Beetroot, scientifically known as Beta vulgaris rubra, is a root vegetable celebrated for its earthy flavor, vibrant color, and impressive nutritional profile. From ancient Mediterranean civilizations to modern-day athletes, beetroot has been cultivated and consumed for its culinary and medicinal properties. This article delves into the numerous health benefits of including beetroot in your diet, supported by scientific evidence and practical tips for incorporating this versatile vegetable into your meals.
A Colorful History and Nutritional Powerhouse
Beetroot, also known as red beet, table beet, or garden beet, boasts a rich history and diverse range of varieties. From the classic vibrant red to golden and even candy-cane striped hybrids, all colors of beetroot share a distinctive earthy taste and offer a visual appeal to any dish. Both the leaves and roots of beets are packed with essential nutrients, including antioxidants that combat cell damage and reduce the risk of chronic diseases.
Nutritional Profile of Beetroot
Beetroot is low in calories and fat while being a rich source of essential vitamins, minerals, and beneficial plant compounds. A 3.5-ounce (100-gram) serving of boiled beetroot provides:
- Calories: 44
- Protein: 1.7 grams
- Fat: 0.2 grams
- Carbs: 10 grams
- Fiber: 2 grams
- Folate: 20% of the Daily Value (DV)
- Manganese: 14% of the DV
- Copper: 8% of the DV
- Potassium: 7% of the DV
- Magnesium: 6% of the DV
- Vitamin C: 4% of the DV
- Vitamin B6: 4% of the DV
- Iron: 4% of the DV
Beets are particularly high in folate, a B vitamin crucial for cell growth, development, and cardiovascular health. They also provide a good amount of manganese, essential for bone formation, nutrient metabolism, and brain function, as well as copper, an important mineral for energy production and neurotransmitter synthesis.
Key Health Benefits of Beetroot
1. Boosting Stamina and Exercise Performance
Beetroot and its juice have been shown to enhance the efficiency of the heart and lungs during physical activity. This is attributed to the nitrates present in beets, which are converted into nitric oxide in the body. Nitric oxide improves blood flow to the muscles, allowing them to work more efficiently and for longer periods.

Several studies suggest that dietary nitrates, like those found in beets, may improve athletic performance. Nitrates appear to affect physical performance by improving the efficiency of mitochondria, which are responsible for producing energy in your cells. According to one review, beetroot juice could enhance endurance by increasing how long it takes to become exhausted, boosting cardiorespiratory performance, and improving efficiency for athletes.
Consuming beets or beetroot juice a couple of hours before exercise can help maximize these benefits.
2. Supporting Cardiovascular Health and Lowering Blood Pressure
Beets are naturally high in nitrates, which the body converts into nitric oxide. This compound helps relax and widen blood vessels, leading to lower blood pressure. Studies have demonstrated that beetroot juice can significantly reduce both systolic and diastolic blood pressure.
Beets are also a great source of folate. Although research has turned up mixed results, several studies suggest that increasing your intake of folate could significantly lower blood pressure levels.
Furthermore, beets contain betaine, an antioxidant that has also been linked to cardiovascular benefits.

3. Enhancing Immune Function
Beets are a good source of fiber, which promotes the growth of beneficial bacteria in the gut. A healthy gut microbiome is essential for a strong immune system, as it helps fight off disease-causing pathogens. Fiber also aids in digestion and prevents constipation.
4. Promoting Skin Health
Research indicates that beetroot juice may improve inflammation and blood flow, both of which are vital for maintaining healthy skin. The antioxidants in beets can also protect skin cells from damage caused by free radicals.
5. Providing Antioxidant and Anti-Inflammatory Protection
Beetroot is one of the few vegetables that contain betalains, powerful antioxidants that give beets their vibrant color. Betalains have been shown to reduce inflammation and may help protect against cancer and other diseases. Beets also contain other helpful plant compounds that contribute to their antioxidant and anti-inflammatory properties.
These anti-inflammatory effects could benefit several aspects of health, as chronic inflammation has been associated with conditions like obesity, heart disease, liver disease, and cancer.
6. Supporting Digestive Health
Beetroot is a good source of fiber, which is essential for maintaining a healthy digestive system. Fiber adds bulk to stools, promoting regularity and preventing constipation. It also feeds beneficial gut bacteria, contributing to a healthy gut microbiome.

7. Potentially Improving Brain Function
The nitrates in beets may improve brain function by increasing blood flow to the brain. Studies have shown that beetroot consumption can enhance blood flow to the frontal lobe, an area associated with decision-making and working memory.
8. Exhibiting Anti-Cancer Properties
Beetroot contains several compounds with cancer-fighting properties, including betaine, ferulic acid, rutin, kaempferol, and caffeic acid. Research suggests that beetroot extract can slow the growth and division of cancer cells.
9. Aiding in Weight Management
Beets are low in calories and high in water and fiber, making them a valuable addition to a weight-management plan. The fiber content promotes feelings of fullness, which can help reduce overall calorie intake.
