Brief overview of Beetroot
Beetroot is known for its vibrant color, which adds a beautiful touch to various dishes. But did you know that the color of beetroot is not just aesthetically pleasing, but also significant from a nutritional standpoint? The rich red color of beetroot is due to the presence of an antioxidant compound called betanin. This compound not only gives beetroot its appealing hue, but it also offers numerous health benefits.
When it comes to nutritional composition, beetroot is a true powerhouse. It is packed with vitamins, minerals, and antioxidants that contribute to its impressive health properties. Beetroot is a good source of vitamin C, which supports the immune system and promotes collagen production for healthy skin. It also contains essential minerals like potassium, which helps maintain healthy blood pressure levels, and folate, which is vital for cell growth and development.
Beetroot (Beta vulgaris L.) having a place to the Chenopodiaceae family, is high in dietary fibers, minerals (manganese, magnesium, potassium, sodium, phosphorus, iron, zinc, copper, boron, silica and selenium), B complex-vitamins (B1, B2, B3, B5, B6, folate, B12) and also have 50% of phenolic compounds, including betalains, carotenoids, phenols as well as complex carbohydrates, and inorganic nitrate [10, 11].(Saber 2023)
One of the standout features of beetroot is its high antioxidant content. Antioxidants play a crucial role in protecting the body against oxidative stress, which is linked to various chronic diseases. The antioxidants found in beetroot, including betanin, help fend off harmful free radicals and reduce inflammation in the body. This can contribute to a lower risk of conditions such as heart disease, certain types of cancer, and age-related macular degeneration.
this vegetable has effective antioxidant activity via different bioactive compounds such as triterpenes, sesquiterpenoids, carotenoids, coumarins, flavonoids (tiliroside, astragalin, rhamnocitrin, rhamnetin, kaempferol), phenolic compound, glycine betaines, beta-cyanlins, saponins, and betalains [10, 12]. Betalains are water-soluble nitrogenous pigments that exist in most plants of the order Caryophyllales, and red beetroot is the rich source of this pigments [13] due to the presence of betalains composed of red pigments (betacyanins) and yellow pigments (betaxanthins) [6, 14].

Beetroot: A Nutritional Powerhouse
Whether roasted, juiced, or incorporated into your favorite recipes, beetroot is a versatile and nutritious addition to your diet. Not only does it provide a burst of flavor, but it also boasts an impressive nutritional profile that makes it a true nutritional powerhouse.
So, let’s get started and uncover the secrets behind this mighty root vegetable.
1. Rich in Essential Nutrients
Vitamin C is one of the key vitamins found in beetroot. It acts as an antioxidant and helps support a healthy immune system. Potassium is another important mineral boasted by beetroot, which plays a vital role in maintaining proper heart function and regulating blood pressure. Folate, also known as vitamin B9, is abundant in beetroot and is essential for cell growth and the formation of red blood cells.
Beetroot is also known for its high antioxidant content. One particularly notable antioxidant found in beetroot is betanin. This pigment gives beetroot its vibrant red color and contributes to its many health benefits. Antioxidants like betanin help protect the body’s cells from damage caused by harmful molecules called free radicals.
2. Heart-Healthy Properties
Beetroot has gained attention for its potential to improve cardiovascular health and blood pressure. Studies have shown that regular consumption of beetroot may contribute to lower blood pressure levels, which is beneficial for maintaining heart health. The dietary nitrates present in beetroot are believed to play a role in these cardiovascular benefits.
Nitrates are naturally occurring compounds found in various foods, including beetroot. When consumed, these nitrates are converted into nitric oxide in the body, which helps relax and widen blood vessels. This, in turn, may promote better blood flow and lower blood pressure. By improving blood circulation, the dietary nitrates present in beetroot may support overall cardiovascular well-being and reduce the risk of heart-related issues.
3. Beetroot Juice for Endurance
Consuming beetroot juice before physical activity has been shown to have potential benefits for athletes and fitness enthusiasts alike.
One of the key advantages of beetroot juice is its ability to improve oxygen utilization during exercise. Beetroot contains high levels of nitrates, which are converted into nitric oxide in the body. Nitric oxide helps to widen blood vessels, improving blood flow and oxygen delivery to working muscles.
By increasing oxygen availability, beetroot juice may enhance endurance and delay the onset of fatigue during prolonged exercise. This can lead to improved performance and the ability to sustain higher-intensity efforts for longer durations.
The nitrates present in beetroot juice may also have a positive impact on exercise efficiency. Nitric oxide helps to improve the efficiency of the mitochondria, the powerhouses of the cells responsible for energy production. This can result in improved energy utilization and a reduced oxygen cost during exercise.
