less than 2-4 carrots per week did not show a significant association with reduced colorectal cancer risk. Therefore, this supports the notion from previous studies that stated consumption of carrots could have a preventive effect against colorectal cancer.
Sleep quality in adults with disturbed sleep improved significantly after an 8-week course of naturally-derived sleep-inducing juice made from lettuce, orange, pineapple and cherry.

Randomised Controlled Trial Heart Rate Variability Lettuce Orange
This randomized, crossover study involved 25 adults (15 female, 10 male), all of whom reported difficulties in initiating or maintaining nighttime sleep. During the intervention, known as the feeding sessions (FS), the participants were given a sleep-inducing juice made of natural ingredients, being provided 250ml twice a day for 8 weeks. Their sleep quality and other related parameters were tracked with wearable actigraphs over seven consecutive days. The Pittsburgh sleep quality index (PSQI) scores were assessed before and after this juice intervention. The subjects' heart rate variability (HRV), both at rest and during sleep, was also closely monitored.
After the participants had undergone the 8-week juice intervention (FS), the PSQI scores decreased substantially, a change which directly correlated with a significant decrease in fatigue severity scale and visual analogue scale levels. Notably, heart rate variability indices indicative of vagal activity were significantly improved during the FS. The sleep efficiency and the total sleep time of the subjects increased significantly; at the same time, sleep latency and other disruptive factors like total counts, sleep fragmentation index, and movement index decreased significantly. There weren’t any significant differences observed during the non-feeding sessions (N-FS). Overall, the study results showed that the targeted intake of the sleep-inducing juice improved not only the sleep quality, but also led to an enhanced cardiac vagal tone during sleep.
