Beetroot, a vibrant root vegetable, is being recognized by health experts for its significant nutritional value and potential health benefits. Packed with essential vitamins, minerals, and nitrates, the vegetable is praised for its contributions to vascular health, exercise performance, and even libido. Its vivid color also signals the presence of anti-inflammatory antioxidants.
Nutritional Content
A standard 80-gram serving of beetroot, equivalent to about three small whole baby beetroots or seven slices of larger beetroot, provides a substantial amount of key nutrients. This serving size delivers 44% of the NHS's recommended daily intake of folate (vitamin B9). It also contains 13% of the daily target for manganese, crucial for bone and joint health. Lesser, but still significant, amounts of Vitamin C, potassium, magnesium, and iron are also present, all vital for cardiovascular health.
Beetroot is also noted for being low in calories, with approximately 34 per 80-gram serving, and relatively high in fiber. However, it is also quite high in carbohydrates, with natural sugars accounting for a significant portion.
Cardiovascular Benefits
The nitrates found in beetroot are a key component of its health benefits. These nitrates are converted into nitric oxide in the body, a compound that helps to relax and widen blood vessels. This vasodilation allows blood to flow more easily, potentially leading to lower blood pressure. Multiple scientific studies have indicated a link between beetroot juice consumption and reduced blood pressure, particularly impacting systolic blood pressure.
Workplace wellness nutritionist Lily Soutter notes that while most studies on exercise performance and blood pressure have focused on daily beetroot juice consumption, whole beetroot can be a valuable addition to the diet a few times per week for general health and to boost fiber, folate, and potassium intake.
Libido and Digestion
Beetroot's ability to improve blood flow through vasodilation has led to hypotheses about its potential to boost sex drive, as good vascular health is important for erectile function. However, the evidence supporting this claim is limited, with most positive research concentrating on the benefits of nitrates for blood pressure and exercise performance.
For digestion, beetroot offers gut-friendly fiber. Certain compounds within beetroot, such as pectin, can act as prebiotics, fueling beneficial gut bacteria. As these bacteria ferment prebiotics, they produce short-chain fatty acids that support the gut lining's health. Nevertheless, beetroot contains FODMAPs, which can cause digestive issues like bloating and gas in individuals with sensitive guts or irritable bowel syndrome.
Antioxidant Properties
The distinctive red and purple pigments in beetroot, known as betalains, are the subject of scientific interest for their antioxidant and anti-inflammatory properties. These phytonutrients help protect cells against damage from free radicals, which are unstable molecules implicated in aging and chronic disease development. While betalains are thought to support overall health and potentially protect against chronic disease, further research is needed to fully understand their long-term effects.
Considerations and Interactions
Individuals taking medications for high blood pressure, heart failure, or kidney disease should exercise caution with beetroot consumption, especially in large amounts or concentrated supplements. The nitrates can cause a significant drop in blood pressure, potentially leading to dizziness or dangerously low blood pressure episodes. Those already managing low blood pressure should also avoid concentrated beetroot supplements.
People with chronic kidney disease, particularly stages 3 to 5, need to be mindful of beetroot's potassium content, which could contribute to harmful electrolyte imbalances. Additionally, due to its oxalate content, beetroot may pose issues for individuals prone to calcium oxalate kidney stones.
When consuming pickled beetroots, it is advisable to be aware of added salt and sugar. For those seeking gut health benefits, fermented beetroot products are recommended as they contain live bacteria.
