The Multifaceted Health Benefits of Beetroot Juice: Historical and Modern Insights

Beetroot has a rich history of use in traditional medicine, dating back to Roman times when it was considered beneficial for cooling the blood. This belief was rooted in the observation that beetroot seemed to alleviate feverish conditions, particularly in growing children. Over time, further benefits of beetroot were discovered, including its strong regulatory effect on the digestive system.

Historical Perspectives and the Doctrine of Signatures

The Doctrine of Signatures, a historical concept suggesting that a plant's appearance indicates its medicinal use, also played a role in beetroot's reputation. The deep red color of beetroot led to the belief that it was beneficial for the blood. Although the iron content in beetroot is not exceptionally high, the form in which it is present is easily assimilated by the body, contributing to its reputation as a blood tonic.

Nutritional Composition and Caloric Content

The beet family, including sugar beet, is known for being rich in easily digested carbohydrates, while maintaining a relatively low calorie content. When boiled for two hours, red beetroot tends to concentrate its mineral content rather than lose it. However, this process does reduce the vitamin content, which is why beetroot is often consumed in raw juice form for therapeutic purposes.

Beetroot Juice: A Therapeutic Powerhouse

Beetroot juice is known for its stimulating effect on both the nerves of the tongue and the intestines. In Germany, beet juice is widely used in pasteurized form as a powerful restorative during convalescence. It is particularly effective for general weakness and debility. When combined with other juices, such as carrot and cucumber, beetroot juice becomes a potent blood builder and is used to treat sexual weakness, kidney stones, gallbladder issues, and liver and prostate troubles.

The effectiveness of beet juice lies partly in its chlorine content, which helps regulate digestion by controlling peristalsis, the natural rhythmic contractions of the gut. This regulation assists in the assimilation of food, especially during recovery periods.

Practical Considerations in Beetroot Preparation

Uncooked beets have a longer shelf life than many other vegetables. When cooking beets, it is crucial to avoid damaging or cutting the skin, as this will cause the red color to leach into the cooking water, resulting in a pale and unattractive beet. If the skin is accidentally damaged, adding a few drops of lemon juice or cider vinegar to the cooking water can significantly reduce the leakage of color.

Nutritional Value of Beet Tops

The dark green tops of beetroot should not be discarded, as they are rich in carotene and minerals. These tops can be juiced in small quantities as an addition to other juices or steamed to make a nutritious and cost-effective alternative to spinach.

Modern Insights and Ongoing Research

Recent studies have continued to explore the health benefits of beetroot. Research has shown that beetroot juice can improve athletic performance, reduce blood pressure, and enhance cognitive function due to its high nitrate content. These nitrates are converted into nitric oxide in the body, which helps to relax and dilate blood vessels, improving blood flow and oxygen delivery to tissues.

Despite the wealth of knowledge about beetroot, there remains much to discover about its full range of benefits. It remains, after carrot, one of the chief juices in the science of natural healing, valued for its wide range of therapeutic properties and nutritional benefits. As research continues, beetroot's role in natural medicine and health promotion is likely to expand further, unlocking even more of its potent secrets.

Applications and health benefits of beetroot

The beet, Beta vulgaris is a plant in the Chenopodiaceae family having bright crimson colour. It is best known in its numerous cultivated varieties, the most well-known of which is the purple root vegetable known as beetroot or table garden beet.

It is famous for its juice value and medicinal properties; and known by several common names like beet, chard, spinach beet, sea beet, garden beet, and white beet.

Today, beetroot is grown in many countries worldwide, is regularly consumed as part of the normal diet, and commonly used in manufacturing as a food colouring agent known as E162.

The usually deep-red roots of beetroot are eaten boiled either as a cooked vegetable, or cold as a salad after cooking and adding oil and vinegar, or raw and shredded, either alone or combined with any salad vegetable. It also can made into soup, which is popular in many Eastern and Central European countries.

There are huge numbers of red beetroot-based dietary supplements and functional food on the market: juice and juice mixtures (predominantly, with lemon juice), gels, fermented and fractionated juice, dried powder (tablets, capsules, micro-capsulated formulations, crunchy beetroot slices) and beetroot enriched bread.

Beetroots main benefits are that it contains no fat, very few calories and is a great source of fibre. The best quality and root colour are obtained when the air temperature ranges between 10 and 18 ºC. In contrast to fruits, the main sugar in beetroot is sucrose.

Modern pharmacology shows that red beet extracts exhibit antihypertensive and hypoglycaemic activity as well as excellent antioxidant activity.

What are betalains?

Plant pigments have widely different chemical structures. The major chemical types are chlorophylls, carotenoids, anthocyanins and betalains.

Betalains are plant derived natural pigments that are presently gaining popularity for use as natural colorants in the food industry. The growing interest of consumers in the aesthetic, nutritional and safety aspects of food has increased the demand for natural pigments such as betalains to be used as alternative colorants in food products.

The major dietary sources of betalains are not only cactus pear and red and yellow beetroot but also colored Swiss chard and grain or leafy amaranth.

The major commercially exploited betalain crop is red beetroot (Beta vulgaris) because the extract contains mainly betanin, which is approved as a red food colorant E162 in different low-acid and neutral food commodities (pH 3–7) from beverages to candies and from dairy to cattle products by both the European Union and the United States.

According to their chemical structure, betalains can be subdivided into red-violet betacyanins or yellow betaxanthins, with its color ascribed by the betalain structure's resonating double bonds.

Beetroot juice can lower blood pressure

Beetroot and its product are a very good source of the chemical compound nitrate which can dramatically bring down high blood pressure. In fact, when the person consume the juice, the blood pressure drop instantly and stay lowered for up to twenty-four hours.

A study published by American Heart Association Journal shows that is the ingestion of the dietary nitrate in the beetroot juice is ultimately responsible for the lowered blood pressure. The researchers found that blood pressure levels were lowered within only one hour after dirking the beetroot juice.

It was believed by the researchers that nitrates are converted into nitric oxide by the body, and this chemical that eases up the blood vessel. In one study, researchers found that drinking just one glass of beetroot juice lowered systolic pressure by 4 to 5 points.

Research also shown that a daily intake of 300 to 500 (equal to cups of beetroot juice) milligrams of dietary nitrate can improve exercise performance and lower blood pressure.
