Beetroot, a humble root vegetable frequently bypassed in supermarket aisles, is emerging as a nutritional powerhouse that deserves a regular spot in your weekly shopping basket. While the adage "an apple a day keeps the doctor away" is well-known, nutritionists are now championing beetroot for its dense array of vitamins, minerals, and bioactive compounds that can significantly enhance overall health.
The Nutritional Profile of Beetroot
Beetroot is rich in essential micronutrients and dietary compounds that contribute to better bodily function and well-being. Dr Richard Allison, a clinical dietitian and nutritionist at Herbalife, elaborates on the key components:
- Dietary Fibre: Promotes optimal gut health, an area where many Brits fall short of the recommended 30 grams daily intake for adults.
- Inorganic Nitrates: Converted into nitric oxide in the body, these help relax blood vessels, potentially lowering blood pressure, improving cerebral blood flow, and supporting long-term cardiovascular health.
- Betalains: The pigments responsible for beetroot's vibrant colour act as potent antioxidants, reducing oxidative stress and inflammation, thereby lowering the risk of certain chronic conditions.
- Folate (Vitamin B9): Crucial for DNA synthesis, red blood cell formation, and consequently, heart health.
- Manganese: An essential trace mineral vital for metabolism, bone health, and cellular protection.
- Potassium: An important electrolyte for maintaining fluid balance.
- Vitamin C: An antioxidant that bolsters immune function.
- Iron and Magnesium: Aid in oxygen transport, support nerve and muscle function, and help prevent fatigue.
Weight Management and Gut Health Benefits
Beetroot, like many vegetables, is advantageous for weight management due to its low calorie density. Consuming 100 grams of boiled beetroot provides approximately 2 grams of filling fibre with only around 45 calories, compared to snacks like crisps, which can exceed 500 calories per 100 grams.
The vegetable's distinctive purple hue aligns with fermentation expert Dr Johnny Drain's golden rule for gut health: consume a colourful array of plant-based foods, or "eat your CAP." He advises, "Basically, eat anything within the rainbow, and also include brown, black, and white foods. Green items like leaves and red foods such as red cabbage and berries are important, but this extends to items like coffee and cocoa, which contain significant prebiotic ingredients that feed gut microbes, aiding digestion and boosting the immune system."
Beetroot and Sports Performance
Research indicates that beetroot offers substantial benefits for both professional athletes and recreational exercisers. A 2025 systematic review concluded that proper beetroot juice supplementation enhances muscular strength in professional athletes and improves aerobic endurance in non-athletes. Additionally, it can boost lactate tolerance in healthy adults.
Dr Allison, who has served as head of performance nutrition for top-level sports teams, notes, "Beetroot is particularly popular among runners, cyclists, and team-sport athletes. Studies demonstrate it can accelerate recovery, improve endurance by optimising oxygen use in muscles, and enhance high-intensity performance in intermittent sports like football and rugby. It also provides cardiovascular support by mitigating exercise-induced blood pressure spikes and contributing to overall blood pressure reduction."
For those interested in these advantages, he recommends consuming up to 250 millilitres of beetroot juice two to three hours before exercise, as juice delivers more concentrated nitrates.
How to Incorporate Beetroot into Your Diet
Dr Allison suggests, "For everyday health, eating one or two medium beets a few times a week is sufficient." Consuming beetroot in juice form is the quickest method to elevate nitrate levels, which is beneficial around exercise sessions. Eating it raw or grated in salads helps preserve more nutrients. He cautions, "Try to avoid over-boiled or pickled beets, as these processes can diminish their beneficial compounds."
While some research has linked beetroot juice to reduced blood pressure, larger-scale studies are necessary to solidify these findings. Nonetheless, the evidence underscores beetroot's role as a versatile and nutrient-dense addition to a balanced diet, offering a simple yet effective way to support heart health, reduce inflammation, and boost overall vitality.