Nitric oxide has long been recognized for vasculoprotective effects (24), effects on mitochondrial respiration (25), and effects on fatigue development (26). In addition to the biosynthesis of endogenous nitric oxide (24), exogenous dietary sources of NO3− (e.g., green leafy vegetables and beetroot) can markedly increase the bioavailability of nitric oxide (1,27–29). (Senefeld 2020)
It’s important to note that individual responses to beetroot juice may vary, and there is no one-size-fits-all approach. Factors such as genetics, training status, and overall diet can influence the effects of beetroot juice on exercise performance and endurance.
Betanin and its Benefits
Betanin is responsible for the vibrant color of beetroot and plays a crucial role in its health and nutrition benefits. Understanding the chemical composition and structure of betanin can provide valuable insights into its significance in promoting overall well-being.
Sources of Betanin
- Beetroots: Beetroots are the most abundant source of betanin. They are commonly consumed raw, cooked, or juiced and can be incorporated into various dishes, salads, and smoothies.
- Swiss Chard: Swiss chard, particularly the variety with red stems, contains betanin in its leaves and stalks. It can be eaten raw in salads or cooked as a nutritious side dish.
- Rhubarb: Rhubarb stalks also contain betanin, contributing to their vibrant red color. Rhubarb is commonly used in desserts, jams, and sauces.
- Prickly Pear Cactus: Certain varieties of prickly pear cactus produce fruits with a red-purple hue due to the presence of betanin. These fruits can be eaten raw or used to make juices and jams.
- Spinach: While spinach is not as rich in betanin as beetroots, it still contains small amounts of this pigment, particularly in its red-veined varieties.
Betanin belongs to a group of compounds called betalains, which are natural pigments found in various fruits and vegetables. The chemical structure of betanin consists of a nitrogen-containing molecule called betaine, combined with a glucose molecule. This unique composition gives betanin its distinctive red color.
Betanin (BT; betanidin 5-O-β-glucoside;) belongs to the betalain family and is known to play an antioxidant role with excellent electron donor functions of phenolic and cyclic amine groups [25]. In addition, BT exerts various physiological activities such as antioxidant, antihypertensive, anti-inflammatory, anticancer, and antidiabetic activities [26]. Furthermore, a lipid-lowering effect has been confirmed in the aqueous extract of beetroot [27]. (Lee 2023)
Research has shown that betanin is a powful anti-oxident, and exhibits potential anti-inflammatory effects, which can help to reduce inflammation in the body and mitigate the risk of related health conditions. Additionally, emerging studies suggest that betanin may have anticancer properties, with preliminary findings indicating its ability to inhibit the growth of cancer cells.
By exploring the science behind betanin, we gain a deeper understanding of its diverse health benefits and its role in promoting overall well-being. The knowledge gained can aid in optimizing the consumption of beetroot and harnessing the full potential of betanin for improved health and nutrition.
1. Betanin as an Anti-Oxidant
Betanin possesses powerful antioxidant properties that have been linked to various health benefits. Antioxidants help protect the body against harmful free radicals and oxidative stress, which can contribute to chronic diseases and aging.
The antioxidant activity of purified betanin was examined using the DPPH assay, the direct ONOO− reaction, ONOO−-dependent DNA damage, and the lipid peroxidation reaction, and the results showed that betanin possessed higher antioxidant capacity than general antioxidants such as ascorbic acid and quercetin. Furthermore, betanin showed indirect and direct cytoprotective effects against H2O2 and ONOO− cytotoxicity, respectively. The isolation of highly purified betanin in this study will enable more detailed studies on its physiological functions in the future and may potentially contribute to elucidating the food functions of betanin, betanin-containing red beets, and other similar foods.

2. Potential Anti-Inflammatory Effects
Research on Betanin’s Anti-Inflammatory Properties
Scientific studies have investigated the potential anti-inflammatory effects of betanin, the red pigment found in beetroot. These studies have sought to understand the mechanisms by which betanin may reduce inflammation in the body and its implications for overall health and well-being. Inflammation is a natural immune response that helps the body fight off infections and repair damaged tissue. However, chronic inflammation can lead to various health conditions, including cardiovascular diseases, diabetes, and certain types of cancer.
Researchers have found that betanin has the ability to modulate inflammatory pathways, potentially contributing to its anti-inflammatory effects. It has been shown to inhibit the production of pro-inflammatory molecules, such as cytokines, and exert antioxidant activity. By reducing inflammation, betanin may help alleviate symptoms associated with inflammatory conditions and promote overall health.
Betanin induced the transcription of antioxidant genes through Nrf2 and, simultaneously, suppressed the pro-inflammatory NFĸ-B pathways, thus alleviating endothelial damage and atherogenesis [267]. In a rat model, betanin (25 and 100 mg/(kg*day)) attenuated paraquat-induced lung injury, apparently via antioxidant and anti-inflammatory mechanisms [267]. Betalain (100 mg/kg) reduced also carrageenan-induced recruitment of leukocytes, vascular permeability in the peritoneal cavity, superoxide anion generation by leukocytes, levels of tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-1β in the peritoneal fluid and elevated the level of IL-10. These results suggest that betalain can be considered in the treatment of inflammation-associated diseases [268,269,270]. (Sardowska-Bartocz 2021)
The potential of betanin in reducing inflammation holds significant promise for various health conditions. Preliminary research suggests that betanin may be beneficial in managing chronic inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel disease, and asthma. By targeting the underlying inflammatory processes, betanin may help alleviate symptoms and improve the quality of life for individuals affected by these conditions.
