The power of beets!

Beetroot

Beetroot have recently shot to fame in the vegetable department and for good reasoning. This versatile vegetable is delicious raw, cooked or pickled. The colourful leaves can also be cooked and used similar to spinach in dishes. There are so many varieties of beetroot with yellow and red being the most popular.

Aside from the taste, consuming beetroot has multiple benefits. Nitrate is found in all vegetables, however it is particularly abundant in dietary nitrate. Consuming dietary nitrate lowers blood pressure by causing our blood vessels to dilate and relax.1

Studies also show that consuming beetroot in the form of juice may enhance athletic performance2-4. Beetroot juice reduces oxygen use during physical exercise and increases blood flow to exercising muscles therefore increasing exercise tolerance.2-3 Many studies have shown that athletes who consume beetroot juice before athletic events can have faster finishing times than those who dont.3-5 Fortunately, the research also suggests its not just elite athletes who can benefit from the perceived benefits of beetroot, average gym-goers can too. One study compared performance between two average running groups. The first group consumed 200g of cooked beets 75minutes before a race and the second group consumed an alternative food. The group that consumed the beetroot portion ran faster and reported less exhaustion than the placebo group.2


Aside from their vibrant colours and dietary nitrate content, beets contain other beneficial plant compounds. Bentanin is the pigment responsible for that rich colour of beets. Bentanin is also a powerful antioxidant which slows the effects of ageing.6 Beetroot has a low glycemic load, high fiber content (3g/100g serving) and low calorie content (40kcals/100g serving). 

Beetroot and beetroot greens can easily be incorporated into anyones diet. Roasting beets in their skin brings out their sweet flavour. After roasting, simply wrap the cooled beet in a cloth and rub gently to remove the skins. Beet greens are delicious when sautéed in garlic and seasonings. Store-bought diced beets or beetroot juice can also be added to smoothies for a quick snack or colourful breakfast. See attached smoothie recipe for some beet-inspiration.