Furthermore, betanin’s anti-inflammatory properties may have implications for overall well-being. Inflammation has been associated with the development of chronic diseases, including cardiovascular diseases, neurodegenerative disorders, and certain types of cancer. By reducing inflammation, betanin may help lower the risk of these diseases and promote better health outcomes.
The potential anti-inflammatory effects of betanin make it an exciting area of research, with further studies needed to fully understand its mechanisms of action and potential therapeutic applications. By unraveling the role of betanin in inflammation, researchers can unlock new strategies for managing inflammatory conditions and improving overall health and well-being.
3. Anticancer Properties
Explore emerging studies suggesting betanin’s anticancer effects.
In recent years, emerging studies have shed light on the potential anticancer properties of betanin, the red pigment found in beetroot. These studies have sparked interest in the scientific community and raised awareness of the potential applications of betanin in cancer prevention.
Researchers have been investigating the mechanisms by which betanin may exert its anticancer effects. One potential mechanism is betanin’s ability to act as an antioxidant, neutralizing harmful free radicals that can damage DNA and promote cancer development. Additionally, betanin may exhibit anti-inflammatory properties, which can play a role in suppressing tumor growth.
Furthermore, betanin has been shown to inhibit the proliferation of cancer cells and induce apoptosis, or programmed cell death, in various types of cancer, including breast, colon, liver, and prostate cancer cells.
Pure betanin also strongly inhibited the growth of melanoma cells [217]. In another study, a beetroot extract rich in betanin/isobetanin was found to be cytotoxic to human breast cancer cells, with IC50 values of 25 µM for B16F10 and MCF-7 cells, 35 µM for MDA-MB-231 and human endothelial cells, and no significant effects on human colorectal cells and fibroblasts after 48-h treatment. Treatment with the extract activated both intrinsic and extrinsic pathways of apoptosis in breast cancer cells [211]. Other authors found betanin to be cytotoxic against various cancer cell lines (MCF-7, HCT-116, AGS and NCI-H460) with IC50 values in the range of 142–164 μg/mL [218]. The cytotoxic action of betanin (IC50 of 40 μM) on human chronic myeloid leukemia cell line (K562) involved such cellular events such as release of cytochrome c from mitochondria into the cytosol, cleavage of poly (ADP-ribose) polymerase (PARP), downregulation of Bcl-2 and diminution of mitochondrial membrane potential [214]. In human lung cancer cell lines betanin induced activation of initiator caspase-9, effector caspases-3 and 7, and cleavage of PARP, a target protein of caspase-3 [219]. (Sardowska-Bartocz 2021)
These promising findings have significant implications for cancer prevention. If further research confirms the anticancer properties of betanin, it could pave the way for the development of novel preventive strategies and potential therapeutic options for cancer patients.
Overall, the emerging studies exploring the anticancer properties of betanin highlight the potential of this natural compound in the field of cancer prevention. Further research is needed to fully understand its mechanisms of action and its potential applications in clinical settings. However, these findings provide exciting prospects for harnessing the power of betanin to combat cancer.
Epigenetic Insights and Future Directions
Epigenetics refers to the study of changes in gene expression that occur without changes to the underlying DNA sequence. These changes can be influenced by various factors, including environmental factors, lifestyle choices, and diet.
Epigenetic modifications can have significant implications for overall well-being. They can influence the way our genes are expressed and can impact various aspects of health, including metabolism, inflammation, and disease risk.
A fascinating area of research is exploring the potential epigenetic effects of betanin and beetroot. Preliminary research suggests that certain compounds found in beetroot, such as betanin, may have epigenetic effects, meaning they can modulate gene expression and potentially influence health outcomes.
Paluszczak et al. [22] assessed the role of betanin on the activity and expression of DNMTs in the epithelial breast cancer MCF7 cell line, as well as its effect on DNA and histone H3 methylation. The DNMT activity was inhibited by betanin but did not influence the methylation pattern or the expression of RASSF1A, GSTP1 or HIN-1. (Omari 2021)
These findings suggest that betanin may have the potential to modulate DNA methylation patterns by interfering with the enzymatic activity of DNMTs. Nevertheless this inhibition did not lead to significant changes in DNA methylation patterns or the expression of specific genes implicated in cancer. This research provides insights into the potential epigenetic effects of betanin in cancer cells and highlight the need for further research to elucidate its mechanisms of action and therapeutic potential.
